Diesel engine exhaust emissions FAQ
Q1 What are diesel engine exhaust emissions?
Diesel emissions contain fine particulates (DPM), gases and vapours produced by diesel engines. These particles are carcinogenic and can cause serious respiratory disease.
Q2 Why is diesel exhaust dangerous?
DPM contains ultrafine carbon particles linked to lung cancer, asthma, COPD and cardiovascular disease.
Q3 Is there a Workplace Exposure Limit for diesel fumes?
There is no single UK WEL for diesel exhaust. Elemental carbon (EC) is used as a benchmark for controlling DPM exposure.
Q4 Who needs DEEE monitoring?
Any workplace where diesel engines operate indoors or underground, such as vehicle workshops, warehouses, tunnels and logistics centres.
Q5 How is diesel exhaust exposure measured?
We use personal exposure samplers to measure elemental carbon, total carbon and diesel particulates over tasks or full shifts.
