Judgment (9 paragraphs)
Judgment 1Cement Australia Pty Limited (CAPL) has pleaded guilty to an offence under s 10(2) of the Occupational Health and Safety Act 2000 (the Act). The offence and accompanying particulars are set out in an amended application for order which was filed on 29 January 2013. 2Cement Australia (Kandos) Pty Limited (CA Kandos) was charged under s 8(2) and in the alternative under s 10(2) of the Act. The charge in the alternative was not pursued by the prosecution and an application for its withdrawal was granted. With regard to the remaining charge under s 8(2), the prosecution informed the Court that it could not be satisfied beyond reasonable doubt that the prosecution could prove one of the legal elements of the offence, namely, that Colin David Fuller was a person "other than an employee" of CA Kandos whom CA Kandos had failed to ensure was not exposed to risks to his health and safety. An application was made by the prosecution under s 30 of the Act, which was not opposed by CA Kandos, that the Court could be satisfied in the alternative that CA Kandos had contravened s 8(1) of the Act. Section 30 provides: If in proceedings against a person for an offence against a provision of section 8 or 9 the court is not satisfied that the person contravened that provision but is satisfied that the act or omission concerned constituted a contravention of another provision of section 8 or 9, the court may convict the person of an offence against that other provision. 3It was an agreed fact between the parties that CA Kandos was the employer of Mr Fuller at the date of the incident, the subject of the alleged contravention. Following the tender of evidence, I reviewed the material relied upon in relation to this matter and I advised the parties that I was satisfied, in accordance with the requirements under s 30 of the Act, that the acts or omissions alleged against CA Kandos in the s 8(2) charge constituted a contravention of s 8(1) of the Act. Following that advice, CA Kandos pleaded guilty to an offence under s 8(1) of the Act. The plea of guilty encompassed the "acts and omissions" alleged against CA Kandos in the s 8(2) charge. 4The charges against both defendants concern the same underlying factual circumstances which occurred prior to and at the time of the incident. The relevant facts may be drawn from the Agreed Statement of Facts, a document tendered by the prosecutor in both sets of sentence proceedings. 5Both defendants are part of a trading group, the Cement Australia Group (the CA Group). The group is engaged in the mining, processing, manufacturing, sale, supply and distribution of cementitious products, including limestone, clay and raw materials through its various subsidiaries. CA Kandos is the owner of premises at Kandos, at which is located a cement processing plant (the plant) also owned by CA Kandos. At about 10.20pm on 13 September 2009, Mr Fuller suffered fatal injuries when he was crushed between two hydraulic rams that constituted a component part of the plant at the premises, known as the C2 Reciprocating feeder. 6CAPL is the manager of CA Kandos pursuant to a Management Agreement. Through its role as manager of CA Kandos, CAPL had, to a relevant extent, control of the plant and equipment at the premises. This control was exercised through its: a. authority to authorise and approve capital expenditure in relation to plant and equipment at the Site; b. development of the Cement Australia Group safety management system applicable at the Site; c. the undertaking or engagement of others to undertake audits of the plant and equipment at the Site. 7As at 13 September 2009, CA Kandos employed about 80 employees at the premises. Mr Fuller had been working at the premises while employed by another business entity, Skilled Engineering, from about 7 February 2008. He commenced full-time employment with CA Kandos as a Day Process Operator at the premises on 4 August 2008. Sam Vellenoweth was the Operations Manager of the processing plant. Brett Morgan was the Production Performance Manager. Phillip Jackson and Jeffrey Rogers were each employed by CA Kandos at the premises as Central Control Operators (CCOs). Their role was to monitor the plant operations from a Central Control Office at the premises via various monitoring equipment which included videos and computer screens. Mr Jackson was on duty on the evening of 13 September 2009 and was responsible for part of the plant known as the Raw Materials Preparation Area. Mr Rogers was also on duty at that time, but was primarily responsible for part of the plant known as the Production Area. Grant Keech was employed by CA Kandos as a Central Control Assistant (CCA) at the premises. On the evening of 13 September 2009, Mr Fuller was on duty performing the role of a CCA, principally in respect of the Raw Materials Preparation Area. Mr Keech was also on duty as a CCA, but was performing those duties primarily in respect of the Production Area. 8The role of a CCA contemplated assisting the CCOs to maintain the safe and efficient operation of the plant. CCAs worked in three main sections of the plant, namely, the: a. Raw Materials Section; b. Kiln Section; c. Cement Production Section. 9The duties of a CCA included: a. performing pre-start checks on plant and equipment; b. monitoring of plant, equipment and systems; c. monitoring of product quality; d. performing front line maintenance to plant, equipment and systems; e. performing house keeping duties. 10Details of the plant, including a description of its component parts and its operation, are set out in the Agreed Facts, extracted below: The Raw materials Preparation Area included an area called the Stone Tunnels. This was located in the North East corner of the site. The Stone Tunnels contained plant and equipment, in particular two reciprocating feeder and conveyor belt systems, known as conveyor belt two ("C2") and conveyor belt three ("C3"), ""the CS & C3 Reciprocating feeders"). The length of each of the C2 & C3 Reciprocating feeders was approximately 60 metres. At each side of the conveyors were passageways approximately 1.5 metres wide. The height of the Stone tunnels from the floor to the ceiling was approximately 2.3 metres and each tunnel had an approximate width of 4.5 metres. Electric lights were installed at intervals along the tunnel. However, the lighting levels in the Stone tunnels were poor. The C2 & C3 Reciprocating feeders were part of the process whereby raw materials, predominantly crushed limestone, were transported from the crusher to the production area of the plant. The C2 & C3 Reciprocating feeders are fixed items of plant made up of hoppers, feeder frames and hydraulic rams. Each feeder was attached to the ceiling of the tunnels. The hopper or chute is a shaft that channels the limestone onto the conveyor. The C2 & C3 Reciprocating feeders also had banks of hydraulically operated feeders which transported the limestone from the hoppers above onto the conveyor system. The feeders were moved by sets of hydraulic rams. The hydraulic ram system consisted of several plant components including feeder frames (also known as retractable hoppers), which were bolted to a plate that is attached to a plate by pivot pin. The feeder frames comprised of a steel frame that had a mesh base. The purpose of this feeder frame is to act as a "shaker" that slides back and forth producing friction in the hopper to cause the limestone to fall down into the conveyor below. Each conveyor was divided into three banks, with five stone feeders above each bank. The design of the banks meant that at points along the C2 & C3 Reciprocating feeders the rear of the hydraulic rams of one set of feeder frames was horizontally opposed to the rear of another set of feeder frames. The hydraulic rams were approximately 125 mm in diameter laying horizontally in line with the conveyor at a height of approximately 1.5 m and facing inwards towards each other. Each ram was mounted at the outer end to a substantial welded lug on upright fixed girders that ran from the floor to the ceiling. The inner ends, i.e. the pistons of each ram, were mounted to separate heavy steel frames that sat above and across the conveyor. Directly opposite on the far side of the conveyor was an identical set of opposed hydraulic rams connected in the same way to the two steel frames. Each steel frame of the feeders was supported on a solid steel wheels that sat on the metal work at the sides of the conveyor, similar to a flattened rail car sitting on tracks. The steel wheels allowed fore and aft movement of the steel frames of the feeders as the hydraulic rams advanced and retracted. Between the two steel frames of the feeders, at a height of about 1.5 m was a parallel gap of approximately 120 mm. The frame at either side of the gap was made of steel which lay across the width of the conveyor, extending beyond the framework of the conveyor at each side by approximately 250 mm. During the operation of the C2 conveyor the hydraulic rams moved the frames of the feeders towards and apart from each other. Each stroke of the rams took approximately 2 seconds and moved the frames approximately 200 mm. At the end of each stroke, there was a pause of approximate (sic) 15 seconds before the ram moved the frame in the opposite direction. The feeders did not move together and apart at the same time. When one bank moved, the other remained stationary. This produced a pattern of movement that resulted in various gaps between the two feeders of approximately 445 mm when fully opened and 85 mm at the closest position. The Australian Standard - Safety of Machinery Part 1803 & Part 1101 outlines the minimum distance for crushing zones where an arm is expected should be 120 millimetres, and where a body is expected, it should be 500 millimetres. As at 13 September 2009, the C2 Reciprocating feeder and conveyor system was not fully guarded along its length. It did have some guarding in place at some of the potential nip or crush points, for example, there was guarding on the wheels of the feeder frames and on the head and tail drums of the conveyor belts. However, there was an absence of guarding along the C2 Reciprocating feeder and conveyor system at the banks of feeders at the point where the rear of hydraulic rams of one set of feeder frames was horizontally opposed to the rear of another set of feeder frames. The Australian Standard - Conveyors - Safety requirements AS1755-2000 requires that guards be installed to prevent access to danger zones in or around a conveyor system in which a person is subject to a risk to health or safety. Below the frame of the conveyor, on each side, there was a lanyard cable that ran the length of the conveyor at a height of approximately 1100 mm. Its purpose was to electrically isolate the C2 feeder and conveyor when it was pulled. It was designed and functioned to immediately stop all associated machinery including the conveyor belt, the feeder, and the hydraulic rams. Directly below the lanyard, running along the frame of the conveyor at a height of approximately 400 mm above the ground was a hydraulic line, which consisted of a steel pipe about 25 mm in diameter. In or about 2007, CA Kandos put forward a capital expenditure request for the upgrade of the C2 Reciprocating feeder and conveyor system. The capital expenditure request was considered and approved by the CA Group Chief Financial Officer, Greg Blackford and the CA Group Chief Executive Officer, Mr Leon in mid 2008. The C2 Reciprocating feeder and conveyor systems were re-built in mid 2008. The specifications prepared by the Cement Australia Group for the work to be undertaken on the C2 Reciprocating feeders did not specify the installation of fixed guarding which complied with the Australian Standards on guarding at all crush zones and danger zones and in particular between the hydraulic rams of the feeder frames. However, the 'Invitation to Tender' document prepared by the CA Group for the re-build of the C2 Reciprocating feeders under the heading "Safety Standards states that "Relevant Australian Standards and codes of practice shall be complied with". In failing to install a guard at the crushing zone of the C2 conveyor where the hydraulic rams moved the frames of the feeders towards and apart from each other, the defendants failed to comply with the requirements of Australian Standard - Safety of Machinery Part 1803 & Part 1101 and Australian Standard - Conveyors - Safety requirements AS1755-2000. 11Details of the incident which resulted in the death of Mr Fuller are also set out in the Agreed Facts, extracted below: Colin Fuller commenced work at approximately 7:30 pm on 13 September 2009. He was due to undertake an afternoon shift that commenced at 8.00 pm. As at 13 September 2009, there was no direct supervisor on Site to whom Mr Fuller reported during the afternoon and night shifts on weekends. On 13 September 2009, at approximately 9:50 pm Phillip Jackson, CCO noticed on monitoring equipment located in the Central Control Room that the normal grade hopper level was low on the C3 Reciprocating Feeder. In the Central Control room there was a silent visual alarm system to draw the attention of the Central Control Operators that there would be a feeder not feeding correctly. This alarm did not specifically indicate the cause of the problem or whether it was caused by a blockage in the system. Accordingly, a visual inspection was required to identify the specific problem. Part of the role of a CCA was to undertake such a visual inspection to identify the cause of the problem and, where safe and appropriate, to rectify the problem. Shortly after 9:50 pm on 13 September 2009, Mr Jackson contacted Mr Fuller by two-way radio. Up to that time Mr Fuller had been performing his rostered duties, and checking on the raw mill throats. Mr Jackson then instructed Mr Fuller to do an inspection of the feed line on the C3 Reciprocating Feeder. Mr Fuller subsequently attended at the C3 Reciprocating Feeder in the Stone Tunnels and located feeders where a shear pin had broken. Mr Fuller was working alone whilst undertaking the task. Mr Fuller then radioed the Central Control Room to deselect the C3 Reciprocating Feeder so he could safely replace the broken shear pin. Mr Jackson deselected the C3 Reciprocating Feeder at approximately 9.55 pm then notified Mr Fuller who then commenced work replacing the broken shear pin. After a short period of time Mr Fuller then radioed Mr Jackson informing Mr Jackson that the problem had been rectified. The C3 Reciprocating Feeder was put back into service at approximately 10:09 pm. Mr Jackson then radioed Mr Fuller and informed Mr Fuller that numerous hoppers in the C2 Reciprocating Feeder in the Stone Tunnels were not feeding. Mr Jackson then directed Mr Fuller to undertake a visual inspection of the feed lines of the C2 Reciprocating Feeder in the Stone Tunnels to identify the problem. Mr Fuller was working alone whilst undertaking this task. There was no further communication between Mr Fuller and Mr Jackson. At approximately 10:12 pm Mr Jackson saw that the system was flashing indicating that lanyard one (1) of the C2 Reciprocating Feeder in the Stone Tunnels had been isolated. Ordinarily, the isolation of a lanyard would be followed by radio communication from the CCA who tripped the lanyard advising the Central Control Operator of the reason for the stoppage. However, the Central Control room did not receive any communication from Mr Fuller or any other CCA regarding the reason for the stoppage. After waiting a few minutes Mr Jackson attempted to radio Mr Fuller two (2) or three (3) times to ask if Mr Fuller had tripped the lanyard. However, Mr Jackson was unsuccessful in his attempts to contact Mr Fuller. At approximately 10.42 pm the Central Control Operator gave the system a reset. The operator turned off the C3 Reciprocating Feeder. At approximately 10.43 pm the C2 Reciprocating Feeder was selected not to run by the Central Control Operator. The C3 Reciprocating Feeder was also selected not to run by the Central Control Operator. At approximately 10.50 pm the C2 Reciprocating Feeder was isolated. At approximately 10.50 pm the Central Control Operator gave the system a reset. The C2 conveyor belt was still isolated at the whole current isolator (WCI). At approximately 10.50 pm the Central Control Operator attempted to start the C2 Reciprocating Feeder to prove isolation. At approximately 10.51 pm the Central Control Operator acknowledged the whole current isolator (WCI) alarm. Mr Jackson then decided to go down and physically check on Mr Fuller and the tripped lanyard. Mr Jackson then proceeded to the Stone Tunnels and entered the tunnels. Mr Jackson then proceeded down the length of the C2 conveyor and discovered Mr Fuller crushed between two hydraulic rams. Mr Fuller was crushed at the point of the middle of his chest and back with his arm reaching up into the front bin. Mr Jackson checked Mr Fuller's pulse and found he didn't have one, and immediately radioed for emergency services. An ambulance arrived a short time after and Mr Fuller was pronounced dead at the scene. Mr Fuller was subsequently removed by emergency service personnel from the C2 Feeder. An inspection of the site shortly after the Incident discovered a hammer just under Mr Fuller's right hand along with a large piece of cementitious material under the chute next to Mr Fuller. It is possible that while inspecting the C2 Feeder and conveyors equipment, Mr Fuller may have identified that this large piece of cementitious material was causing a blockage in a hopper which fed the C2 conveyor. The cementitious material appears to have been causing a blockage of the Feeder. The hammer was located in the vicinity of the cementitious blockage in the feeder. This hammer may have been used by Mr Fuller to attempt to strike the cementitious material to free up the blockage. It also appears that Mr Fuller may have decided to attempt to remove the blockage manually using the hammer while the plant was still operating and was not isolated from its energy source. This was contrary to the practice and procedures at the site at the time and with respect to which Mr Fuller had been trained and instructed, which required the plant to be isolated and locked out prior to any person accessing the plant. 77. It is not known exactly how Mr Fuller came to be in a position where his body was between the two hydraulic rams. It is possible that, in order to access the area where the large piece of cementitious which was causing a blockage was located, Mr Fuller may have climbed onto the hydraulic lines that ran along the side of the conveyor system. This would have required him to manoeuvre himself over the safety lanyard. Blockages were common occurrences on the C2 and C3 Feeders and Conveyors. The blockages were usually caused by wet clay that settled down into the feeder, which then built up and formed a blockage. Typically, blockages were left in situ until the C2 and C3 conveyor belts and hydraulics were isolated and dozers were brought into the stone sheds located above the feeders to dig and break up the blockage out from above. It is not apparent as to why Mr Fuller would attempt to clear a blockage on the C2 feeder without isolating the machinery first as it was not in accordance with the existing procedure at the Kandos Plant. Mr Edward Norris, a Fitter employed by CA Kandos, stated that it was a common practice to stand on the hydraulic lines of the C2 Feeder to look at the feeders and check them while the C2 Reciprocating Feeders and conveyor systems were still operating. He believed that was what Mr Fuller was doing at the time of the incident. Mr Norris had last worked in the stone tunnels approximately 2 years preceding this incident, but had not worked in there subsequently. The stone tunnel re-build was in mid 2008. Mr Morgan, a Production Performance Manager employed by CA Kandos, stated that approximately 2.5 years prior to the Incident he had identified and reported the specific risk of a 'potential pinch point' for a hand or arm where the feeders move backwards and forwards. Mr Morgan had noted that there 'is a small area that closes up and leaves a small gap'. He also stated that he verbally reported the issue to the Production Manager approximately 2.5 years prior to the Incident. In response Mr Morgan put yellow safety tape around the feeders and informed the teams working in the area of this hazard. However, no guarding was installed by CA Kandos or CAPL as the areas on the C2 Reciprocating feeder and conveyor system where the risk had been identified.
