Diesel Engine Exhaust Emissions (DEEE) Monitoring

Protect your workforce from cancer-causing diesel exhaust particulates with expert Diesel Engine Exhaust Emissions (DEEE / DPM) Monitoring from Synergy Environmental Solutions.
We assess worker exposure, identify high-risk activities and provide clear, COSHH-compliant reporting to help you control diesel fumes in your workplace

HGV that could cause exposure to Diesel Engine Exhaust Emissions

What Are Diesel Engine Exhaust Emissions (DEEEs)?

Diesel engine exhaust emissions contain:

  • Diesel particulate matter (DPM)
  • Nitrogen oxides (NO & NO₂)
  • Carbon monoxide
  • Volatile organic compounds (VOCs)

The ultrafine particles in diesel exhaust penetrate deep into the lungs and are classified by IARC as a Group 1 human carcinogen (same category as asbestos and silica).

High exposures occur in:

  • Vehicle workshops & MOT bays
  • Distribution centres & warehouses
  • Tunnelling, mining & underground work
  • Construction sites with plant and machinery
  • Ports, rail depots & haulage yards
  • Fire stations & emergency vehicle bays

If diesel fumes can accumulate indoors — you need DEEE monitoring.

Health Risks of Diesel Exhaust Exposure

Prolonged exposure is linked to:

  • Lung cancer
  • Asthma & respiratory irritation
  • Chronic obstructive pulmonary disease (COPD)
  • Heart and cardiovascular disease
  • Headaches, nausea & short-term breathing difficulties

Because diesel emissions are carcinogenic, COSHH requires exposure to be reduced as low as reasonably practicable (ALARP) — not just “controlled”.

Workplace Exposure Levels & Legal Requirements

Unlike some substances, there is no single UK Workplace Exposure Limit (WEL) for diesel fume.

However:

  • Elemental Carbon (EC) is widely used as a reliable marker of diesel particulate exposure
  • HSE expects exposure to be minimised to the lowest practicable level
  • Some international benchmarks exist for EC and DPM
  • COSHH requires employers to assess and monitor DEEEs where significant exposure may occur
  • LEV, ventilation, maintenance, job rotation and emission reduction controls must be used where risks are identified

Our monitoring service gives you quantitative exposure data to demonstrate compliance and target controls effectively.

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.
