Which minimum articles of safety gear must be worn when using a bench grinder?
Correct Answer
B. Eye and face protection
Explanation
When using a bench grinder, it is necessary to wear eye and face protection. This is because the grinder can produce sparks, debris, and particles that can cause harm to the eyes and face. Eye and face protection, such as safety glasses or a face shield, can help prevent injuries and ensure the safety of the person using the grinder. Wearing just an apron and gloves, gloves and steel-toed boots, or safety glasses and a long sleeve shirt would not provide adequate protection for the eyes and face.
