CHEEKTOWAGA, N.Y. -- A laser machine caused a small fire Wednesday morning at a metal shop on Cayuga Road in Cheektowaga.
Aluminum and carbon collected on a tray that collects dust, and firefighters say when those two mix in a dry environment, they can ignite.
By the time fire crews arrived around 7:30 a.m., workers had already knocked down the flames with extinguishers.
No one was injured.
