Hand Arm Vibration and Whole Body Vibration
Overexposure to vibration from power tools, machinery and vehicles can impact the human body in several ways and cause permanent damage. The UK Health and Safety Executive estimates there could be between 2 million people at risk of suffering from Hand Arm Vibration Syndrome (HAVS, or Vibration White Finger); a painful, disabling and irreversible condition affecting blood vessels, nerves and joints which over time can stop people from carrying out normal everyday tasks.Vibration transmitted to drivers of tractors, forklift trucks and other plant machinery are also at risk from Whole Body Vibration (WBV) and back pain; this occurs where shocks from driving over uneven ground or bumps travel through the vehicle into the driver.
The Control of Vibration at Work Regulations 2005 requires companies to assess the risk of injury from vibratory tools in the workplace. The two main elements you must monitor are vibration exposure level and vibration exposure time. According to the HSE:
Vibration Exposure Level is the vibration magnitude level emitted from the equipment your workers use, and therefore is the level that your workers are exposed to.
Exposure Time is the length of time that workers are being exposed to vibration.
Only when you are aware of the two elements above are you able to assess and control the level of vibration exposure to your workers. The vibration regulations implement Action and Limit Values for you to work to. These are:
Exposure Action Value of 2.5 m/s2 A(8) at which employers should introduce measures in order to reduce exposure
Exposure Limit Value of 5.0 m/s2 A(8) which should not be exceeded
Tools that can cause Hand Arm Vibration Syndrome (HAVS) include:
- concrete breakers, concrete pokers.
- sanders, grinders, disc cutters.
- hammer drills.
- chipping hammers.
- chainsaws, brush cutters, hedge trimmers.
- powered mowers.
- scabblers or needle guns.
