Rims, rim bases, side rings, or lock rings that are bent out of shape, pitted from corrosion, broken, or cracked shall not be used or welded, brazed, or otherwise heated in an attempt to repair them. The defective components shall be rendered unusable for tire mounting.(3) Tires shall be completely deflated by removing the components.(4) A restraining device, as defined in R 408.17206(2), shall be provided by the employer and maintained in a safe condition and shall be in compliance with all of the following requirements: (a) 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 that occurs at 150% of the maximum tire specification pressure for the type of rim wheel being serviced.(b) 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 that is positioned within or behind the device.(c) Restraining devices and barriers shall be visually inspected before each day's use and after any separation of the rim wheel components or sudden release of contained air. A restraining device or barrier that exhibits evidence of damage, such as any of the following defects, shall be immediately removed from service: (ii) Cracked or broken components.(iii) Bent or sprung components caused by mishandling, abuse, tire explosion, or rim wheel separations.(iv) Pitting of components due to corrosion.(v) Other structural damage that would decrease the effectiveness of the restraining device or barrier.(d) A restraining device or barrier that is removed from service shall not be returned to service until it is repaired and reinspected. A restraining device or barrier that requires structural repair, such as component replacement or rewelding, shall not be returned to service until it is certified by either the manufacturer or a registered professional engineer that the device or barrier meets the strength requirements specified in subdivision (a) of this subrule.(5) A clip-on chuck with a sufficient length of hose to permit the employee to stand clear of the potential trajectory (see figure 1) of the wheel components and an inline valve with a gauge or a pressure regulator preset to the desired pressure shall be furnished by the employer and used to inflate tires.(6) Industry-accepted tire lubricant shall be applied to the bead and the rim mating surfaces during assembly of the tire and wheel.(7) When a tire is in a restraining device, an employee shall not rest or lean any part of his or her body or equipment on or against the device.(8) An attempt shall not be made to correct the seating of the wheel components, rim, rim base, or side and lock rings by hammering, striking, or forcing the components while the tire is pressurized.(9) Heat shall not be applied to an inflated wheel tire assembly.Mich.
