Tools and Safety

Wear proper eye protection, ear protection, and protective clothing.

Secure hair and loose clothing. Work in areas with good lighting. Make sure all personnel are at a safe distance

before using the tool. Keep tools free of oil, grease, and foreign matter. Use the tool for its designed use. Secure small work in a clamp or vise. Repair or replace damaged tools. Report any injuries to the supervisor.

General Tool Safety

Hand Tools◦ Hand tools are tools that are powered by hand.

Power Tools◦ Power tools are tools that are electrically,

pneumatically, or hydraulically powered for greater efficiency when performing service and repair tasks.

◦ Power tools can be portable or stationary. Portable power tools can be transported with the

operator. Stationary power tools cannot be transported, and are commonly installed in a fixed position.

Power tools may cause serious injury if proper safety procedures are not followed.

Tool Types

Keep tools sharp and in proper working order. Look for wear that could cause an injury, such as a pitted hammer face, damaged insulation on a pliers, or splintered handle.

Point cutting tools away from the body during use.

Grind excess metal from mushroomed chisels.

Organize tools to protect and conceal sharp cutting surfaces.

Hand Tool Safety

Never use a hammer on another hammer. The impact of the hardened surfaces may cause the heads to shatter.

Do not carry tools in a pocket. Transport sharp tools in a holder or with the blade pointed down.

Remove fasteners by pulling the tool toward the body or pushing the tool away from the face

Hand Tool Safety

Follow all manufacturers’ recommended operating instructions.

Use UL or CSA approved power tools that are installed in compliances with the NEC.

Do not use electrical tools on or near a wet or damp area.

Use power tools that are doubled-insulated or have a third conductor grounding terminal to provide a path for fault current.

Ensure power switch is in OFF position before connecting to power source.

Power Tool Safety

Ensure that all safety guards are in place before starting.

Arrange cords and hoses to prevent accidental tripping.

Stand to one side when starting and using a grinder.

Stand clear of operating power tools. Keep hands and arms away from moving parts.

Use tools designed for compressed air service. Shut off, lock out, and tag out disconnect

switches of power tools requiring service.
