Vibration exposure at work can lead to discomfort in the hands and arms due to vascular and nerve damage. Hand Arm Vibration Syndrome (HAVS) caused by exposure to vibration at work is preventable, but once the damage is done it is permanent. Vibration damage can manifest itself as Raynaud’s syndrome, paresthesias and carpal tunnel syndrome. Carpenters, masons and construction workers are the most exposed occupational groups. There, almost 70% have been exposed to vibrating, hand-held tools for at least a quarter of their working time.
