After welding, what eye protection should be used when grinding or chipping slag?

• A. Safety glasses only.
• B. A helmet without a face shield.
• C. No eye protection is needed.
• D. Safety glasses or a face shield over the helmet when grinding.

Answer: (D)

Grinding or chipping slag sends small, hot metal particles flying at high speed. The welding helmet shield helps with arc rays and larger sparks, but it isn’t reliable for protecting eyes from fast debris during grinding. So you add eye protection specifically for flying particles: safety glasses with side shields, or a face shield worn over the helmet to give full-face coverage. Wearing both the helmet and extra eye protection keeps the eyes safe from debris from different angles, and you should use gear that meets safety standards and fits properly.
