FIRE crews spent three hours battling a blaze at an industrial workshop.
The fire was at Bibby Transmissions in Cannon Way, Dewsbury.
The workshop, which is at the rear of the main building, has been destroyed.
One person, thought to be a member of staff, was slightly injured.
Dewsbury firefigher Andrew Lindley said: "The workshop was full of industrial equipment and although it did not take us long to get the fire under control it did take a while to make the site totally safe.
"We are still not sure of the cause of the fire and investigators are going back to try and find out."
The blaze broke out at 4.20pm on Monday.
