On examination, such a requirement is both practical and common sense. There was a failure to follow such methods in the demolition. This failure was at the heart of the incident.
17 The defendants took almost all of the building structure down before attending to the awnings attached to it. Only a partial corner of a double brick wall was left to hold up the awning which hung over a public walkway. In accordance with the statutory requirements, and even applying a commonsense approach, one would expect the awnings to be removed before the major structure was demolished.
18 The charges for which the defendants are brought before the court and to which they plead guilty is "the offence" and that is what the court must address. Hungerford J in WorkCover Authority of New South Wales (Inspector Carmody) v Consolidated Constructions Pty Ltd (2001) 109 IR 316 re-iterated at [43]:
. . . the penalty is fixed for the offence found to have been proven. It is, therefore, to the offence itself to which attention is to be directed and not . . . the occurrence of the accident and the contribution of other persons for what occurred. (emphasis added)
In Haynes v CI&D Manufacturing Pty Limited (1995) 60 IR 149, the Full Industrial Court in the context of prosecutions under similar provisions in the prior Occupational Health and Safety Act stated (at 158-159):
The general duties created by the OHS Act, such as in ss 15 and 16, are clearly directed, we think at obviating "risks" to safety at the workplace; it would therefore be wrong in considering whether an alleged breach of those general duties had been made out in any particular case to reason from the actual occurrence of an accident, even though causing death or injury, as the necessary detriment to safety and as to which a causal connection was to be shown. The accident itself may well, and probably does, manifest the existence of a detriment to safety and will, no doubt, be some measure of the degree of severity of the detriment; but, it seems to us, it is to the essential ingredients of the offence charged which one must attend by assessing the objective facts causing the detriment to safety and the causal connection therewith of the employer.
19 The incident and the contribution of other identities for what occurred can be used as factors to assist the court to determine the culpability of the defendants as charged. The court is, as was Hungerford J in Consolidated Constructions, assisted by the words of Bauer J in WorkCover Authority of New South Wales (Inspector Twynam-Perkins) v Maine Lighting Pty Ltd (1995) 100 IR 248 (at 257):
Whilst . . . it was natural to concentrate on the events giving rise to the actual cause of the death, such a concentration exhibits an error in law as was pointed out by the Full Court in . . . C I & D Engineering . . . . The actual event of the accident and injury is relevant; but it goes to satisfy the evidentiary burden that (the) failure gave rise to a risk to health, safety or welfare.
20 The defendants relied on an expert's report to propose that a section of the remaining first storey brick wall collapsed due to gusty wind conditions on the day. It is asserted that wind caused the beam holding in place part of the awnings to be wrenched loose from the wall and thereby the awning to fall. The defendants' expert, Mr Dohrmann, viewed the collapse was "most likely" caused "because of the energy of the prevailing winds". While the weather conditions on the day may well have been windy if not gusty, and the site conditions may well have varied, it is not the cause of the accident which is the focus of this consideration of a breach of the Act. Rather, the court examines the risk posed to the safety of both employees and members of the public from this worksite which employed an unsafe system of work.
21 The failure to implement a site-specific work method along with the failure to provide adequate protection overhead and the failure to demolish the building by sequential methods were all systematic failures. Those failures created the risk to safety and gusty winds may have had an effect on what was already a risky building site. The effect of a wind gust on a partially demolished wall cannot be accepted as alleviating the defendants' liability. Further, I find the defendants failed to adequately instruct, inform and train its employees. The risk to safety arose out of the implementation of an unsafe system of work.
22 The defendant company advanced a further proposition: at approximately 11.10 am on the day in question, Mr Burgun had noted some movements in the awning (above Mann Street), so sensibly he ensured all pedestrians were stopped from going under or near the awning at street level. It was only then that a discussion was held as to a means of securing the parapet to which the awning was attached. At about 11.30 am while that discussion was occurring, the parapet, along with the awning, suddenly collapsed. It was submitted the action taken to prevent injury to passers-by from a potential collapse could also alleviate the objective seriousness of the offence. I reject this proposition. The risk to safety objectively existed by the time this ameliorating action was taken. While it was a sensible move by the company director on site and may subjectively be of credit, it cannot be a significant consideration in any objective assessment of the risk to safety.
23 There was therefore an element of foreseeability to the offence, as the work methods adopted were in total breach of those required by the Australian Standards and the New South Wales Regulations under the Occupational Health and Safety Act 2000 (namely, Regulations 246, 247, 249, 250, 251, 253, 256 and 333).
24 The words of Hill J in Tyler v Sydney Electricity (1993) 47 IR 1 are apposite to the circumstances (at 5):
The gravity and the damage or injury actually resulting from the breach does not, of itself, dictate the amount of penalty. However the gravity or otherwise and the potential risks flowing from the breach and its foreseeability are clearly relevant.
