Question: A welder is grinding a weld in an open-air area. They are wearing safety glasses with side shields. Which additional personal protective equipment (PPE) is most crucial to wear as per CSA Z94.3 for eye and face protection during grinding operations?
Answer options: ✅ A full-face shield.
- A welding helmet with a shade 5 lens.
- Specialized UV-blocking contact lenses.
- Tinted sunglasses.
Correct answer: A full-face shield.
Explanation: For grinding operations, safety glasses with side shields protect against direct frontal impact, but a full-face shield is crucial to protect the entire face from flying debris, sparks, and grinding particles, as mandated by CSA Z94.3. A welding helmet with a shade 5 lens is for cutting or very light welding, not grinding, and the other options do not provide adequate impact or particulate protection.
