Gas leak closed Haynes Ave.
When a tanker truck containing a mixture of LPG and butane gasses pulled into the Haynes Ave. Town Pump Saturday afternoon, a release valve functioned properly to release excess pressure but then malfunctioned, staying open. The heavy nature of the two gasses causes them to stay low on the ground and slowly spread out. To prevent the spreading gas from finding an ignition source, Miles City's emergency services were called in. The fire department positioned the truck with the biggest deck gun to spray water on the truck's tank as Miles City Police, Custer County Sheriff and C.O.P.S. personnel shut down Haynes Ave. and evacuated the surrounding buildings.
As the water cooled down the truck, it was determined that the problem was cause by the tank having the wrong release valve for the mixture of gasses inside. The truck company was contacted and a tanker with the proper valve was sent to Miles City. Once the water had cooled the tank down, the valve closed properly stopping the gas leak. Then Miles City fire personnel escorted the tanker truck out of town to a near by gravel pit. Here the gas was safely transferred into the waiting tanker with the proper valve.
The leak had Haynes Ave. and the surrounding businesses closed for just over two hours. Fire chief Dale Berg said that any of the businesses effected by the evacuation can contact the fire station and obtain a copy of the incident report if needed for for insurance or any other reasons. Quick reporting and response by all the emergency personnel involved, kept bystanders at a safe distance as they prevented the leak from becoming an explosive disaster.
