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.
