Firefighters responded about 7:15 a.m. to Precision Machine Works, Inc., in the 2000 block of Puyallup Avenue and saw smoke coming from the structure’s eaves.
All employees were able to escape and warned firefighters that the blaze started on a deburring machine, which hosts several hoppers and collects metal shavings.
The shavings were titanium, which is water reactive, meaning crews had to use dry chemical extinguishers to douse the flames.
“What normally would have been a pretty quick knockdown took 10 or 15 minutes,” firefighter Joe Meinecke said.
No injuries were reported. Damages are estimated at $55,000.
