Diesel particulate matter is used as a measure of exposure to diesel engine emissions, and the new limit means employers need to understand where exposure may occur and ensure appropriate controls are in place.
Why this matters
Exposure to diesel engine emissions can have serious health impacts, including lung disease and cancer. Identifying and managing exposure is therefore critical to protecting workers and meeting workplace health and safety obligations.
The new guidance is particularly relevant to workplaces and industries where workers may be exposed to diesel engine emissions, including:
- Mining
- Quarrying
- Tunnelling
- Construction
- Agriculture
- Transport and logistics
- Oil and gas
- Vehicle maintenance
What employers need to know
The new guide provides practical information to help employers:
- Identify sources of diesel engine emissions
- Assess and manage exposure risks
- Implement appropriate controls to protect workers
- Undertake air monitoring and health monitoring
- Prepare for compliance with the new workplace exposure limit
With the new limit taking effect on 1 December 2026, now is the time for employers to understand their potential exposure risks and review their workplace controls.
