Oregon Occupational Safety and Health : Abrasive wheel
08/04/1994· Machines that use abrasive wheels are powerful and most operate at high speeds. Some abrasive wheels operate at several thousand revolutions per minute. If a grinding wheel shatters while it is turning, the fragments from the wheel assembly (including the flange, spindle end, and nut) can travel at more than 300 miles per hour. To ensure that abrasive wheels are safely used in your workplace
What You Should Know About Grinding Wheel Guards
OSHA requires a maximum clearance of 1/4" between the grinding wheel and the tongue guard. If a wheel breakage should occur, maintaining the proper distance will help to contain the wheel fragments and reduce the probability of an injury. An example of properly guarded angle grinder.
