Explosion 'due to fridge and gas'

The emergency services were called to the St Fergus terminal

An explosion at a gas terminal which sparked a major emergency services operation was caused by a leaking gas sample and a fridge.

The incident happened at the St Fergus gas terminal near Peterhead in Aberdeenshire on Tuesday.

Three people working nearby did not require hospital treatment.

Operators Total said gas leaked from a cylinder and ignited as a fridge cut in, causing a spark. The explosion blew out a window in the laboratory.

Total said it had been a "minor" explosion.

The Health and Safety Executive (HSE) has been informed.
