UPDATED 6/2/2019 An operator was ejected from the door of a Load Haul Dump at a metalliferous mine when a parking brake was inadvertently engaged.
According to available regulator reports, a load haul dump (LHD) vehicle was descending a decline in an underground metalliferous mine when its bucket hit a wall. The door inadvertently opened, activating a door interlocking device. The action of the interlock resulted in the application of the parking brake. The operator was ejected from the cab and apparently was not wearing a seat belt at the time of the incident.
The regulator has advised that seat belts and door interlocks must be treated as safety- critical items on the mobile plant.
UPDATED INFORMATION: We have been advised on 6/2/2019 that a local site based investigation has confirmed that there was no evidence of the operator ‘wearing’ or ‘not wearing’ a seatbelt. We stress that the use of a seat belt and installation of seat-belt interlocks may have contributed to lessening the severity potential of the incident.
Site-based personnel have advised that the equipment in the incident was ‘relatively’ new and was not fitted with a manufacturer-installed interlocking seat belt devices that prevent the operation of the LHD unless seatbelts are worn.
The NSW Resources Regulator has highlighted ‘Where defects are identified, the plant must not be operated.’
The regulator has reinforced the provisions of the Work Health and Safety Act 2011 Section 28 detailing worker requirements while at work.
‘This includes complying and co-operating with directions and procedures given, as well as the wearing of seat belts and personal protection equipment’ the regulator stated.
28 Duties of workers

(a) take reasonable care for his or her own health and safety, and
(b) take reasonable care that his or her acts or omissions do not adversely affect the health and safety of other persons, and

(d) co-operate with any reasonable policy or procedure of the person conducting the business or undertaking relating to health or safety at the workplace that has been notified to workers.
