The Western Australian Department of Mines, Industry Regulation and Safety has announced changes to the workplace exposure standards for respirable crystalline silica and respirable coal dust.
The original media statement release from Hon Bill Johnston MLA is available via this link.
Respirable crystalline silica
The standard (dated 27 October 2020) states that effective immediately employers must ensure that the workplace exposure standard for respirable crystalline silica does not exceed 0.05 milligrams per cubic metre (eight-hour time-weighted average).
Respirable coal dust
Effective from 27 October 2021, employers must ensure that the workplace exposure standard for respirable coal dust does not exceed 1.5 milligrams per cubic metre (eight-hour time-weighted average).

In Western Australia, we will continue to work closely with our clients around the changes to ensure our services are aligned with the new standards.
