After battling a fire at a flea market, Seymour crews were called out to a second fire around 4:30 Saturday morning.
The fire department was still working on hot spots at the first fire when crews were called out to East Tennessee Wood Products on Sevierville Road.
Officials said the flames appeared to have sparked in a sawdust hopper on the property, which is located across the street from the fire station.
Crews were able to respond quickly due to the location, but had to call in extra help from Blount County to battle the flames.
No injuries were reported.
Several pets died in the flea market Friday evening.
Both fires remain under investigation.
