The Western Australian Government has made important changes to the workplace exposure standards for diesel particulate matter (DPM) that applies to all mining operations in the state.
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.
Introducing the exposure standard follows extensive scientific research into DPM exposure risks and consultation with the mining sector.
Hence, it will be implemented immediately as industry should already have controls in place.
The announcement follows the workplace exposure standard for respirable crystalline silica halved to 0.05 milligrams per cubic metre as of 27 October 27 2020; and respirable coal dust will be halved to 1.5 milligrams per cubic metre effective 27 October 2021.
Western Australian Mines and Petroleum Minister, Bill Johnston, said the new workplace exposure standard is a big win for mine workers.
“We will continue to work with the mining sector to ensure operators are managing risks and applying the new diesel particulate matter exposure standard,” Minister Johnston said.
“Healthy mine sites are the bedrock that underpins the McGowan Government’s goal to make Western Australia the world’s safest mining environment.”
