Earthquakes don’t give us a heads-up; they strike fast and without warning. That’s why preparation is key, especially regarding natural gas safety.
Whether you’re managing a fleet facility or a small business, a few proactive steps can go a long way in keeping your team safe when the ground starts to shake. SoCalGas shares some advice that will help.
BE PREPARED BEFORE THE QUAKE HITS
- Know Your Gas Meter Location: Find out exactly where your gas meter is located. Store a 12-inch (or larger) adjustable wrench nearby, preferably close to the building exit or right next to the gas shut-off valve. Just don’t attach the wrench directly to the meter.
- Make a Safety Checklist: Include gas shut-off tools in your emergency kit. Check that smoke and carbon monoxide detectors are in working order and stocked with fresh batteries.
- Walk Through a Safety Drill: Make sure everyone in your household or facility knows how to drop, cover, and hold on. Practice safety steps now so they come naturally in an emergency.
AFTER THE SHAKING STOPS
- Don’t Rush to Turn Off the Gas: Only shut off your natural gas if you smell gas, hear it hissing, or see clear signs of a leak — and only if it’s safe to do so. Shutting off the gas unnecessarily can lead to longer wait times to restore service.
- If You Turn it Off, Leave it Off: Never turn your gas back on yourself. Interior lines and appliances need to be inspected first. SoCalGas or your utility provider must handle the gas restoration to the meter.
- Avoid Anything That Sparks: Until you’re absolutely sure there’s no leak, don’t light matches, flip switches, or use any electronics that could cause a spark.
- Call the Right Help: If there’s an issue, contact your gas utility. They’ll relight pilot lights and inspect appliances, but keep in mind, some repairs might need to be handled by your plumber or heating technician.
When disaster strikes, the first step to staying safe is being ready for it.
