Tucson firefighters quickly extinguished a fire in a vacant warehouse after a sprinkler system helped limit damage to the 105-year-old brick and timber structure.
A passing motorist called 911 after seeing smoke coming from around doors of the two-story Steinfeld Warehouse.
A total of 49 firefighters responded because of the size and construction type of the building.
The fire Sunday caused an estimated $20,000 damage to wood flooring
Fire officials say the fire was human caused and that someone had been inside before fighters arrived.
