OH Air Sampling Survey

Requirement to Test / Survey

All UK Employers are required to assess the risks to its employee’s health and safety created by exposure to substances in the work place. Many people are exposed to a variety of substances at work, e.g. chemicals, fumes, dusts etc., which can have a harmful effect on their health.

If exposure to these hazardous substances is not properly controlled, it may cause ill health in a number of ways. To provide guidance, Work place exposure limits exist for various substances which employers must take into consideration as part of their assessment.

A work place assessment / survey can identify problem areas, check control measures are working and indicate where further action may be required

Test / Survey Detail

An initial discussion and walk around survey will enable our consultant to determine the extent of testing required and the kind of monitoring equipment that will be employed and how the survey will be conducted. Also an indication of duration of the survey can now be established. Normally monitoring equipment will be a mixture of static meters, smoke tubes and personal dose meters. The program will be designed to minimise disruption to any working process but may require testing at different periods to capture samples when exposure may be at its highest risk.

Test / Survey Duration

Survey duration will vary dependant on the size of the work place to be tested, accessibility for testing over different shift patterns if required, days or nights etc. A survey could typically be from half a day to 3 days duration. We try to conduct with as little disruption as possible to your routine and will normally conduct the testing and then analyse the data off site. Please bear in mind we will need to test at times of anticipated peak exposure.


Conducting an onsite survey will enable employers to comply with The Control of Substances Hazardous to Health (COSHH) Regulations 2012. All employers who undertake work liable to expose employees must make a suitable assessment of the risk to their health and safety. The risk assessment must also identify the measures needed in order to meet the requirements of the regulations by either eliminating or mitigating the exposure.

Management Report

A detailed report of the survey will provide a comprehensive set of data results which will map and zone all risk areas and sources. The report will contain recommendations and highlight action that needs to be taken
