What is necessary when performing welding in areas where other workers are present?

When performing welding in areas where other workers are present, shielding is essential to protect those individuals from the hazards posed by the welding process. Welding generates intense light and ultraviolet radiation, which can cause serious eye damage, including flash burns. Additionally, sparks and metal spatter can be dangerous to nearby workers. By using shielding, such as screens or barriers, the welder can significantly reduce the risk of exposure to these hazards for others in the vicinity.

While increased lighting, supervised practices, and the use of protective clothing are important aspects of safety in general construction and welding, they do not specifically address the immediate need to safeguard nearby workers from the direct effects of the welding operation, which make shielding the priority in this context.
