WorkplaceTesting explains Hand-Arm Vibration Syndrome (HAVS)

Hand-arm vibration syndrome is a serious concern in the workplace because it can be caused by working conditions and drastically alter a worker's ability to complete job tasks. Symptoms of hand-arm vibration include, numbness, tingling, and can even cause the fingers to turn white in color in some cases. The color change specifically occurs if there is a disruption in the blood flow to the fingers. Over time these symptoms can also cause muscle aches and pain. The continual exposure to the vibration of tools or machines causes an interruption of the nerve and blood flow to the hand. This is generally caused only after many years of exposure. In most case 10 years or more.
