Washington potato factory fire prompts evacuation over ammonia explosion fears

The Grant County Sheriff’s Office issued the "GO NOW" notice for all residents living west of Road U-SE and south of SR170 in Warden, Wash.

A fire at a potato plant in Eastern Washington on Thursday night prompted authorities to issue a Level 3 evacuation order due to the risk of an ammonia explosion.

The Grant County Sheriff’s Office issued the "GO NOW" notice for all residents living west of Road U-SE and south of Highway 170 in Warden, Wash., before 9 p.m. PT as the fire threatened an ammonia tank inside the Washington Potato Company.

"This Level 3 notice means you should leave the area now. Do not delay," the sheriff’s department said in the alert. "Law enforcement officers will go door-to-door to notify persons in the Level 3 area."

The sheriff’s department said emergency responders might not be able to help those who decide to stay.

PIO says fire was reported to have started in a dehydration unit at the Washington Potato Co. Building expected to be 'total loss,'" he tweeted.
