Join Wellington Occupational Hygienist Christine de Klerk who will give an overview of both hand-arm vibration (HAV) and whole-body vibration (WBV). Human vibration is the effect of mechanical vibration on the body. In some cases, vibration can be unpleasant or even damaging to the bodily systems. Exposure to too much vibration may result in both acute and chronic injuries to the body. Excessive exposure to hand-arm vibration (HAV) from using hand-held power tools may result in the onset of conditions such as white finger, carpal tunnel syndrome, muscle joint damage in the hands and arms and sensory nerve damage. Excessive exposure to whole-body vibration (WBV) from using poorly designed or maintained machinery and driving surfaces my result in health effects such as lower back pain, varicose veins and heart conditions, bone damage, reproductive system damage, motion sickness and impaired vision and / or balance.
