Which statement best describes the use of the grout in a pedestal grinder guard fraction in the given material?

• A. 2/3 of the stone should be covered by the guard
• B. 1/3 of the stone should be covered by the guard
• C. Fully cover the stone
• D. No guarding is required

Answer: (A)

The important idea is how much of the grinding wheel needs to be shielded to protect you if the wheel breaks or shatters. The guard should cover about two-thirds of the wheel’s diameter. This provides a solid safety buffer: enough wheel is protected to keep fragments and sparks away from you, while still leaving a portion of the wheel exposed for grinding control and visibility. Covering only one-third would leave most of the wheel exposed and raise the risk of injury. Fully enclosing the wheel isn’t typically required for operation and isn’t necessary for safety within this standard guidance, and having no guarding at all is unsafe.
