Mild Steel Welding Fume


From February 2020, new regulations for the control of Mild Steel Welding Fume was issued by the HSE. Cairn Technology can help you be compliant

The international Agency for Research on Cancer has provided new scientific evidence that the exposure to mild steel welding fumes can cause lung cancer and possibly kidney cancer in humans. Furthermore, the Workplace Health Expert Committee has endorsed the reclassification of mild steel welding fume as a human carcinogen.


Make sure exposure to any welding fume released is adequately controlled using engineering controls (typically LEV).

Cairn Technology has considerable experience of monitoring workplace environments using personal sampling methods which monitors staff exposure to mild steel welding fumes during a normal working period.  On completion of on-site work and resulting analysis, a comprehensive final report containing working methods and monitoring results together with any recommendations will be supplied.


To ensure this is done, we equip each member of staff with personal sampling pumps and monitor their exposure to mild steel welding fumes during a normal working period. We then provide you with a report which details the staff exposure levels and outlines any causes for concern, if any.

We recommend that this monitoring procedure should carried out every 12 months to ensure continued compliance with Regulation 10 of the Control of Substances Hazardous to Health (COSHH) regulations 2002 (as amended).
