PORTLAND, Ore. (KOIN) — Firefighters are responding to a heavy pallet fire that has downed multiple power lines and is threatening a number of buildings near the Whitaker Ponds Natural Area in Northeast Portland.

According to a Portland Fire and Rescue post on X at 7:35 p.m., fire crews responded to "a large stack of pallets" on fire, with the flames extending to a tree and a home Thursday night.

Firefighters said they were taking defensive measures to ensure the flames did not ignite a large fuel storage tank on site.

Within 30 minutes, the fire was escalated to a second-alarm fire and then a third-alarm fire, officials said.

"Many buildings are being threatened by heavy fire. Multiple live power lines down," a follow-up post said.

By 8:21 p.m., PF&R said that Port of Portland fire crews were on the scene to assist, if needed, after the fire extended into "one of the of the metal clad buildings," with one structure collapsing. No injuries were reported.

Crews were also reportedly working with a "limited water supply." The Portland Water Bureau was also assisting in the effort. With the downed power lines, finite amount of water and need to protect "valuable equipment," fire crews were working to manage "competing priorities," officials said.

By 8:37 p.m., PF&R said the incident was "beginning to stabilize" and that they were starting rehabilitation rounds for the firefighters.
