Measurement Axes of WBV in the Human Body, Source: ISO 2631-1
Whole Body Vibration (WBV), especially when it becomes a chronic condition, is suspected to cause adverse health effects such as fatigue, lower back pain, vision problems, interference with or irritation to the lungs, abdomen, or bladder, and adverse effects to the digestive, and urinary systems. Other issues include:
- Back injuries and issues (resulting from constant impact on the driver for up to 8 hours per day) are significant symptomatic effect of the WBV phenomenon – one that can contribute to lessened on-the-job productivity and worker focus.
- WBV is also a major source of lost time in occupational environments, especially where drivers operate commercial, industrial and heavy equipment/OTR vehicles.
- About 8 million U.S. workers have occupational vibration exposure. Of these, an estimated 6.8 million are exposed to WBV and the remainder is exposed to Hand-Arm Vibration (HAV) (Source: Bruce, Bommer & Moritz, 2003; ACGIH, 2001)
