A two-alarm commercial structure fire in downtown Olympia this morning burned for several hours, with concern over nearly propane tanks and a related delivery truck.

After getting the flames under control, the truck was driven away from the scene as the fire was knocked out. The main building was a total loss, including two fuel oil delivery trucks and two other vehicles inside the structure. A small tea wholesaler and a wood shop contained inside the building were also destroyed.

Fire department officials say there was no fire alarm system or fire sprinklers in the building, which was built before 1920 as part of a lumber mill. It has housed a number of different tenants over the years, most recently serving as a storage warehouse for a local fuel company.

Some firefighters will be on the scene most of today, along with inspectors, city building officials and representatives of the building owner or operators. Preliminary estimates of the losses are $350,000 for the structure and $500,000 for the contents.

At the peak, approximately 35 firefighters were on the scene, including those from City of Tumwater and Thurston County Fire Districts 6, 8 and 9. There were no injuries reported.
