// Hand-arm vibration and whole-body vibration

Workplace Vibration

Mechanical vibrations at work can expose workers to hand-arm vibration (HAV) and/or whole-body vibration (WBV). HAV exposure is commonly experienced through hand-held tools such as chainsaws, grinders, and drills, while WBV is commonly transferred through the seats of mobile plant and motorised equipment. Excessive exposure to vibration can cause permanent damage to a person’s fingers, hands, spine, and internal organs. Hand-Arm Vibration Syndrome (HAVS) can cause loss of grip strength and the inability to do fine work, while cold conditions can trigger painful finger blanching attacks. HAVS is preventable, however, once the damage is done it is permanent.

The Control of Vibration at Work Regulations sets out the rights and responsibilities of employees and employers relating to occupational vibration exposure. There are different exposure action values and limit values relating to exposure from both HAV and WBV, which if exceeded, trigger specific requirements and actions to be followed by employers and employees.
