What is identified as the leading cause of injuries when using power saws?

• A. Kickback
• B. Overheating blades
• C. Lack of safety glasses
• D. Excessive noise

Answer: (A)

Kickback is the main danger with power saws. It happens when the cut binds or pinches the kerf in the wood, causing the blade teeth to grab and the saw to be thrust back toward the operator with surprising force. This sudden, violent reaction is why kickback is such a frequent source of injuries—it can occur in an instant and catch you off balance or behind the blade. The risk increases with a dull or misaligned blade, cutting through warped or narrow stock, feeding too quickly, or not keeping the wood flat and supported. To reduce the chance of kickback, keep the blade sharp and properly aligned, use clamps or a push stick to guide the work, ensure the riving knife or blade guard is in place, support the stock to prevent pinching, and feed the saw smoothly without forcing it. Remember to wear eye protection and hearing protection as part of overall safety, but the most effective prevention targets how the blade interacts with the material and how the cut is guided.
