MILLERSBURG -- Fire crews have controlled a zirconium fire that posed special challenges at a rare metals manufacturing plant in Millersburg.

Albany Fire Marshal Mike Trabue says crews responded Thursday to a building at ATI Wah Chang after a report of a combustible metals fire that was extending to a building. No one was injured.
Firefighters found several stainless steel containers of zirconium sponge on fire. Trabue says zirconium metal can react violently when it comes in contact with water so fire crews couldn't use that. With the help of Wah Chang workers outside the building, firefighters used special extinguishing powders and sand to control the fire.

At one point, Trabue says crews were pulled out of the building due to concerns that the roof might fail. The fire finally subsided enough that plant workers were able to remove the smoldering containers from the building.

About 40 firefighters from Albany and nearby Willamette Valley districts responded.

The cause of the fire is under investigation. There was no immediate damage estimate.

Cement smothers Prineville zirconium fire

Shovel sparks fierce fire; firm learned from previous blaze

POSTED: 12:20 PM PST November 27, 2012    UPDATED: 7:35 AM PST November 28, 2012 


PRINEVILLE, Ore. - A spark from a shovel ignited a fierce fire in a pit of flammable zirconium in an industrial area west of Prineville late Tuesday morning, officials said. The blaze sent up a tall smoke plume for hours, prompting authorities to keep students in doors and urge that anyone with respiratory problems do so as well, and report any symptoms to 911.

Matt Smith, chief of Crook County Fire and Rescue, said the fire was reported around 11:20 a.m. at EnviroTech Services, a business at the Prineville Freight Depot about three miles west of town. The 2-year-old facility makes road de-icer and dust control products, according to a 2010 article on its Website.

A hazardous materials team from SMAF Environmental was called in and began pouring dry cement onto the fire to smother it.

The smoke was called an "irritant" and not a significant health threat, though officials were advising people with breathing problems to stay indoors as a precaution.

Fire Marshal Casey Kump later said a spark from a shovel or scoop on a machine (not a hand shovel) ignited the pile of metal filings, sparking the fire and smoke that "drew a great deal of concern in town," but had begun to dissipate by late afternoon.

Kump said the fire department worked in close coordination with Crook County Emergency Management Director Dave Dethman, as well as the sheriff's office, health department, Pioneer Memorial Hospital and area schools, which kept students indoors.

No evacuations were enacted, he said, and no injuries reported.

The company makes de-icer, and "zirconium is a byproduct of their process," Smith said. "Zirconium, when it's dried in a form of metal filings, is highly flammable. If a spark or something is near it, it can catch fire."

The material is located in a "not incredibly deep" containment pit, the fire chief said, adding that "everything worked as it should have," in terms of isolating the fire in the pit and preventing more problems.

"We have had, in the last year, one other fire regarding zirconium, and we have had a fire involving an excavator," Smith said.

Fire officials say the company learned from a similar fire a year ago. After that incident, a pit was dug to hold the metal shavings of zirconium.

"The containment pit worked as it was supposed to, and the fire was contained to that," Smith said.

An Oregon OSHA official said they agency had not inspected the facility but will be looking into what happened, though a representative did not classify it as a formal investigation.

Smoke from the fire drifted toward Prineville, and an inversion also was in place Tuesday, so Smith said "what is wood smoke, what is this smoke and what's fog is hard to say."

Kump said, "If residents in the area feel that the smoke is causing medical or respiratory problems, they should call 911."

Zirconium fire at Wah Chang causes no injuries or monetary damage

At about 12:45 p.m. Wednesday, Albany firefighters responded to Wah Chang, 1600 Old Salem Road N.E., on a report that a mixer and conveyor were on fire inside building.

No one was hurt and no monetary damage was reported.

Smoke could be seen coming from the plant from half a mile away.

Zirconium metal fines caught fire, said Wanda Omdahl, Albany Fire Department spokeswoman. Fires involving the rare metal cannot be extinguished with water, she said.

“With rare metals you have to protect exposures and let it burn itself out,” Omdahl said. “It becomes explosive when you have water on it.”

A malfunctioning conveyor belt caused the zirconium to catch fire, she said.

The fire was initially called out as a first alarm, but quickly downgraded. An engine, a truck and a medic unit and about eight firefighers were on the scene.
