Oklahoma derailment and explosion (August 2008)

LUTHER, Okla. - A train carrying crude oil derailed around 2:30 p.m. on Friday, August 22, 2008 in rural northeastern Oklahoma County. Approximately 8 cars of the 110-car train had crude oil and ethanol.  Firefighters let the blaze burn itself out, but the fire didn't die out until shortly after sunrise Saturday morning.

A BLEVE event only needs 1 car or storage tank or container holding petroleum product. It is the high energy explosion that takes place when direct heating of the tank car or storage tank, etc. causes the tank car to physically fail and suddenly split/explode sending the steel off like a rocket, hundreds of pounds of steel upwards of 3/4 of a mile away.

These kinds of explosions have been described as, “…akin to a World War Two Firebombing or a Nuclear explosion, the temperature in the blast area reaching up to 3,000 degrees Celsius.”

BLEVE kind of means a domino effect? The explosion of one car touches off the next one?

One acronym, BLEVE. The important issue is that there were only a maximum 8 cars of petroleum products involved, but no one knew that at the time because rail carriers don’t have to tell anyone what they are transporting which means responders have to sit and wait until they know.

In this case, the crude oil liquid in the tank car absorbed heat and volatilized, leaving more of the tank car’s steel wall exposed to direct heat which further increased the inner tank pressure, finally resulting in tank failure and a Boiling Liquid Expanding Vapor Explosion. This is the exact phenomena that would level buildings, elevated highways and all infrastructure in a confined downtown environment. The pilot remarks how lucky this happened 2 miles out of Luther and not downtown.

2008 is early but it still could have been fracked oil from the Bakken. This is probably when all the oil was still going through Cushing, OK.
