Hand Arm Vibration

A dosimeter is used for the measurement of hand arm vibration

Hand Arm Vibration (HAV) is a prevalent occupational health concern that affects workers exposed to vibrating tools and equipment. This condition can lead to serious health issues if not properly managed. Measurement and quantification of your HAV risk exposure can be achieved by performing a site wide HAV survey.

Causes of Hand Arm Vibration:

HAV occurs when a person is exposed to regular and frequent vibrations transmitted through hand-held tools and machinery. Common sources include grinders, chainsaws, pneumatic hammers and compactors. These vibrations can lead to damage in blood vessels, nerves, and joints, ultimately resulting in conditions like Hand Arm Vibration Syndrome (HAVS).

Risks and Health Implications:

Workers experiencing prolonged exposure to hand arm vibration face various health risks. HAVS manifests with symptoms like tingling, numbness, and pain in the fingers and hands. In advanced stages, it can lead to reduced dexterity, impaired grip strength, and even permanent disability. Additionally, individuals with HAVS are more susceptible to conditions like carpal tunnel syndrome.

Prevention Measures:

  1. Tool Selection and Maintenance:
    • Choose low-vibration tools and equipment.
    • Regularly inspect and maintain machinery to ensure optimal performance and reduce vibration levels.
  2. Personal Protective Equipment (PPE):
    • Provide workers with anti-vibration gloves to minimize direct contact with vibrating tools.
  3. Workplace Ergonomics:
    • Design workstations to minimize awkward postures and excessive force during tool operation.
  4. Training and Awareness:
    • Educate workers about the risks of HAV and proper tool usage techniques.
  5. Rotational Job Assignments:
    • Rotate tasks to limit prolonged exposure to vibrating tools.

Understanding hand arm vibration and its associated risks is crucial for maintaining a safe and healthy work environment. By understanding your workplace exposure risk, implementing prevention measures and providing proper training, employers can significantly reduce the incidence of HAV-related health issues among their workforce. Prioritizing the well-being of employees not only safeguards their health but also contributes to a more productive and efficient workplace.
