Welders face serious safety risks associated with intense light rays. These intense harmful light rays are emitted from the arc and the oxy-fuel flame. You must guard your body against these harmful light rays by wearing proper personal protective equipment. This equipment also helps protect you from grinding sparks, flying slag and weld spatter. You must also put up screens and warning signs when arc welding, cutting or grinding at work sites in the vicinity of the general public. Do not use any high gloss or shiny surfaces for screens, because reflected rays can be just as dangerous. The oxy-fuel torch, and the electric arc give off both visible and invisible light rays. This radiant energy can be divided into three types:
* visible light,
* ultraviolet rays and
* infra-red rays
