Summary Statement

This toolbox talk was created by NIOSH and CPWR and covers the hazards associated with power saws. The design allows workers to view a graphic while the facilitator presents the information. After the talk, the sheet can be posted on the jobsite with the graphic side out to reinforce the key points.

CPWR Toolbox Talk logoThousands of people are seriously injured each year by electrical power saws. These injuries also include electrical shock. These tools can do more than just injure a worker, they can kill a worker.

 

Here is an Example

Jason, a carpenter, was remodeling a home. He had finished the wood frame for an outside wall and began to trim the drywall with a power saw. Jason set the depth of the saw blade to 1 inch past the thickness of the drywall. The blade came in contact with the sawhorse and kicked back cutting his arm and torso. His injuries included cut ligaments and tendons in his arm.

Preventing Power Saw Injuries

  • Read the owner’s manual before you first use a saw. Keep blades sharp, clean, and oiled. Inspect blades for cracks.
  • When you use a saw, wear goggles or safety glasses with side shields, even if you wear a face shield. Also wear proper gloves and shoes.
  • Do not wear jewelry, such as chains.
  • Do not wear loose clothes.
  • If you have long hair, tie it inside your hard hat.
  • Do not cut unless you have a clear work area and solid footing.
  • An electric saw needs to be double-insulated or have a 3-prong plug in a grounded outlet.
  • Unplug a saw before you change a blade.
