Understanding the Impact of Workplace Vibration

Workers in a diverse range of industries are exposed to occupational vibrations on a daily basis mobile view

Workers in a wide-range of industries spend part of their day exposed to heavy vibration. This may not seem like a problem but repeated exposure to high levels of vibration can cause injuries to workers. Excessive levels of vibration over time can cause disruption to muscular, nervous and vascular systems that results in numbness, nerve and/or soft tissue damage and fatigue. Many employers are unaware of the risks of occupational vibration until a worker reports side effects.

Two Types of Vibration

There are two different types of vibration that can cause problems: hand-arm vibration and whole-body vibration. Hand-arm vibration is typically associated with occupations that require operating hand-held power equipment such as sanders, saws and impact drills. Whole-body vibration is associated with truck and bus drivers, heavy equipment operators and aircraft pilots.

Controlling Occupational Vibration

Once an occupational vibration hazard is identified, employers can use a variety of strategies to reduce the likelihood of injuries, including eliminating or reducing the hazard and educating workers about the side effects.

Hand-arm vibration can be reduced by:

  • Replacing current tools with low-vibration tools designed to reduce acceleration levels and cushion workers’ hands
  • Using anti-vibration gloves designed with state-of-the-art materials
  • Implementing regularly scheduled breaks to avoid constant exposure
  • Performing regular maintenance on machinery to prevent excessive vibration
  • Screening workers regularly through a specialized hand-arm vibration medical exam
  • Measuring and monitoring the vibration of tools so that tools with increasing accelerating levels from age and wear can be repaired or replaced

Whole-body vibration can be reduced by:

  • Installing reduced-vibration or suspended seats to isolate drivers from the vibration of trucks and other heavy equipment
  • Isolating vibrating equipment from surfaces where workers are stationed
