SEMI-ROLLOVER, POTENTIAL CHEMICAL LEAK
UPDATE: 2:39 p.m. The Department of Ecology is sending a spill response crew from Spokane to assist. Estimated time of arrival is unknown.
1:35 p.m. | SPANISH PRAIRIE ROAD NEAR US-395
First responders are enforcing a 1/4 mile perimeter around the scene of an overturned semi transporting a trailer of pressurized Sulfur Dioxide.
The truck rolled off the narrow shoulder of Spanish Prairie Road half an hour ago and is upside down in a ditch one mile north of Colville.
Sulfur Dioxide is an industrial chemical used in winemaking, among other things. The Center for Disease Control (CDC) classifies Sulfur Dioxide as "immediately dangerous to life and health."
That said, the gas is not flammable and rarely fatal, due to the acrid smell and horrible sensation it causes in victims, which inspires those who breathe it to "run for their lives" according to the CDC.
Spanish Prairie Road is closed in both directions just east of its intersection with US-395.
This is a breaking news story and will be updated.
The truck rolled over into a roadside ditch and is resting upside down.
