Pipeline Incidents Safety Brief
Signs of a Potential Pipeline Leak
What you may smell

Being A Partner in Pipeline Safety
Although a pipeline leak is rare, it is important to know how to recognize the signs. Use your senses of smelling, seeing and hearing to detect a potential pipeline leak.
Responding to a pipeline incident
A pipeline incident could involve an uncontrolled or unplanned release of oil from the pipeline system. TransCanada’s state-of-the-art leak-detection systems, elevated safety features and specially trained staff make us confident leaks would be quickly identified and responded to.
In the unlikely event of an incident, TransCanada’s top priorities are to ensure the safety of the public and minimize effects on the environment and surrounding properties.
Pipeline incident response includes:
- TransCanada will immediately respond by shutting down the pipeline and dispatching emergency personnel to the location of the incident
- Valves spaced at intervals along all TransCanada pipelines will be shut off allowing incidents to be quickly and effectively isolated
- Trained crews are dispatched to the site to further isolate the area and coordinate a response with local emergency services
- TransCanada will not restart the pipeline until the issue has been identified, resolved and it is safe to do so
- TransCanada’s policies and practices for emergency response planning go above and beyond the standard regulatory requirements for emergency response
- TransCanada does not expect volunteer or dedicated local fire departments to have the equipment or specific experience needed to respond to a leak or rupture
- We work with emergency response officials in a Unified Command to ensure everyone are familiar with local operations and is ready to respond in the event of an incident
- Our crews will respond immediately
