OSHA STANDARD 29 CFR PART 1910.177 - CONTINUED
d.
If a tire on a vehicle is under-inflated but has more than 80 percent 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.
e.
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.
f.
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.
g.
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.
7.
Safe Operating Procedure - Single-Piece Rim Wheels.
The employer shall establish a safe operating procedure for
servicing single-piece rim wheels and shall ensure that employees are instructed in and follow that procedure. The
procedure shall include at least the following elements:
a.
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.
b.
Cracked, broken, bent, or otherwise damaged rim components shall not be reworked, welded, brazed, or
otherwise heated.
c.
Whenever single-piece rim wheels are being handled, employees shall stay out of the trajectory (Figure 3) unless the
employer can demonstrate that performance of the servicing makes the employee’s presence in the
trajectory necessary.
d.
No heat shall be applied to a single-piece wheel or wheel component.
e.
Tires shall be completely deflated by removal of the valve core before demounting.
f.
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 breads while mounting tires on wheels. Tires shall be mounted only on compatible wheels
of matching bead diameter and width.
g.
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.
h.
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.
i.
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).
j.
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.
k.
Tires shall not be inflated when any flat, solid surface is in the trajectory and within one foot of the sidewall.
l.
Employees shall stay out of the trajectory when inflating a tire.
m. Tires shall not be installed to more than the inflation pressure stamped in the sidewall unless a higher pressure is
recommended by the manufacturer.
n.
Tires shall not be inflated above the maximum pressure recommended by the manufacturer to seat the tire bead firmly
against the rim flange.
