1 The defendants JT & LC Tippett Pty Limited and RD & LF Tippett Pty Limited have been found guilty of one offence each under s 8(1) of the Occupational Health and Safety Act 2000 following defended hearings: Inspector Jones v JT & LC Tippett Pty Ltd and Anor [2007] NSWIRComm 26.
2 As set out in the judgment, the charges concerned events that took place at the defendants' property known as "Whroo" at Kyalite in New South Wales. On 19 January 2004, Anthony Desmond Butcher, Timothy John Willie and Daniel James Peterson, all employed by the defendants to harvest potatoes, were using a potato harvester known as a Grimme Windrower, which was pulled by a tractor. A nip point area on the windrower would, from time to time, become blocked with dirt, debris and pieces of potato which had to be cleared away. A prevailing procedure for accomplishing this task involved disengaging the tractor's power take off (PTO), clearing the debris to unblock the area, re-engaging the PTO, and resuming harvesting.
3 The windrower was constructed of spades for lifting out the potatoes and two independent webbing conveyers: a front conveyer (the first web) and a rear conveyer (the second web). The first web was designed to convey potatoes, soil and foliage from ground level up to an elevated position and then to transfer the potatoes onto the second web. A rubber coated friction drive roller drove the first web from the rear. Along the lower rear corner of the first web and friction drive roller was a counter rotating roller (haulm roller). The purpose of this roller was to create an in-running nip point to grip haulm (potato foliage tops) and pass it forward and out on the ground. At the rear, and below the haulm roller, was the second web. After the haulm was removed, the second web conveyed the remaining potatoes to the rear of the windrower: Inspector Jones v JT & LC Tippett Pty Ltd at [4]. At some stage on 19 January, 2004, during the course of the potato harvesting, the machine became blocked. According to Mr Butcher, Mr Willie attempted to unblock the rollers while standing on the windrower. At the same time Mr Peterson sat in the tractor and turned the PTO on and off during the process. Mr Butcher explained that he climbed onto the second web where it was blocked and attempted to assist Mr Willie clear the blockage. He says at that point both he and Mr Willie were asking Mr Peterson to turn the PTO on and off. He was watching the web under his feet and he saw that it had stopped. At that time (presumably because the second web was not moving) he assumed that the PTO was off. He then says he put his foot on the web and that is when his foot was dragged in between the main web and the counter-rotating roller: Inspector Jones v JT & LC Tippet Pty Ltd at [34].
4 The prosecutor alleged that the defendants failed to provide and maintain a safe system of work for the cleaning of the grimme windrower in that, "a person" could access moving parts of the windrower while cleaning the rollers. The prosecutor had also alleged against both defendants that there was no adequate system of isolating the windrower while the rollers were being cleaned and that the defendants had failed to ensure that the rollers were adequately guarded. The facts and the evidence upon which the allegations were based have been dealt with in detail in my judgment and I do not propose to repeat them here.
5 The defendants come before the Court for sentence following the hearings and the findings of guilt against them in relation to both charges.
6 During the contested proceedings, the prosecutor indicated that the charges apply only to Mr Butcher as an employee. The prosecutor's case against both defendants was that Mr Butcher was at risk of being injured because he could access moving parts of the windrower while cleaning its rollers. The evidence revealed that the windrower contained a number of hazardous components, including the nip point in which Mr Butcher's foot was caught. The risk arose when access was gained to that nip point area while the PTO was engaged and the componentry was operating.
7 The risk to safety, which arose from access to the in-running nip point, was known to the defendants before the accident to Mr Butcher. In the judgment on liability, I reproduced an extract from an interview of John Trevella Tippett, a director of the defendant JT & LC Tippett Pty Ltd. In that interview Mr Tippett nominated various risks or hazards associated with the operation of the windrower, following a question regarding whether a risk assessment had ever been conducted on the machine. He explained that a general risk assessment was undertaken which identified the risks associated with the operation of equipment. The assessment was not documented. According to Mr Tippett, the risks included the PTO shaft, chain and sprockets and moving parts, and the reversing rollers in which Mr Butcher's foot was caught. A simple method of controlling the risk, advanced by Mr Tippett in the interview, was to:
