WorkSafe is reminding quarry and mine operators of the serious risks involved when safety systems, like seatbelts, are not used while operating powered mobile plant.

Key Points

• Hazards Identified: Not wearing a seatbelt while operating an articulated dump truck (ADT) can result in ejection from the cabin during sudden jolts or impacts.
• Contributing Factors: Excessive speed, sharp braking, and lack of operator competency significantly increase the risk of incidents. In this case, the operator struck a windrow, was ejected from the ADT, and suffered serious injuries.
• Legal Duties: Employers must ensure seatbelts are fitted, maintained, and used on all mobile plant as per the Occupational Health and Safety Act 2004 and OHS Regulations 2017.

Safety Tips

• Install fatigue and distraction monitoring systems in cabs.
• Fit all powered mobile plants with functional seatbelts—check and maintain regularly.
• Use interlocked seatbelts that prevent operation unless buckled.
• Keep cabin windows and doors shut—ensure air conditioning and comms systems are in place.
• Establish and enforce clear site procedures for seatbelt use.
• Verify all operators are trained and competent.

Employer Responsibilities

• Provide and maintain a safe working environment, including safe systems and equipment.
• Identify plant-related hazards and implement practical risk controls.
• Ensure operator protection systems (e.g., seatbelts) are used and maintained.
• Consult with employees and health and safety reps when identifying risks and implementing controls.
• Provide appropriate training, instruction, and supervision to ensure safe operation.

Employee Responsibilities

• Always wear a seatbelt when operating a powered mobile plant.
• Follow site safety protocols and report any hazards or malfunctioning equipment.
• Operate the plant within the limits of your training and competency.
• Avoid unsafe practices, such as operating with open doors or windows.
