Key Hazards
- Wheel or disc failure during grinding
- Eye and face injuries from sparks or flying debris
- Cuts or lacerations from rotating wheels
- Fire hazards from sparks and hot metal
- Kickback from binding or poor tool control
- Noise, dust, and vibration exposure
2–3 Minute Talk Script
Grinders are powerful tools that can remove material quickly, but they can also cause severe injuries when wheels fail, guards are removed, or the tool is not controlled. Sparks, flying debris, dust, noise, and rotating parts all need attention.
The grinder should be inspected before use. Workers should check the cord, plug, switch, handle, guard, wheel, disc, flange, and overall condition of the tool before starting the job.
The correct wheel or disc must be used for the tool speed and the material being worked on. A wheel that is damaged, expired, cracked, or not rated for the grinder can fail violently.
Guards should remain installed and properly positioned. Removing a guard may make the job seem easier, but it exposes the worker to wheel fragments, sparks, and direct contact with the rotating disc.
PPE is required for grinder work. Safety glasses, a face shield, gloves, hearing protection, respiratory protection, and flame-resistant clothing may be needed depending on the material and task.
The workpiece should be secured before grinding. Loose material can shift, bind the wheel, cause kickback, or pull the grinder out of the worker’s control.
Sparks should be directed away from people, flammable liquids, dry grass, paper, cardboard, rags, dust, and other combustible materials. Hot work precautions may be needed in some areas.
Safe grinder operation depends on inspection, control, and respect for the tool. If the grinder vibrates, binds, sparks unusually, or feels unsafe, stop and correct the problem before continuing.
Safety Reminders
- Inspect the grinder and wheel before use.
- Use the correct wheel or disc for the tool and material.
- Keep guards installed and properly positioned.
- Secure the workpiece before grinding.
- Wear eye, face, hand, hearing, and respiratory protection as needed.
- Control sparks and remove combustible materials.
- Stop using the grinder if it vibrates, binds, or feels unsafe.
Ask the Crew
- Is the correct wheel or disc installed?
- Are the guard, handle, cord, and switch in safe condition?
- Is the workpiece secured?
- Could sparks reach people or combustible materials?
- What PPE is needed for this grinding task?
