Workplace Air Monitoring COSHH

Workplace Air Monitoring (COSHH)

Occupational Hygiene is the anticipation, recognition, evaluation, control and prevention of hazards from work that may result in injury, illness, or affect the wellbeing of workers.  Meridian Environmental Consultants Ltd (MEC) utilises expertise in science and engineering to prevent ill health caused by physical and chemical hazards in the working environment, helping employees and employers understand the risks and improve working conditions and working practices.

MEC carry out workplace air monitoring (COSHH), biological monitoring, and both dermal exposure and surface contamination sampling to help you evaluate worker exposures in your workplace. We provide a comprehensive exposure monitoring service to offer you assurance of compliance in accordance with requirements of the Control of Substances Hazardous to Health (COSHH) Regulations 2002 (as amended).

Exposure monitoring or workplace air monitoring means using suitable methods to assess the extent of workers' exposure to hazardous substances via all routes (i.e. inhalation, ingestion and/or skin). For further information download HSE's 'Working with substances hazardous to health: A brief guide to COSHH'.


1.   Workplace Air Monitoring


Personal and background air monitoring for a wide range of airborne contaminants, such as hazardous dusts, gases, vapours, mists, fumes, fibres and nanoparticles.

MEC follow validated national and/or international sampling methods and work with UKAS accredited laboratories to ensure the results you receive are accurate and representative of your work environment. MEC recognise the importance of quality assurance to ensure product and service excellence.

2.   Biological Monitoring


Biological monitoring is the analysis of biological samples (i.e. urine, expired air) for the presence of a chemical or its metabolite.

The method gives an indication of exposure and takes into account all routes of exposure (i.e. inhalation, ingestion and/or skin).

3.   Dermal Exposure Sampling

Dermal exposure to hazardous agents can result in a variety of occupational diseases and disorders, including occupational skin diseases (OSD) and systemic toxicity. To minimise dermal (skin) exposure it is essential to establish which pathways are contributing to the exposure and monitoring provides essential information for preventing or minimising exposures to hazardous substances under COSHH.

4.    Surface Contamination Sampling

Contact with contaminated surfaces can happen in a variety of ways, such as directly handling a contaminated workpiece, contact with contaminated work surfaces, residues on hands transferred to the eyes, nose and mouth, residues on hands transferred to tools, paperwork and food, and removing contaminated PPE incorrectly. Disturbance of contaminated surfaces can lead to inadvertent inhalation, ingestion and skin exposures.
