What is a requirement for the safety guard on an abrasion wheel?

The requirement for the safety guard on an abrasion wheel specifies that it must cover the spindle end, nut, and flange projections. This comprehensive coverage is crucial for ensuring the safety of the operator and bystanders by minimizing the risk of injury from flying debris or accidental contact with exposed components. The safety guard is designed to protect users from hazardous elements that may be present when the abrasive wheel is in operation.

By covering the spindle end, nut, and flange projections, the guard effectively prevents the possibility of these parts becoming potential hazards during use. The complete enclosure not only protects individuals from accidental cuts or injuries but also helps contain any fragments generated during the grinding process, further enhancing workplace safety. Thus, a safety guard that meets this requirement is critical for compliance with safety standards and regulations set forth by OSHA and other governing bodies.
