Fire crews were called to an industrial site in Norcroft Street, in the Listerhills area of Bradford, shortly before 11:30am yesterday.
This was initially reported as a car fire in a building, however, on arrival crews found that this was a multiple occupancy premise.
The fire was contained within a repair garage, inside which were over a dozen vehicles.
Eight fire pumps plus support alliances attended the scene; 70 fire fighters tackled the blaze using one ariel ladder platform, seven ground monitors and hand held jets.
District Commander for Bradford, Martin Speed said, “The fire was discovered by mechanic working within the garage who then raised the alarm.
Before the fire services arrival they attempted to put the fire out using handheld extinguishers but were unable to do so. Fortunately no-one was hurt.”
On arrival they discovered the garage workers attempting remove vehicles from the site, however a handful of the cars had been destroyed by the fire.
The fire has also significantly damaged the roof of the garage; however crews managed to stop it from spreading to adjoining properties, which have escaped with only smoke damage.
Around 30 people from neighbouring business premises were evacuated and Thornton Road and Listerhills were closed.
DC Speed added “The smoke from this fire could be seen for miles; however our crews have worked quickly to get the blaze under control and prevent further spreading.”
A full investigation into the cause will be carried out in due course.
