Workplace Exposure Monitoring (COSHH)

Workplace Exposure Monitoring 

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).

Workplace exposure 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'.


We offer a free pre-site visit to help determine your key aims and objectives and provide you with a bespoke and competitive quote.  MEC works with you to tackle potential health hazards in the workplace so you can make informed decisions as to what measures you may need to introduce in order to control and minimise employee exposure. 

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


1.   Workplace Air Monitoring (COSHH)


Personal and background air monitoring for a wide range of airborne contaminants, such as hazardous dusts, gases, vapours, mists, fumes, fibres and nanoparticles.  For your information we have provided two SKC sampling guide downloads (UK/US) which will provide more detailed information on the type of airborne contaminants that MEC monitor. 

- UK (HSE) sampling guide

- US sampling guide

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 (COSHH)


Biological monitoring is the analysis of biological samples (i.e. urine, expired air) for the presence of a chemical or its metabolite. The three main exposure pathways to chemicals are inhalation (lungs), dermal (skin) and gastrointestinal (ingestion). Biological monitoring considers the overall systemic exposure (internal dose) and effect (biological effective dose) regardless of the source or pathway.



3.   Dermal Exposure Sampling (COSHH)

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 (COSHH)

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.
