Welding Fume Monitoring
Total and individual metal fume exposure assessment for welders
What Is Welding Fume Monitoring?
Welding fume monitoring measures worker exposure to the complex mixture of metal oxide particles generated during welding, cutting, and brazing operations. IARC classified welding fume as carcinogenic to humans (Group 1) in 2017, prompting regulatory tightening worldwide.
The current WES for total welding fume is 5 mg/m³ TWA-8h. The new WEL reduces this to 1 mg/m³ — an 80% reduction that will require many workplaces to upgrade ventilation, modify processes, or introduce respiratory protection.
How Is It Done?
Personal sampling via inhalable dust cassette or respirable cyclone. Gravimetric analysis for total fume; ICP-MS for individual metals (Mn, Cr(VI), Ni).
When You Need This
- +IARC Group 1 carcinogen classification compliance
- +WEL transition — existing controls may be insufficient at 1 mg/m³
- +Multiple welding processes in confined or semi-enclosed areas
- +Stainless steel or chromium-bearing alloy welding (Cr(VI) risk)
- +Health surveillance programme support
