Firefighters tackle blaze in a large container next to a quarry near St Osyth.

A crew from Clacton plus Essex County Fire and Rescue Service’s off-road Pinzgauer appliance fought the blaze at Martin’s Farm.

The fire has taken hold in a container measuring 40ft by 10ft, and crews on scene report it is 25% alight.

The brigade was first called to the incident at 4.42pm, and are still on scene.

The contents of the container are unknown.

Crews had extinguished the blaze by 8.50pm, but returned the next morning to ensure the scene remained cool.
