EnCana is now saying a leak in their pipeline caused by an explosion earlier today did not require the evacuation of residents and workers nearby because only a very small amount of gas escaped before the company shut down the facility and depressurized the pipeline.
Although the leak did not endanger those in the surrounding area, situations like this are perhaps most dangerous for the safety personnel responding to the emergency.
Luc Chretien, Operations Manager for Trojan Safety Services, says sour gas emergencies present a special challenge for first responders who arrive on scene to assess and manage the emergency.

Chretien says that several types of equipment—from air quality monitoring devices to fire control gear—can be required when handling a sour gas emergency.
