WAC 296-307-53003 What definitions apply to rim wheel servicing?

Barrier” means a fence, wall, or structure placed between a single-piece rim wheel and an employee during tire inflation, to contain the rim wheel components in the event of the sudden release of the contained air of the single-piece rim wheel.

Charts” means the United States Department of Labor, Occupational Safety and Health Administration (OSHA) publications entitled “Demounting and Mounting Procedures for Truck/Bus Tires” and “Multi-Piece Rim Matching Chart,” the National Highway Traffic Safety Administration (NHTSA) publications entitled “Demounting and Mounting Procedures for Truck/Bus Tires” and “Multi-Piece Rim Matching Chart,” or any other poster that contains at least the same instructions, safety precautions and other information contained in the charts that is applicable to the types of wheels being serviced.

Installing a rim wheel” means the transfer and attachment of an assembled rim wheel onto a vehicle axle hub.

Removing” means the opposite of installing.

Mounting a tire” means the assembly or putting together of the wheel and tire components to form a rim wheel, including inflation. “Demounting” means the opposite of mounting.

Multi-piece rim wheel” means the assembly of a multi-piece wheel with the tire tube and other components.

Multi-piece wheel” means a vehicle wheel consisting of two or more parts, one of which is a side or locking ring designed to hold the tire on the wheel by interlocking components, when the tire is inflated.

Restraining device” means a cage, rack, assembly of bars, or other components that will constrain all rim wheel components during an explosive separation of a multi-piece rim wheel, or during the sudden release of the contained air of a single-piece rim wheel.

Rim manual” means a publication containing instructions from the manufacturer or other qualified organization for correct mounting, demounting, maintenance, and safety precautions peculiar to the type of wheel being serviced.

Rim wheel” means an assembly of tire, tube and liner (where appropriate), and wheel components.

Service” or “servicing” means the mounting and demounting of rim wheels, and related activities such as inflating, deflating, installing, removing, and handling.

Service area” means that part of an employer's premises used for the servicing of rim wheels, or any other place where an employee services rim wheels.

Single-piece rim wheel” means the assembly of single-piece rim wheel with the tire and other components.

Single-piece wheel” means a vehicle wheel consisting of one part, designed to hold the tire on the wheel when the tire is inflated.

Trajectory” means:

  • Any potential path that a rim wheel component may travel during an explosive separation, or the sudden release of the pressurized air; or

  • An area at which an air blast from a single-piece rim wheel may be released.

  • The trajectory may deviate from paths that are perpendicular to the assembled position of the rim wheel. (See Figure for examples of tajectories.)

 

Wheel” means the part of a rim wheel that provides the method of attachment of the assembly to the axle of a vehicle and also provides the means to contain the inflated portion of the assembly (i.e., the tire and/or tube).

(b) Prevent the rim wheel components from being thrown out of the device.

(c) The restraining device is visually inspected before each day's use and after any rim wheel separation or sudden release of contained air. Any damaged restraining device is immediately removed from service.

WAC 296-307-53013 What are the safe operating procedures for servicing multi-piece rim wheels? 

You must establish safe operating procedures for servicing multi-piece rim wheels, and ensure that employees are instructed in and follow the procedures. Your procedures must include at least the following:

(1) Before demounting, remove the valve core to completely deflate the tire.

(2) Remove the valve core to completely deflate the tire before removing a rim wheel from the axle whenever:

(a) The tire has been driven on underinflated at eighty percent or less of its recommended pressure; or

(b) There is obvious or suspected damage to the tire or wheel components.

(3) Apply rubber lubricant to bead and rim mating surfaces during wheel assembly and tire inflation, unless the tire or wheel manufacturer recommends against it.

(4) A tire on a vehicle underinflated at more than eighty percent of the recommended pressure may be inflated while the rim wheel is on the vehicle, only if remote control inflation equipment is used and no employees remain in the trajectory during inflation.

(5) Tires may be inflated outside a restraining device only to pressure sufficient to force the tire bead onto the rim ledge and to create an airtight seal with the tire and bead.

(6) Whenever a rim wheel is in a restraining device, the employee must not rest any part of the body or equipment on the restraining device.

(7) After tire inflation, inspect the tire and wheel components while still within the restraining device. Ensure that they are properly seated and locked. If further adjustment to the tire or wheel components is necessary, deflate the tire by removing the valve core before making adjustments.

(8) Never 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) When handling multi-piece rim wheels, employees must stay out of the trajectory unless the performance of the servicing makes the employee's presence in the trajectory necessary.

(11) Do not apply heat to a multi-piece wheel or wheel component.

[Recodified as 296-307-53013. 97-09-013, filed 4/7/97, effective 4/7/97. Statutory Authority: RCW 49.17.040, [49.17.]050 and [49.17.]060. 96-22-048, 296-306A-53013, filed 10/31/96, effective 12/1/96.]

WAC 296-307-53015 What are the safe operating procedures for servicing single-piece rim wheels? 

You must establish safe operating procedures for servicing single-piece rim wheels, and ensure that employees are instructed in and follow the procedures. Your procedures must include at least the following:

(1) Before demounting, remove the valve core to completely deflate the tire.

(2) Mount and demount tires only from the narrow ledge side of the wheel. Take care to avoid damaging the tire beads while mounting. Only mount tires on compatible wheels of matching bead diameter and width.

(3) Apply nonflammable rubber lubricant to bead and wheel mating surfaces before rim wheel assembly, unless the tire or wheel manufacturer recommends against it.

(4) When using a tire changing machine, inflate tires only to the minimum pressure necessary to force the tire bead onto the rim ledge while on the tire changing machine.

(5) When using a bead expander, remove the bead expander before the valve core is installed and as soon as the rim wheel becomes airtight (the tire bead slips onto the bead seat).

(6) Always inflate tires within a restraining device, positioned behind a barrier, or bolted on the vehicle with the lug nuts fully tightened.

(7) Inflate tires only when the trajectory area is clear of flat, solid objects.

(8) Employees stay out of the trajectory when inflating a tire.

(9) Tires must not be inflated to more than the inflation pressure stamped in the sidewall unless a higher pressure is recommended by the manufacturer.

(10) Tires must not be inflated above the maximum pressure recommended by the manufacturer to seat the tire bead firmly against the rim flange.

(11) Heat must not be applied to a single-piece wheel.

(12) Cracked, broken, bent, or otherwise damaged wheels must not be reworked, welded, brazed, or otherwise heated.
