Which of the following PPE is required for welding?

The requirement of a helmet for welding is crucial due to the specific hazards associated with this activity. A welding helmet is designed to protect the welder's face and eyes from several dangers, including intense ultraviolet (UV) and infrared (IR) radiation produced by the welding arc. This radiation can cause severe burns to the skin and permanent damage to the eyes, such as welder's flash or arc eye.

Additionally, welder’s helmets often come with auto-darkening features that adjust the lens shade based on the brightness of the arc, providing better visibility when not welding while still ensuring protection during the welding process. Therefore, the use of a helmet is essential for the safety and health of individuals engaged in welding operations.

While other safety equipment like ear protection, safety goggles, and dust masks may be useful in specific contexts, they do not address the unique risks presented by the welding process as effectively as a welding helmet does.
