Inhaling welding fume is widely known to be hazardous to health, even before the most recent HSE announcement classifying of mild steel welding fume as a human carcinogen. General ventilation does not achieve the essential welding fume exposure control. This is not an acceptable control measure.
Welding fume is a complex mixture of airborne particles, vapours and gases created during the welding process. The fume particles are formed from the vaporisation of molten metal, and the by-product vapours and gases can cause a wide range of adverse health effects.
Control of carcinogenic fumes requires highly effective engineering controls. Local Exhaust Ventilation (LEV), allows for at-source fume extraction which prevents welding fume from spreading to the wider workplace and the worker’s breathing zone.
