Safe Work Guidelines
Unless otherwise recommended, apply a nonflammable rubber lubricant suggested by the tire or wheel
manufacturer to the bead and rim mating surfaces during assembly
Do not add air to a tire that was run flat or at 80% or less of its recommended pressure
Do not inflate a truck tire that is flat or when the lock ring is unseated; remove the tire to service it instead
Do not place your hands between dual truck tires when you are inflating them; use a special tire-inflating
extension chuck
Inflate a tire and wheel assembly only when you are sure that the parts are assembled according to the
manufacturer's procedures
Inflate in a safety cage or other restraining device (IER, s.77)
Use a clip-on air chuck with a remote valve and pressure gauge
During inflation, stand clear of the trajectory, or danger zone
Inflate only to the inflation pressure indicated on the tire sidewall
Check that the valve core is not leaking before installing a valve cap
Before removing the inflated tire and wheel from the safety cage or restraining device, inspect them to make
sure that the tire beads and side or lock rings are fully seated; to make an adjustment, deflate the tire
Note: if you notice anything unusual while inflating a tire, stop immediately and deflate the tire to find and correct
the issue.
Hazard: Explosion or Separation of Tire and Rim Assembly
Details
An inflated tire and rim assembly can separate explosively from the force of air pressure in the tire. Damaged or
deteriorated rim and wheel assembly components can fail to restrain the force of the compressed air.
Threat
Serious injury Death
Safe Work Guidelines
Wear approved personal protective equipment (e.g., safety glasses, steel-toed safety shoes, and leather or
canvas gloves, etc.)
Deflate the tire completely before dismounting it
