Grinding Hazards And Control Measures

The top 11 common grinding hazards and control measures are explored in this article, which you must understand and implement while conducting the grinding activity.

Handheld grinders are simple to handle and use. However, they can lead to severe injury if adequate safety precautions are not taken or using grinders without wearing proper personal protective equipment (PPE). An angle grinder produces loud noises, sparks, and dust, which can be harmful.

The top 11 common grinding hazards and control measures are mentioned below that must be considered and implemented when using an angle grinder.

The Top 11 Common Grinding Hazards And Control Measures

Grinding Hazards List:

  • Poor maintenance of grinder.
  • Defective electrical cords.
  • Improper assembly of flanges and other parts of an angle grinder.
  • Using grinders with more RPM than the wheel.
  • Cracked grinding wheel.
  • Using grinders without wheel guards and handles.
  • Cracked grinding wheel.
  • Sparks and dust.
  • Loud noise.
  • Using the wrong size of grinding wheels.
  • Not wearing required personal protective equipment.

Safety Control Measures For Grinding Activity Include:

1. Ensure proper maintenance of the grinder machine.

This is crucial to protect the grinders from being damaged and causing unwanted injury. Conduct proper maintenance of the grinder machine at regular intervals and as instructed by the manufacturer. Never use the faulty grinder under any circumstances, and carry out the effective, & preventive maintenance of the grinder machine for their safe operation.

2. Check the grinding wheel and the angle grinder safety guard.

Inspect the grinding wheels for any kinds of defects & cracks before using them. Do not use cutting wheels for grinding purposes in any circumstances. Never use a grinder without a proper angle grinder safety guard, which is provided for protection against grinding sparks & wheel bursts.

3. Check the RPM of grinder machine & grinding wheel.

Ensure that the RPM (Rotation per minute) of grinding machines is always more than the RPM of the grinding wheel. The grinder machine should not rotate the wheels faster than the maximum RPM stated on the wheel.

4. Check the assembly of flanges & other parts of grinding machines.

Ensure that the grinding wheels are assembled and tightened adequately with proper flanges and other parts of the grinding machines. Correct flanges must be used & attached for the smooth rotation of the grinding wheel.

5. Use grinders with cut-off or dead-man switch.

Always select & use the grinders that have automatic cut-off or dead-man switches as part of the handgrip. The purpose of the dead-man switches on the grinding machines is to cut off the power as soon as finger pressure is released. Dead-man switch is a safety device that must be equipped with a grinder.

6. Use the grinding wheel of the right dimension.

This is another crucial thing that the dimensions of grinding wheels must be considered before using them. Using the grinding wheel of proper dimensions plays a good role in ensuring and achieving higher efficiency. This can also help to achieve the maximum RPM of the grinding wheel.

7. Always wear the personal protective equipment (PPE).

Do not operate the grinding machine without wearing proper personal protective equipment, such as hearing protection, safety helmets, goggles, face shields, masks, hand gloves, leather aprons, coveralls, etc. You must check your PPEs before using them to ensure they are in good condition.

8. Never leave the grinder in unattended condition.

This is very important to isolate the grinders from the energy source while not being used. This will help to avoid unauthorized & unwanted operation of grinding machines, which can cause severe injury. Also, isolate the grinding machine from the energy source while replacing the wheels.

9. Ensure a strong grip on the grinder.

You must use two hands to hold the grinders while operating them. One hand will grip the dead-man switch, while the other hand will support the weight of the grinding machine by holding the handle of the grinder. Do not operate the grinder with one hand only, as it can slip from the hand and cause severe injury.

10. Ensure close supervision during grinding activity.

It is crucial to provide close supervision during grinding activity, especially when workers are getting training on how to operate the angle grinders or for people who are unaware of the use of the grinding machines. Proper guidance is mandatory for less experienced workers to ensure the safe use of the grinders.

11. Keep the grinding wheel at the correct degree and secure the grinding piece.

This is very important to position the grinding wheel at the correct degree of 15 to 30. Also, ensure that grinding pieces are adequately secured with a bench vice or using other things to avoid their unwanted movement, which may cause severe injury.

Conclusion

Grinding activity poses significant risks to its users if they do not take adequate safety precautions. In this article, The top 11 grinding hazards and control measures have been explored.
