Crash causes spill near Dinosaur


— A Friday night crash on Colorado Highway 64, about four miles east of Dinosaur in Rio Blanco County, resulted in the spill of hazardous material, the Colorado State Patrol reported Sunday in a news release.

The crash occurred about 7:45 p.m., near mile post 6, a rural area of Rio Blanco County.

A 2012 Volvo tractor driven by Roy Dunker, 55, of Clifton, was traveling west on the highway when he failed to negotiate a curve to the right and his truck and trailer rolled over on the driver’s side.

The truck and trailer came to a rest off the south side of the roadway in a shallow ditch, the state patrol reported.

Dunker, troopers stated, was hauling a dry box trailer with sodium hydroxide, and during the crash an unknown amount spilled into a shallow area off the south side of the highway.

Dunker was operating the truck for Knight Transportation.

The driver had minor injuries in the rollover and was treated and released from Rangely District Hospital.

Clean-up crews worked through Friday night and into Saturday morning to remove the tractor, trailer and load from the scene.

Highway 64 was closed from the time of the crash until about 2 p.m. Saturday.

Traffic was detoured through the area using Blue Mountain Road (Rio Blanco County Road 1) after road closures were put in place east of Dinosaur and west of the Blue Mountain Road turnoff.

The state patrol is investigating the crash, and excessive speed is believed to be a contributing factor.

Agencies assisting the state patrol were Rangely Fire/EMS, the Craig Hazardous Materials Team, Rio Blanco County Sheriff’s Office, Moffat County Sheriff’s Office, Colorado Department of Transportation and Rio Blanco Road and Bridge Department.

Sodium hydroxide is also known as lye or caustic soda. Basically add it to water to make a strong acid. It is not toxic in terms of being a persistent poison. It is toxic as is bleach where it can be harmful in it's concentrated form.

Hardly worth mentioning as a toxic spill since gallons of water would dilute the minor spill into irrelevance of being less acidic than soda pop.

The Google Monster strikes again. And now I am reminded of a South Park line:

"How do you kill something which has no life?"

Maybe it's the heat down here, but I have scant patience these days with people with airs, and those parroting knowledge as their own.

Thanks, Max. I'll be here all week.

Well, unlike some people I don't mind double checking my facts before I submit a comment. I don't post intentionally false information or ask questions that a simple check can answer.
