The Saint John Fire Department’s hazardous materials team responded Wednesday to a “slow leak” of sulfuric acid from a rail car at a west-side Saint John rail yard. …The rail yard is owned by N.B. Southern Railway, a J.D. Irving company. Arrand said the hazmat team was called and firefighters established a 150-foot perimeter around the rail car while they waited for removal specialists from the Canadian Transport Emergency Centre and RST Transport to arrive. JDI VP of communications Anne McInerney said “All emergency procedures were followed,” and while it’s not confirmed how much acid leaked, the release occurred in a “very small area” and could not have been more than five litres. Arrand said that sulfuric acid presents an inhalation hazard, which was the reason for the perimeter.
