Worker sustained fatal injuries from tractor rollover

In November 2022, a worker sustained fatal crush injuries when he was ejected from a tractor and trapped underneath as it rolled over. Early investigations indicate that the worker was not wearing a seat belt when driving the tractor along a road while hauling an empty sugar cane bin. For reasons yet to be established, the tractor has overturned and rolled onto its roof.

Investigations are continuing.

IMPORTANT

These findings are not yet confirmed, and investigations are continuing into the exact cause.

Safety issues

Tractors and other agricultural mobile plant are essential for a range of rural operations and activities. They are versatile and can have numerous functions, not only on farms, but many other workplaces. Tractors can be safe when operated properly, however, like any equipment, they can be dangerous if used incorrectly.

Operating tractors and other items of agricultural mobile plant on uneven ground, slight and steep slopes, edges of depressions, contour banks or water courses presents rollover dangers, as does towing or pulling loads. Slopes that can be negotiated safely in dry conditions may be unsafe in the wet, as the tractor can slide.

Tractor operators are most at risk of injury when:

the tractor does not have roll over protection structure
the operator does not wear a fitted seatbelt
the equipment is poorly maintained
working on uneven terrain or rough, slick and muddy surfaces
towing or pulling objects or loads
travelling through pastures where high vegetation obscures stumps and/or potholes
working near dams, ditches, irrigation channels, embankments or over-hanging structures
travelling at high speeds (e.g. on roads).

Ways to manage health and safety

Taking steps to manage risks is a condition of doing business in Queensland. Effective risk management starts with a commitment to health and safety from those who manage the business. If an incident occurs, you'll need to show the regulator that you’ve used an effective risk management process. This responsibility is covered by your primary duty of care in the Work Health and Safety Act 2011.

Use the hierarchy of controls to help decide how to eliminate and reduce risks in your place of work. The hierarchy of controls ranks types of control methods from the highest level of protection and reliability to the lowest. It’s a step-by-step approach to eliminating or reducing risks. You must work through the hierarchy of controls when managing risks, with the aim of eliminating the hazard, which is the most effective control.

Possible control measures to prevent similar incidents

Incidents occur when risks aren't properly assessed and controlled. Some possible control measures include:

a rollover protective structure (ROPS) must be fitted to the tractor in accordance with s.216 Roll-over protection on tractors of the Work Health and Safety Regulation 2011
- ROPS must comply with the design and testing requirements specified in AS1636.1-1996 Tractors – Roll-over protective structures – Criteria and tests or an equivalent standard.
- A ROPS is a structure designed and constructed to prevent or minimise the risk of death or injury to the operator as a result of the tractor rolling over.
a seat belt also prevents the operator from being ejected during use or a roll-over.
- Where the tractor or other agricultural mobile plant is fitted with a seatbelt and a ROPS is present, the seatbelt should be worn by the operator. If a seat belt is not being worn, and the tractor rolls, there’s a strong likelihood the operator will be crushed by the tractor.
logbooks should be maintained to record scheduled maintenance and repairs and any modifications which might affect the safe operation of the tractor.
conducting inspections as well as servicing and maintenance in line with the manufacturer's recommendations.
- For older items of tractors where operating instructions are not available, operational procedures and instructions for use should be developed by a competent person. The PCBU must also provide adequate training to all tractor operators, including the development of safe work procedures in line with the manufacturer's instructions for the operation of a tractor.
assess the environment the tractor will be operating in for potential hazards such as gradient and terrain and determine if the plant is appropriate for the task.
designing tractor implements so that the person fitting the implement does not have to stand between the tractor and implement while the tractor engine is running.
driving tractors at speeds slow enough to keep control over unexpected hazards.
- Operators should watch out for ditches, embankments, and depressions – unstable banks can cause overturns.
never allowing people to ride on tractor carryalls.
not driving on gradients in wet conditions where there is high risk of overturning caused by the tractor sliding or its wheels sinking into the ground.
only towing a load using the designated tow point that is lower than the rear axle height. (Using a tow point higher than the rear axle height can cause the tractor to backflip).
reducing speed before turning or applying turning brakes. Where a differential lock and turning brakes are fitted, ensure the differential lock is disengaged, and the turning brakes are locked together before travelling from one work site to another.
descending slopes cautiously with the tractor in low gear.
when a tractor is bogged in mud or in a ditch, drive out in reverse gear. Logs and planks should only be used behind the rear wheels to increase traction, as using logs and planks in front of the rear wheels increases the chance of the wheels locking which can cause the tractor to backflip.
only climb on or off a tractor that is stopped. Do not dismount while the engine is running unless the transmission is in the neutral or park position and the parking brake is effectively engaged.
When operating a tractor at night or in low light conditions ensure the tractor is fitted with effective lighting (e.g. headlights, worklights at the rear of the tractor, etc).

For hitching implements:

fit attachments according to the manufacturer's instructions.
wherever possible, attach implements with the tractor engine turned off.
ensure any attached implement is maintained and will not fail when attached to the tractor.
if the tractor hydraulics have to be activated while attaching an implement (e.g. adjusting the height of a three-point linkage so that pins can be lined up) stand with your feet outside of the tractor’s wheels, if this is possible.
if there is no option but to stand between the tractor and the implement, with the tractor running, ensure the tractor is in neutral, with the parking brake fully applied. This would be in unusual circumstances due to the physical size of the tractor, the location of the implement attachment points and the need to activate the hydraulics while attaching the implement.
when attaching equipment, always use the mounting points or draw bar provided by the manufacturer. Do not use improvised methods.
do not alter, modify, or raise the height of the draw bar outside of those adjustments made by the manufacturer.
never hitch above the centre-line of the rear axle, around the axle housing or to the top link pin.
do not attempt to adjust or work on implements while they are in motion.
do not use or attach implements unless the power shaft or power take-off (PTO) shaft is guarded.
do not position yourself underneath a raised implement, or wherever you could be crushed, if the tractor hydraulics creep or are inadvertently activated.
if towing a trailer, ensure the load is evenly balanced and well secured. Always operate the vehicle at low speed.

If you are working in a remote area or working alone, always let someone know where you are going and when you are expected back. Also, make sure good communications are in place – for example, assessing mobile phone coverage and using two-way radios.
