When are safety guards on a grinder required?

Safety guards on a grinder are required at all times to ensure the protection of the operator and bystanders. These guards serve several critical purposes: they shield the user from flying debris, help contain sparks, and prevent accidental contact with moving parts of the machine, which could lead to serious injuries. The constant requirement for guards reflects the commitment to safety in both shop and field environments, since hazards are present in both settings. The use of guards is a fundamental safety protocol that should never be overlooked regardless of the specific conditions or materials being used.
