If you suspect there is a damaged natural gas pipeline, contact the emergency line. Call even if you think the damage is minor; a small scrape or a stretched pipe can cause problems with the line in the future.
If the damage results in a release of gas, evacuate the area immediately and extinguish all ignition sources. Don’t try to fix the line by crimping, bending or otherwise restricting gas flow. That could cause a dangerous buildup of static electricity that could spark ignition.
Contact the emergency line to report the damage. If life or property are in danger, call 911 or your local fire department. Wait for an ENSTAR employee to arrive and address the situation.
