Hand arm vibration (HAVs) can cause tingling, pins and needles, numbness and pain in the affected persons’ hands.

The firm should have checked the exposure by workers to the vibrations from hand-held tools, potentially exposing the workforce to the risk of injury whilst working within the workshops.

A criminal investigation was launched and called against the company at Paisley Sheriff Court last week.

BA admitted it failed to carry out the legally required protocols between July 2005 and August 2012 at the British Airways Limited premises at Glasgow Airport and was fined £6,500.

A BA spokeswoman said: “We take our responsibility to our colleagues very seriously. As soon as the issue was identified we took immediate action to limit the time they use these tools.”
