TM 9-2610-200-14 D-1 APPENDIX D:  OSHA STANDARD 29 CFR 1910.177 (SERVICING MULTI-PIECE AND SINGLE PIECE WHEELS) §1910.177 Servicing multi-piece and single piece rim   wheels.   (a) Scope. (1) This section applies to the servicing of multi- piece and single piece rim wheels used on large vehicles such   as trucks, tractors, trailers, buses and off-road machines. It does not apply to the servicing of rim wheels used on automobiles, or on pickup trucks and vans utilizing automobile tires or truck tires designated "LT."   (2) This section does not apply to employers and places of employment regulated under the Construction Safety   Standards, 29 CFR Part 1926; the Agriculture Standards, 29   CFR Part 1928; the Shipyard Standards, 29 CRF part 1915; or the Longshoring Standards, 29 CRF part 1918.   (3) All provisions of this section apply to the servicing of   both single piece rim wheels and multi-piece rim wheels unless designated otherwise.   (b) Definitions. Barrier means a fence, wall or other struc-   ture or object 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 U.S. Department of Labor, Occupational Safety and Health Administration 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 Truck/Bus Tires" and "Multi-piece Rim Matching Chart," or any other poster which 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 assemblage 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 an apparatus such as a cage,   rack, assemblage of bars and other components that will con- strain 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 assemblage 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 assemblage 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 or route 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 airblast from a single piece rim wheel may be released. The trajectory may deviate from paths which are perpendicular to the assembled position of the rim wheel at the time of separa- tion or explosion. (See Appendix A of this manual for examples of trajectories.)   Wheel means that portion of a rim wheel which 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).   (c) Employee training. (1) The employer shall provide a pro-   gram to train all employees who service rim wheels in the haz- ards involved in servicing those rim wheels and the safety pro- cedures to be followed.   (i) The employer shall assure that no employee services any rim wheel unless the employee has been trained and instructed in correct procedures of servicing the type of wheel being serviced, and in the safe operating procedures described in paragraphs (f) and (g) of this section.   (ii) Information to be used in the training program shall include, at a minimum, the applicable data contained in the charts (rim manuals) and the contents of this standard.   (iii) Where an employer knows or has reason to believe that any of his employees is unable to read and understand the charts or rim manual, the employer shall assure that the employee is instructed concerning the contents of the charts and rim manual in a manner which the employee is able to understand.   (2) The employer shall assure that each employee demon- strates and maintains the ability to service rim wheels safely, including performance of the following tasks:   (i) Demounting of tires (including deflation);   (ii) Inspection and identification of the rim wheel compo- nents;   (iii) Mounting of tires (including inflation with a restraining device or other safeguard required by this section);   (iv) Use of the restraining device or barrier, and other equip- ment required by this section;   (v) Handling of rim wheels;
