Witham aluminium factory is evacuated in 'major blaze'
A factory building was evacuated after a "major blaze" spread from an extraction unit to the walls and roof.
The fire at Amtek Aluminium in Freebournes Road, Witham, started at about 04:00.
It was the 36th incident dealt with by crews during the 24-hour Fire Brigades' Union strike.
The fire was out by 06:30. A joint police and fire service investigation is under way into the cause of the fire.
A spokesman for the fire service said crews had to "work quickly" to prevent fire spreading because the 100m (328ft) by 50m (164ft) site was "made up of a number of smaller buildings all linked together".
