Objective factors
7The prosecution relied on three factors to illustrate that the offences were, objectively, "most serious". These were, that the risk to safety was foreseeable; simple and readily available steps were available to the defendant to avoid the risk; and, the likely consequences of the breach of each offence were serious.
8The risk to safety is particularised in each of the amended charges as the risk of the dip-rail frame falling over and crushing workers underneath it. The prosecution submitted, and the Court agrees, that this risk was both known and obvious. The Agreed Facts reveal that Mr Rodgers, during a discussion with the workers assigned to undertake the task, instructed them to sling the top beams (thereby securing the frame) and then to remove the beams. After issuing these instructions he left the area. Despite his clear instruction, Messrs Zappia and Kerr (employees of the defendant) proceeded in reverse order to loosen and remove the hold down nuts on the bottom beams of the structure thereby leaving the dip-rail frame unsecured.
9A Job Safety and Environmental Assessment form (JSEA) prepared by the defendant, specifically for the removal of the outer and inner dip-rail panels on 30 March 2009, expressly adverted to the risk of "crush injuries" when "rigging the outer dip-rail panel for lifting". The signatures of both Mr Zappia and Mr Kerr appear on the Worker Sign On Sheet attached to the JSEA as do the signatures of Messrs Rodgers, Esposito, Neves and Ashton, all employees of the defendant. The document does not contain the signatures of any Allstate employees.
10These facts demonstrate, at minimum, that the risk was foreseeable. It was an obvious risk to safety by reason of the unsecured dip-rail frame's weight (1.7 tonnes) and its dimensions (2.3 metres high by 8.1 metres long).
11The simple steps available to the defendant to obviate the risk are demonstrated by reference to the particulars which appear in the amended charges. These include having in place and enforcing a system of work that:
(i) Required and ensured that the hold down studs for the dip-rail frame would not be removed until the dip-rail frame had been secured or attached to the crane which was to lift it;
(ii) Required and ensured that its employees checked that the hold down studs for the dip-rail frame had not been removed before climbing onto it or continuing to work with it or near it;
(iii) Required and ensured that its employees inform each other when the hold down studs had been removed to the dip-rail frame so that they knew that the dip-rail frame was unsecured and presented a risk;
(iv) Required and ensured that the dip-rail frame was secure at all times when its employees were working in or in the vicinity of the dip-rail frame; and
(v) Ensured that its employees had received adequate training to ensure that they understood the matters set out in (i)-(iv) above.
12Further available steps would also have included the implementation of a risk assessment identifying the risk of the dip-rail frame falling over if the hold down studs were removed prior to securing the frame with the crane, and ensuring that adequate consultation took place with all the workers involved in the work. In addition, an adequate level of supervision of the workers would have prevented the removal of the hold down studs prior to the frame being secured to the crane. The facts do not disclose any reasons why Messrs Zappia and Kerr made the unilateral decision to remove the hold down studs before the frame was secured, contrary to the verbal instruction given by Mr Rodgers. Mr Wormleaton and other members of the Allstate work crew were not made aware of the decision. It should be emphasised, however, that the Court regards this informal method of instruction as an inadequate means of ensuring that the workers followed the particular sequence of work. The conclusion is even more compelling when regard is had to the seriousness of the risk which arose when Mr Wormleaton and other workers were exposed to the unsecured frame weighing about 1.7 tonnes.
13The likely consequences of exposure to the risk were most serious. Given the weight of the unsecured frames, as well as its dimensions, the risk of it falling over and crushing those workers in its vicinity could well have resulted in very serious injuries, even fatal injuries. The fact that Mr Wormleaton suffered very serious injuries demonstrates these likely consequences.
14The objective seriousness of an offence falls to be assessed by reference to the charges, that is, by reference to those acts or omissions, such as the systems of work which the defendant is alleged to have failed to have in place thereby exposing persons identified in the charges to a risk to safety: Morrison v Powercoal Pty Ltd (No 3) [2005] NSWIRComm 61; (2005) 147 IR 117 at [76]. It follows from this observation that a system of work put in place prior to the offence by a defendant that bears no resemblance, or has no connection to the acts or omissions alleged in the charge, has no, or little, relevance to an assessment of the objective seriousness of the offence.
15In the present proceedings, however, the evidence reveals the existence of systems of work in place prior to the offences which serve to mitigate the objective seriousness of the offence. The defendant had in place a system of work specifically directed to the task of removing the outer dip-rail panel. This system was set out in the JSEA generated on 30 March 2009 (to which I have earlier referred). Messrs Zappia and Kerr appear to have been inducted to this system because their signatures appear on the worker sign on sheet. On page 7 of the JSEA, there appear two instructions, nominated as 7 and 8 under the heading "Work Sequence". It was brought to the Court's attention by the prosecution that the instructions on page 7 indicated, or could indicate, the sequence of work intended by the defendant to be undertaken with regard to the removal of the dip-rail panel. Item 7 is headed "Rig Outer Dip-Rail Panel for Lifting". Item 8 is headed "Break Outer Dip-Rail Panel Bolted Connections". On the reasonable assumption that Item 8 refers to the removal of the hold-down bolts, the document on its face does suggest that the intended sequence of work was first to rig the dip-rail panel, and, secondly to remove the hold-down nuts.
16So construed, this suggests that Messrs Zappia and Kerr were made aware of the correct sequence in which the work was intended to occur. In addition to this there is the unchallenged evidence that Messrs Zappia and Kerr were present when Mr Rodgers issued verbal instructions to rig the frame first and then remove the hold-down bolts. When these matters are taken together, the conclusion is available that the error or negligence of the employees impacts, to some extent, on the degree of culpability of the defendant: Inspector Dall v Ullrich Aluminium Pty Ltd [2011] NSWIRComm 156 per Boland J, President, at [48], following Riley v Australian Grader Hire Pty Ltd [2001] NSWIRComm 31; (2001) 103 IR 143 at [15].
17This conclusion takes into account the Court's earlier conclusion that Mr Rodgers' verbal instruction was an inadequate means of ensuring that the employees followed the correct sequence of work. As the documentation demonstrates, the defendant knew the nature of the risk involved in the work. The absence of their signatures on the JSEA Worker Sign-on sheet suggests that Mr Wormleaton and the other members of the Allstate crew were not present when the scope of work set out in the JSEA was explained to the defendant's employees. According to the Agreed Facts the Allstate crew were inducted by Mr Reichardt, "into the specific site at which the work would be undertaken". No further details are forthcoming as to what this induction entailed or what information was given to those workers.
18Before leaving this particular issue, mention should be made of handwritten notation on the JSEA form, which consists of an instruction with regard to work described as "Take dip-rail frame out". The notation alongside this instruction reads, "* cut bolts after load rigged up". It was conceded by the defendant that this entry was made by Mr Rodgers after the incident on 30 March 2009. The prosecution placed no reliance on the timing of the entry as an aggravating factor. Accordingly, it is only mentioned here for the sake of completeness.
19The defendant also relied on a number of procedures which it had put in place prior to the offences, in mitigation of their objective seriousness. These procedures were devised expressly for the testing of the new cooler. They are set out in a lengthy and comprehensive document headed, "Safety Management Plan CO-CM008 - Cooler Trial Assembly and Associated Work". The procedures set out in that Plan have been summarised by the defendant in written submissions and are extracted below:
(a) a comprehensive project safety management plan (PSMP) was drafted and put in place, which required (among other things):
(i) toolbox meetings at the start of each shift or at any time there was a significant change in the job site or job scope;
(ii) completion of JSEA/SWMS to conform to the requirements of the Act;
(iii) lift assessments to be conducted for all crane lifts;
(iv) hazard risk assessments for lifting and loads;
(v) a JSEA checklist; and
(vi) overall project management process;
(b) in accordance with the PSMP, regular (generally weekly) OHS consultation meetings occurred - the most recent prior to the incident occurred on 30 March 2009;
(c) regular audits of HSE practices at the Project were undertaken, including assessments as to whether:
(i) appropriate hazard identification for tasks was being undertaken in for JSEAs, SWMSs, and toolbox meetings;
(ii) all involved had signed the relevant JSEA/toolbox minutes;
(iii) all the controls were implemented to mitigate the hazards.
20The defendant frankly conceded that these processes, although put in place for the testing of the cooler, were deficient in a number of respects. These deficiencies are reflected in the defendant's pleas of guilty to the amended charges. In written submissions, the defendant nominated the following matters, referred to as "The crux of the breach in this case", which illustrate deficiencies in its processes for testing the cooler:
(a) whilst there was a toolbox meeting to discuss the work for the day between Thomas & Coffey employees, and a separate toolbox meeting between Transfield and Allstate employees, there should have been a specific toolbox meeting between the Allstate and Thomas & Coffey teams to discuss the work being undertaken;
(b) at that toolbox meeting, a discussion should have occurred around the Job Safety & Environment Analysis (JSEA), confirming that the load should have been slung prior to the bolts being removed;
(c) supervision with respect to both Thomas & Coffey and Allstate should have ensured that both (a) and (b) should have occurred.
21The existence of the defendant's Plan, and its partial implementation with regard to the work being conducted by the defendant's employees and the Allstate workers on 30 March 2009, demonstrates that the defendant had at least directed its mind to safety issues in connection with the testing of the new cooler, including the dismantling of the dip-rail frames on 30 March 2009. Accordingly, it is appropriate to take these matters into account on the basis that they mitigate, to some extent, the otherwise objective seriousness of the offences.
