What is the leading cause of injuries related to the use of power saws?

• A. Kickback
• B. Electric shock
• C. Sharp blades
• D. Noise exposure

Answer: (A)

Kickback is the main danger because it causes the saw to leap back toward the operator when the blade binds or the cut pinches. When the wood pinches or binds in the kerf, the blade grabs and can either climb the wood or stop abruptly, sending a sudden surge of force that jerks the saw and piece toward you. That rapid, uncontrolled movement is what leads to the most serious injuries, as you can lose control of the tool and strike yourself, your hands, or nearby surfaces.

To reduce kickback, use proper technique and safety features: keep the blade guard and riving knife in place, align the blade, fence, and wood carefully, and feed the stock steadily rather than forcing it. Use a sharp blade, make relief cuts to prevent pinching, and employ push sticks for narrow stock. Stand to the side rather than directly behind the cut, and maintain a solid stance with both hands on the tool to better resist any sudden kickback.
