8. On 4 November 2003 Inspector Jones attended the site to carry out a compliance inspection following the issue of the Improvement Notices.
9. On this date Inspector Jones introduced himself to Daniel Bacic, site manager, employed by Walker Group and an inspection was conducted.
10. During the site inspection, Inspector Jones observed the following:
o An industrial warehouse under construction of approximately 15,000 square metres in size.
o Various construction workers carrying out various construction activities.
o A scaffold stair access to a roof known as the Main Office Roof.
o Two persons (Cornish and Fleming) working near the edge of the Main Office Roof which was approximately 6 to 7 metres in height from the ground
o Both persons were wearing a harness.
o Both persons were not attached to an anchorage point.
o Two persons (Paziuk and Kroehnert) working in close proximity to the edge of a roof known as the Transport Office Roof approximately 3 metres in height from the ground.
o Both persons were wearing a harness.

o An access ladder to the Transport Office Roof.
o Three persons working from an Elevated Work Platform ("EWP"). The EWP was extended to approximately 8 metres in height.
o One person alighted from the EWP so as to gain access to the Main Roof.
11. On 4 November 2003, Inspector Jones took photographs of the site. A copy of 5 photographs taken by Inspector Jones on this date are attached and marked "A".
12. At the time of Inspector Jones' visit to the site, Paziuk and Kroehnert were fitting upstands and trays for the air-conditioning fans and were working approximately 2.5 metres from the edge of the Transport Office roof of the industrial complex.
13. Both Paziuk and Kroehnert had on harnesses and lanyards whilst working; however, they were not attached to an anchorage point on the roof. The parapet wall located on the edge of the roof adjacent to where Paziuk and Kroehnert were working was between 0.5 metres to 1.2 metres in height.
14. Paziuk and Kroehnert used a ladder to access the Transport Office roof which was tied off to prevent it moving or slipping. They did not use a fall prevention system whilst accessing the Transport Office roof. The Transport Office roof was approximately 3 metres high.
15. Paziuk and Kroehnert had been instructed on the basis of JB Metal's Job Safety Analysis that their harnesses were to be attached to an anchorage point whilst working within 1.8 metres of the edge of the roof.
16. At the time of the Inspector's visit to the site, Fleming and Cornish were installing flashings on a parapet wall situated on the edge of the Main Office roof at a height of approximately 6 to 7 metres. The parapet wall located on the edge of the roof where Fleming and Cornish were working varied in height from 0.44 metres to 1 metre.
17. Both Fleming and Cornish were wearing harnesses; however they were not attached to an anchorage point on the roof and no anchorage points had been installed on the roof.
18. Kroehnert had performed a risk assessment prior to Paziuk, Cornish Fleming and himself performing the work. He did not comply with the JB Metal Job Safety Analysis which required the use of fall arrestors when working in areas where you could fall more than 1.8 metres as he did not think it was necessary.
19. A representative of Walker Group instructed all the roof workers prior to the commencement of work that fall prevention systems had to be installed.
20. According to Fleming and Cornish, they had not been observed by any representatives of Walker Group working on the roof edge without being attached to a safety line prior to 4 November 2003.
21. Following the inspection Inspector Jones issued a Prohibition Notice to Garry Denson to prevent work continuing on the main office roof and warehouse roof until a safe system of work was provided for working at heights.
System of work
22. Prior to the roofing work being carried out, Daniel Bacic, Walker Group's site manager accessed the Main Office roof to determine what work was required to be performed.
23. Walker Group required all subcontractors to provide them with copies of their safe work method statements prior to commencing work.
24. A copy of the General Conditions of Contract and Scope of Subcontract Works between Walker Group and JB Metal is attached and marked "B".
25. JB Metal provided Walker Group with a subcontractor safety pack which included a Safe Work Method Statement ("SWMS") for the task of fitting roof accessories. The SWMS included the following instructions:
· All personnel to be trained in correct use of personal protective equipment.
· Anchor points must be in place.
· Ensure anchor points are inspected prior to use.
· Ensure harnesses connected to plant is worn.
· Fall protection system must be used.
· Harnesses and adjustable lanyard rope/inertia reel must be working at all times.
26. A copy of the Job Safety Analysis was kept in the site office for JB Metal's employees and the Walker Group to view.
27. JB Metal did not provide anchorage points on the roof of the industrial complex for its employees to attach their lanyards to whilst working at heights.
28. The Walker Group Project Specific Safety and Injury Management Plan for the site (revision 1, last edited on 22 October 2003) provides that Walker Group will conduct regular inspections of the work areas to ensure uncontrolled hazards are eliminated or controlled. During the inspection the supervisor is to observe as a minimum, the status of company activities in relation to potential hazards including fall potential.
29. Walker Group did not identify that anchorage points had not been provided for persons to attach harnesses and lanyards to whilst working at heights on the roof of the industrial complex on 4 November 2003.
30. The Code of Practice " Safe work on roofs - Part 1 Commercial and industrial buildings" provides in paragraph 3.1:
"Provision should be made to prevent persons falling if work is to be carried out within two metres of any edge on a new or existing roof from which any person could fall more than two metres or more."
Events following the inspection
31. In accordance with the Prohibition Notice issued, JB Metal prevented access to the roof following Inspector Jones' inspection on 4 November 2003.
32. JB Metal enrolled 8 employees in a safety line system course with CompBase Training Services Pty Ltd. The supervisors employed by JB Metal have completed this course.
33. A revised Sub-Contractor Safety Pack including Safe Work Method Statements was produced by JB Metal on 9 November 2003. The Safe Work Method Statement for the task of fitting roof accessories included the following instructions:
"Fall protection must be used. An approved handrail system will be in place on the active work platform physically preventing roof workers from being within 3 metres of roof edge. For employees working within 3 metres from the edge shall (sic) be protected by the use of an approved individual fall arrest system in compliance with AS 1891 & BS5062 which shall be constantly re-anchored to eliminating (sic) risk of a pendulum effect occurring in the case of an arrested fall. Anchor points must be in place and installed by qualified persons only. Ensure anchorage points are inspected prior to use. Roof workers not within this 3 metre perimeter will be protected by the presence of safety mesh…"
34. In February 2004 Inspector Jones was provided with a copy of the Walker Group Occupational Health and Safety Management System Manual ("Manual") issued in February 2004. The manual provides for weekly site safety inspections to be conducted. The items on the checklist for the inspection include work conducted at heights greater than 1.8 metres, harnesses and cherry pickers.
35. The Manual details the site supervisor's responsibilities which include:
"Ensure contractors comply with scope of works and safety procedures as documented in their Work Method Statement (WMS) in compliance with section 227 C/D of the NSW OH&S Regulations 2001 ."
36. The Manual provides for the compliance and assessment of contractors' safe work practices and requires that:
"Contractors will undergo regular assessment to ensure they comply with their identified Work Method Statement and Walker Group Constructions Pty Limited site safety procedures in compliance with the OHS Act 2000 and OHS Regulation 2001 ."
37. The Site Occupational Health & Safety Audit checklist which forms part of the Manual provides for checks to be made of harness/lanyards, static line/arrester and ladder access where work is performed at heights on a roof. The checklist indicates that the area is to be barricaded off and signs used, a temporary hand rail is to be fitted and safety mesh laid prior to works commencing.
7 Mr P.M. Skinner, of counsel, appeared for the prosecution in the hearing as to penalty. An Agreed Statement of Facts was relied upon. The prosecution also tendered a number of photographs of the site taken on 4 November 2003 and a copy of the general conditions imposed on the sub-contractor.
