Welding, cutting, and brazing are important but dangerous functions performed by about 500,000 workers in a range of industrial capacities. While welding, cutting, and brazing accidents can be fatal, there are other more common resulting injuries, despite regulations requiring the use of personal protective equipment (PPE). These injuries include exposure to:

• Ultraviolet Radiation (UV), which can damage both skin and eyes.
• Infrared Radiation (IR), which, while less serious, can result in burns.
• Intense visible light, which can permanently and significantly damage the eyes.
• Metal fumes, which can damage the respiratory system.

OSHA has regulations pertaining to welding, cutting, and brazing on their website. They provide their standards for each industry, an analysis of the hazards, solutions, and further information concerning health and safety.
