Question: When performing welding operations, what is the primary protective component against arc flash for a welder's eyes?
Answer options:
- Clear safety glasses ✅ Auto-darkening helmet lens
- Tinted prescription glasses
- Side shields on safety glasses
Correct answer: Auto-darkening helmet lens
Explanation: The auto-darkening helmet lens provides crucial protection against the intense ultraviolet (UV) and infrared (IR) radiation produced during arc welding, which can cause arc flash to the eyes. While clear safety glasses protect against impact, they offer no protection against arc radiation. Tinted prescription glasses and side shields are insufficient for arc flash protection.
