[15] Kingstone did not report the accident to WorkCover. WorkCover first learned about the incident on or about 9 September 2003 when contacted by Mrs Coulter.
[16] On 11 September 2003, Inspector Page issued Kingstone with Improvement Notice 7-36576 concerning the erection of a perimeter fence and site signage. Fencing work was underway during the inspector's visit. Perimeter fencing of the site was completed by 1pm on 12 September 2003.
Investigation
[17] At approximately 10:20 am on 1 December 2003 the prosecutor attended the site in response to a verbal notification of the incident. The Prosecutor observed the following:
[17.1] A two storey brick residential house with no signage, a letterbox at the front of the adjoining property had the number 21 on it and the adjacent property had a letterbox with the number 17 on it.
[17.2] The Prosecutor walked up the concrete driveway and turned onto the adjoining path, to the south western/rear entry door and alcove of Lot 21. no 19.
[17.3] The entry to the rear alcove consisted of three concrete steps up to a concrete veranda, surrounded on two sides by a black aluminium handrail 1,030 mm high (1.03 metres).
[17.4] The entry alcove walls were sheeted with textured fibre cement sheeting with various timber beadings.
[17.5] The entry door was white with a frosted decorative triangular glass panel.
[17.6] The ceiling of the alcove was lined with flat cement fibre sheeting approximately 1,300 x 950 mm (1.3 m x 0.95 m).
[17.7] The distance from the ceiling sheeting to the ground was approximately 2,730mm (2.73 metres).
[18] As at the date of the incident, Kingstone employed Siedlecki as site supervisor. Siedlecki commenced employment with Kingstone in the position of site supervisor in June 2003. Siedlecki had prior occupational health and safety training from previous employers. Siedlecki, in the course of his ordinary employment, attended the site approximately every second day between Monday and Friday. Siedlecki was also the nominated site supervisor for approximately 15 other Kingstone building and construction sites located between Rouse Hill and Nelson Bay. Mr Willis supervised Siedlecki and occasionally visited the site. General tool box talks with Siedlecki and the work crew took place at Kingstone's office once a month, on Friday, being pay day.
[19] As at the date of the incident, Kingstone had not used fencing on any of its sites, but was in the process of introducing this requirement. There was no perimeter fencing erected at the site. Kingstone did not have in place a policy in relation to site security and the erection of site fencing. However, at the time of the incident, Siedlecki and Mr Willis had commenced investigations into the erection of site fencing, including obtaining quotes for site fencing from three fencing companies. Clause 235 of the Occupational Health and Safety Regulation 2001 has the effect that perimeter fencing must be provided for construction of a single dwelling house if a risk assessment identifies the need to isolate particular hazards at the site that cannot be controlled by means other than perimeter fencing.
[20] In May 2003, Kingstone had made inquiries with Garrisons General Insurance Broking in relation to implementing an occupational health and safety management plan for Kingstone.
[21] Prior to the date of the incident, Siedlecki had performed a visual risk assessment of the site. Siedlecki assessed the front veranda of the house to be a risk and accordingly shut off those doors and locked them with a dedicated key. No other measures had been taken to prevent members of the public from accessing the house or the site. Siedlecki had not received instructions from Kingstone in relation to site security.
[22] Prior to incident, Siedlecki was aware that persons, other than employees of Kingstone, and being persons known to be under the age of 18 years, had entered the site without invitation from Kingstone or the owners of the site and removed material from inside the partly constructed house for the construction of ramping on the site. Siedlecki's record of interview dated 6 May 2005 included the following response:
'We didn't really know that the accident had occurred until WorkCover contacted us and I met [the inspector] on site. We had heard that something had happened but had no information. Kids were on site every day, stealing material or removing things from the building, mainly for a skateboard ramp on the driveway, they were removing the Stucco sheets from the garage and taking bricks etc to build the ramp every day especially on weekends. '
Following the incident
[23] Following the incident Kingstone introduced a site fencing policy whereby all construction sites are required to have perimeter fencing installed from the commencement of site works until the week prior to the handover of the site to the client. The perimeter fencing is to be chained and padlocked upon departure from worksites.
[24] This incident alerted Mr Willis to the need for protective fencing at all times. The Company have since instituted a policy of protective fencing at all sites at the instigation of Mr Willis.
