5 injured in propane blast at Edmonds wastewater treatment plant

Five construction workers were hospitalized after a
propane tank explosion at a wastewater treatment plant in
Edmonds.

Crews were loading a 1,000 gallon propane tank onto the
back of a flatbed truck to be removed from the site,
according to Leslie Hynes, Public Information Officer with
Snohomish County Fire District 1.

“The truck driver said the load got shifted and he thinks
a valve got sheared off and that caused the 300 gallons
remaining inside the propane tank to be expelled,” Hynes
said.

The driver reportedly warned everybody to get away prior
to the explosion at the treatment plant on Picnic Point
Road. The truck was destroyed and two other buildings
damaged at the construction site.

The five injured workers were transported to Harborview
Medical Center with what initial reports call serious burn
injuries.

The Picnic
Point Wastewater Treatment Plant in Edmonds is located
near the Picnic Point Elementary School.
