Which minimum article of safety gear is required when using a bench grinder?

When using a bench grinder, the minimum article of safety gear required is eye and face protection. This is critical because bench grinders can produce flying debris, sparks, and metal fragments that pose a significant risk to the eyes and face. Wearing safety goggles or a face shield protects against these hazards, which can result in severe injuries, such as lacerations or eye damage.

Eye and face protection ensures that users maintain visibility while also safeguarding these vulnerable areas from potential harm. While other safety gear, such as ear protection, may help mitigate noise exposure, respiratory masks may protect against harmful dust and particles, and steel-toed boots provide added foot protection, their use is not absolutely necessary for operation specifically concerning the risks associated with bench grinders. The priority is to protect the eyes and face, making this safety gear the most essential for safe operation around this type of equipment.
