How do I stay compliant with diesel emissions in my workplace?

Staying compliant means treating diesel emissions like any other hazardous substance under COSHH regulations. Start with a risk assessment—identify where diesel engines are used, who’s exposed, and how often.

From there, implement control measures:

• Use cleaner alternatives

• Improve ventilation

• Enforce maintenance routines

• Restrict unnecessary idling

• Monitor exposure using air sampling

You should also document everything: your assessments, control strategies, training records, and monitoring results. The HSE expects a clear audit trail if they inspect your site.

Routine re-assessments are key too—especially if your processes change. And don’t forget: just because it’s outdoors doesn’t mean it’s low risk.
