Which safety practice should be used when operating a grinding wheel?

Wearing protective eyewear is crucial when operating a grinding wheel because the grinding process generates sparks, metal shavings, and dust that can be hazardous to the eyes. Protective eyewear, such as safety glasses or goggles, is designed to shield the eyes from these potential injuries. The risk of serious eye injuries from flying debris or particles is significant, and proper safety gear is an essential part of maintaining a safe working environment.

In addition to eye protection, following other safety protocols, such as ensuring the grinding wheel is undamaged and using appropriate pressure, contributes to safer operation practices. However, the immediate priority is to protect oneself from obvious hazards, which makes wearing protective eyewear a vital safety measure.
