Occupational vibration

Two types of occupational vibration that affect eight to 10 million U.S. employees can cause severe injuries. Segmental vibration, which occurs from vibrating pneumatic, electric, hydraulic or gasoline-powered hand tools, leads to disorders of the upper limbs. Whole body vibration, transmitted from the seats or platforms of vehicles, can cause a loss of vehicle control and musculoskeletal disorders of the spinal system.

Segmental vibration can be controlled by the use of low-vibration tools and proper tool upkeep. Employers must provide suitable equipment for employees to use and maintain it correctly.

Whole body vibration can be controlled by:

• using vehicles with suspension systems that minimize vibration
• using air-ride seats
• using good work practices, including allowing workers to take rest breaks and not lift objects after prolonged exposure to vibrations
• making workers aware of the signs and symptoms of whole body vibration back problems and the need to see safety mangers and health care providers if the symptoms occur
