We cannot answer this question completely since the COSHH handbook (available at all good book shops) is quite a large volume and hence it is not possible to put all the information into this guide.

However, we can outline some of the salient points for you. As an employer, it is your duty to ensure that you have a comprehensive risk assessment done with a written report. It may be that you do not have the ability to perform this assessment yourself since it requires such action as measuring the contaminant in the air.

There are commercial Health and Safety Consultants who can perform this assessment for you. Once the risks are known the regulations require the introduction of control measures and the maintenance of these measures. You are also required to monitor the effectiveness of these measures on the health of your staff.
