Hand-Arm vibration is a serious syndrome that affects many which is why it will be this week’s Toolbox Talk topic. Protecting workers from excessive hand-arm vibration is crucial as it can lead to debilitating symptoms known as hand-arm vibration syndrome (HAVS). Prolonged exposure may impair individuals’ well-being and work effectiveness. Implementing measures to minimise this exposure is vital for ensuring the health and safety of workers across industries.

Effects of Hand-arm Vibrations

  • Harm blood vessels, nerves, tendons, ligaments, muscles, and bones.
  • Tingling, numbness, fingertip sensitivity, finger pain, reduced dexterity, joint discomfort, worsened pain after warming hands.
  • Carpal tunnel syndrome (CTS), characterised by severe nerve pain in the palm, often worsening at night.
  • The consequences of hand-arm vibration are typically irreversible, causing persistent pain and diminishing quality of life.
  • Struggle with basic tasks like buttoning clothes or tying shoelaces.
  • Initial tingling in hands worsens with prolonged vibration exposure.
  • Construction tools that generate significant levels of vibration include:
    • road and concrete breakers
    • cut-off saws or disc cutters
    • power drills and chisels
    • plate vibrators and scribblers
    • concrete poker vibrators
    • hammer drills
    • chainsaws
    • needle guns
    • angle grinders
    • riveters

How to avoid excessive vibration exposure

  • Prioritise non-hand-held tools to minimise vibration; for instance, use excavator-mounted breakers instead of handheld ones.
  • Set and adhere to time limits for using vibrating tools to prevent overexposure.
  • Take regular breaks when using vibrating tools; warm hands and exercise fingers, especially in cold conditions.
  • Employ proper technique with hand-held tools to avoid excessive force; let the tool do the work.
  • Keep hands warm and dry with gloves, but note that anti-vibration gloves offer limited protection.
  • Report symptoms such as pins and needles promptly to your supervisor.

Hand-arm vibration is a significant occupational hazard that can lead to various health issues. It is essential for employers to implement effective measures to minimize exposure and for workers to use appropriate tools and techniques to reduce the risk of injury. By prioritizing awareness, prevention, and proper safety protocols, we can mitigate the impact of hand-arm vibration and promote safer working environments for all.
