MANAGING THE RISK OF FALLS\n\n## 2.1 How to identify fall hazards\n\nYou must identify all locations and tasks that could cause injury due to a fall. This includes access to the areas where work is to be carried out. Tasks that need particular attention are those carried out:\n\n-   on any structure or plant being constructed or installed, demolished or dismantled, inspected, tested, repaired or cleaned\n-   on a fragile surface (for example, cement sheeting roofs, rusty metal roofs, fibreglass sheeting roofs and skylights)\n-   on a potentially unstable surface (for example, areas where there is potential for ground collapse)\n-   using equipment to work at the elevated level (for example, when using elevating work platforms or portable ladders)\n-   on a sloping or slippery surface where it is difficult for people to maintain their balance (for example, on glazed tiles)\n-   near an unprotected open edge (for example, near incomplete stairwells)\n-   near a hole, shaft or pit into which a worker could fall (for example, trenches, lift shafts or service pits).\n\n### Inspect the workplace\n\nWalk around the workplace and talk to your workers to find out where work is carried out that could result in falls. A checklist may be useful in this process. Key things to look for include:\n\n-   surfaces:\n\n-   the stability, fragility or brittleness\n-   the potential to slip, for example where surfaces are wet, polished or glazed\n-   the safe movement of workers where surfaces change\n-   the strength or capability to support loads\n-   the slope of work surfaces, for example, where they exceed 7 degrees.\n\n-   levels—where levels change and workers may be exposed to a fall from one level to another\n-   structures—the stability of temporary or permanent structures\n-   the ground—the evenness and stability of the ground for safe support of scaffolding or a work platform\n-   the working area—whether it is crowded or cluttered\n-   entry and exit from the working area\n-   edges—protection for open edges of floors, working platforms, walkways, walls or roofs\n-   holes, openings or excavations—which will require guarding\n-   hand grip—places where hand grip may be lost.\n\nIn some situations, advice may be needed from technical specialists, such as structural engineers, to check the stability of structures or load bearing capacity.\n\n### Review available information, including incident records\n\nYou should check your records of previous injuries and ‘near miss’ incidents related to falls.\n\nInformation and advice about fall hazards and risks relevant to particular industries and work activities is also available from regulators, industry associations, unions, technical specialists  \nand safety consultants.\n\n## 2.2 How to assess the risk\n\nA risk assessment will help you determine:\n\n-   what could happen if a fall did occur and how likely it is to happen\n-   how severe a risk is\n-   whether any existing control measures are effective\n-   what action you should take to control the risk\n-   how urgently the action needs to be taken.\n\nA risk assessment is unnecessary if you already know the risk and how to control it.\n\nWhen assessing the risks arising from each fall hazard, the following matters should be considered:\n\n-   the design and layout of elevated work areas, including the distance of a potential fall\n-   the number and movement of all people at the workplace\n-   the proximity of workers to unsafe areas where loads are placed on elevated working areas  \n    (for example, loading docks) and where work is to be carried out above people and there is  \n    a risk of falling objects\n-   the adequacy of inspection and maintenance of plant and equipment (for example, scaffolding)\n-   the adequacy of lighting for clear vision\n-   weather conditions—the presence of rain, wind, extreme heat or cold can cause slippery  \n    or unstable conditions\n-   the suitability of footwear and clothing for the conditions\n-   the suitability and condition of ladders, including where and how they are being used\n-   the adequacy of current knowledge and training to perform the task safely (for example, young, new or inexperienced workers may be unfamiliar with a task)\n-   the adequacy of procedures for all potential emergency situations.\n\n### Generic risk assessment\n\nIf you are responsible for a number of different work areas or workplaces and the fall hazards are the same, you may perform a single (or generic) risk assessment. However, you should carry out  \na risk assessment on individual fall hazards if there is any likelihood that a person may be exposed to greater, additional or different risks.\n\n##   \n2.3 How to control the risk\n\nThere are a number of ways to control the risks of falls. Some control measures are more effective than others. Control measures can be ranked from the highest level of protection and reliability to the lowest. This ranking is known as the hierarchy of control. The WHS Regulations require duty holders to work through this hierarchy to choose the control that most effectively eliminates or minimises the risk in the circumstances. This may involve a single control measure or a combination of two or more different controls.\n\nIn managing the risks of falls, the WHS Regulations require the following specific control measures to be implemented, where it is reasonably practicable to do so:\n\n1.  Can the need to work at height be avoided to eliminate the risk of a fall?\n\n-   Carry out any work that involves the risk of a fall on the ground\n\n2. Can the fall be prevented by working on solid construction?\n\n-   A building or structure that is used as an existing place of work and includes safe access and egress from which there is no risk of a fall from one level to another, for example properly constructed stairs with fixed handrails, flat roofs with a parapet or permanently installed guard rails around the edges.\n\nIt is usually not necessary to implement additional control measures to manage the risk of falls  \nfor workplaces in buildings that already comply with the requirements of the National Construction Code of Australia, for example in relation to stairs, mezzanines and balconies.\n\n3. Can the risk of a fall be minimised by providing and maintaining a safe system of work, including:\n\n-   providing a fall prevention device (for example, installing guard rails) if it is reasonably practicable to do so, or\n-   providing a work positioning system (for example, an industrial rope access system)  \n    if it is not reasonably practicable to provide a fall prevention device, or\n-   providing a fall\\-arrest system, so far as is reasonably practicable, if it is not reasonably practicable to provide a fall prevention device or a work positioning system.\n\nIn some cases a combination of control measures may be necessary, for example using a safety harness while working from an elevating work platform.\n\nControl measures are needed where there is a risk of injury irrespective of fall height. For low  \nfalls, you should assess the risk and provide reasonably practicable measures that reflect the risk.  \nFor example, there may be a risk of injury to workers standing on a narrow 1.7 metre high platform next to a production line where they have to work with their back to the open edge or where there is a risk of falling onto an uneven surface with sharp edges or protrusions. In this situation it may be reasonably practicable to install a guard rail along the edge of the platform.\n\nSometimes it may not be reasonably practicable to provide guard rails, for example at the edges  \nof railway platforms or vehicle inspection pits. Other safe systems of work to provide adequate protection should be implemented, for example brightly painted lines to designate edges.\n\nWork of long duration and higher frequency will usually require control measures higher up the hierarchy to provide adequate protection, for example using a mobile scaffold instead of a ladder.\n\nYou should also ensure that the control measures you select do not create new hazards, for example electrical risks from contact with overhead power lines or crushing and entanglement  \nfrom plant such as elevating work platforms.\n\n### Implementing and maintaining control measures\n\nRegulation 37 You must ensure that the control measures you implement remain effective.  \nThis includes checking that the control measures are fit for purpose; suitable for the nature  \nand duration of the work; are installed and used correctly.\n\nTo allow the chosen control measures to operate effectively, you should:\n\n-   develop work procedures on how to correctly install, use and maintain the control measure. The procedures should include a planned program of inspections and maintenance for the control measures. The inspection regime should include details of:\n-   the equipment to be inspected (including its unique identification)\n-   the frequency and type of inspection (pre-use checks, detailed inspections)\n-   action to be taken on finding defective equipment\n-   means of recording the inspections\n-   training of users\n-   the system of monitoring the inspection regime to verify that inspections are carried out appropriately.\n\nThe manufacturer and/or supplier of the equipment should be consulted for any product specific requirements.

Some control measures are more effective than others. Control measures can be ranked from the highest level of protection and reliability to the lowest. This ranking is known as the hierarchy of control. The WHS Regulations require duty holders to work through this hierarchy to choose the control that most effectively eliminates or minimises the risk in the circumstances. This may involve a single control measure or a combination of two or more different controls.\n\nIn managing the risks of falls, the WHS Regulations require the following specific control measures to be implemented, where it is reasonably practicable to do so:\n\n1.  Can the need to work at height be avoided to eliminate the risk of a fall?\n\n-   Carry out any work that involves the risk of a fall on the ground\n\n2. Can the fall be prevented by working on solid construction?\n\n-   A building or structure that is used as an existing place of work and includes safe access and egress from which there is no risk of a fall from one level to another, for example properly constructed stairs with fixed handrails, flat roofs with a parapet or permanently installed guard rails around the edges.\n\nIt is usually not necessary to implement additional control measures to manage the risk of falls  \nfor workplaces in buildings that already comply with the requirements of the National Construction Code of Australia, for example in relation to stairs, mezzanines and balconies.\n\n3. Can the risk of a fall be minimised by providing and maintaining a safe system of work, including:\n\n-   providing a fall prevention device (for example, installing guard rails) if it is reasonably practicable to do so, or\n-   providing a work positioning system (for example, an industrial rope access system)  \n    if it is not reasonably practicable to provide a fall prevention device, or\n-   providing a fall\\-arrest system, so far as is reasonably practicable, if it is not reasonably practicable to provide a fall prevention device or a work positioning system.\n\nIn some cases a combination of control measures may be necessary, for example using a safety harness while working from an elevating work platform.\n\nControl measures are needed where there is a risk of injury irrespective of fall height. For low  \nfalls, you should assess the risk and provide reasonably practicable measures that reflect the risk.  \nFor example, there may be a risk of injury to workers standing on a narrow 1.7 metre high platform next to a production line where they have to work with their back to the open edge or where there is a risk of falling onto an uneven surface with sharp edges or protrusions. In this situation it may be reasonably practicable to install a guard rail along the edge of the platform.\n\nSometimes it may not be reasonably practicable to provide guard rails, for example at the edges  \nof railway platforms or vehicle inspection pits. Other safe systems of work to provide adequate protection should be implemented, for example brightly painted lines to designate edges.\n\nWork of long duration and higher frequency will usually require control measures higher up the hierarchy to provide adequate protection, for example using a mobile scaffold instead of a ladder.\n\nYou should also ensure that the control measures you select do not create new hazards, for example electrical risks from contact with overhead power lines or crushing and entanglement  \nfrom plant such as elevating work platforms.","sortOrder":15},{"sectionNumber":"Implementing and maintaining control mea","sectionType":"division","heading":"Implementing and maintaining control measures","content":"### Implementing and maintaining control measures\n\nRegulation 37 You must ensure that the control measures you implement remain effective.  \nThis includes checking that the control measures are fit for purpose; suitable for the nature  \nand duration of the work; are installed and used correctly.\n\nTo allow the chosen control measures to operate effectively, you should:\n\n-   develop work procedures on how to correctly install, use and maintain the control measure.

WORK ON THE GROUND OR ON A SOLID CONSTRUCTION\n\n## 3.1 Work on the ground\n\nEliminating the need to work at height is the most effective way of protecting workers from the risk of falls. Examples of eliminating the risk by working on the ground include:\n\n-   prefabricating roofs at ground level\n-   prefabricating wall frames horizontally, then standing them up\n-   using mechanical tarp spreaders to cover loads on trucks from the ground\n-   fitting outlets, inlets and controls of large tanks and silos near the ground (see Figure 1)\n-   reducing shelving heights so that workers can access items from ground level\n-   using tools with extendable handles, such as paint rollers (the risk of musculoskeletal disorders will need to be considered when deciding whether to use such tools)\n-   installing windows that pivot to enable cleaning from a safe position inside a building\n-   lowering a concert hall chandelier to repair it.\n\nFigure 1: A silo showing sight glass and ground delivery tube\n\n![Figure 1 is a silo showing sight glass and a ground delivery tube.](image.002.jpeg)\n\n## 3.2 Work on a solid construction\n\nWorking on a solid construction provides an environment where the likelihood of a fall may be eliminated. ‘Solid construction’ means an area that:\n\n-   is structurally capable of supporting workers, material and any other loads applied to it\n-   is provided with barriers around its perimeter and around any openings from or through  \n    which a person could fall\n-   has an even, accessible surface and gradient\n-   has a safe means of entry and exit.\n\n### Structural strength\n\nDifferent types of work involve different loads on the supporting surface. The surface and its supports must be able to safely carry the expected loads, including workers, materials, tools and equipment. When in doubt, have a structural engineer determine the safe load capacity before use.\n\n### Barriers\n\nBarriers (or edge protection) to prevent a person falling over edges and into holes should be provided on relevant parts of a solid construction. These include:\n\n-   the perimeters of buildings or other structures\n-   mezzanine floors (see Figure 2)\n-   openings in floors\n-   the open edge of a stair, landing, platform or shaft opening (see Figure 3).\n\nFigure 2: A barrier on a mezzanine floor\n\n![Figure 2 shows a barrier on the mezzanine floor.](image.003.jpeg)\n\nFigure 3: A platform with guard rails installed above silos\n\n![ Figure 3 shows a platform with guard rails installed above silos.](image.004.jpeg)\n\nThe barrier should be designed and constructed to withstand the force of someone falling  \nagainst it.\n\nEdge protection should consist of guard rails, solid balustrades or other structural components,  \nfor example wire mesh supported by posts and provided with a reinforced top edge. The top of the guard rail or component should be between 900 mm and 1100 mm above the working surface. If  \na guard rail system is used, it should also have mid\\-rails and toe boards or wire mesh infill panels.\n\nIf access is required to equipment (for example, a hoist) it should be protected with gates, safety chains or other means to prevent a person falling.\n\n### Protection of openings and holes\n\nHoles, penetrations and openings through which a person could fall should be made safe immediately after being formed.\n\nIf a cover is used as a control measure, it must be made of a material that is strong enough to prevent persons or objects falling through and must be securely fixed to prevent any dislodgement or accidental removal.\n\nFigure 4: 4 mm mesh embedded in the concrete floor. The hole should also be covered to prevent things falling through.\n\n![Figure 4 shows 4mm mesh embedded in a concrete floor. ](image.005.jpeg)\n\nFigure 5: Example of the type of danger sign to be affixed to the hole cover\n\n![Figure 5 shows an example of the type of danger sign to be affixed to a hole cover.](image.006.jpeg)\n\n### Surface and gradient\n\nSurfaces of solid construction should be non-slip, free from trip hazards and should generally not exceed 7 degrees (1 in 8 gradient). Cleated surfaces, which provide greater slip-resistance, should not be steeper than 20 degrees (1 in 3 gradient).\n\nIf grid mesh or checker plate flooring is used for walkways and working platforms, ensure that:\n\n-   flooring panels are securely fixed and assembled in accordance with manufacturer’s specifications\n-   where possible, they are fitted to the structure prior to it being lifted into permanent position\n-   each panel is fixed securely before the next panel is placed in position\n-   during installation, this type of flooring is secured by tack welding, panel grips or other means to prevent movement before being fixed permanently\n-   if panels of grid mesh or checker plate flooring are removed, edge protection is provided and the gaps left due to removed panels are protected.\n\n### Entry and exit\n\nThe solid construction must have a safe means for people to get to, from and move around the work area, for example permanently installed platforms, ramps, stairways and fixed ladders.\n\nFurther guidance is available in AS 1657 Fixed platforms, walkways, stairways and ladders – Design, construction and installation.\n\nSafety considerations include:\n\n-   exposure of access systems to the weather (for example, rain can make surfaces slippery and strong winds can cause loss of hand grip)\n-   the provision of adequate natural or artificial lighting to all access ways\n-   the clearance of obstructions so that persons are able to move easily to and from the workplace.\n\nPortable ladders should only be used where the use of safer systems is not reasonably practicable.\n\n#   \n4\\. FALL PREVENTION DEVICES\n\nA fall prevention device is any equipment that is designed to prevent a fall for temporary work at heights, and once in place does not require any further adjustment by workers using the device.\n\n## 4.1 Temporary work platforms\n\nA ‘temporary work platform’ is a working platform, other than a permanently installed fixed platform, used to provide a working area for the duration of the job. The design of the platform prevents workers from falling. Temporary work platforms include scaffolds, elevating work platforms, mast climbers, workboxes, building maintenance units, portable or mobile fabricated platforms or any other platform that provides a working area and is designed to prevent a fall.\n\n### Scaffolding\n\nScaffolding can be very effective protection in preventing falls; however, there are specific requirements that apply to some types of scaffold under the WHS Regulations.\n\nRegulation 225: A person with management or control of a scaffold must not allow the use  \nof a scaffold from which a person or object could fall more than four metres unless a competent person provides written confirmation that the scaffold has been completed. The person must  \nalso ensure that:\n\n-   the scaffold and its supporting structure is inspected by a competent person before use,  \n    after any incident that could affect its stability (such as a severe storm), after any repairs,  \n    and at least every 30 days\n-   unauthorised access is prevented on scaffolding that is incomplete and left unattended  \n    (for example, by attaching danger tags and warning signs at appropriate locations).\n\nScaffolding work platforms are generally rated as light, medium or heavy duty. Safety considerations include:\n\n-   scaffolding conforms to AS/NZS 4576 Guidelines for scaffolding and the AS/NZS 1576 Scaffolding series\n-   all scaffolding is erected, altered and dismantled by competent persons. Any scaffold from which a person or object could fall more than four metres must be erected, altered and dismantled by or under the direct supervision of a licensed scaffolder.\n-   prefabricated scaffolds are of the same type and not mixed components, unless the mixing  \n    of components has been approved by the manufacturer\n-   safe access to and egress from the scaffold is provided\n-   edge protection (hand rails, mid-rails and toe boards) is provided at every open edge of  \n    a work platform (see Figure 5).\n\nInformation, instruction and training for workers using scaffolds\n\nWhere work is performed from a scaffold, you must ensure that the relevant workers understand:\n\n-   what loads the scaffold can safely take\n-   not to make any unauthorised alterations to the scaffold (such as removing guard rails, planks, ties, toe boards and braces)\n-   that working platforms need to be kept clear of debris and obstructions along their length, and\n-   that incomplete or defective scaffolds must never be accessed.\n\n  \nWhere work is performed using mobile scaffolds, workers should be trained to ensure the scaffold:\n\n-   remains level and plumb at all times\n-   is kept well clear of powerlines, open floor edges and penetrations\n-   is not accessed until the castors are locked to prevent movement\n-   is never moved while anyone is on it\n-   is only accessed using internal ladders (see Figure 7).\n\nFigure 6: Perimeter scaffold with a fully decked working platform, guardrails and toeboards.\n\n![Figure 6 shows a perimeter scaffold with a fully decked working platform, guardrails and toeboards.](image.007.jpeg)\n\nFigure 7: Mobile scaffold with an access ladder and trapdoor to provide the largest possible hazard-free working platform.\n\n![Figure 7 shows a mobile scaffold with an access ladder and trapdoor to provide the largest possible hazard-free working platform.](image.008.jpeg)\n\n### Light duty suspended scaffold\n\nA suspended scaffold incorporates a suspended platform that is capable of being raised or lowered when in use (see Figure 8). Common types of suspended scaffolds include:\n\n-   swing stages which have cradles supported by a single row of suspension ropes\n-   double rope scaffolds, with cradles supported by two rows of suspension ropes\n-   work cages which are small cradles supported by one suspension rope only\n-   false cars, which are specialised forms of suspended scaffolding and are often used in the construction of lifts before lift cars are installed.\n\nThere are specific safety considerations for swing stages, including that:\n\n-   the working load and specifications are in accordance with AS 1576.4 Scaffolding – Suspended Scaffolding\n-   persons operating light duty suspended stages are trained in safe operation\n-   persons installing or servicing a light duty suspended stage hold a licence for advanced rigging or advanced scaffolding\n-   where the swing stage is suspended by two wire ropes to each winch, a safety harness and restraint lanyard is attached to a suitable anchor point of the swing stage.\n\nFurther guidance on the safe design, erection and use of scaffolding, including suspended scaffolding, is available in the Scaffolding Code of Practice \\[under development\\].\n\nFigure 8: Example of a light duty suspended scaffold with two wire ropes to each winch.  \nThe platform must remain horizontal when moving it up or down.\n\n![Figure 8 shows an example of a light duty suspended scaffold with two wire ropes to each winch. ](image.009.jpeg)\n\n### Elevating work platforms\n\nElevating Work Platforms (EWPs) include scissor lifts, cherry pickers, boom lifts and travel towers. There are battery powered and internal combustion engine types. Some are designed for hard flat surfaces only, while others are designed to be operated on rough terrain.\n\nSafety considerations include that:\n\n-   workers operating the platform are trained and instructed in safe operating procedures for the particular brand and type of equipment, as well as the safe use of fall\\-arrest equipment and emergency rescue procedures\n-   the platforms are only used as working platforms and not as a means of entering and exiting a work area unless the conditions set out in [AS 2550.10 Cranes, hoists and winches - Safe use - Mobile elevating work platforms](http://www.saiglobal.com/online/Script/Details.asp?DocN=AS0733778984AT \"click here to see details of this document\") are met\n-   unless designed for rough terrain, the platforms are used only on a solid level surface\n-   the surface area is checked to make sure that there are no penetrations or obstructions that could cause uncontrolled movement or overturning of the platform\n-   the manufacturer’s or supplier’s instructions are consulted for information on safe operation\n-   persons working in travel towers, boom lifts or cherry pickers wear a properly anchored safety harness  \n    \n-   workers are licensed when operating boom-type elevating work platforms with a boom length of 11 metres or more.\n\nFigure 9: An example of a boom-type elevating work platform. The safety harness and lanyard assembly are not shown for purposes of clarity. The lanyard should be as short as possible and should be attached directly to the designated anchor point on the EWP, not to the handrail.\n\n![Figure 9 shows an example of a boom-type elevating work platform. ](image.010.png)\n\nFigure 10: An example of a scissor-lift elevating work platform.\n\n![Figure 10 shows an example of a scissor-lift elevating work platform.  ](image.011.png)\n\n### Mast climbing work platforms\n\nMast climbing work platforms are hoists with a working platform that is used to raise workers and material to a temporary working position. They use a drive system mounted on an extendable mast, which may need to be tied to a building under circumstances prescribed by the manufacturer.\n\nMast climbing work platforms can be set up in either single-mast or multi-mast configurations.  \nThey are generally not suitable for use if the profile of a structure changes at different elevations (for example, if the upper floors of a building ‘step’ back or balconies protrude from the building).\n\nThe erection and dismantling of mast climbing work platforms must be carried out, or be directly supervised, by a person holding an appropriate rigging or scaffolding licence.\n\nFurther information on mast climbing work platforms is provided in AS 2550.16 Cranes—Safe Use—Mast climbing work platforms.  \n\nFigure 11: An example of a typical mast climbing work platform.\n\n![Figure 11 shows an example of a typical mast climbing work platform.](image.012.png)\n\n### Workboxes\n\nA workbox is designed to be supported by a crane, hoist, forklift truck or other mechanical device to provide an elevated work area for persons working from the box. It consists of a platform surrounded by an edge protection system and should be designed in accordance with AS 1418.17 Cranes (including hoists and winches) —Design and construction of workboxes.\n\nWhere reasonably practicable, other working platforms, such as an elevating working platform  \nor scaffold, should be used as an alternative to the workbox.\n\nThe safety requirements and considerations include that:\n\n-   the workbox is not suspended over persons\n-   the workbox is designed for the task and securely attached to the crane. The workbox, lifting attachments and records should be checked by a competent person before use\n-   the workbox is fitted with a suitable anchorage capable of withstanding the fall forces specified in AS/NZS 1891.4 Industrial fall-arrest systems and devices—Selection, use and maintenance. Workers must be attached to the anchorage by a lanyard and harness unless the workbox is fully enclosed\n-   workers remain within the workbox while they are being lifted or suspended\n-   workers do not enter or leave the workbox when it is suspended (except in an emergency)\n-   the crane is fitted with the means to safely lower it in an emergency or a power supply failure\n-   the crane is suitably stabilised at all times while the workbox is used\n-   the crane has ‘drive up’ and ‘drive-down’ controls on both the hoisting and luffing motions  \n    and those controls are used. No declutching allowing free fall is to be used while a workbox  \n    is in use\n-   an effective means of communication between any person in the workbox and the operator  \n    is provided\n-   the crane is fitted with a safety hook and moused (lashed) accordingly\n-   the operator remains at the controls of the crane at all times.  \n    \n\nFor specifications for the use of crane workboxes refer to AS 2550.1 Cranes, Hoists and Winches—Safe Use—General Requirements.\n\nForklifts with a work box\n\nA workbox fitted to a forklift must be securely attached to the forklift carriage and engineer-designed and constructed in accordance with AS 2359 Powered Industrial Trucks (see Figure 12).\n\nSafety considerations include that:\n\n-   people are not raised on the tynes of forklift trucks or the pallet\n-   no other device (for example, ladder or pallets) is used to gain additional height (see Figures 13 and 14)\n-   the safety gate is self-locking and kept shut when in the elevated position.\n\nFigure 12: An example of an engineer-designed workbox with safety harness and lanyard assembly, correctly positioned on the forklift tynes.\n\n![Figure 12 shows an example of an engineer-designed workbox with safety harness and lanyard assembly, correctly positioned on the forklift tynes.](image.013.jpeg)\n\nFigure 13: Using a forklift as a working platform or to gain extra height by standing  \non the tynes or a pallet is an unacceptable practice.\n\n![Figure 13 shows the unacceptable practice of using a forklift as a working platform.\n](image.014.jpeg)  \n\nFigure 14: Unacceptable practice with ladder on forklift.\n\n![Figure 14 shows an unacceptable practice of using a ladder on a forklift.](image.015.jpeg)\n\n### Building maintenance units\n\nDesigners of buildings should consider the methods by which maintenance, repairs or cleaning  \nwill be undertaken on buildings or structures.\n\nA building maintenance unit is a power-operated suspended working platform that is fixed permanently to a building or structure. It is used for access for building maintenance or window cleaning (see Figure 15).\n\nFigure 15: An example of a building maintenance unit with safety harness and restraint line.\n\n![Figure 15 shows an example of a building maintenance unit with safety harness and restraint line.](image.016.jpeg)\n\nSafety considerations include that:\n\n-   the platform has sufficient, clearly designated safety harness anchorage points designed  \n    to withstand the forces caused by a fall of any person located anywhere on the platform\n-   the units are designed in accordance with AS 1418.13 Cranes (including Hoists and Winches) —Building Maintenance Units and operated by competent persons in accordance with AS 2550.13 Cranes—Safe Use—Building Maintenance Units.\n\n### Platforms supported by trestle ladders\n\nTrestle ladder scaffolds are only suitable for use at heights greater than two metres when guard rails and toe boards are incorporated to prevent people and material falling off the working platform. The system (including planks) should be assembled according to the manufacturer’s specifications with the complete set of compatible components.\n\nSome trestle ladder scaffolds include outriggers to increase stability (see Figure 16). Trestle ladder scaffolds are only suited to light duty tasks such as painting and rendering. Work should only be performed between the trestles. The minimum width of the working platform should not be less than 450 mm.\n\nAlternatives to trestle ladders should be considered, such as small scissor lifts, light duty aluminium mobile scaffolds, boom arms and modular scaffolding.\n\nFigure 16: Trestle ladder scaffold with guard rails and outriggers for stability.\n\n![Figure 16 shows a trestle ladder scaffold with guard rails and outriggers for stability.](image.017.jpeg)\n\n## 4.2 Perimeter guard rails\n\nGuard rails may be used to provide effective fall prevention:\n\n-   at the edges of roofs\n-   at the edges of mezzanine floors, walkways, stairways, ramps and landings\n-   on top of plant and structures where access is required (see Figure 17)\n-   around openings in floor and roof structures\n-   at the edges of shafts, pits and other excavations.\n\nGuard rails should incorporate a top rail 900mm to 1100 mm above the working surface and a mid rail and a toe board.\n\nBefore using a guard rail system you should check that it will be adequate for the potential loads. The required load resistance will depend on the momentum of a falling person. For example, the momentum of a person falling from a pitched roof will increase as the pitch (or angle) of the roof increases.\n\nRefer to AS/NZS 4994—Temporary Edge Protection series for further guidance.\n\nFigure 17: Guard rails installed on top of a tanker to enable safe access to tank hatches.\n\n![Figure 17 shows guard rails installed on top of a tanker to enable safe access to tank hatches.](image.018.jpeg)\n\n## 4.3 Safety mesh\n\nSafety mesh is designed to prevent internal falls through a roof. If securely fixed, safety mesh provides fall protection for roof installers and offers long-term protection against falling for maintenance and repair workers.\n\nSafety mesh does not prevent falls from the edge of a roof or through holes in a roof, so it should always be used in conjunction with appropriate edge protection, guard rails or fall-arrest systems.\n\nSafety mesh should comply with AS/NZS 4389 Safety mesh, which specifies the minimum requirements for the design, construction, testing and installation of safety mesh for use in domestic, commercial and industrial building applications.\n\nThe mesh should be formed from 2 mm diameter wire of not less than 450 MPa tensile strength, welded into a mesh with the longitudinal wires not more than 150 mm apart and the cross wires  \nnot more than 300 mm apart.\n\nSafety mesh should be installed in accordance with the manufacturer’s instructions by competent persons, who should be protected against the risk of falling by using appropriate control measures such as scaffolding, elevating work platforms or fall\\-arrest systems.\n\nParticular care is required to ensure that the mesh is securely connected to the structure and the overlap between adjacent sections of mesh is sufficient to generate the necessary strength to resist the force of a person falling onto it. The safety mesh should be covered by the roof cladding as soon as reasonably practicable after it has been installed.\n\n#   \n5. WORK POSITIONING SYSTEMS\n\nA work positioning system involves the use of equipment that enables a person to work supported in a harness in tension in such a way that a fall is prevented.\n\nWork positioning systems require a high level of competency on the part of the user and supervisors to ensure safe use. Users, including supervisors, should undertake a competency based course of training.\n\n## 5.1 Industrial rope access systems\n\nIndustrial rope access systems are used for gaining access to and working at a workface, usually by means of vertically suspended ropes. Although fall\\-arrest components are used in the industrial rope access system, the main purpose of the system is to gain access to a work area rather than to provide backup fall protection (see Figure 18).\n\nOther methods of accessing a workface should be considered (for example, EWPs or building maintenance units) before rope access systems, as a high level of skill is needed for their safe use.\n\nYou should ensure that, where it is necessary for industrial rope access systems to be used:\n\n-   operators are competent in the technique\n-   operators do not work alone, in case they require assistance in an emergency\n-   industrial rope access systems are installed only in a location where it is possible to provide prompt assistance or rescue if required (refer to Chapter 9 of this Code)\n-   all equipment is checked regularly by a competent person\n-   prior to use, all fixed anchorage points are checked by a competent person before attaching the rope access lines\n-   a back up system is used to protect the operator\n-   two independently anchored ropes are used for each person\n-   any person within three metres of an unguarded edge is adequately secured\n-   all operators wear a full body harness\n-   supervisors can communicate with workers\n-   where necessary, appropriate personal protective equipment is used, such as helmets, gloves, hearing protection, goggles and masks\n-   barricades and signposts are placed on all access areas below the working area and anchorage locations to exclude and alert the public and tradespeople.\n\nFurther guidance on industrial rope access systems is available in AS/NZS 4488 Industrial rope access systems series.\n\n  \nFigure 18: Operator using an ascender in an industrial rope access system.\n\n![Figure 18 shows an operator using an ascender in an industrial rope access system. ](image.019.jpeg)\n\n## 5.2 Restraint technique\n\nA restraint technique controls a person’s movement by physically preventing the person reaching  \na position at which there is a risk of a fall. It consists of a harness that is connected by a lanyard  \nto an anchorage or horizontal life line. It must be set up to prevent the wearer from reaching an unprotected edge (see Figure 19).\n\nFigure 19: Restraint technique options.\n\n![Figure 19 shows restraint technique options.](image.020.png)\n\nA restraint technique is suitable for use where:\n\n-   the user can maintain secure footing without having to tension the restraint line and without  \n    the aid of any other hand hold or lateral support. When deciding whether secure footing can  \n    be maintained, consider:\n\n-   the slope of the surface\n-   the supporting material type\n-   the surface texture of the surface and whether it is likely to be wet, oily or otherwise slippery\n\n-   the horizontal life lines are fitted with an industrial shock absorber when required\n-   the restraint system conforms with AS/NZS 1891 Industrial fall-arrest systems and devices series.\n\nRestraint techniques should only be used if it is not reasonably practicable to prevent falls by providing a physical barrier (for example, a guard rail). This is because restraint techniques require a high level of user skill to operate safely and also greater supervision.\n\nA restraint system should be installed by a competent person in accordance with the manufacturer’s instructions. Restraint anchorage should be designed for fall-arrest loading.\n\nAn individual fall\\-arrest system should be used instead of restraint techniques if any of the following situations apply:\n\n-   the user can reach a position where a fall is possible\n-   the user has a restraint line that can be adjusted in length so that a free fall position can be reached\n-   there is a danger the user may fall through the surface, for example fragile roofing material\n-   the slope is over 15 degrees\n-   there is any other reasonably likely use or misuse of the system that could lead to a free fall.\n\n#   \n6. FALL\\-ARREST SYSTEMS\n\nA fall\\-arrest system is intended to safely stop a worker falling an uncontrolled distance and reduce the impact of the fall. This system must only be used if it is not reasonably practicable to use higher level controls or if higher level controls might not be fully effective in preventing a fall on their own.\n\nAll equipment used for fall\\-arrest should be designed, manufactured, selected and used in compliance with the AS1891 series of standards.\n\nKey safety considerations in using fall arrest systems are:\n\n-   the correct selection, installation and use of the equipment\n-   that the equipment and anchorages are designed, manufactured and installed to be capable of withstanding the force applied to them as a result of a person’s fall\n-   that the system is designed and installed so that the person travels the shortest possible distance before having the fall stopped\n-   that workers using a fall\\-arrest system wear adequate head protection to protect them in the event of a fall\n-   that if the equipment has been used to arrest a fall it is not used again until it has been inspected and certified by a competent person as safe to use.\n\n## 6.1 Catch platforms\n\nA catch platform is a temporary platform located below a work area to catch a worker in the event of a fall. The platform should be of robust construction and designed to withstand the maximum potential impact load. Scaffolding components may be used to construct fixed and mobile catch platforms (see Figure 20).\n\nCatch platforms should:\n\n-   incorporate a fully planked-out deck\n-   be positioned so the deck extends at least two metres beyond all unprotected edges of the work area, except where extended guard railing is fitted to the catch platform\n-   be positioned as close as possible to the underside of the work area—the distance a person could fall before landing on the catch platform should be no more than one metre\n-   always be used with an adequate form of edge protection.\n\nFigure 20: An example of a catch platform below a work area.\n\n![Figure 20 shows an example of a catch platform below a work area.](image.021.jpeg)\n\n## 6.2 Industrial safety nets\n\nSafety nets can provide a satisfactory means of protection while allowing workers maximum freedom of movement. They should not be used to enter or exit a work area or as a working platform.\n\nIf safety nets are used, you should ensure that:\n\n-   safety nets are securely anchored before any work starts\n-   safety nets are constructed of material strong enough to catch a falling person or thing\n-   safety nets are hung as close as is practicable to the underside of the working area, but  \n    no more than two metres below the working area\n-   perimeter safety nets used where there is no edge protection extend at least 2.5 metres beyond the leading edge of the working area\n-   the safety net has sufficient tension and clearance to prevent a falling person contacting  \n    any surface or structure below the net\n-   material is not allowed to accumulate in suspended safety nets\n-   no welding or oxy cutting is performed above safety nets\n-   safety nets are inspected, particularly after installation, relocation or repair\n-   safety nets are stored correctly in dry, shaded areas with good air circulation.\n\n## 6.3 Individual fall\\-arrest systems\n\nIndividual fall\\-arrest systems consist of some or all of the following components:\n\n-   anchorages\n-   lifelines\n-   inertia reel\n-   lanyard of fixed length\n-   retractable lifelines\n-   rope grabs\n-   wire grabs\n-   rail system\n-   shock absorbers, both personal and industrial\n-   harness\n-   snap hooks (double or triple action to prevent rollout)\n-   karabiners (double or triple action to prevent rollout)\n-   rescue equipment.\n\nIndividual fall\\-arrest systems rely on workers wearing and using them correctly, and therefore workers who will use such a system must be trained in its safe use. They should only be used where it is not reasonably practicable to use higher level control measures.\n\nRelevant Australian/New Zealand Standards for personal fall-arrest equipment require that they be permanently marked or labelled to indicate their purpose, correct use, limitations and other relevant information aimed at reducing misuse of the equipment.\n\n### Anchorage points\n\nEach anchorage point should comply with the requirements in AS/NZS 1891:4 Industrial fall-arrest systems and devices – selection, use and maintenance.\n\nAll anchorages should be tested and approved by a competent person before use—a visual inspection may not reveal the structural integrity of the anchor point (i.e. the bolt may have failed below the concrete surface).\n\nEach anchorage point should be located so that a lanyard of the system can be attached to  \nit before the person using the system moves into a position where the person could fall.\n\nInspect the system components\n\nEach component of the system and its attachment to an anchorage must be inspected by  \na competent person:\n\n-   after it is installed but before it is used\n-   at regular intervals\n-   immediately after it has been used to arrest a fall.\n\nInspection of all components should be conducted in accordance with the manufacturer’s specifications and the relevant standards. If any signs of wear or weakness are found during the inspection, the components or means of attachment should be withdrawn from use until they are replaced with properly functioning components.\n\nLimit free fall distance\n\nFall\\-arrest systems, incorporating a lanyard, should be installed so that the maximum distance  \na person would free fall before the fall\\-arrest system takes effect is two metres. There should  \nbe sufficient distance between the work surface and any surface below to enable the system, including the action of any shock absorber to fully deploy (see Figure 21). To work out whether there is enough distance available, you should take into account:\n\n-   the worker’s height\n-   the height and position of the anchorage point\n-   the length of the lanyard\n-   any slack in the horizontal life line\n-   any stretching of the lanyard or horizontal life line when extended by a fall\n-   the length of the energy absorber when extended by a fall.\n\n  \nFigure 21: Total fall distance before this particular configuration would be effective in arresting  \na fall is 6.5m.\n\n![Figure 21 shows that the total fall distance before this particular configuration would be effective in arresting a fall, is 6.5m.](image.022.jpeg)  \n  \nLanyards should not be used in conjunction with inertia reels as this can result in an excessive amount of free fall prior to the fall being arrested.\n\n### Use suitable harnesses\n\nIn most cases, a full body harness should be worn. Harnesses must be correctly fitted. Workers should connect the fall-arrest line to the attachment point on their harness (dorsal attachment point or the chest connection) that will provide the best protection in the situation it is being used. Consideration should be given to the potential fall distance, potential impact with the structure, body position after a fall and the need to interact with equipment such as rope-grabs.\n\n### Maintain minimum of slack in fall\\-arrest lanyard\n\nThere should be a minimum of slack in the fall\\-arrest lanyard between the user and the attachment. The anchorage point should be as high as the equipment permits. Avoid work above the anchor point, as this will increase the free fall distance in the event of a fall, resulting in higher forces on the body and greater likelihood of the lanyard snagging on obstructions.\n\n### Use inertia reels correctly\n\nWhen considering the use of inertia reels, bear in mind that they might not be effective in certain situations. For example, if a worker falls down the inclined surface of a steeply pitched roof, the inertia reel line may keep extending from the reel—it may not lock.\n\nInertia reels should not be used as working supports by locking the system and allowing it to support the user during normal work. They are not designed for continuous support.\n\nVertical and self-retracting anchorage lines can be used as a risk control measure in connection with work performed from boatswains’ chairs and ladders. Where such lines are used, only one person may be attached to any one line.\n\n### Use compatible components\n\nThe use of non-compatible components may lead to ‘roll-out’ with some hook/karabiner configurations, resulting in injury or death to the user. The hazard cannot always be avoided by using components produced by the same manufacturer under the one brand name. If you are unsure whether components of a fall\\-arrest system are compatible you should contact the manufacturer for further information.\n\nSnap hooks should be of the double action type, requiring at least two consecutive deliberate actions to open. Snap hooks should not be connected to each other as this could prevent the safe operation of the snap hook (for example, roll-out may occur). Some double action hooks are susceptible to roll-out. Screw gate karabiners or hex nut connectors may sometimes be appropriate. Further guidance is provided in AS/NZS 1891 Industrial fall-arrest systems and devices.\n\nFigure 22: Roll-out on a small diameter eyebolt.\n\n![Figure 22 shows a roll-out on a small diameter eyebolt. ](image.023.jpeg)\n\n### Ensure prompt rescue in event of fall\n\nA person conducting a business or undertaking who implements a fall\\-arrest system as a control measure must establish emergency and rescue procedures. The rescue of a worker who is suspended in a full body harness must occur promptly to prevent suspension intolerance.\n\nA worker should not use a fall-arrest system unless there is at least one other person on the site who can rescue them if they fall.\n\n### Hazards with individual fall-arrest systems\n\nIf a person using an individual fall-arrest system falls, the system may act as a pendulum, and in some situations the user may hit the ground (called ‘swing down’: see Figure 23) or swing back onto the building or structure (which is called ‘swing back’: see Figure 24).\n\nSwing down can occur if the lanyard slides back along the perimeter edge of the roof until it is vertical. When this happens, the person may hit the ground, or the lanyard may break as a result of its contact with the edge of the roof. Measures to address ‘swing down’ include:\n\n-   the installation of guard rails\n-   placing the anchorage point at a right angle to the position of the lanyard at the perimeter edge (for example, by using a mobile anchorage)\n-   the installation of a second anchorage point and belay devices (intermediate anchorages).\n\n  \nFigure 23: During ‘swing down’ the length of the lanyard and positioning of the anchor allow contact with the ground.\n\n![Figure 23 shows that during ‘swing down’ the length of the lanyard and positioning of the anchor allow contact with the ground.](image.024.png)\n\nFigure 24: During ‘swing back’ the length of the lanyard and positioning of the anchor contact may allow the worker to hit the structure.\n\n![Figure 24 shows that during ‘swing back’ the length of the lanyard and positioning of the anchor contact may allow the worker to hit the structure. ](image.025.png)\n\n## 6.4 Anchorage lines or rails\n\nAnchorage lines or rails are temporary or permanent fall\\-arrest systems, which can be installed  \nto provide continuous fall protection for persons using ladders or climbing towers. These can  \nbe used on plant, such as tower cranes, as well as buildings or structures.\n\nSafety considerations include that:\n\n-   temporary systems comply with the AS/NZS 1891 series of standards\n-   the locking device is attached to the frontal attachment point of the harness and the lanyard assembly is a maximum of 300 mm length\n-   the point of connection onto the ladder by the climber is near the base of the ladder to allow the connection before ascending begins and also to provide continuous connection to the disconnecting point when at a safe higher level\n-   free fall is limited to a maximum of 600 mm\n-   permanent systems are of wire or rail construction and are installed according to the manufacturer’s instructions\n\nAfter a fall, remove the system from service and have it inspected by a competent person before  \nit is used again.  \n\nFigure 25: With the use of an anchorage line system, the person climbing has continuous fall protection by being attached to the anchorage line and harness.\n\n![Figure 25 shows that with the use of an anchorage line system, the person climbing has continuous fall protection by being attached to the anchorage line and harness.](image.026.jpeg)\n\n### Double lanyards\n\nAn alternative to anchorage lines or rails is the use of a double lanyard (also known as a twin tail  \nor ‘Y’ lanyard). Figure 26 shows how the use of a double lanyard means that the person climbing can always be connected to the ladder or structure.\n\nHowever, double lanyards are easy to misuse—there should be no back hooking, they should  \nnot be wrapped around the body or passed between the legs, the chest connection should never be higher than the highest attachment point, they are not suitable for frequent use (because of possible misuse or muscle injury) and the ladder or structure points must be capable of arresting forces generated by a fall with the double lanyard. Adequate training should be provided on  \ntheir use.\n\nFigure 26: Left: An example of a double lanyard. These must have double action connectors.\n\n![Figore 26 shows on the Left: An example of a double lanyard. These must have double action connectors. \nOn the Right: A person climbing with a double lanyard. \n](image.027.jpeg)\n\nRight: Person climbing with a double lanyard. Note that in this application the connectors will slide  \ndown to the lowest point on the rail and likely be subject to side loading. Side loading can be controlled  \nby using soft connections such as slings or the use of hooks rated to withstand side loading.\n\n#   \n7. LADDERS\n\nLadders are primarily a means of access and egress. Many falls take place when people are working from ladders. In addition, when using a ladder:\n\n-   the working width and movement is limited\n-   the time involved in moving and setting up ladders is often underestimated when planning work\n-   the working position on ladders is often uncomfortable (the need to stretch sideways,  \n    work above shoulder height and stand on narrow rungs for a long time) and may cause musculoskeletal disorders.\n\nFor these reasons, you should consider whether an elevating work platform or scaffolding would  \nbe safer and more efficient.\n\n## 7.1 Portable ladders\n\nExtension or single ladders should generally only be used as a means of access to or egress from a work area. They should only be used as a working platform for light work of short duration that can be carried out safely on the ladder.\n\n### Selecting ladders\n\nIf ladders are used they must be selected to suit the task to be undertaken. In doing this, you should consider the duration of the task, the physical surroundings of where the task is to be undertaken and the prevailing weather conditions.\n\nLadders should have a load rating of at least 120 kg and be manufactured for industrial use.\n\n### Positioning ladders\n\nAny ladder used at a workplace must be set up on a solid and stable surface, and set up so as to prevent the ladder from slipping. Single and extension ladders can be prevented from slipping by:\n\n-   placing ladders at a slope of 4:1, and setting up stepladders in the fully opened position\n-   securing ladders at the top or bottom, or if necessary, at both ends (see Figure 27).\n\nFigure 27: Some effective ways of securing a ladder\n\n![Figure 27 shows some effective ways of securing a ladder.](image.028.png)\n\n### Access or egress\n\nWhere fixed or extension ladders are used for access or egress, you should check that:\n\n-   there is a firm, stable work platform, free from obstructions, to step onto from the ladder\n-   the ladder extends at least one metre above the stepping-off point on the working platform\n-   fall protection is provided at the stepping\\-off point where people access the working platform.\n\nFigure 28: Example of acceptable ladder use\n\n![Figure 28 shows an example of acceptable ladder use.](image.029.jpeg)\n\n### Safe Use of Ladders\n\nWhen a ladder is used, you should check that:\n\n-   the ladder is in good condition—the ladder should be inspected for faults, such as broken rungs, stiles and footing before it is used\n-   damaged ladders are removed from service\n-   the ladder is set up on firm, stable and level ground\n-   the ladder is the correct height for the task to avoid reaching or stretching\n-   the ladder is not too close or too far from the support structure—the distance between the ladder base and the supporting structure should be about one metre for every four metres  \n    of working ladder height (4:1 ratio)\n-   the ladder is secured against displacement (i.e. slipping or sliding) and/or there is another person holding the base of the ladder\n-   the ladder is not placed so that the weight of the ladder and any person using the ladder  \n    is supported by the rungs\n-   all the locking devices on the ladder are secure\n-   materials or tools are not carried while climbing the ladder—use a tool belt or side pouch\n-   only light duty work is undertaken while on the ladder, where three points of contact can  \n    be maintained and tools can be operated safely with one hand\n-   slip resistant base, rungs or steps are provided\n-   slip resistant shoes are worn\n-   ladders are not used without additional appropriate precautions:\n\n-   in access areas or doorways—if necessary, erect a barrier or lock the door shut\n-   on scaffolding or an elevating work platform to get extra height\n-   next to power lines unless the worker is trained and authorised and the appropriate ladder is being used\n-   in very wet or windy conditions\n-   next to traffic areas, unless the working area is barricaded.\n\nFigure 29: A step platform can provide a stable work surface\n\n![Figure 29 shows how a step platform can provide a stable work surface. ](image.030.jpeg)\n\nWhen using ladders, it is not safe to:\n\n-   use metal or metal reinforced ladders when working on live electrical installations\n-   carry out work such as arc welding or oxy cutting\n-   work over other people\n-   allow anyone else to be on the ladder at the same time.\n\nExcept where additional and appropriate fall protection equipment is used in conjunction with the ladder, it is not safe to:\n\n-   use a stepladder near the edge of an open floor, penetration or beside any railing\n-   over-reach (the centre of the torso should be within the ladder stiles throughout the work)\n-   use any power or hand tool requiring two hands to operate, such as concrete cutting saws  \n    and circular saws\n-   use tools that require a high degree of leverage force which, if released, may cause the user  \n    to over\\-balance or fall from the ladder, such as pinch bars\n-   face away from the ladder when going up or down, or when working from it\n-   stand on a rung closer than 900 mm to the top of a single or extension ladder\n\n-   stand higher than the second tread below the top plate of any stepladder (with the exception  \n    of three-rung step ladders).\n\nGuidance on the selection, safe use and care of portable ladders is set out in AS/NZS 1892 Portable ladders series. The manufacturer’s recommendations on safe use should also be followed.\n\nFigure 30: Examples of unsafe ladder use![Examples of unsafe ladder use.](image.031.jpeg)\n\n## 7.2 Fixed ladders\n\nFixed ladders should be installed in accordance with AS 1657 Fixed Platforms, Walkways, Stairways and Ladders—Design, Construction and Installation.\n\nLadder cages in fixed ladders do not stop a fall but simply funnel a fall and, in some cases, more injuries can occur from striking the protective backguards on the way down. The cages may also hinder rescues. Therefore, fixed ladders with angles exceeding 75 degrees to the horizontal  \nshould be fitted with a permanent or temporary fall\\-arrest system (anchorage lines or rails).\n\nThe angle of slope should not be less than 70 degrees to the horizontal and not greater than  \n75 degrees to the horizontal. In no case should the ladder overhang the person climbing  \nthe ladder. If the angle is more than 75 degrees, a safe system of work to prevent falls should be provided such as a permanent fall\\-arrest system or a full body harness with double arm lanyard.\n\nA specifically designed rescue procedure should be developed for use in ladder cage situations. Training in rescue procedures should occur before using the fixed ladder.\n\nFigure 31: Example of a fixed ladder fitted with a ladder cage\n\n![Example of a fixed ladder fitted with a ladder cage.](image.032.jpeg)\n\n## 7.3 Ladder maintenance\n\nLadders should be regularly inspected by a competent person in accordance with the manufacturer’s recommendations. Ladders with any of the following faults must be replaced  \nor repaired:\n\n-   fibreglass stiles cracked, chipped or severely faded with fibres exposed\n-   timber stiles warped, splintered, cracked or bruised\n-   metal stiles twisted, bent, kinked, crushed or with cracked welds or damaged feet\n-   rungs, steps, treads or top plates that are missing, worn, damaged or loose\n-   tie rods missing, broken or loose\n-   ropes, braces, or brackets that are missing, broken or worn\n-   timber members that are covered with opaque paint or other treatment that could disguise faults in the timber\n-   missing, loose, bent or worn fasteners, i.e. rivets, bolts and pins\n-   worn or damaged feet, including non\\-slip material.\n\n#   \n8. ADMINISTRATIVE CONTROLS\n\nAdministrative controls may be used to support other control measures and may include ‘no go’ areas, permit systems, the sequencing of work and safe work procedures. Using administrative controls exclusively to minimise the risk of falls is only appropriate when it is not reasonably practicable to use a higher order control.\n\nFigure 32: Example of a sign for a ‘no go’ area\n\n![Figure 32 shows an example of a sign for a ‘no go’ area.](image.033.png)\n\n## ‘No go’ areas\n\n’No go’ areas can be an effective method of making sure people are not exposed to hazards.  \nThey require clear signs warning people not to access the hazardous area. They can be used  \nto highlight the risks of entry to an area where there is an unguarded hazard, or to areas where work is being undertaken overhead and there is a risk of falling objects.\n\nRelevant information and instruction should be provided about ‘no go’ areas with adequate supervision to ensure that no unauthorised worker enters the ‘no go’ area.\n\nBarriers should be used in conjunction with signs to cordon-off areas where there is a risk  \nof falling or being hit by falling objects. They should be highly visible and securely fixed to  \nprevent displacement.\n\n### Permit systems\n\nPermit systems allow only competent persons trained in the use of relevant control measures  \nto work in an area where there is a hazard. Examples include:\n\n-   tagging all access points to a scaffold to restrict unauthorised access during erection  \n    and dismantling, with ‘only licensed scaffolders permitted on an incomplete scaffold’\n-   requiring permits for access to areas where travel restraint systems or fall\\-arrest systems are  \n    to be used.\n\n### Organising and sequencing of work\n\nWork should be organised so that people do not interfere with other workers or increase the risk  \nto themselves or others. For example, you can sequence jobs so that different trades are not working above or below each other at the same time. Plan the work so tasks are not performed  \nfor extended periods from a ladder, or so that work at height is minimised in extremely hot  \nor cold weather.\n\n  \n\nSafe work procedures\n\nAn administrative control may be as simple as a safe work procedure that describes the steps involved in safely undertaking a task. It may also include any particular training, instruction and the level of supervision required. For example, a safe work procedure to reduce the risk of falls when entering or exiting vehicles may include instructing drivers to not jump down from the cab and always maintain three points of contact when climbing into or out of the cab (see Figure 33).\n\nFigure 33: Diagrams showing the correct procedure for climbing in and out of trucks\n\n![Figure 33 shows diagrams with the correct procedure for climbing in and out of trucks.](image.034.jpeg)\n\nIf relying on administrative controls, it may be necessary to provide a high level of supervision  \nto ensure that the safe work procedure is being adhered to.\n\n#   \n9\\. EMERGENCY PROCEDURES FOR FALLS\n\nWhenever there are risks from working at height, appropriate emergency procedures and facilities, including first aid, must be established and provided. Typical injuries from falls can include unconsciousness and occluded airway, impalement, serious head or abdominal injuries and fractures.\n\nA person using a fall\\-arrest system could suffer suspension intolerance as a result of a fall.  \nThe WHS Regulations contain a specific provision to address the need for emergency and  \nrescue procedures for such situations.\n\nRegulation 80: A person conducting a business or undertaking who implements a fall\\-arrest system as a measure to control risk must establish emergency and rescue procedures.\n\nThe procedures must be tested so that they are effective. Workers must be provided with suitable and adequate information, instruction and training in relation to the emergency procedures.\n\n## 9.1 Emergency procedures\n\nIn developing emergency procedures, the different types of emergency and rescue scenarios that might arise should be considered. Information from the risk assessment will help in this task.\n\nRegulation 42: You must ensure that workers have access to first aid equipment and facilities  \nfor the administration of first aid. You must also ensure that workers are trained to administer  \nfirst aid or that workers have access to persons who are trained in first aid.\n\nFurther guidance is available in the First Aid in the Workplace Code of Practice \\[under development\\].\n\nThe emergency procedures for falls may be incorporated into the emergency plan required for the workplace under the WHS Regulations.\n\nWhen establishing emergency procedures, you should take into account the following:\n\n| Relevant considerations                                         | Questions                                                                                                                                                                                                                                                                                                                                                                                                                             |\n| --------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n| Location of the work area                                       | Is the work at height being undertaken in a remote or isolated place?

The lower legs’ capacity to store large amounts of blood reduces the return of blood to the heart, slowing the heart rate, which can cause the person to faint. This may lead to renal failure and eventually death, depending on a person’s susceptibility. This condition may be worsened by heat and dehydration.\n\nThe quick rescue of a person suspended in a full body harness, as soon as is possible, is vital.  \nFor this reason, workers should be capable of conducting a rescue of a fallen worker and be familiar with onsite rescue equipment and procedures.\n\nWorkers and emergency response workers must be trained in the rescue procedures and be able to recognise the risks of suspension intolerance and act quickly in the rescue of a person.\n\n### Preventing suspension intolerance\n\nTo prevent suspension intolerance occurring as a result of an arrested fall, you should ensure that:\n\n-   workers never work alone when using a harness as fall protection\n-   workers use a harness, which allows legs to be kept horizontal\n-   the time a worker spends in suspension after a fall is limited to less than five minutes. When  \n    a suspension is longer than five minutes, foothold straps or a way of placing weight on the  \n    legs should be provided.\n-   workers are trained to do the following when they are hanging in their harness after a fall:\n\n-   move their legs in the harness and push against any footholds, where these movements are possible. In some instances, the harness design and/or any injuries received may prevent this movement\n-   move their legs as high as possible and the head as horizontal as possible, where these movements are possible.\n\n### Training for rescues\n\nThe training for rescuing workers who have fallen should address the following factors:\n\n-   the rescue process should start immediately\n-   training frequency should take into account the worker’s competence and their ability to retain competence through regular exposure to the equipment and skills needed to perform a rescue\n-   workers should not put themselves at risk during a rescue.\n\n#   \n10. DESIGN OF PLANT AND STRUCTURES\n\n## 10.1 Design considerations\n\nConsideration of the potential risk of falls early when designing plant or structures can result in the elimination of such risks. Where elimination is not possible, one way to minimise risks at the design stage is to integrate fall prevention systems into the design.\n\nSafety considerations at the design stage should include:\n\n-   safe entry to and exit from any work area\n-   designing permanent guard rails or other forms of edge protection (for example, parapet walls) for permanent fall prevention on roofs\n-   future maintenance requirements, especially in relation to sloping building exteriors and windows, to ensure maintenance can be carried out safely\n-   specifying the strength of roof members and other points to which guard rail, or anchor points for work positioning systems will be fixed\n-   safer building design generally, with, for example:\n    -   low-level mounting of roof vents\n    -   the location of air conditioning units and other roof-mounted plant, such as satellite dishes, away from edges\n    -   the location of air conditioning and similar plant at ground level\n    -   the specification of non-fragile material for the roof\n    -   the use of permanent safety mesh\n    -   safer gutters, for example, installing large volume gutters and down pipes to minimise the need to access the roof for cleaning, locating the gutters at ground level or away from edges, or the removal of gutters altogether, with a smooth transition from the roof to the walls with the gutters at ground level.\n-   specific safety requirements for particular workers doing subsequent installation, maintenance or repair work. These groups include:\n    -   people installing and maintaining antennae and satellite dishes\n    -   contractors servicing air conditioning equipment on the roof\n    -   window and gutter cleaners and repairers\n\n-   designing the pre-fabrication of structures on the ground before they are lifted into position.\n\n## 10.2 Plant\n\nSafety considerations at the design stage could include:\n\n-   providing adequate steps and hand rails on vehicles (see Figure 34)\n-   incorporating a fall prevention system in silos and overhead conveyors\n-   ensuring workers who will be maintaining or cleaning the plant are able to do so safely\n-   considering the safety of passengers.\n\nSection 21 Designers must provide information to each person who is provided with the design that includes information on the purpose for which the plant was designed and how the use the plant safely.\n\nFigure 34 Dump trucks\n\n![Figure 34 shows a picture of a dump truck.](image.035.jpeg)\n\n## 10.3 Buildings and structures\n\nDesigners or constructors of buildings or structures must ensure, so far as is reasonably practicable, that workers involved with the construction, use or subsequent maintenance are not exposed to the risks associated with work at height. Therefore, at the design and planning stage,  \nit is important to consider providing fall prevention systems as part of the building or structure.\n\nAs it is unlikely that all design work on larger projects will be carried out by one designer, consultation, co-operation and co-ordination should occur between the builder and other designers to ensure the safe interaction of the different design aspects.\n\nWhen risks remain in the design work, information must be included with the design to alert others to the risks. Providing information about safety issues is a key component to ensure proper, adequate and suitable design and installation.\n\nThe design and planning for the construction stage should include:\n\n-   reducing the risk for those working at heights, such as the installation of guard rails to perimeter structural members prior to erection\n-   reducing the time spent working at heights by pre-fabricating modules on the ground, before lifting them into position\n-   sequencing of the work to be performed at heights\n-   the location and condition of access roads, for example to enable a crane to place building materials in the most appropriate and accessible location, rather than the materials being moved manually\n-   preparation of the ground or floor below the work area. It should be compacted and level  \n    to support plant or equipment, such as cranes and scissor lifts\n-   identification of underground services including drainage, for example for the safe setting  \n    up of cranes\n-   provision of permanent safety mesh.\n\n### Planning for building maintenance\n\nDuring the planning stage, consideration should also be given to the methods by which maintenance, repairs or cleaning will be undertaken on a building or structure, for example:\n\n-   designing window cleaning bays or gangways integrated into the structural frame\n-   designing permanent anchorage and hoisting points into structures where maintenance needs to be undertaken at height.\n\n### Planning the site layout\n\nWhen planning the site layout, the following factors should be considered:\n\n-   the preparation of firm, level surfaces below work areas for the support of plant and equipment, such as scissor lifts or mobile scaffolds\n-   the site and condition of access roads to enable plant to place material in and pick it up from the most favourable positions, thereby reducing, for example, the need for manual handling at height\n-   safe access to and egress from work areas and amenities, including the provision and placement of stairways, ladders, catwalks, guardrails and barriers\n-   the need for adequate means of escape and rescue in the event of an emergency.\n\n#   \nAPPENDIX A – TERMS USED IN FALL CONTROL MEASURES\n\nAnchorage: means a secure point for attaching a lanyard, lifeline or other component of a travel restraint system or fall\\-arrest system.

Providing information about safety issues is a key component to ensure proper, adequate and suitable design and installation.\n\nThe design and planning for the construction stage should include:\n\n-   reducing the risk for those working at heights, such as the installation of guard rails to perimeter structural members prior to erection\n-   reducing the time spent working at heights by pre-fabricating modules on the ground, before lifting them into position\n-   sequencing of the work to be performed at heights\n-   the location and condition of access roads, for example to enable a crane to place building materials in the most appropriate and accessible location, rather than the materials being moved manually\n-   preparation of the ground or floor below the work area.
