Type 27 Grinding Wheel Safety

Safety is top priority when using abrasives. Here is a short video on how to keep safe while grinding.

DOs for grinding wheel safety

  1. DO check all wheels for cracks or other damage before mounting.

  2. DO make sure the machine speed does not exceed the maximum operating speed marked on the wheel.

  3. DO use an ANSI B7.1 wheel guard. Position it so it protects the operator.

  4. DO be sure wheel hole or threads fit machine arbor properly and that the flanges are clean, flat, undamaged, and the proper type.

  5. DO run wheel in a protected area for one minute before grinding.

  6. DO wear ANSI Z87+ safety glasses and additional eye and face protection, if required.

  7. DO employ dust controls and/or protective measures appropriate to the material being ground.

  8. DO hold grinder firmly with two hands.

  9. DO support work-piece firmly.

  10. DO read the machine manual, operating instructions, and warnings.

  11. DO read SDS for the wheel and the work-piece material.

  12. DO always HANDLE AND STORE wheels in a careful manner.

DON'Ts for grinding wheel safety

  1. DON’T allow untrained people to handle, store, mount, or use wheels.

  2. DON’T use grinding wheels on pistol grip air sanders.

  3. DON’T use wheels which have been dropped or damaged.

  4. DON’T use a wheel on grinders rotating at speeds higher than the MAX RPM marked on the wheel or on grinders that do not show a MAX RPM speed.

  5. DON’T use excessive pressure when mounting a wheel. Tighten enough only to hold wheel firmly.

  6. DON’T alter a wheel hole or force it on a spindle.

  7. DON’T mount more than one wheel on an arbor.

  8. DON’T twist, bend, or jam any wheel.

  9. DON’T force or bump wheel so that the tool motor slows or stalls.

  10. DON’T remove or modify any guard. ALWAYS use a proper guard.

  11. DON’T use wheels in the presence of combustible materials.

  12. DON’T use wheels near bystanders if they are not wearing protective equipment.

  13. DON’T use wheels for applications other than for which they were designed. Refer to ANSI B7.1 and wheel manufacturer.

  14. DON’T use Type 27 Wheel at a 90° angle.

This list should be used only as a guide. For complete and detailed safety information, refer to ANSI B7.1 Safety Code.
