IR light is fundamentally less damaging, but workers in blast furnace environments should be protected against exposure, which has been associated with chronic damage to the human lens.
Exposure to UV light can lead to photokeratitis, a painful experience more commonly known as snow blindness or welder's flash. Sometimes damage occurs without the worker realizing it, because UV and IR radiation cannot be seen. 1Įxposure to UV and IR rays can damage the eyes and the skin. Arc welding and cutting, as well as laser welding, cutting, and brazing, can expose workers to this type of radiation. Radiant energy exposure, also called optical radiation, occurs with work applications that involve intense concentrations of ultraviolet (UV), infrared (IR), and intense visible light.
