SAINT JOHN, New Brunswick (AP) — An explosion at Canada's largest oil refinery has sent one man to hospital with minor injuries, officials said Wednesday.
Fire platoon Chief Brian Wilson said a tank exploded at the Irving oil refinery in Saint John, New Brunswick.
Wilson said the explosion involved a 1,100-barrel tank of potassium hydroxide, which is a caustic substance.
He said the injured man was blown to the ground and suffered some scrapes and bruises. He said crews from Irving are cleaning up the scene.
Irving Oil issued a statement saying the tank was undergoing scheduled maintenance work at the time when it became over-pressurized. The company said there was no other damage. Normal operations at the refinery resumed less than an hour later.
The refinery produces more than 300,000 barrels of petroleum products per day.
