An early-morning warehouse fire was extinguished quickly by Pasco fire crews, limiting damage to the 25,000 square-foot building, officials said.
Pasco firefighters were called to 506 S. Main at 2:15 a.m. and found moderate smoke throughout the building, said Capt. Dave Hare.
"Crews went in and were able to locate the fire within a couple of minutes," he said. "They made a pretty aggressive offensive interior attack and were able to contain the fire to the area of origin."
The fire appeared to have started on the second floor around the heating and air conditioning system, but the cause remains undetermined, Hare said.
Thirty-one firefighters responded to the blaze from Pasco, Kennewick and Richland fire departments and Franklin Fire District 3.
"We've been working real hard with our neighboring fire departments and this morning is a real good example of the training we've been doing with each other," Hare said Friday. "Everything seemed to fit together seamlessly. ... It was really good to have that extra help."
Pasco crews remained on scene for nearly three hours.
Damages are estimated around $40,000-$60,000.
