Hand Tool Inspection and Mushroomed Heads
29 CFR 1926.301 · This talk in Spanish
Why it matters
A chisel with a mushroomed head can throw steel chips when struck. Split handles let heads fly loose, and worn jaws slip under load. OSHA holds employers responsible for the safe condition of tools, including tools furnished by employees. Today we take five minutes to look at the tool before we swing it.
Hazards
- ⚠ Steel chips flying off mushroomed chisels, punches, and wedges
- ⚠ Hammer and axe heads flying off split or loose handles
- ⚠ Wrenches with sprung jaws slipping under full pull
- ⚠ Screwdrivers used as pry bars snapping and stabbing
- ⚠ File tangs used without handles puncturing palms
- ⚠ Homemade cheater bars overloading tools past design
Controls and safe practices
- ✓ Grind mushroomed heads back to a clean chamfer before use, or retire the tool.
- ✓ Check handles: cracked, split, or loose handles get replaced, not taped.
- ✓ Use tools for their job: screwdrivers drive screws, pry bars pry, wrenches pull without pipe extensions.
- ✓ Inspect jaws and adjusters on wrenches and pliers; sprung tools slip.
- ✓ Pull on wrenches instead of pushing where possible, with knuckle room planned.
- ✓ Employer-supplied or personal: damaged tools get tagged and pulled either way.
- ✓ Eye protection for striking tools, every strike.
What the OSHA standard says
Exact words from the official text, with a link to each paragraph.
“Wrenches, including adjustable, pipe, end, and socket wrenches shall not be used when jaws are sprung to the point that slippage occurs.”
“Impact tools, such as drift pins, wedges, and chisels, shall be kept free of mushroomed heads.”
“The wooden handles of tools shall be kept free of splinters or cracks and shall be kept tight in the tool.”
