“Safe Use of Metal Grinders”
Key Hazards
- Wheel or disc failure causing flying fragments
- Eye and face injuries from sparks, chips, or metal particles
- Kickback from binding, poor control, or incorrect wheel use
- Fire hazards from sparks reaching combustibles
- Burns from hot metal, sparks, or recently ground surfaces
- Noise, vibration, and dust exposure during grinding
2–3 Minute Talk Script
Metal grinders are powerful tools that can remove material quickly, but they can also create serious injuries from sparks, flying fragments, kickback, and wheel contact.
Workers should inspect the grinder before use. Guards, handles, cords or batteries, switches, wheels, flanges, locking nuts, and labels should be checked.
The correct wheel or disc must be used for the grinder speed, material, and task. Cutting wheels, grinding wheels, flap discs, and wire wheels are not interchangeable.
Guards should stay in place and be positioned to protect the worker from sparks, fragments, and wheel contact. Removing a guard increases injury risk.
Workers should maintain firm control and stable footing. A grinder can kick back if the wheel binds, catches an edge, or is forced into the material.
Sparks should be directed away from people, fuel, paper, cardboard, dust, solvents, and other combustible materials. Fire risk should be checked before and after grinding.
Metal can remain hot after grinding. Workers should avoid touching freshly ground surfaces and should warn others when material may be hot.
Safe metal grinding depends on inspection, correct wheel selection, guard use, controlled body position, proper PPE, and stopping immediately if the tool vibrates or behaves unusually.
Safety Reminders
- Inspect the grinder and wheel before use.
- Use the correct wheel for the grinder speed and task.
- Keep guards and handles installed.
- Wear eye, face, hearing, and hand protection as needed.
- Keep sparks away from combustibles.
- Do not force the wheel into the material.
- Treat freshly ground metal as hot.
Ask the Crew
- Is the grinder and wheel in safe condition?
- Is the wheel rated for the grinder speed and material?
- Are guards and handles installed correctly?
- Could sparks reach combustibles or nearby workers?
- What PPE is needed for sparks, noise, debris, and hot metal?
