WorkSafe

The McGowan Government has made an important change to the workplace exposure standards for diesel particulate matter (DPM) that applies to all Western Australian mining operations.

Mine operators must now ensure DPM does not exceed 0.1 milligrams per cubic metre of air in the workplace.

DPM is a component of diesel engine exhaust which is a known health hazard for the mining industry, particularly underground mines.

While mine operators were previously encouraged to ensure DPM was kept as low as possible, compliance was voluntary.

L’Haridon Bight Mining Pty Ltd was fined $20,000 in the Perth Magistrates Court on 9 March 2021, after a worker was injured at the company’s Shell Beach Mine located 45km out of Denham in May 2017.

The worker suffered fractures, lacerations and burns after his arm was pulled into the tail-end pulley of a conveyor system of a shell-bagging machine.

• Workplace exposure standard for respirable crystalline silica halved to 0.05 milligrams per cubic metre effective today and respirable coal dust halved to 1.5 milligrams per cubic metre effective October 27, 2021

The McGowan Government has taken steps to reduce the risk of workers contracting potentially deadly lung diseases by halving the workplace exposure standards for respirable crystalline silica (which causes silicosis) and respirable coal dust.

Safe Work Month is held in October each year and encourages employers and workers to promote positive work health and safety in the workplace. This year’s theme is “Staying focused on workplace health and safety”.

While 2020 has involved many challenges, Safe Work Month aims to remind industry and the community that the health and safety of Western Australian workers remains a priority.

The Department of Mines, Industry Regulation and Safety (DMIRS) is working with key resources sector stakeholders to enable the agency to support the sector during the COVID-19 pandemic.

Regular meetings are being held with representative bodies including the Chamber of Minerals and Energy Western Australia, the Association of Mining and Exploration Companies, the Australian Petroleum Production and Exploration Association, and the Amalgamated Prospectors and Leaseholders Association to identify and discuss key priorities and emerging issues.
