The industrial uses, physical properties, and health and safety risks of infrared radiation are discussed. Exposure to infrared radiation occurs in the chemial, construction, metals, food, leather, printing, ruber, plastics, electrical equipmenet, furniture, stone glass, and clay industries. The extent of exposure depends on the wavelength and energy of the infrared radiation, proximity ot ehe source, level of protection with ear sields. appare, tinted goggles, and environmental condidtions. The eye is the critical organ because of its limited ability to dissipate hear and its sensitivity to hear. The skin is also important because of tis large surface area, which is the initial absorber of incident radiation.
