SERVICING MULTI-PIECE & SINGLE PIECE RIM/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 CFR part 1915; or the Longshoring Standards, 29 CFR 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 structure 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 ‘‘Multipiece Rim Matching Chart,’’ the National Highway Traffic Safety Administration (NHTSA) publications entitled ‘‘Demounting and Mounting Procedures Truck/Bus Tires’’ and ‘‘Multipiece 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 constrain all rim/wheel components during an explosive 136 Section Nine: Appendix 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 separation or explosion. 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 program to train all employees who service rim/wheels in the hazards involved in servicing those rim/wheels and the safety procedures 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 *29 CFR – Title 29, Labor; Code of Federal Regulations
