One man is in hospital and four others have been treated at the scene of an explosion in Peterhead.
A silo at the ASCO supply base in the South Bay area of the town, operated by a third-party tenant, ruptured, leading to the loss of about 3,000 barrels of calcium chloride brine, a non-toxic product used in the oil and gas drilling process.
A contractor operating on behalf of the tenant was injured and taken to hospital as a precaution, the company said in a statement.
