GATINEAU, QC, Nov. 17, 2011 /CNW/ - The Transportation Safety Board of
Canada (TSB) today released its final investigation report (R10T0020)
into the 09 February 2010 catastrophic failure and derailment of a
dangerous goods tank car at the MacMillan Yard in Toronto, ON. The
report and photo gallery are available on the TSB website at www.bst-tsb.gc.ca .
On 09 February 2010, a non-pressure dangerous goods tank car broke into
two sections and derailed during switching operations at Toronto's
MacMillan Yard. When the car failed, it released its entire load of
57 000 litres of ferric sulphate along the roadway and adjacent tracks.
A total of 2 cars had derailed and 3 additional cars were damaged.
There were no injuries.
The investigation report identifies safety deficiencies regarding the
attachment of equipment to tank car shells, the properties of materials
used to construct non-pressure tank cars prior to 1990 and the
inspection standards and methods used to inspect tank cars during
requalification. Throughout North America, there are approximately
82 000 railway non-pressure tank cars built prior to September 1990,
which were built with similar material and design features to the tank
car that failed.
The industry and regulators in Canada and the United States of America
have developed a number of strategies to deal with the issues
identified in the report.
The TSB is an independent agency that investigates marine, pipeline,
railway and aviation transportation occurrences. Its sole aim is the
advancement of transportation safety. It is not the function of the
Board to assign fault or determine civil or criminal liability.
