A third sour gas leak in two years at a Shell refinery northeast of Edmonton has some residents wondering how safe it is to live in the area known as Upgrader Alley.

A giant fireball erupted above Shell's Scotford upgrader near Fort Saskatchewan on Monday afternoon, sparked by a leak of the highly toxic and flammable gas. About 3,000 workers were sent home, but no one was injured in the incident.

Worker Rod Whitford said it wasn't a big scare.

"Just a routine evacuation that lasted maybe 2.5 hours," he said.

But his wife, Vicky, was more concerned. "This really kind of wakes you up, makes you wonder what's going on," she told CBC News.

The Scotford upgrader, which refines bitumen from Alberta's oilsands into lighter crude oil, is the first facility in Upgrader Alley. There are two more upgraders currently being built and another 10 planned on paper.

Shell officials said Monday's leak of hydrogen and sour gas happened in the hydro conversion unit, the same place where a cloud of sour gas caught fire in September 2006. That forced a plant evacuation and a warning to residents nearby to stay indoors.

One week later, hydrogen sulphide and sulphur dioxide were released from another unit of the plant, prompting another warning.

"I want to move. My husband doesn't want to move, but I want to move, yes. I don't like it being so close," said Vicky Whitford.

"We take these types of incidents very seriously. And given that we had two incidents about 15 months ago and here we are with another one, it certainly isn't what we want to see," said Shell spokesman Randy Provencal.

"We're going to do a full investigation and we're going to find out what the root cause was."

Government agencies continue to monitor air quality levels and have started their own investigations at the Scotford plant, which has begun a $5-billion expansion.

Also on Monday, a Shell pipeline in southwestern Alberta leaked sour gas, prompting the evacuation of 10 homes near Pincher Creek.

Was calling for an investigation into this site two years ago. Guess people will take a hard look at things when the entire region is a fire-ball with toxic clouds heading into Edmonton. Too bad it will be far too late for the many that will die.
