Vehicle technician connecting a tailpipe exhaust extraction hose to a diesel vehicle in a workshop

Diesel fumes are not just an unpleasant smell. They can irritate the eyes and lungs, contain carbon monoxide and include substances known to cause cancer.

This straight-talking course shows workshop staff how to avoid unnecessary engine running, recognise where fumes can build up, use approved tailpipe extraction and stop when controls fail or symptoms develop.

What you will learn

  • Recognise the main short- and long-term health risks.
  • Identify tasks and places where exhaust can build up quickly.
  • Explain why an open workshop door is not a reliable control.
  • Use the approved engine-running and tailpipe-extraction procedure.
  • Spot obvious extraction faults, visible smoke and warning symptoms.
  • Stop work, report concerns and follow the emergency plan.

Important: This awareness course does not qualify anyone to design, test, repair or certify local exhaust ventilation. Employers must complete a COSHH assessment and provide, maintain and test suitable controls.
