WORKERS at a paint factory have been evacuated after an ammonia leak.

Firefighters from Cleckheaton and Dewsbury were called to P P G Architectural Coatings in Huddersfield Road, Birstall shortly after 9pm yesterday.

The leak from a storage container was spilling out on to the forecourt, said Cleckheaton Watch Commander Darren Haley.

Firefighters had to wear breathing apparatus to assess the incident and contain it.

He added: "Everyone had to be evacuated from the site but no one was hurt and we managed to contain the leak so there was no effect on the environment."

Firefighters were at the scene for three hours. P P G also called in its own safety specialists.
