As a result of the said failures, Mark Marchiori was exposed to risk of serious injury.
4 The prosecution has tendered an agreed statement of facts. With respect to the charge brought against the defendant, the following facts are agreed:
[1] The defendant is, and at all material times was:
1.1 duly incorporated with its registered office situated at Buckbitt & Gill, 105 Marius Street, Tamworth, New South Wales;
1.2 engaged in the business of harvesting, or logging, timber.
[2] Prior to the incident the defendant had contracted with the owners of the premises to harvest and remove trees from wooded area located within the premises.
[3] At all material times, pursuant to the said contract, the defendant had control of that part of the premises where logging was being undertaken. The defendant commenced logging in that area in December 2002.
[4] In March 2003, the defendant contracted Marchiori, an independent contractor, to fell trees with a chainsaw at the premises. At all material times, Marchiori was an accredited tree-feller, who had been working as a tree feller for about 10 years prior to the incident.
[5] Marchiori commenced working as a timber feller at the premises on 11 March 2003. Marchiori also worked at the premises as a timber feller on 12 March 2003 and on 17 March 2003 (day of the incident). It was also part of Marchiori's job, when not felling trees, to assist Minett to hook up logs to the skidder.
[6] At all material times, John Glenn Minett (Minett), the sole director of the defendant, was operating a Clark Ranger 666 Skidder (serial No. C9046-818) (the skidder) at the premises. The skidder is a rubber tyred tractor fitted with a bulldozer blade that was used to clear tracks and to drag, or "snig", logs from the felling area.
Incident
[7] At approximately 4pm on the day of the incident, Marchiori sustained serious injury when a sapling, inadvertently pushed over by the skidder driven by Minett, struck him directly on the head.
[8] As a result of the incident, Marchiori suffered a major head injury, which resulted in paraplegia and a certain degree of brain damage. As a consequence, Marchiori is confined to a wheel chair.
[9] Prior to commencing work on 11 March 2003, Minett and Marchiori talked about the way in which they would co-ordinate their activities to maintain a 'safe working distance' between Marchiori and the skidder. The working area was divided into quadrants so that the tree feller and the skidder would be working in different areas. Also, Minett and Marchiori discussed an 'exclusion zone' around the skidder.
[10] However, no specific distance was established, orally or in writing, as the minimum 'safe working distance'.
[11] Also, no specific distance was established, either orally or in writing, for the 'exclusion zone' around the skidder.
[12] The defendant provided no written site safety plan, no safe work method statements, nor any written instructions regarding the 'safe working distance' to be maintained in the felling area and/or the 'exclusion zone' around the skidder. When interviewed after the event, Minett stated that these are matters of common sense.
[13] Communication between skidder operator and the tree feller was based on the skidder operator and the tree feller maintaining visual contact so that they could 'signal' each other. Any verbal communication required the skidder operator and the tree feller to be close enough to talk directly to each other.
[14] On the day of the incident, Marchiori started work at the site prior to Minett. When Minett started work, at about midday, Marchiori was already felling trees. After Minett and Marchiori had lunch, Marchiori was again felling trees whilst Minett was operating the skidder.
[15] Just prior to the incident, Minett saw Marchiori walking towards the area in which Minett was operating the skidder. When Minett first saw Marchiori walking towards the area in which he was operating the skidder, Marchiori was about 100 metres away.
[16] At this time, Minett was both clearing the 'snig track' and 'snigging' logs. On his way to the area in which the logs were to be connected to the skidder, Minett used the blade to push obstacles out of the path of the skidder and to form up the snig track. Then, Minett hooked the logs to the skidder before dragging the logs out to the log dump.
[17] As Minett drove the skidder down to collect more logs, Minett saw that Marchiori has approached to within about 12 to 15 metres of the area in which Minett was operating the skidder. Marchiori was standing at the stump of a tree that he had fallen earlier in the day.
[18] Minett then decided to push two logs off the snig track whilst manoeuvring to have logs attached to the rear of the vehicle. Whilst doing so, the left side of the blade on the skidder came into contact with a root bowl near the snig track after which, Minett looked back in the direction of Marchiori. When Minett looked back to Marchiori, Marchiori was lying on the ground. Minett then stopped the skidder and provided assistance to Marchiori. Minett observed that Marchiori's helmet had been smashed and that he had a gash to the top of his head.
[19] Subsequently, Minett left the scene to call for help. Minett went to the farmhouse located on the property and used the telephone.
[20] Minett then returned to the site and remained with Marchiori until the emergency services arrived and Marchiori was extracted.
Investigation of the Incident Site
[21] On 18 March 2003, Inspector Brian Dell of the WorkCover Authority of New South Wales (WorkCover) visited the premises following receipt of a verbal accident notification from Tamworth Police radio. Inspector Dell made the following observations:
21.1 A yellow Clark Ranger 666 skidder (serial No: C9046-818) parked on track, which ran down a steep North West slope. The front of the skidder was facing directly down the slope (approximately 316° Magnetic) and its blade was lowered to ground level.
21.2 The face of the blade was covered with timber and dirt and on its left side was the butt end a fallen dead tree (tree one). This fallen tree was approximately 13.5m long and 180mm wide at its base. The top of the fallen tree was to the left of the skidder and pointed approximately 250° Magnetic.
21.3 Approximately 3.9m from the blade of the skidder the fallen tree had been jammed in a fork between saplings. The sapling at the topside of this fork was still standing and had been badly burnt at the base. The sapling on the bottom side had been knocked down. The fallen sapling was approximately 13m long and lying on the ground in a direction approximately 290° Magnetic.
21.4 Approximately 11.8m from the point where the fallen tree was jammed in the fork of between the two was the stump of what appeared to be a recently felled tree. Next to this stump and below the fallen section of tree two was a pile of empty plastic bags similar to those used by ambulance officers to store first aid materials and a pile of blue rag. This area was identified to the Inspector as being the site where Mark Marchiori was working at the time of the incident.
21.5 Marchiori has no recollection of events on the day of the incident.
Notices
[22] On 18 March 2003 Inspector Dell issued the following notices:
22.1 Prohibition Notice 117775, requiring the Defendant to maintain control measures to ensure the safety of all persons working in the vicinity of the Clark Ranger 666 rubber tyred skidder.
Conclusions
[23] Based on the Prosecutor's investigations at the site and the answers provided by Minett and Marchiori, it is apparent that:
23.1 Marchiori had been felling trees at the premises with the use of a chainsaw whilst Minett had been utilising the skidder to transport the felled trees up to a log dump on top of the hill at the premises.
23.2 There was to be an exclusion zone between the skidder and Marchiori whilst tree felling was in progress. This was achieved by dividing the logging area up into quadrants with the skidder working in one quadrant while the feller worked in a different quadrant. The premises were divided first along the line of the snig track that ran down the middle of the logging area, and then 'quartered' along the line of a fallen burnt log that was near the snig track.
23.3 The system of work in place on the incident date was that Marchiori would fell trees within a quadrant and then stop. Minett would then enter that quadrant to attach the fallen trees to the back of the skidder to be snigged up to the log dump. At this time Marchiori would no longer be felling trees in that quadrant. Marchiori would then proceed to fell tress in another quadrant, or he would assist Minett in attaching logs to the back of the skidder.
23.4 At the time of the incident, Minett had been travelling down the snig track from the log dump when he saw that Marchiori had ceased felling timber and that Marchiori was moving through the forest towards the snig track where Minett was operating the skidder.
23.5 Minett had a clear view of Marchiori at this time.
23.6 As Minett was driving down the snig track he decided to tidy up the track in order to make his next trip up the hill snigging logs easier. This involved pushing aside two logs that were obstructing the track. Minett sought to push the logs to one side of the track during the course of which, the bade of the skidder came into contact with a large root bowl which as to one side of the track.
23.7 Unbeknownst to Minett, the bowl was still attached to its trunk. That trunk extended to a point where it was wedged between two young saplings. One of the saplings had a deteriorated and rotted base covered by vegetation. and when the skidder pushed the bowl to one side, the trunk 'leaned' against that sapling until the trunk pushed the sapling over. That sapling was approximately 13m in length.
23.8 At this stage Marchiori was standing to one side of the tree stump some twelve metres from the skidder, apparently refuelling his chainsaw, when the sapling was pushed over. The sapling fell directly on top of him and struck him on the head, shattering his safety helmet.
Safe systems of work
23.9 The defendant implemented safe systems of work for wearing helmets and hearing protection.
23.10 The defendant had also made provision for communicating with emergency services in the event of an accident.
23.11 The defendant did not prepare or document a safe work method statement for tasks associated with timber logging operations at the premises.
23.12 The defendant had devised the quadrant system of exclusion zones following an informal risk assessment. The quadrant system increased the likelihood of safe working distances between the tree feller and the skidder whilst tree felling and snigging was occurring simultaneously. However, provisions or systems had not been devised to address the circumstances in which Marchiori was injured.
23.13 The defendant was not aware of the WorkCover Code of Practice for Safety in Forestry Harvesting operations dated 2002. Chapter 8 of the Code sets out requirements in relation to snigging operations.
Safe working distance
23.14 The defendant did not set a minimum safe working distance between persons and machine operations on the basis that the distance would vary depending upon the task being performed and the tree height.
23.15 The exclusion zones tended to result in a safe working distance between persons and machine operations when tree felling and snigging was in progress simultaneously. Persons could, however, be present in different quadrants and still be at an unsafe proximity to machine operations on the snig track separating the quadrants or another zone. The defendant should have ensured that a minimum safe working distance or exclusion zone of twice the height of the trees being felled be maintained from the active tree felling zone [i.e. where Marchiori was felling trees].
23.16 The defendant should also have put in place an exclusion zone around the skidder so that when Marchiori approached within 'two tree lengths' of the skidder, the skidder ceased operations.
Communications
23.17 Minett did not communicate to Marchiori his intention to operate the skidder to clear the bowl of the fallen tree at the time of the incident. Accordingly, Marchiori had no opportunity to take precautions to avoid the falling timber.
5 In addition to the agreed statement of facts, the prosecution tendered an indexed bundle of documents including a factual report of Inspector Brian Dell, dated 18 March 2003.
