Risk of explosion after farm fire

An exclusion zone has been set up around a farm workshop in Essex which has been badly damaged by fire.

Nine fire crews from Essex and London were called to Goatwood Lane at Navestock, Romford, at 0630.

Efforts to extinguish the 50m (164 ft) by 25m (82 ft) building were hampered by a lack of water to pump onto it.

Although the fire was put out within three hours, a cordon is expected to remain in place until Monday morning because a cylinders of gas were inside.

The building was used to store agricultural equipment, and propane and acetylene gas cylinders were also kept on the site.

An investigation into the cause of the fire will be carried out, but will not commence for 24 hours.
