The NSW Resources Regulator has launched an investigation into a serious incident at Milbrae-Western Riverina Quarry at Rankin Springs.
Two workers sustained burn injuries when cleaning fluid ignited with a cordless handheld blower about 11.50am on 13 May 2024.
The workers were changing the lubricating oil on a Nordberg HP300 cone crusher using rags and brake cleaning fluid to remove sludge that had accumulated in the oil reservoir.
One of the workers used an 18-volt handheld blower to clean dust and debris from the top of the hydraulic/lubrication unit inside a poorly ventilated purpose-built shipping container.
A small explosion occurred, followed by a fire inside the container.
The injured workers were transported to the local hospital for treatment.
One worker received burns to his face, chest and arms and was transferred to Royal North Shore Hospital in North Sydney. The second worker received less serious superficial injuries and was discharged later that day.
The Regulator is investigating the cause and circumstances of the incident and will examine the equipment involved, hydrocarbons used and stored in electrical installations, as well as training, supervision and work practices.
Mine operators are reminded of their duty under WHS laws to identify hazards and manage risks, including hazardous chemicals.
