Airborne hazardous substances are serious health hazards, leading to irritation, sensitization, and carcinogenicity. Workplace air monitoring is undertaken to establish the airborne levels of specific hazardous substances workers are likely to be exposed to within the workplace. 

Workplace air monitoring may be required following concerns over air quality, periodic verification of control measures efficiency or as part of a risk assessment. Workplace air monitoring requirements are usually determined following risk assessments carried out under the Control of Substances Hazardous to Health (COSHH) Regulations 2002. Regulation 10 covers explicitly the monitoring of exposure and provides organizations with measurement data to make informed decisions on the site COSHH assessments.

Element’s highly experienced team of qualified occupational hygienists specializes in delivering a range of workplace air monitoring services for use within a diverse range of operating environments.

Our workplace air monitoring services are undertaken in accordance with the most appropriate UK Methods of Determining Hazardous Substances (MDHS) published by HSE or by internationally recognized standards or methods published by organizations such as NIOSH, BS EN ISO, OSHA.

Our occupational hygienists undertake monitoring using the latest equipment, which is calibrated pre and post sampling. Using portable pumps known volumes of air are drawn through sample media positioned in an individual’s breathing zone or for background measurements fixed in static locations with subsequent analysis for individual airborne contaminants. All sample analytical work is undertaken at ISO accredited analytical laboratories that participate in the externally audited proficiency schemes.

We provide results in interpretive technical reports comparing measured concentrations to Workplace Exposure Limits (WEL) published in the HSE document EH40, Occupational Exposure Limits (OEL) or Control Limits published in HSE Regulations or International OELS (where applicable), which give our customers clear explanations in terms of their compliance with the COSHH and CLAW regulations, and practical advice on appropriate corrective actions and provide control measures where necessary.
