Firefighters will spent 24 hours at the scene of a building fire in Holmfield.
Crews were called to Press Cut Machinery on Drakes Industrial Estate on Shay Lane at 1.15pm on Sunday after reports of a fire.
The fire started in an external storage shed and involved a flat back truck, before the fire spread to the main building which is used as an engineering shed.
Fire fighters say the main building was five per cent involved in fire.
The building was evacuated, with workers taken to North Bridge Leisure Centre in Halifax, because of the presence of acetylene gas cylinders.
Roads were closed for a short while and it was feared that some homes may have to be evacuated, but that was not deemed necessary.
Jets and ground monitors were used to tackle the fire, which was extinguished at 2.25pm.
Halifax and Illingworth crews attended.
Nobody was hurt.
