OSHA
Regulations
(continued)
(i) When the tire has been driven underinflated at 80% or less of its recommended
pressure, or
(ii) When there is obvious or suspected damage to the tire or wheel components.
(3) Rubber lubricant shall be applied to bead and rim mating surfaces during assembly
of the wheel and inflation of the tire, unless the tire or wheel manufacturer
recommends against it.
(4) If a tire on a vehicle is underinflated but has more than 80% of the recommended
pressure, the tire may be inflated while the rim wheel is on the vehicle provided
remote control inflation equipment is used, and no employees remain in the
trajectory during inflation.
(5) Tires shall be inflated outside a restraining device only to a pressure sufficient
to force the tire bead onto the rim ledge and create an airtight seal with the tire
and bead.
(6) Whenever a rim wheel is in a restraining device the employee shall not rest or lean
any part of his body or equipment on or against the restraining device.
(7) After tire inflation, the tire and wheel components shall be inspected while still
within the restraining device to make sure that they are properly seated and locked.
If further adjustment to the tire or wheel components is necessary, the tire shall be
deflated by removal of the valve core before the adjustment is made.
(8) No attempt shall be made to correct the seating of side and lock rings by hammering,
striking or forcing the components while the tire is pressurized.
(9) Cracked, broken, bent or otherwise damaged rim components shall not be
reworked, welded, brazed, or otherwise heated.
(10) Whenever multi-piece rim wheels are being handled, employees shall stay out
of the trajectory unless the employer can demonstrate that performance
of the servicing makes the employee's presence in the trajectory necessary.
(11) No heat shall be applied to a multi-piece wheel or wheel component.
(f) Safe operating procedure - single piece rim wheels.
The employer shall establish a safe operating procedure for servicing single piece rim
wheels and shall assure that employees are instructed in and follow that procedure.
The procedure shall include at least the following elements:
(1) Tires shall be completely deflated by removal of the valve core before demounting.
(2) Mounting and demounting of the tire shall be done only from the narrow ledge side
of the wheel. Care shall be taken to avoid damaging the tire beads while mounting
tires on wheels. Tires shall be mounted only on compatible wheels of matching
bead diameter and width.
(3) Nonflammable rubber lubricant shall be applied to bead and wheel mating surfaces
before assembly of the rim wheel, unless the tire or wheel manufacturer
recommends against the use of any rubber lubricant.
(4) If a tire changing machine is used, the tire shall be inflated only to the minimum
pressure necessary to force the tire bead onto the rim ledge while on the tire
changing machine.
(5) If a bead expander is used, it shall be removed before the valve core is installed
and as soon as the rim wheel becomes airtight (the tire bead slips onto the bead
seat).
(6) Tires may be inflated only when contained within a restraining device, positioned
behind a barrier or bolted on the vehicle with the lug nuts fully tightened.
(7) Tires shall not be inflated when any flat, solid surface is in the trajectory and within
one foot of the sidewall.
(8) Employees shall stay out of the trajectory when inflating a tire.
(9) Tires shall not be inflated to more than the inflation pressure stamped in the
sidewall unless a higher pressure is recommended by the manufacturer.
