Employees at a castings plant had to be evacuated after a filtration unit in one of their machines caught fire.
A total of 25 employees at Newby Steel Castings, in Smethwick, left the premises once the blaze started yesterday.
They were already outside the factory unit when two fire crews from Smethwick and Handsworth stations arrived.
Crews were called to the scene, in Cornwall Road, at around 2.30pm.
Flames were isolated to one of the machines after a dust filter set alight.
Firefighter Chris Mason, from Smethwick station, said: "We got access to the machine and opened it up, extinguished the fire, and checked to make sure it was out."
The fire crews left the scene around two hours later, and left the machine with engineers at the plant.
The firm's technical director, Steven Smith, said "It was not a major fire and it cost us around an hour and a half in the end.
"We evacuated staff as a precaution until the fire service arrived.
"Once it was extinguished we went back to work.
"Repairs will have to be carried on the filter but it will in not way affect our work."
