How to prevent bench grinder accidents

Share This Post

Because bench grinders are everyday machinery in workplaces, many operators become complacent about their hazards. However, bench grinders are very dangerous when used improperly.

Statistics show that more than half of grinder injuries, such as fingers caught in the machine, or eye and face lacerations, are the result of operator error. Rockford Systems, LLC, a provider of machine safeguarding products and services, offers this primer on grinder safety to help prevent accidents.

Grinder Do’s

  • Always handle and store wheels in a careful manner
  • Visually inspect all the wheels before mounting for possible damage
  • Make sure operating speed of machine does not exceed speed marked on wheel, its blotter or container
  • Check mounting flanges for equal size, relieved as required and correct diameter
  • Use mounting blotters when supplied with wheels
  • Be sure work rest is properly adjusted on bench pedestal and floor stand grinders
  • Always use safety guard that covers a minimum of one-half the grinding wheel
  • Allow newly mounted wheels to run at operating speed, with guard in place, for at least one minute before grinding
  • Always wear safety glasses or some type of approved eye protection while grinding
  • Turn off coolant before stopping wheel to avoid creating an out-of-balance condition

Grind Don’ts

  • Don’t use a wheel that has been dropped or appears to have been abused
  • Don’t force a wheel onto a machine or alter the size of the mounting hole – If a wheel won’t fit the machine, get one that will
  • Don’t ever exceed maximum operating speed established for the wheel
  • Don’t use mounting flanges on which the bearing surfaces are not clean, flat And smooth
  • Don’t tighten the mounting nut excessively
  • Don’t grind on the side of conventional, straight or Type 1 wheels
  • Don’t start the machine until the safety guard is properly and securely In place
  • Don’t jam work into the wheel
  • Don’t stand directly In front of a grinding wheel whenever a grinder is started
  • Don’t grind material for which the wheel Is not designed

It is important to be fully versed in the regulations that outline safe grinder installation, maintenance and operation. Carefully review these sets of regulations before operating any grinding machinery.
