Tire and Wheel Service on Equipment
29 CFR 1926.600 · This talk in Spanish
Why it matters
A large equipment tire holds enough compressed air to launch a wheel assembly through a block wall, and split-rim wheels have killed mechanics for a century. Field tire work (plugging, airing up, changing on a trailer shoulder) is where shortcuts meet stored energy. Most of us should do exactly two things with big tires: check pressure with a clip-on chuck, and call the tire service. Today: what is our job and what is not.
Hazards
- ⚠ Explosive separation of multi-piece and split-rim wheels
- ⚠ Overinflated or damaged tires bursting during airing
- ⚠ Zipper failures on the sidewall of overloaded tires
- ⚠ Vehicles slipping off jacks during roadside changes
- ⚠ Heat from welding or brakes triggering tire explosions
- ⚠ Standing in the trajectory while inflating
Controls and safe practices
- ✓ Multi-piece and split rims are specialist work: trained tire techs, cages, and OSHA-required procedures. Not our field job.
- ✓ Inflate with a clip-on chuck and stand outside the trajectory: to the tread side, never facing the rim.
- ✓ Never weld, grind, or heat anything on a wheel with an inflated tire mounted.
- ✓ Check pressures cold with a gauge; underinflation kills tires and overloaded tires kill people.
- ✓ Field changes: firm level ground, rated jack plus stands, wheel chocks, and the vehicle never trusted on the jack alone.
- ✓ Damaged tires (cuts, bulges, exposed cord) get tagged and parked, not aired up harder.
- ✓ Deflate fully before removing any wheel hardware you are qualified to touch.
Crew discussion questions
- Which of our equipment has split or multi-piece rims?
- Who is our tire service, and when do we call instead of touching it?
- Where do people stand when we air up big tires now?
- What jack and stand setup lives on the service truck?
