Grinding Machine Operator

Abrasive wheel incidents, from wheel bursts and kickback to eye injuries and fires, remain a persistent source of serious harm in fabrication and maintenance work. This one-day course gives operators the knowledge and practical technique to use angle grinders and other handheld grinders safely. Participants learn how abrasive wheels are constructed and marked, how to select the correct wheel for the task, how to inspect and mount wheels, and how to apply guarding, PPE, and work-area controls. The course reflects OSHA requirements and recognized safety practice for abrasive wheel machinery.
