Cutting & Grinding Safety: Hazards & Controls

Key Hazards

• Eye and face injuries from sparks or flying debris
• Wheel or disc failure during operation
• Cuts or lacerations from blades and sharp edges
• Fire hazards from sparks and hot material
• Dust, fumes, and noise exposure
• Kickback from poorly controlled tools or unsecured materials

2–3 Minute Talk Script

Cutting and grinding safety requires controlling rotating wheels and blades, sparks, flying debris, kickback, dust, noise, and hot material. These operations can cause serious injuries when the wrong attachment is used, guards are missing, the workpiece moves, or the tool is not kept under control.

Tools, wheels, discs, and blades should be inspected before use. Cracks, damage, excessive wear, loose handles, missing guards, damaged cords, or incorrect attachments can lead to wheel or blade failure and loss of control.

The wheel or blade should be designed for the tool, material, and operating speed. Using an incorrect or mismatched attachment can cause binding, breakage, kickback, or sudden failure.

Guards should remain installed and properly positioned. Workers should keep their hands and body out of the cutting or grinding path and avoid positioning themselves where fragments would travel if a wheel or blade failed.

The workpiece should be secured before cutting or grinding. Loose material can shift, bind the wheel or blade, create kickback, or cause the tool to move unexpectedly.

Sparks and hot material can create fire hazards. Combustible materials should be removed or protected, and workers should consider where sparks may travel beyond the immediate work area.

Dust, fumes, noise, and flying particles should also be controlled. The material being cut or ground may require ventilation, respiratory protection, hearing protection, eye and face protection, or other task-specific PPE.

Safe cutting and grinding means using the correct tool and attachment, inspecting equipment before use, keeping guards in place, securing the workpiece, controlling sparks and airborne hazards, and stopping immediately if the tool binds, vibrates, or behaves unexpectedly.

Safety Reminders

• Inspect tools, wheels, discs, guards, and cords before use.
• Use the correct wheel or blade for the material.
• Keep guards in place and properly positioned.
• Secure the material before cutting or grinding.
• Wear eye, face, hand, hearing, and respiratory protection as needed.
• Control sparks and remove combustible materials.
• Stop if the tool binds, vibrates, or feels unsafe.

Ask the Crew

• Is the correct wheel or blade being used?
• Are guards installed and properly positioned?
• Is the workpiece secured?
• What PPE is needed for sparks, debris, noise, and dust?
• Could sparks or hot material start a fire?
