Breach of duty of care
34It was not disputed that the appellants as occupiers were under a duty to provide to those working in the shearing shed a reasonably safe place of work, including a reasonably safe means of access between the floor of the shed and the shearing board. The trial judge found that there had been breach of the duty of care in that a non-slip strip should have been placed at the top of the stairs where there was the yellow line at the edge of the shearing board.
35When the shearing shed was constructed in 2003 the appellants sought to follow the recommendations in a WorkCover publication "Health and Safety at Work - Shearing Guide 2002" ("the Guide"). The Guide relevantly referred to clearly identifying the edge of the shearing board visually with paint or tape or installing a guardrail and having steps with a "slip-resistant surface". The parties accepted that the part of the shearing board at the top of the stairs should be regarded as a step.
36Australian/New Zealand Standard AS/NZS 4663:2004 "Slip resistance measurements of existing pedestrian surfaces", which had been introduced in 2002 and updated in 2004, defined "slip resistive" as a pedestrian surface "where the available friction is sufficient to enable a person to traverse that surface without an unreasonable risk of slipping". The shearing board at the top of the stairs complied with AS 4663 as slip resistive. The stairs also complied with AS 1657-1992 "Fixed platforms, walkways, stairways and ladders in design, construction and installation".
37When the shed was at practical completion a co-author of the Guide, Mr Terry O'Connor, who was also a WorkCover inspector or representative of the Australian Workers Union (the evidence was unclear), was invited to inspect it, and he commented that the construction was outstanding. There was no more detailed evidence of his inspection, and in particular of the attention he paid to the stairs. Since the construction of the shearing shed there had been no complaint that the shearing board or the stairs were slippery.
38The appellants' reliance on these matters was met by the respondent's reliance on the evidence of Mr Waddell. Mr Waddell's qualifications were not questioned.
39In Mr Waddell's opinion, there were particular risk factors which called for a non-slip strip at the top of the stairs and on the edge of the nosings of the steps. Non-slip strips at those locations was a measure which was well known as at 2003 and a subject-matter in the 1996 Building code of Australia ("the BCA"). The BCA recommended that stair treads have a non-slip finish or an adequate non-slip strip near the edge of the nosings.
40The factors were that the surface of the shearing board was just at the requisite coefficient of friction; that work in the shed took place at speed; that the respondent (and I take it he meant anyone in his position) had to move from one place to another at regular intervals; and that it was likely that there would be contaminants (meaning sheep urine or excrement picked up in the pens) on the soles of the respondent's shoes as he left the penning area. Mr Waddell said that each of those factors "increases the risk of a slip so for each factor the importance of having a non-slip strip increases". He said that the coefficients of friction in the standards were designed for normal pedestrian conditions, and that the conditions in the shearing shed were not normal because of the factors.
41According to Mr Waddell, and it was not disputed, a non-slip strip at the top of the stairs would have brought a much greater coefficient of friction whereby there was "a very, very low possibility of slipping". He agreed that a non-slip strip would be more prone to have foreign material adhere to it, and so would be more difficult to clean.
42The appellants called no expert evidence in response to the evidence of Mr Waddell. It was apparent from one of Mr Waddell's reports that they had obtained a report of Mr David Beck, upon which he commented. Mr Beck was not called.
43The trial judge correctly said that compliance with the standards was a relevant consideration "but such compliance does not necessarily satisfy the duty of care owed" (at [89]). His Honour came to his conclusion -
"89 It is here relevant to address the issue posed by Mason J in the much cited passage in Wyong Shire Council v Shirt (1980) 146 CLR 40 at 47:
'In deciding whether there has been a breach of the duty of care the tribunal of fact must first ask itself whether a reasonable man in the defendant's position would have foreseen that his conduct involved a risk of injury to the plaintiff or to a class of persons including the plaintiff.'
90 The reasonable person is to be put in the position of the defendants as the occupiers of the shearing shed with a full appreciation as to the nature of the shearing activities and the activities associated with them. The evidence establishes that the shearing operation was not only a busy time for the shearers themselves but for other persons working in the shearing shed. Associated activity included regular use of the stairs in order to gain access to the area behind the board. Response to a call of "Sheepo" required a worker to enter the area behind the board to move sheep into the catching pens. The evidence was that the regular procedure was that sheep were emptied out before entering the shearing shed building. Nevertheless, as Mr Hill acknowledged, some sheep failed to empty out completely and he agreed that it was inevitable that when a large number of sheep were in the shed for the purpose of shearing there would be excrement and urine which dropped onto the timbers (T239). It seems to me that there was a foreseeable risk that those entering the pen area would leave that area with contaminant on their footwear, and would carry that contaminant onto the board and the stairs.
91 I conclude that it was reasonably foreseeable having regard to the nature of the activities being conducted in the course of the shearing operation that a worker might slip at or near the edge of the shearing board, after moving sheep into the catching pens behind it. I am persuaded by the evidence of Mr Waddell and by Mr Rewell's submissions that the exercise of reasonable care in the circumstances called for the provision of a non slip strip on the edge of the board immediately above the stairs which would have been a relatively inexpensive measure and an effective one to eliminate the risk of slipping. In so concluding I accept the uncontradicted evidence Mr Waddell gave as to the effect that the placement of the non slip strip there would have had.
92 Mr Hill agreed that the placement of such a strip would have been safer than having merely a yellow line. Whilst Mr Hill thought that the cleaning of the non-slip strip would be a disadvantage he did acknowledge that he did not know if it would be more difficult to clean. It does not seem to me that any extra cleaning effort associated with the placement of a non slip strip would have imposed an unreasonable demand upon the defendants, particularly in view of the very limited area in which the placement of the non slip strip was rendered desirable. For the reasons stated I find that negligence has been proved."
44There is a difficulty in the trial judge's reasons, although not one on which the appellants relied. The proceedings were governed by the Civil Liability Act 2002 ("the Act"). Determining whether there had been breach of the duty of care required attention to the general principles in s 5B of the Act and, to the extent they arose, the other principles in s 5C. And the passage cited by his Honour from Wyong Shire Council v Shirt (1980) 146 CLR 40 was not the complete exposition by Mason J, but only its commencement referring to foresight of risk of injury; Mason J went on to describe the important task of determining what a reasonable man would do by way of response to the risk and the matters for consideration in doing so.
45Counsel on appeal, who had been counsel at trial, accepted responsibility for failing to address breach of the duty of care through the Act in their submissions to the trial judge. They regarded the general principles as broadly equivalent to the common law approach as expounded by Mason J in Wyong Shire Council v Shirt , and the appellants did not submit that his Honour's conclusion was undermined by failure to attend to the Act in this respect.
46The appellants submitted that, whether on a determination of what the reasonable man would do as spoken of in Wyong Shire Council v Shirt or through regard to the principles in the Act, the trial judge's finding that the exercise of reasonable care required that they put a non-slip strip at the top of the stairs imposed too high a duty on them. In their submission, they were obliged to provide a means of access to and egress from the shearing board which was reasonably safe, and they had done so by constructing the shearing shed in accordance with the Guide; to which they added the inspection by Mr O'Connor and the absence of any complaint, in particular from Mr Alchin. They said that while a non-slip strip would have made the stairs safer, that did not mean that there had been failure to provide stairs which were reasonably safe.
47The appellants did not have to make the stairs as safe as they could possibly be made, but had to take reasonable care under the circumstances. Hindsight should be avoided as a determinant of whether they took reasonable care. As the respondent submitted, however, the Guide was not definitive. A general heading recommended that "the designer/builder should seek the views of experienced yard workers". Steps were one of the areas for "risk assessment", for which "[e]xample control measures" included a slip-resistant surface, but the risk assessments were part of the topic of hazard identification. Under that heading it was said -
"Look at how the worker gets access to the shed, particular [sic] if it is a 'raised' shed. Once in the shed, look at aspects of lay out and design for potential for harm as workers move from and to their work-stations, particularly, shearers moving to and on, the board."
48On the evidence of Mr Waddell, although it was not specifically related to the Guide, there were the particular factors going to risk of injury in use of the stairs beyond the guidance provided by the Guide, whereby the reasonable response to the risk of injury called for non-slip strips on the steps including at the edge of the shearing board at the top of the stairs. Mr Waddell said that the coefficients of friction in the standards were for normal pedestrian conditions on horizontal surfaces, and that the factors "all contribute to some abnormality in that regard".
49It was put to Mr Waddell that "one sees stairs like this without any non-slip strips at the landing in numerous commercial and industrial applications". He answered, "One shouldn't", and that he had not seen many "and when I do I remark that there should be some treatment there because there should". Too much reliance should not be placed on this evidence, since it is imprecise as to the circumstances in which (by inference) non-slip strips were generally found and Mr Waddell's experience with commercial and industrial sites (and with shearing sheds) was not exposed. But Mr Waddell's evidence was replete with reference to the common practice of having non-slip strips on stairs, and the evidence in question is an indication of what was mostly seen in locations akin to the shearing shed with its likelihood of contamination of footwear by urine and excrement, and of what would reasonably be done.
50Having regard to s 5B of the Act, the risk of injury to those working in the shearing shed was foreseeable. It was not insignificant, and while there had not been any previous falls the prospect of a slip and fall was real given the pace of work and the likelihood of contaminated footwear. Even a fall of about 810 mm onto the concrete floor could cause serious injury, and the remedy of a non-slip strip was easy and cheap. A non-slip strip at the top of the stairs, as distinct from the edge of the shearing board elsewhere, would not catch fleeces and impede the shearing operations. Ascribing social utility to sheep-shearing, or to the respondent's duties in the shearing shed, was but touched on in submissions and need not be explored (cf Wilson v Nilepac Pty Ltd [2011] NSWCA 63 at [128]-[130], [171]); shearing has obvious economic desirability, but not such as to reduce simple precautions the reasonable person would take to guard against injury from slipping on stairs in a shearing shed.
51No evidence was led by the appellants to counter that of Mr Waddell. He had prepared his reports on instructions that there was no handrail for the stairs, but it was not suggested that the presence of a handrail (as was in due course found by the trial judge) made any difference to his opinion concerning the particular risk factors.
52The appellants rather faintly submitted that the factor of the speed at which work took place was not made out because the trial judge found that the respondent's complaint that he had to run to keep up with his duties could not be accepted, but there is no doubt that work had to be carried out at some speed. The trial judge accepted Mr Waddell's evidence. In my opinion, no error has been shown in his Honour's acceptance of Mr Waddell's evidence and his conclusion that, despite the attention given by the appellants to compliance with the Guide, the exercise of reasonable care required the non-slip strip.
53It may be noted that in Sheridan v Borgmeyer [2006] NSWCA 201 it was held that the occupiers of a shearing shed were in breach of their duty of care owed to a shearer in failing to have a guard rail at the edge of the shearing board, notwithstanding evidence that it was not common to have a guard rail. An applicable standard required a guard rail. The Guide does not: it says that one should "consider risk of falls from" the shearing board, and installation of a guard rail is suggested as an alternative to identifying the edge of the board with paint or tape. Here also the Guide was not definitive.
