A rim wheel is the component assembly of wheel (either multi-piece or single-piece), tire and tube, plus other components. A single-piece wheel is the component of the assembly used to hold the tire, form part of the air chamber (with tubeless tires), and provide the means of attachment of the assembly to the vehicle axle. A multi-piece wheel is a vehicle wheel consisting of two or more parts, one of which is a side or locking ring that holds the tire and other components on the rim wheel by interlocking the components when the tire is inflated. Why Are Safety Standards Needed for Servicing Single-Piece and Multi-Piece Rim Wheels?
Approximately 322,000 employees in more than 100,000 workplaces service large vehicle tires that are mounted on either multi-piece or single-piece wheels. In 1984, OSHA amended the safety standard for servicing multi-piece rim wheels (29 Code of Federal Regulations 1910.177) to include requirements for the safe servicing of single-piece rim wheels used on large trucks, trailers, buses, and off-road machines. OSHA's standard does not apply to the servicing of rim wheels utilizing automobile tires or to trucks designated “LT” (light trucks). The amended safety standard for servicing single-piece and multi-piece rim wheels has four major requirements: (1) training for all tire servicing employees; (2) the use of industry-accepted procedures that minimize the potential for employee injury; (3) the use of proper equipment such as clip-on chucks, restraining devices or barriers to retain the wheel components in the event of an incident during the inflation of tires; and (4) the use of compatible components. There has been a more than 70-percent reduction in multi-piece rim wheel servicing injuries since the original standard was issued in 1980 -- based on a review of the record of multi-piece rim wheel accidents investigated by OSHA. Similar results have been experienced with the regulation of single-piece rim wheel servicing where workers also face a significant risk of serious injury or death. What Are The Hazards of Working With These Large Vehicle Tires?
The principal difference between accidents involving single-piece rim wheels and those involving multi-piece rim wheels is the effect of the sudden release of the pressurized air contained in a single-piece rim wheel. Single-piece rim wheel accidents occur when the pressurized air contained in the tire is suddenly released, either by the bead breaking or by the bead slipping over the rim flange. The principal hazards involve pressurized air which, once released, can either hurl an employee across the shop if the employee is in close proximity to the rim wheel and within the trajectory, or can propel the rim wheel across the workplace and into a worker. The trajectory of the air or rim wheel is any potential path or route (basically along the axis of the rim wheel) that a rim wheel component may travel during an explosive separation, or the area into which the air blast from a single-piece rim wheel may be released. In a multi-piece rim wheel accident, the wheel components separate and are released from the rim wheel with violent force. The severity of the hazard is related not only to the air pressure but also to the air volume. What Are Safe Operating Procedures for Single-Piece Rim Wheels?
Employees must be instructed in and must use the following steps for safe operating procedures with single-piece wheels:
What Are Safe Operating Procedures for Multi-Piece Rim Wheels?
Employers must instruct employees to use the following steps for safe operating procedures:
What Servicing Equipment Must Be Supplied?
The restraining device can be a cage, rack, or an assemblage of bars and other parts that will constrain all rim wheel components during an explosive separation of the multi-piece wheel or during the sudden release of the contained air of a single-piece rim wheel. A barrier can be 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 contained air. Each barrier or restraining device must be able to withstand the maximum force of an explosive rim wheel separation or release of the pressurized air occurring at 150 percent of the maximum tire specification pressure for the rim wheel being serviced. Restraining devices showing any of the following defects must be immediately removed from service:
Current charts or a rim manual containing instructions for the types of wheels being serviced must be available in the service area, including a mobile service unit. Only tools that are recommended in the rim manual may be used for the type of wheel being serviced. The employer must also supply air line equipment with a clip-on chuck with sufficient length of hose between the chuck and in-line valve or regulator to allow the employee to stand outside the trajectory, as well as an in-line valve with a pressure gauge or a presettable regulator. The size (bead diameter and tire/wheel width) and type of both the tire and wheel must be checked for compatibility prior to assembly of the rim wheel. Mismatching of half sizes such as 16-inch (40.6 centimeters) and 16.5 inch (42 centimeters) tires and wheels must be avoided. Multi-piece wheel components must not be interchanged except as indicated in the applicable charts or rim manuals. Multi-piece wheel components and single-piece wheels must be inspected prior to assembly. Any wheel or wheel component that is bent out of shape, pitted from corrosion, broken, or cracked must be marked or tagged “unserviceable” and removed from the service area. Damaged or leaky valves must be replaced. Rim flanges, rim gutters, rings, and the bead-seating areas of wheels must be free of any dirt, surface rust, scale, or loose or flaked rubber buildup prior to tire mounting and inflation. What Training Is Required?
The employer must provide a program to train all employees who service rim wheels in the hazards involved and the safety procedures to be followed. The employer must assure that no employee services any rim wheel unless the worker has been instructed in correct procedures of mounting, demounting, and other servicing activities, and the safe operating precautions for the type of wheel being serviced. At a minimum, the training program must include the requirements of the OSHA standard and the information in the manufacturers' rim manuals, or the OSHA charts. Charts are available from OSHA regional, area, or national offices. The instruction must be conducted in an understandable way. Employees who are unable to read the charts or rim manuals must be trained in the subject matter. The employer must assure that each worker demonstrates and then maintains the ability to service rim wheels safely by correctly performing the following tasks:
How Can OSHA Help?
OSHA has a variety of programs to assist employers and employees in achieving a safe and healthful workplace. These include voluntary safety and health program management guidelines, free onsite consultations, and training and education. Safety and Health Program Management Guidelines Effective management of worker safety and health protection is a decisive factor in reducing the extent and severity of work-related injuries and illnesses and their related costs. To assist employers and employees in developing effective safety and health programs, OSHA published recommended Safety and Health Program Management Guidelines in the January 26, 1989, Federal Register (54 FR(18) pp. 3908-3916). These voluntary guidelines apply to all places of employment covered by OSHA. The guidelines identify four general elements that are critical to the development of a successful safety and health management program:
Free Onsite Consultation Free, onsite safety and health consultation services are available to employers in all states who want help in establishing and maintaining a safe and healthful workplace. The service is largely funded by OSHA. Primarily developed for smaller employers with more hazardous operations, the consultation service is delivered by state governments employing professional safety consultants and health consultants. Comprehensive assistance includes an appraisal of all mechanical systems, physical work practices, and environmental hazards of the workplace and all aspects of the employer's present job safety and health program. This program is completely separate from OSHA inspections. No penalties are proposed or citations issued for any safety and health problems identified by the consultants. Also, the service is confidential. For more information concerning consultation services, see the list of consultation projects at the end of this publication. Training and Education OSHA's area offices offer a variety of informational services, such as publications, audiovisual aids, technical advice, and speakers for special engagements. OSHA's Training Institute in Des Plaines, IL, provides basic and advanced courses in safety and health for federal and state compliance officers, state consultants, federal agency personnel, and private sector employers, employees, and their representatives. OSHA also provides funds to nonprofit organizations, through grants, to conduct workplace training and education in subjects where OSHA believes there is a lack of workplace training. Grants are awarded annually. Grant recipients are expected to contribute 20 percent of the total grant cost. For more information on grants, training, and education, contact the OSHA Training Institute, Office of Training and Education, 1555 Times Drive, Des Plaines, IL 60018, (847) 297-4810. Voluntary Protection Programs (VPP) OSHA's Voluntary Protection Programs recognize and promote effective safety and health program management. In the VPP, management, labor, and OSHA establish cooperative relationships at workplaces that have implemented strong programs. Sites approved for VPPs, Star, Merit, and Demonstration programs have met, and must continue to meet, rigorous participation standards. Benefits of VPP participation include improved employee motivation to work safely, leading to better quality and productivity; lost-workday case rates that generally are 60 percent to 80 percent below industry averages; reduced workers' compensation and other injury- and illness-related costs; positive community recognition and interaction; further improvement and revitalization of already good safety and health programs; and partnership with OSHA. For information about the VPP, contact the VPP Manager in your OSHA Regional Office, listed at the end of this publication. State Programs The Occupational Safety and Health Act of 1970 encourages states to develop and operate their own job safety and health plans. The states administering occupational safety and health programs through plans approved under section 18(b) of the Act must adopt standards and enforce requirements that are “at least as effective” as federal requirements. There are currently 25 state plans: 23 cover the private and public (state and local governments) sectors and 2 cover the public sector only. For more information on OSHA-approved state plans, see the list of states with approved plans at the end of this publication.
