ment 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
adjust- ment to the tire or wheel components is
necessary, the tire shall be deflated by removal of the
valve core before the adjustment
(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 com-
ponents shall not be reworked, welded, brazed, or otherwise
(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
(g) Safe operating procedure--single piece rim wheels. The
employer shall establish a safe operating procedure for servic-
ing 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 inflat-
ed 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
(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.
(10) Tires shall not be inflated above the maximum pressure
recommended by the manufacturer to seat the tire bead firmly
against the rim flange.
(11) No heat shall be applied to a single piece wheel.
(12) Cracked, broken, bent, or otherwise damaged wheels shall
not be reworked, welded, brazed, or otherwise heated.
