Who does hazardous substance testing for businesses?

Hazardous substance testing is usually carried out by occupational hygienists, specialist consultants trained in exposure monitoring, dust measurement, fume assessments, and indoor air quality. Some larger companies have in-house hygienists, but most rely on external professionals.

Accredited laboratories also play a role — they analyse the air samples collected onsite. For businesses, it’s important to choose a provider who understands COSHH, WELs and HSE expectations, otherwise the data won’t be defensible if you ever face an inspection.
