Highway Overturned Propane Tanker

SEATTLE – On Monday, February 28, 2017, at 10:12 a.m., firefighters were dispatched to the area of Interstate 5 and Interstate 90 for a traffic incident that involved a 10,000-gallon propane semi-truck.

Two other vehicles were involved in the incident with the semi-truck causing it to roll-over onto the highway. Firefighters extricated the driver of the tanker and transported him to Harborview Medical Center with minor injuries. Two additional patients were also transported for evaluation.

The Seattle Fire Department (SFD) deployed specialty units to ensure the tanker was safely and properly moved. SFD’s Hazardous Materials (HazMat) unit investigated contents of the rolled-over tanker that was blocking the highway. They continued to check for hazardous material throughout the incident and ensured any potential hazard was contained. A second tank truck was brought to the scene to off-load the propane prior to lifting the damaged tanker off the highway. Seattle Fire Department’s Rescue 1 Company that specializes in technical rescues and operations assisted in the procedure, while HazMat remained on scene to monitor any leakages throughout the process.

A unified command was established in conjunction with the Seattle Police Department, Washington State Patrol, and Washington Department of Transportation for this incident. Liaisons from the Washington Department of Energy and Natural Response Corporation were also on scene to assist.

The City of Seattle activated the Emergency Operations Command and Joint Information Center to support operations surrounding this event until 7:05 p.m.
