If you notice any of these in the vicinity of a pipeline, treat as an emergency. In the event of an emergency Remove all personnel from the vicinity of the incident Extinguish any naked flames and shut down all working plant from the immediate area (remember, vapours will travel downwind). Inform the emergency services. If known, call the pipeline operator. There will be a pipeline marker nearby with emergency contact information. Exclude all vehicles and personnel from the vicinity. Do not attempt to seal any leaks. Do not attempt to extinguish the flame if the leak has ignited. If damage to the pipeline does not cause a leak do not try and hide it. Dents and gouges in a pipe may cause it to fail at a later time with, potentially, catastrophic consequences. Report all damage, however seemingly insignificant, to the pipeline operator.
