A loader fire during tele-remote operations has prompted the NSW Resources Regulator to issue safety recommendations and reinforce the importance of managing fluid power risks at mine sites.

The incident began when a hydraulic hose failed, releasing oil into the engine bay. The loader operator observed a significant oil plume on the rear camera and attempted to move the machine out of the stope.

During this process, the fire suppression system activated but did not fully extinguish the fire. As the operator approached the machine, the fire flared again and was eventually brought under control using a handheld extinguisher.

Cooling operations continued for 30 minutes using a two inch water hose. Workers were relocated to refuge chambers as a precaution while spotters monitored for flare ups.

The investigation identified that the failed hose, which connected the steering pump to the valve, lacked sheathing that could have contained the oil.

As a result, the regulator has recommended that mine operators review and update maintenance systems to ensure that hydraulic hoses are regularly inspected and replaced if found to be worn or cracked. Additionally, hose routing should be managed to prevent unnecessary rubbing or damage from external sources.

To support these recommendations, a set of guidelines is also available to help mine operators manage risks associated with fluid power systems. The guideline outlines how to identify, assess and control health and safety risks throughout the lifecycle of these systems.

It should be considered during a range of activities including risk assessments, system design and installation, commissioning, operation, maintenance and repair. The guideline also applies when reviewing site contracts, introducing new systems to site or reassessing controls following an incident.
