How do we prevent struck-by incidents involving power tools?
Ask the following questions and give time for answers.
- What are the hazards? Powder-actuated fasteners penetrating walls, pneumatic hoses whipping and missing safety devices at the source, grinding wheels shattering, circular saws.
- What are the results? Eye injuries including blindness, face lacerations, head injuries, death
- What should we look for? Defective tools and cords, missing guards, powderactuated tools being used near other trades
Relate this incident or, better, one you know.
Actual Incident: On August 7, 2006, at a Department of Energy facility in Tennessee, a worker was cutting a 6-inch steel water pipe with a gas-powered abrasive wheel when the saw kicked back and struck the worker’s face shield, resulting in a laceration and two fractures to the nose. It would have been much more severe had he not been

How do we prevent these results?
- Wear safety glasses and face shields when working with these tools.
- Make sure workers using powder-actuated tools have been trained. If not, they are a risk to everyone working nearby.
- Never place hand or fingers over the front muzzle end of a powder-actuated tool and always hold the tool perpendicular to the work, insuring the spall guard is in place.
- Inspect tools to insure that protective guards are in place and in good condition.
- Perform ring tests of grinding wheels to determine if they are intact.
- Keep the cord behind the cut to prevent cutting the cord.
- Never stand in line with the unprotected part of a grinding wheel, stand to the side and out of the plane of rotation during start-up. Always wear safety glasses and full-face shields.
- Check electric tools for defects, such as missing grounding pins and cracked cases, before using and always use a GFCI.
