Emergency services say the gas leak at the Ineos petrochemical site in Grangemouth has been contained.
The major incident was reported at 12.15pm today following a gas leak inside the refinery’s Kinneil Gas manufacturing plant which forced staff to be evacuated and a number of surrounding roads to be closed off to vehicles and pedestrians.
Residents as far away as the Braes area say a loud alarm sounded out from the plant which caused concern about public safety.
Falkirk Council says it was advised by the emergency services to keep local schoolchildren in buildings during the lunchtime break as a precaution, while Falkirk Football Club also closed its club shop due to the incident.
The Scottish Fire and Rescue Service, which led the multi-agency response including ambulance and the council, had eight fire appliances on the scene.
Police Scotland Superintendent Brian Auld confirmed “the incident has been contained on site” and expert personnel are in attendance, and said it was now safe for the public to “go about their normal business”.
