Many operations can result in exposure to a wide variety of hazardous substances in the workplace, which can cause ill-health. Inhalation is a major exposure route and can include dusts, fumes, vapours, fibres, gases and micro-organisms amongst others. Depending upon the substance and the extent of exposure, employees can experience a wide range of adverse health effects potentially leading to a variety of diseases. The Control of Substances Hazardous to Health (COSHH) Regulations 2002 places a duty on the employer to assess and appropriately control any risk of employee ill-health arising from exposure to hazardous substances.
The air monitoring we carry out, will indicate the extent of exposure occurring and highlight the effectiveness of any control measures in place. The results are subsequently compared with relevant exposure limits and interpreted to determine the need for improvements.
Where necessary we advise on the effectiveness of control measures in place and assist in the formulation of appropriate risk management strategies.
The sampling methodology is designed to assess potential operative exposure in accordance with guidance published by the HSE including HSG173 'Monitoring strategies for toxic substances'.
Samples will be taken in accordance with specific Methods of Determining Hazardous Substances (MDHS) issued by the HSE. Visit the HSE website to download detailed guidance notes for specific substances.
When is air monitoring required?
- For a risk assessment under COSHH, to help in selecting the right controls.
- Where there is a serious risk to health from inhalation of the substance.
- To check that exposure limits are not exceeded.
- To check that your exposure controls work well enough, or if you need better.
- To check that new controls work well enough.
- After process or production changes that mean exposure may have changed.
- To show any need for health surveillance.
- As defence against an insurance claim.
- When an HSE Inspector issues you with an 'Improvement Notice' requiring proof that new control measures have been implemented effectively.
