Puget Sound Energy crews plugged a major gas service line leak in SODO after it was ruptured this morning.
At 5:35 a.m. a 911 call came into dispatchers at the Fire Alarm Center reporting a major gas line break at 55 South Spokane Street. The first arriving company found a high-volume of gas leaking into the air. The break occurred just inches from a rolling door to a large industrial building. Firefighters evacuated the building. The exact cause of the leak is still under investigation.
Seattle Police officers shut down South Spokane Street from 1st Avenue South to East Marginal Way. Also the 1st Avenue South exit from the eastbound West Seattle Freeway was shut down as a precaution until the gas leak was plugged.
Burlington Northern train traffic was diverted from nearby tracks as a precaution.
As a precaution, firefighters extended a hose line to the gas leak location to be ready to extinguish any potential fires.
The Mobile Ventilation Unit, a large scale industrial sized fan, was brought in to clear out the natural gas from inside the building. The mobile unit can move 125,000 cubic-feet-per-minute (CFM). By comparison, a personal fan can normally move under 1000 CFM.
About an hour and fifteen minutes after the gas leak was reported, PSE crews plugged the gas line.
At 7:25 a.m. after PSE crews plugged the gas line, the 1st Avenue Exit was re-opened and Burlington Northern resumed train operations.
Westbound S Spokane Street was reopened to traffic however eastbound lanes are closed to allow PSE crews room to repair the gas line.
