exposure testing

Every year, thousands of workers are made ill by hazardous substances exposure, developing lung diseases such as occupational asthma, cancer and COPD.


As an employer, you are responsible for taking effective measures to control exposure to hazardous substances and protect health. Under the Control of Substances Hazardous to Health Regulations 2002 (as amended) employers are required to protect both employees and others who may be exposed to hazardous substances by ensuring that monitoring procedures are in place to ensure their safety. Solvents and in particular volatile organic compounds (VOC's) are a particular hazard as they become readily airborne in the form of vapours at room temperature.

Typical products containing VOC's that give rise to ill health include:

  • Adhesives (Toluene, Styrene)
  • Solvents (Acetone, Ethyl Acetate)
  • Paints (Dimethylformamyde, Glycol Ethers)
  • Cleaning Agents (Benzene, Xylene)

Our range of testing services and highly experienced technical team ensures we are able to measure exposure in relation to all workplace exposure limits (WEL's) as defined by the health and safety executive document EH40.

ActionsActions and advice

The starting point of a workplace exposure assessment in relation to COSHH is to review the data sheets for all substances used or worked upon.

Once the hazardous substance(s) have been identified an assessment of exposure levels should be conducted by implementing an exposure testing regime. These exposure levels should then be compared with the workplace exposure levels (WEL's) as defined by the Health & Safety Executive. Any actions should then be taken to either reduce or control exposure as part of an ongoing monitoring regime.
