A hazmat team was called as a precaution in a two-alarm fire early Sunday morning at a Town of Tonawanda chemical plant.
Smoke was reported at about 1:30 a.m. on the second floor of the FMC plant on Sawyer Avenue, where firefighters found a machine on fire.
The machine contained a hazardous material known as ammonium persulfate, which is capable of intensifying a fire.
FMC, a worldwide company based in Philadelphia, produces industrial chemicals at the Tonawanda plant.
One firefighter suffered burns to his hand in battling the blaze and was taken by ambulance to Erie County Medical Center.
