Background
8 The respondent is a company incorporated on 14 September 1950. It has been in continuous operation since that time. The respondent operates its business in all States and territories in Australia, including national specialist businesses such as rail, telecommunications, power, roads, aviation engineering, water and mining services.
9 As at 18 September 2009 the respondent employed approximately 2,418 employees and 6,659 contractors.
10 At the time of the incident leading to the death of the respondent's employee, Mr McCallum, construction work was being carried out in connection with the Dalrymple Bay Coal Terminal 7X Berth Expansion Project ("the project"). The respondent's role in the project was to construct a duplicate coal loading jetty ("the jetty") beside the existing infrastructure. This work involved the transportation of precast concrete decks by means of a platform supported by two jinkers (the front jinker and the rear jinker) which were propelled by a front end loader (for convenience I will refer to the two jinkers and the front end loader collectively as "the transportation unit", and the front end loader as "the loader"). The jinkers were fitted with an independent steering system operated by way of a hand-held remote control device. Employees designated as jinker operators ordinarily walk beside the jinkers and steer them by means of this remote control device. However there was no separate braking control for the jinkers held by the operators of the jinkers.
11 The loader was owned by the respondent, and the jinkers owned by a third party, Rex J Andrews Pty Ltd ("RJA"). The respondent hired the jinkers in September 2007 for use on the project. RJA conducted training for the safe use and operation of the jinkers in October 2007 with employees of the respondent. One of the persons trained by RJA was Colin Shaw, who in turn provided training to others (including Mr McCallum) in the use of jinkers. Mr McCallum was assessed as competent.
12 On 6 May 2008 Mr McCallum was part of a five man crew tasked with moving a number of precast concrete decks. Colin Shaw was the supervisor of the crew. The other members of the crew were Paul Sudholz (loader operator), Andrew Cribbens (rear jinker operator and spotter) and Phillip Grech (observer). Mr McCallum was the front jinker operator and spotter. He was also the most recent employee of that crew at the time, having commenced employment on 21 April 2008.
13 As the front jinker operator, Mr McCallum's role was to steer the loaded front jinker by way of the remote control device while walking in front of the front jinker on the left hand side of the jetty. The day of the incident was the first time Mr McCallum had operated the jinker arrangement transporting the precast concrete deck on the jetty. He was being observed in the course of performing this role by Mr Grech, an operator with six months relevant experience, whose only duty was to observe Mr McCallum and provide him with assistance and guidance in performing his task.
14 During the year prior to the incident the respondent had carried out a risk assessment and on 26 November 2007 had formulated a work method statement. All members of the crew had received training in relation to the work method statement prepared by the respondent. This statement did not require the maintenance of a safe exclusion zone in front of the moving loader and jinkers, nor did it require that the transportation unit be stopped. In the event obstacles in its path needed to be removed.
15 The operator of the loader performed his duties from a cabin on the loader behind the jinkers and the load they were carrying. When loaded with precast concrete decks, the configuration of the transportation unit prevented the loader operator from observing any part of the area in front of the front jinker or communicating visually with any person located in that area. This was the area in which Mr Grech and Mr McCallum were walking in order to perform their duties.
16 The work procedure on 6 May 2008 required radios to be carried by the operators of the loader, the rear jinker and the front jinker, as well as the supervisor. As an observer, Mr Grech was not issued with a radio.
17 The crew of which Mr McCallum was a member commenced its shift at 6.00 am on the day of the incident. Usual procedures were completed including a Job Hazard Analysis Card and pre-start checks on the plant and vehicles. Mr Sudholz collected three radios, and ensured they were working correctly, had charged batteries, and were on the same channel (channel 9). Mr McCallum received one of the radios. The crew knew how to use the radios based on past experience. However there was, for example, no agreed or established radio communication protocol to ensure that the transmitter of a radio message was able to be informed that the message had been received and understood by its intended recipients.
18 At around midday Mr Daniel Dick, the jetty supervisor, conducted a walk through of the jetty to ensure that the path was clear of obstructions, and to inform people on the jetty that the precast concrete decks were about to be moved along the jetty. Mr Dick later stated that he did not recall during the inspection seeing the planks that subsequently trapped Mr McCallum's foot.
19 After several unsuccessful attempts to move the load up a ramp on to the jetty, the load was successfully moved on to the jetty around 2.30 pm.
20 Once up the ramp and on to the jetty, Mr McCallum signalled via radio to the other members of the crew that it the movement of the load could proceed. At all times the transportation unit was travelling at between four and five kilometres per hour. Mr McCallum and Mr Grech were walking approximately 20 metres in front of the load.
21 Approximately 100 metres along the jetty Mr McCallum called over the radio for the transportation unit to stop, which it did. There was a potential obstruction where a painter crew had been working, which was cleared. Mr McCallum then gave a radio call for the transportation unit to proceed again, which it did.
22 Approximately 50 metres further along the jetty Mr McCallum called over the radio for the transportation unit to slow so that he could straighten the front jinker. This occurred, and the transportation unit proceeded again.
23 It is not in contention that the crew were clearly on the same radio channel and were communicating effectively at this point.
24 At about 800 metres along the jetty Mr Grech noticed an obstruction of approximately five or six wooden scaffolding planks on the jetty, which at that time were approximately 20 metres in front of the front jinker. Mr Grech immediately moved towards the planks and began to remove them. He asked Mr McCallum to radio Mr Sudholz to stop the transportation unit.
25 Mr Grech says that he observed Mr McCallum speak into the radio as if he were making the requested radio call, and that Mr McCallum then began to assist him in removing the planks. Mr Grech did not hear what Mr McCallum said into the radio.
26 Mr Shaw, Mr Sudholz and Mr Cribbens all say that they did not hear any radio communication from Mr McCallum directing Mr Sudholz to stop the transportation unit. As a result, the transportation unit continued moving along the jetty while Mr Grech and Mr McCallum were attempting to clear the planks.
27 Mr Grech and Mr McCallum were out of direct line of sight of all other members of the crew.
28 Mr Grech says he realised that the transportation unit had not stopped, and that he and Mr McCallum were not going to be able to clear the planks in time. Mr Grech moved away, but said it appeared that Mr McCallum's leg was caught amongst the planks as the wheels of the front jinker began to press down and run over the planks. Mr Grech believed that he could not safely assist Mr McCallum to free himself so he ran to the right side of the jetty so that he could gain visual contact with Mr Cribbens to signal the transportation unit to stop. The transportation unit stopped a few seconds later but during this time the front wheels of the front jinker had passed over Mr McCallum's trapped body. Emergency assistance was requested and a paramedic arrived at the scene at 3.00 pm, however nothing could be done to assist Mr McCallum who had suffered fatal injuries.
29 Queensland police and ambulance were notified, and officers arrived on the scene within half an hour. At approximately 4.00 pm the respondent notified Comcare of the incident.
30 The respondent arranged for trained counsellors to attend and speak to all members of the crew individually and any other employees affected. The respondent has also provided its investigation report and established a trust fund to assist Mr McCallum's family following the incident.
31 There appears to be some confusion over the settings of Mr McCallum's radio. An examination of Mr McCallum's radio was carried out by a third party, Trans Communications, on behalf of Comcare, which examination revealed that the radio was set to channel 9, and was found to be well within specification and in excellent working order. However the Queensland Police informed the respondent and Comcare that the radio was found on channel 3.
32 It is not in contention that the respondent has been fully co-operative with all aspects of Comcare's investigation and that it has complied with all statutory notices issued by Comcare in a thorough and timely manner. Further the respondent has voluntarily provided Comcare with a copy of its own internal investigation report and all associated attachments, implemented all of the recommendations of that report, and subsequently undertaken an independent audit of the implementation of the recommendations to ensure their effectiveness.
