03/10/2004, Ingram Trail, NT. Substance: Ammonium Nitrate
During transport on a flatbed trainer, two bulk bags containing ammonium
nitrate fell off the trailer when the straps holding the bulk bags came
loose. The bags ruptured upon impact with the road surface releasing 2,000
kilograms of product. There were no injuries. Company personnel were on
site to clean up the spilled product.
QC. Substance: Vinyl Acetate, Stabilized
During a transfer operation from a rail tank car containing stabilized
vinyl acetate into a tank trailer, an explosion and fire occurred from the
manway cover on the tank trailer burning over 200 litres of product. One
employee who was near the tanker at the time of the explosion suffered
fatal injuries. Emergency response personnel were on site to extinguish
the fire and investigate the cause of the explosion.
ON. Substance: Gasoline and Diesel Fuel
During transport, a tractor tank trailer and B-Train pup containing
gasoline and diesel fuel overturned and was damaged releasing 5,896 litres
of gasoline and 1,000 litres of diesel fuel, some of which entered a storm
sewer and flowed into a nearby river. The driver sustained minor injuries
and was treated in hospital. Emergency response personnel were on site and
evacuated 20 persons from nine nearby homes while they contained and
cleaned up the spill on the road and from the river, before transferring
the remaining products into other tank trailers, flushing the sewer system
and righting the overturned unit.
08/06/2004, Burnaby, BC.
Substance: Hydrogen, Refrigerated Liquid
While setting up to unload from a tank trailer containing hydrogen,
refrigerated liquid, the wrong valve was opened. This sudden release of
hydrogen resulted in the ignition and burning of 1,459 litres of product.
One of the two drivers sustained minor burns and was treated at the scene.
Emergency response personnel were on site and established a one-mile
evacuation perimeter while they cooled the tank with water until they were
able to shut off the valve, which stopped the flow of the product. The
Emergency Response Assistance Plan was activated during the incident.
08/08/2004, Estevan, SK.
Substance: Anhydrous Ammonia
While pushing tank cars into a town spur line at low speed, a train
derailed five rail tank cars containing anhydrous ammonia, four of which
overturned. One tank car sustained a damaged weld, releasing a small
amount of the product. There were no injuries. Emergency response
personnel were on site and evacuated 150 nearby residents while they
checked for leaks and damage, transferred the product from the overturned
tank cars into other tank cars and tank trailers and depressurized and
rerailed all the tank cars. They were then moved under estoppels to a
repair facility. The Emergency Response Assistance Plan was activated
during the accident.
10/06/2004, Radium Hot
Springs, BC. Substance: Liquefied Petroleum Gas
During transport on a downhill curve in rainy weather conditions, a
tractor tank trailer and pup containing 64,000 litres of liquefied
petroleum gas struck a concrete curb. Both tank trailers became
disconnected, broke through the curb and overturned down an embankment
into a pond. The lead trailer ruptured, caught fire and exploded burning
31,5000 litres of product. The second trailer sustained damage and leaked
500 litres of product. The tractor overturned into the opposite ditch and
caught fire, burning completely. The driver sustained fatal injuries.
Emergency response personnel at the site closed the highway while the
fires were extinguished and flared off the remaining 32,000 litres of
product in the second trailer before clearing the accident scene. The
Emergency Response Assistance Plan was activated during the accident.
