For example, the ultraviolet radiation generated by the electric arc in the welding process can cause severe burns to the skin and lens damage to the eyes. Workers who use flame cutting equipment are also exposed to infrared radiation, which can cause thermal burns. In addition, the intense light associated with welding, cutting, and brazing can produce a variety of eye problems, including damage to the retina. Many construction projects require the use of compressed gases. Compressed gases create the potential for exposure to chemical and mechanical hazards.
Gases can be flammable, combustible, explosive, poisonous, corrosive, or toxic.
Flammable gases create the potential for fire or explosion. Toxic gases present a danger of asphyxiation, poisoning, and suffocation. In addition, because compressed gases are contained in pressurized metal containers, special storage and handling procedures must be followed to avoid a potential detonation of the container. Falling Objects . Nearly 21,000 American workers were injured by falling objects in 1998.
