BLEVE
“We’re in the big hole, Ted, but still moving.”
“Jesus Christ, Ted, one of them tank cars blew up…”
In the middle of the next city west of Toronto, there are twenty-four cars piled in a heap. Nineteen contain “Dangerous Commodities”. Within half-an-hour three of the propane tankers have exploded; parts of these cars have gone 145 feet east, 440 feet southeast and 2,222 feet northeast. The front of the train has stopped just over a mile away.
Good luck is with us tonight; the train has passed through the town of Streetsville and the derailment is in the middle of an industrial area.
The heat of the fire on the tank cars caused BLEVE’s – Boiling Liquid Expanding Vapour Explosion. The liquid in the tank cars has been heated to the point it is vaporized and the tank can no longer contain the pressure. Applying Boyle’s law, when the tank ruptures the pressure decreases abruptly and any remaining hot liquid vaporizes instantly, and may shoot the tank a considerable distance.
And in the middle of all this is a tank car of Chlorine. And this tank has a 2 to 3 foot diameter hole in it. The year before, a Youngstown, Florida, a chlorine tanker was punctured in a derailment and 50 tons of chlorine drifted over a highway and killed 8 motorists and their passengers and hospitalized 89.
By Sunday, a large part of Mississauga had been evacuated, as well as bits of two neighbouring municipalities – Burnhamthorpe Road to the lake, from Highway 10 to Erin Mills Parkway/Southdown Road – 17.4 square miles and 75,000 people. The evacuation lasted until Friday.
