Vibration

Hand-arm vibration is transmitted from construction work activity into the hands and arms when:

  • using hand held power tools, such as road breakers; 
  • using hand guided equipment such as a vibrating compactor; 
  • holding materials being processes by a machine. 

Construction workers are more likely to suffer permanent harm if contact with vibration is a regular and frequent part of their job.

Hand-arm vibration can cause a range of conditions called hand-arm vibration syndrome (HAVS).

The best known is vibration white finger (VWF), but vibration also links to specific diseases such as carpal tunnel.
