In response to a request from Sears, Roebuck and Company (SIC-5311), an evaluation was made of potential exposure of service technicians to optical radiation from a new type of counter cook top. Each of the four cooking areas was 19 centimeters in diameter and contained four infrared radiation (IR) lamps. The lamps had a peak IR wavelength around 1200 nanometers and were able to produce both visible and IR radiation of biological concern. As measured by the spectroradiometer, the cook top with the lid in place did not demonstrate any significant levels of ultraviolet radiation. With the cook top lid removed, luminance values greatly exceeded 1 candela/square centimeter, representing an optical hazard unless protective eyeware or barriers were used. The highest IR level recorded was 128 milliwatts per square centimeter. The author concludes that under certain conditions there may be a hazard to workers servicing the cook top. The author recommends that all servicing of this equipment be done at operating levels less than maximum output. Protective eyeware and gloves should be used if there is a need to operate the equipment at maximum levels. The protective lid should never be lifted with the lamps activated. Broken protective lids should be replaced. Burn hazards as well as eye and skin problems must be guarded against. Vision examinations should be provided for servicemen handling this equipment. Sears may wish to do consumer protection evaluations as well.
