Cutting and grinding create hazards that range from immediate physical dangers, like abrasions from wheel contact and projectiles from wheel breakage, to long-term health hazards, including hand-arm vibration syndrome, or HAVS, from vibration. The most common injuries are to the head and face.
How Do You Use a Grinder Safely?
Guards, wheel checks, and correct speed prevent most grinding injuries.
- Keep wheel guards in place and working, and replace any that are damaged or missing, since they protect you from the spinning disc and from shattered abrasive wheels
- Check the wheel for cracks and fractures before grinding
- Make sure the wheel and machine run at the recommended speed, since exceeding it can break the wheel and injure you or others
- Use personal protective equipment
- Follow proper storage procedures
- Establish an inspection and maintenance routine
What Are the Steps for Cutting and Grinding?
Work through each step in a controlled way.
- Inspect the cutting tool for wear or damage
- Secure the cutting tool in a holder or fixture to keep it stable
- Select a grinding wheel appropriate for the material and desired finish
- Start the machine and turn on the wheel
- Approach the work in a controlled way and let the wheel’s abrasive particles shave away material to create the desired shape and finish
