Propane Tank Leak Shuts Down Highway | Seattle News

A massive 500-gallon propane tank leaked on Tuesday night in South Hill, forcing State Route 161 to shut down as crews raced to contain the dangerous situation. A driver spotted the hissing gas around 6:40 PM and alerted authorities. Firefighters set up a 330-foot safety zone and executed a controlled flaring operation to safely burn off the propane. Officials suspect the tank’s relief valve may have been tampered with, and investigators are now working to determine the exact cause. The tank will be fully drained before further analysis can begin. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
