Cambs fire service deployed their chemical emergency procedure which they had only recently practised during an intensive training exercise in Peterborough.

On Wednesday morning shortly after 8.30am they were called to put that training to work as they entered Moy Park to join onsite specialists in isolating the leak.

As appeals went out to nearby residents to close their windows and shut their doors, fire crews entered the factory to contain the risk.

By 10am Cambs fire service announced the “area is no longer a threat to public safety”.

A spokesman for Moy Park said: “A small ammonia leak was detected from a piece of refrigeration equipment at the factory.

“The piece of equipment is located in a controlled environment within the site plant room.

“A well rehearsed incident plan was followed, the fire service was called to the factory and the leak was quickly contained.”

An ambulance spokesman said: “The eleven people that we assessed had inhaled some of the fumes.

“Thankfully their conditions weren’t thought to be serious and they didn’t require hospital treatment.”

Two crews from Wisbech, one crew from St Neots and a rescue vehicle from Dogsthorpe attended along with fire officers.
