which the employee is able to understand. (2) The employer shall assure that each employee demonstrates 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 components; (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 equipment required by this section; (v) Handling of rim/wheels; (vi) Inflation of the tire when a single piece rim/wheel is mounted on a vehicle; (vii) An understanding of the necessity of standing outside the trajectory both during inflation of the tire and during inspection of the rim/wheel following inflation; and (viii) Installation and removal of rim/wheels. (3) The employer shall evaluate each employee’s ability to perform these tasks and to service rim/wheels safely, and shall provide additional training as necessary to assure that each employee maintains his or her proficiency. (d) Tire servicing equipment. (1) The employer shall furnish a restraining device for inflating tires on multi- piece wheels. (2) The employer shall provide a restraining device or barrier for inflating tires on single piece wheels unless the rim/wheel will be bolted onto a vehicle during inflation. (3) Restraining devices and barriers shall comply with the following requirements: (i) Each restraining device or barrier shall have the capacity to withstand the maximum force that would be transferred to it during a rim/wheel separation occurring at 150 percent of the maximum tire specification pressure for the type of rim/wheel being serviced. (ii) Restraining devices and barriers shall be capable of preventing the rim/wheel components from being thrown outside or beyond the device or barrier for any rim/wheel positioned within or behind the device; (iii) Restraining devices and barriers shall be visually inspected prior to each day’s use and after any separation of the rim/wheel components or sudden release of contained air. Any restraining device or barrier exhibiting damage such as the following defects shall be immediately removed from service: (A) Cracks at welds; (B) Cracked or broken components; (C) Bent or sprung components caused by mishandling, abuse, tire explosion or rim/wheel separation; (D) Pitting of components due to corrosion; or (E) Other structural damage which would decrease its effectiveness. (iv) Restraining devices or barriers removed from service shall not be returned to service until they are repaired and reinspected. Restraining devices or barriers requiring structural repair such as component replacement or rewelding shall not be returned to service until they are certified by either the manufacturer or a Registered Professional Engineer as meeting the strength requirements of paragraph (d)(3)(i) of this section. (4) The employer shall furnish and assure that an air line assembly consisting of the following components be used for inflating tires: (i) A clip-on chuck; (ii) An in-line valve with a pressure gauge or a presettable regulator; and (iii) A sufficient length of hose between the clip-on chuck and the in-line valve (if one is used) to allow the employee to stand outside the trajectory. (5) Current charts or rim manuals containing instructions for the type of wheels being serviced shall be available in the service area. (6) The employer shall furnish and assure that only tools recommended in the rim manual for the type of wheel being serviced are used to service rim/wheels. (e) Wheel component acceptability. (1) Multi-piece wheel components shall not be interchanged except as provided in the charts or in the applicable rim manual. (2) Multi-piece wheel components and single piece wheels shall be inspected prior to assembly. Any wheel or wheel component which is bent out of shape, pitted from corrosion, broken, or cracked shall not be used and shall be marked or tagged unserviceable and removed from the service area. Damaged or leaky valves shall be replaced. (3) Rim flanges, rim gutters, rings, bead seating surfaces, and the bead areas of tires shall be free of any dirt, surface rust, scale or loose or flaked rubber build-up prior to mounting and inflation. (4) The size (bead diameter and tire/wheel widths) and type of both the tire and the wheel shall be checked for compatibility prior to assembly of the rim/wheel. (f) Safe operating procedure—multi-piece rim/wheels. The employer shall establish a safe operating procedure for servicing multi-piece rim/wheels and shall assure that employees are instructed in and follow that procedure. The procedure shall include at least the following elements: Section Nine: Appendix 137
