A serious fire broke out on an industrial estate in Worcestershire involving a number of gas cylinders.
The fire began in a factory on the Racecourse Industrial Estate in Pershore, at 0620 BST on Sunday.
Eight crews tackled the fire and a 200m (656ft) exclusion zone was erected due to the risk of the acetylene, nitrogen and oxygen cylinders exploding.
The Environment Agency attended to ensure run off water did not pollute the near-by brook.
Hereford and Worcester Fire and Rescue Service said it was a "serious" fire that involved a 50m by 75m (164ft by 246ft) industrial unit.
