38 The limits of the duty under s10(1) to ensure safe premises are set out in s10(3) of the Act. Under s10(3) the duties of a person in relation to ensuring safe premises under s10(1) do not apply to premises used only by employees of the person; or, to premises occupied only as a private dwelling. The duties however, extend to the means of access to or exit from a place of work, but, only apply if the premises is controlled in the course of trade, business or other undertaking (whether for profit or not) of the person.
39 An examination of the available evidence referred to above on this aspect of the charge discloses that:
(i) the premises was used by employees of Top Container;
(ii) the premises was a warehouse facility used for the delivery and storage of goods, which was a business activity conducted by Keralex;
(iii) the particular activity engaged in by Mr Cook at the time of the accident was one taking place inside the premises;
(iv) Keralex had control of the premises in the course of its business, namely, the coordination of delivery and storage of goods.
40 I turn now to consider whether the defendant failed to ensure the premises on 26 September, 2001 was safe.
41 There is no evidence to suggest that there was anything about the physical premises that was unsafe, rather, the activity being conducted on the premises by Mr Cook on 26 September, 2001 was, the prosecutor alleges, unsafe, because no systems of work, and no training, instruction or supervision were provided to ensure the safety of people at work on the day.
42 Many of the cases under s17(1)(a) of the 1983 Act, the predecessor section to s10(1), have dealt with the particular aspect of whether a premises is unsafe by considering whether the physical premises or part of the physical premises was unsafe or whether something attached to or connected to the premises rendered those premises unsafe.
43 Staunton J in Rodney Dale Morrison v Eureka Opal Pty Limited [2005] NSWIRComm 80, considered an offence brought under s17(1)(a) of the Act where the premises was an opal mine in which part of the roof collapsed.
44 In Rodney Morrison v Akula Pty Limited formerly known as Raise Bore Australia Pty Ltd [2004] NSWIRComm 41, another offence under s17(1)(a) of the Act, the risk arose from falling rocks from the top and sides of a mine shaft.
45 Inspector Maltby v Josef and Sons Pty Ltd [2003] NSWIRComm 336, dealt with an the offence under s17(1)(a) and concerned premises described as Kogarah Railway Station and adjoining area. The risk arose when an excavator was operated at the premises close to a charged gas supply line.
46 In Inspector Gabrielle Belley v Rail Infrastructure Corporation [2001] NSWIRComm 323, another s17(1)(a) offence, the risk arose from a narrow railway track clearance which formed part of the premises at Trangie Rail Yard.
47 In WorkCover Authority of New South Wales v McDonald's Australia Limited and Another (1995) 95 IR 383, in which McDonald's was charged under s17(1)(a) of the Act, a worker was fatally injured when he came into contact with an exposed inner core of an electrical cable attached to kitchen equipment known as a clamshell grill.
48 Peterson J in WorkCover Authority of New South Wales (Inspector Buggy) v Newcastle Rail Corporation [2001] NSWIRComm 251 was confronted with a slightly different set of facts for determination as to whether the premises was unsafe under s17(1)(a) of the Act. In that case, a wharf in Newcastle Harbour was rendered unsafe by reason of certain work-related activities (the transportation of shipping containers) which made certain areas of the wharf dangerous areas in which to work: [11], [16].
49 In the present proceedings, it is alleged that the activities of Mr Cook made the premises unsafe for persons, including himself, to use as a place of work, in accordance with s10(1), that is, the premises became unsafe on the evidence, when Mr Cook on 26 September, 2001 stacked the crates in such a way that there was a risk of the crates toppling over and injuring any person in the near vicinity. At the same time, the defendant was in control of the premises by virtue of its role as co-ordinator of the packaging and storage of goods in the premises. In my view, these facts support the finding that the premises were unsafe under s10(1).
Whether there was a risk to safety
50 It remains to consider whether there was a risk to safety and, if so, whether the risk to safety arose by reason of some act or omission on the part of the defendant.
51 According to the Application for Order, the defendant failed to undertake a risk assessment that identified the maximum number of crates that could be safely stacked to ensure stability; and, failed to provide a system of work that ensured that people at the premises were not exposed to the risk of the crates falling on them. In addition, the defendant allegedly failed to provide training, supervision and instruction as was necessary to ensure the crates were safely stacked and to identify risks associated with the stacking of the crates.
52 According to Mr Lomas, on 26 September 2001, one load of Stemcor steel products arrived at the premises. The load consisted of some twelve crates. The crates were stacked on top of each other, six high, against the western wall by the side door. The crates were lifted by means of a forklift. Mr Cook stacked two stacks, six high. Mr Lomas says Mr Cook "would have" started at about 1pm and finished at 2.45pm. Mr Lomas saw Mr Cook stacking the crates at the beginning of the task. At that stage, the stack would have been "three high". A previous load of Stemcor steel products was stacked about a month before by Mr Lomas who stacked three stacks using a forklift and a crane. (Photographs forming part of the evidence taken by the prosecutor on 27 September 2001 confirm that the two stacks of crates stacked by Mr Cook on 26 September 2001 were stacked loose, six feet high.)
53 A report contained in the brief of evidence dated 26 February 2002 and headed "Burnsall Haulage FLT Accident" produces calculations of the angle of tilt required to cause overturning of stacked crates stacked six high. The report was commissioned by the WorkCover Authority of New South Wales and prepared by Senior Inspector Alan Kerruish. The width and height of the crates tested were identical to the dimensions of the crates which toppled over and fatally injured Mr Cook on 26 September 2001. An assumption is made for the purposes of the test that each case or crate in the stack is of equal weight and that the weight in each crate is evenly distributed. The report concludes that a six-crate high loose stack, with its centre of gravity at 3,300 mm above ground level, requires a 456' angle of tilt to cause it to overturn.
54 Although the report does not purport to duplicate the exact conditions existing at the time of the fatal accident, some reliance may nevertheless be placed on it as an indication that the six crates stacked in two loose stacks by Mr Cook at the time of the accident (as the evidence suggests) required only a small angle of tilt in order to give rise to a risk of toppling over.
Whether there was a failure to undertake a risk assessment
