Edmonds propane explosion causes $1M in damage

An accidental explosion at a wastewater facility near Edmonds on Thursday caused $1 million in damage to two buildings under construction.

 

The Snohomish County Fire Marshal's Office said the fire and explosion at the Alderwood Wastewater facility at 6315 Picnic Point Road was reported by workers there at 11 a.m.

 

Fire officials said propane vapors ignited while a contractor was lifting a 1,000-gallon propane tank onto a truck to remove it from the property.

As the tank, which had about 300 gallons of propane inside, was being placed onto the metal deck of the truck, a brass drain valve on its bottom broke off, releasing propane from under the tank.
