An escaping cloud of sulphur dioxide gas forced a brief evacuation from Teck Trail Operations Wednesday afternoon.
No injuries were reported when the gas was discharged from the zinc absorption plant after a piece of equipment failed.
As a result, the column of gas blew towards another part of the site away from the plant, kicking the emergency response crews on site into action.
Teck maintained that there was no risk to the community as SO2 monitoring devices registered that there were no elevated levels of the gas.
