Hand-Arm Vibration

Hand-arm vibration can cause a range of conditions collectively known as hand-arm vibration syndrome (HAVS), as well as specific diseases such as carpal tunnel syndrome.

Hand-arm vibration is vibration that is transmitted from work processes into the operators’ hands and arms. Jobs requiring regular and frequent use of vibrating tools and equipment as well as handling of vibrating materials are found in a wide range of industries, including construction, mining, quarries, motor vehicle manufacture and repair, etc. Moreover, there are hundreds of different types of handheld power tools and equipment that can cause ill health from vibration. Some of the more common tools are: chainsaws, concrete breakers, hammer drills, handheld grinders, and impact drills.

High frequency vibration is considered one of the principal pathogens for causing circulatory dysfunction in the extremities. Additionally, vibration affects tendons, muscles, joints, and nerves. Damage to either the muscles or nerves that control blood flow contribute to muscle fatigue as well as Raynaud's phenomenon. Symptoms induced by occupational vibration may gradually get worse if exposures continue, therefore it is extremely important to recognize the signs and symptoms early.

Although significant advances have been made in reducing tool vibration, preventative measures to reduce this hazard are still necessary. The following are recommended to limit the amount of hand-arm vibration exposure,

  • Engineering controls, Ex. anti-vibration tools
  • Good work practices, Ex. using only well maintained and properly operating tools
  • Use of personal protective clothing and equipment, Ex. anti-vibration gloves
  • Administrative controls Ex. limit total daily use or schedule more frequent breaks
