Hand–arm vibration (HAV) arises from the use of powered tools and equipment that transmit vibration into the hands and arms. Prolonged and repeated exposure can lead to serious and permanent health conditions, including vibration white finger, loss of sensation, numbness, and pain. Collectively, these conditions are known as Hand–Arm Vibration Syndrome (HAVS).

Employer Responsibilities

Employers have a legal duty to ensure that employees are not exposed to vibration levels above the Exposure Limit Value (ELV).

• If the Exposure Action Value (EAV) is reached or exceeded, employers must take steps to reduce exposure as far as reasonably practicable.
• If the Exposure Limit Value (ELV) is exceeded, immediate action must be taken to reduce exposure below the limit.

Effective monitoring and control are essential to meeting these obligations and protecting employee health.
