The Short Term Effects on Health of Manual Arc Welding
Babcock & Wilcox (Operations) Limited.
Welders' health is affected by the welding process. Fume concentration, which varies with the rod, including the coating, and steel constituents and also the ventilation, may cause watering eyes and respiratory symptoms. Metal fume fever affects welders-particularly in confined situations-although personal susceptibility varies. Non-metallic fume effects, except ozone and phosgene (which may be formed in the presence of hydrocarbons) probably do not occur in sufficient amounts to cause short-term adverse effects. Welding a chrome or lead coated surface can give rise to throat irritation and, in the latter case, raising of the blood lead levels.
The intense light on the exposed eye may result in "arc eye" and infra-red and ultra-violet rays can cause ray burn. Hot metal particles splattering from the weld or produced in the deslagging process give rise to small burns. Damage to the eye, not generally serious, also occurs.
Preheat welding conditions may cause thermal stress. General low humidity and high temperature working environments can lead to dry throats and noses, sore feet and fatigue.
