Why this matters
A broken disc or kickback can cause serious cuts and eye injuries in a split second.
What to cover
- Use a disc rated for the grinder's speed and the job.
- Check the disc for cracks and chips before you mount it.
- Never remove the guard.
- Wear a face shield over safety glasses, plus gloves and hearing protection.
- Hold the grinder with both hands and stand out of the line of the disc.
- Wait for the disc to stop before you put the tool down.
Ask the crew
- Where is the disc rating marked?
- What's the right way to change a disc?
- Where do sparks go here?
One thing to do today
Check every grinder for a guard and a matching disc.
