Or natural gas. Depends on your location.
If the situation is so dire natural gas supply fails, it's time to leave unless you have a tertiary system in place.
Think about it. If a natural disaster can disrupt the propane or natural gas delivery system, will your house be standing?
This was a relatively mild winter storm in western WA. Maybe we had snowfall and temperatures below +30 degrees Fahrenheit. In other words - it didn't take much. Just enough demand to overwhelm the system. My house wasn't affected.
That time, my NG supply wasn't lost either, and I'd have never known that it was close, if not for a well connected friend who had been sitting inside the room while decisions were being made. I do regularly lose power (in another part of the country) despite having underground lines. Why? For the same reason I almost lost gas - I'm at the end of the line (for power).
Sometimes it gets cut by the company, and during a major event, it is often the last to come back on. Three houses down is on a different circuit - they are typically back up much more quickly.
