Description:In response to a management request, a follow-up evaluation was conducted of optical radiation levels after changes made in the plasma arc cutting (PAC) operations at the Melroe Company (SIC- 3531), Bismarck, North Dakota. The company used PAC in manufacturing skid steer loaders. Measurements were taken of the visible and infrared radiation levels under different operating conditions. Measurements of luminance levels around two of the three PAC units operating at 20 amperes indicated the maximum luminance level documented was 33 candelas per square centimeter when a cut was made along the edge of the metal. This level exceeds guidelines. The maximum infrared radiance level was less than 2 milliwatts per square centimeter at a distance of 8 feet from the arc, which was the closest position the workers would stand while the PAC units were operating. This level was below guidelines. No ultraviolet radiation measurements were made during a second visit as most of the systems used absorb appropriately in this region. Some Melroe workers reported erythemal responses when performing edge cutting. The author concludes that workers were exposed to visible radiation which exceeded occupational limits. The author recommends the use of protective eyewear with at least a shade 4/5 filter.
