n.
Single-Piece Wheel.
A vehicle consisting of one part, designed to hold the tire on the wheel when the tire is inflated.
o.
Trajectory.
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 air blast 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 (Figure 1).
p.
Wheel.
That portion of the 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).
3.
Employee Training.
a.
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.
b.
The employer shall ensure 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 steps 6 and 7 of this section.
c.
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.
d.
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 ensure that the employee is instructed concerning the contents of the charts
and rim manual in a manner which the employee is able to understand. The employer shall ensure that each employee
demonstrates and maintains the ability to service rim wheels safety, including performance of the following tasks:
(1) Demounting of tires (including deflation);
(2) Inspection and identification of the rim wheel components;
(3) Mounting of tires (including inflation with a restraining device or other safeguard required by this
work package);
(4) Use of the restraining device or barrier, and other equipment required by this work package;
(5) Handling of rim wheels;
(6) Inflation of the tire when a single-piece rim wheel is mounted on a vehicle;
(7) 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;
(8) Installation and removal of rim wheels.
e.
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 ensure that each employee maintains his or her proficiency.
4.
Tire Servicing Equipment.
a.
The employer shall furnish a restraining device for inflating tires on multi-piece wheels.
b.
The employer shall provide a restraining device or barrier for inflating tires on single-piece wheels.
c.
Restraining devices and barriers shall comply with the following requirements:
(1) 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.
(2) 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.
