SECTION XV:
OSHA STANDARD 29 CFR PART 190.177 (SERVING MULTI-PIECE AND
SINGLE PIECE RIM
WHEELS). (continued)
.
(4)
If a tire on a vehicle is under-inflated 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
(8)
Safe operating procedure—single piece rim wheels.
The
employee 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: before
the adjustment is made.
(9)
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.
(10)
Cracked, broken, bent or otherwise damaged rim components
shall not be reworked, welded, brazed, or otherwise heated.
(11)
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.
(12)
No heat shall be applied to a multi-piece wheel or wheel
component.
(g)
Safe operating procedure—single piece rim wheels.
The
employee 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 breads 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 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 installed 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.
Appendix B – Ordering Information for the OSHA Charts
OSHA has printed two charts entitled “Demounting and Mounting
Procedures for Truck/Bus Tires” and “Multi-piece Rim Matching
Chart”, as part of a continuing campaign to reduce accidents
among employees who service large vehicle rim wheels.
Reprints of the charts are available through the Occupational
Safety and Health Administration (OSHA) Area and Regional
Offices. The address and telephone number of the nearest OSHA
office can be obtained by looking in the local telephone directory
under U.S. Government, U.S> Department of Labor, Occupational
Safety and Health Administration. Single copies are available
without charge.
Individuals, establishments and other organizations desiring single
or multiple copies of these charts may order them from the OSHA
Publications Office, U.S> Department of Labor, Room N-3101,
