During 1985, welders submitted 21% of all claims for eye injuries received by the Workers' Compensation Board of Alberta. Since then the proportion of similar claims has remained high. A descriptive study of welder eye injury claims reveals that, although most injuries are reversible (55% of workers return to work in less than 2 days and 95% in less than 7 days), some workers sustain permanent visual impairment. Eye injuries occur most frequently in metal-work industries, and cold particles, most often metal, are the most common source of injury. Preventive measures should stress the importance of wearing eye protection constantly while working with metal pieces and in metal industries. Goggles probably should not be removed upon extinguishing the welding torch.
