What protective measure is primarily designed to shield the welders from UV radiation?

The primary protective measure designed to shield welders from UV radiation is Personal Protective Equipment (PPE). When performing welding tasks, intense ultraviolet light is emitted, which can cause serious skin burns and eye damage, commonly referred to as "welder's flash."

Personal Protective Equipment, such as welding helmets with appropriate filter lenses, protective clothing, and gloves, plays a crucial role in protecting welders from these harmful effects. The helmets are specifically designed to provide an appropriate level of UV protection while also enabling welders to see their work clearly.

While proper ventilation systems focus on removing harmful fumes and gases generated during welding and good housekeeping procedures promote a safer work environment by reducing hazards, these measures do not specifically address the threat posed by UV radiation. Similarly, surface treatments may involve processes that enhance materials but are not directly related to personal protection from UV exposure. Therefore, the focus on PPE is essential for the safety and health of welders in the workplace.
