Air Monitoring

Workplace monitoring surveys are intended to assist businesses in fulfilling their obligations; Under Regulation 7 (Prevention or control of exposure to substances hazardous to health) and Regulation 10 (Monitoring exposure at the workplace) of the COSHH Regulations 2004 (as amended).

OHSL offer a monitoring service for most substances deemed hazardous to health, including those substances which have assigned workplace exposure limits (WEL’s) 8 hour time weighted averages (8hr TWA’s) or short-term exposure limits (STEL’s), 15 minute reference periods.
