Hand-Arm Vibration Syndrome (HAV’s) Testing

An important health and safety issue facing many heavy-industry and construction workers is the risk of vibration injury from certain handheld tools that leads to a condition called hand-arm vibration syndrome (HAVS).

Wrightway Health provides HAV’s testing as part of our comprehensive Health Surveillane programme.
The Control of Vibrations at work regulations 2005 define a daily exposure action value and a daily exposure limit value for hand transmitted vibration (HTV). Health surveillance must take place when:

  • Employees are regularly exposed to HTV above the action value of 2.5 minutes over a standard 8 hour day.
  • If an employee is occasionally exposed to HTV above the action value and the risk assessment identifies that this exposure may pose a risk to health
  • If an employee has a previous diagnosis of HAVS.

The tools most likely to create risk include chainsaws, grinders, jack-hammers, floor polishers and impact drills. The occupations that involve regular and frequent exposure to vibration include but are not limited to:

  • Construction
  • Forestry
  • Automotive industry
  • Ship building and repair
  • Foundries

HAVS is often a painful medical condition that can impact on the everyday lives of those affected by it. HAVS symptoms include:

  • Numbness and tingling in the fingers
  • Reduced sense of touch and temperature
  • Carpal Tunnel Syndrome
  • Blanching of the fingers, sometimes known as vibration white finger

The objective of health surveillance for HAVS is to safeguard the health of employees and ensure the effectiveness of a company’s existing control measures.
