Frequently Asked Questions
What is a gas distribution incident?
Gas distribution incidents involve failures in the local natural gas pipeline network — leaks, ruptures, explosions, and equipment failures that can cause property damage, injuries, and fatalities. PHMSA requires all operators to report significant incidents.
How can I protect my home?
Install CO detectors on every level (CPSC recommendation). Have gas appliances inspected annually. Know the signs of a gas leak: rotten egg smell, hissing near gas lines, dead vegetation near pipelines. If you suspect a leak, leave immediately and call 911.
