Install an Automatic Gas Shut-off Valve

04/25/2023

Why does it matter?

Deadly and destructive fires frequently follow earthquakes. In 1906, the infamous 7.8 magnitude San Francisco earthquake and ensuing fire killed 3,000 and razed large city sections, making it the most deadly in U.S. history. In modern times, severed gas lines are often the source of ignition, so it is essential to plan for and mitigate against the threat of fire.

One of the most effective ways to reduce fire risk after an earthquake is to locate your gas supply and understand how to interrupt the flow.

What do I need to know?

• Install an automatic gas shutoff valve that activates when sensors register ground shaking or an increased gas flow. 
• If you do not have an automatic system, purchase a wrench and locate the valve to ensure you can manually turn off the gas supply to prevent a fire or explosion after an earthquake.
• Store the wrench near your gas supply valve, and ensure you and your family know how to use it. 

Where do I start?

• Contact your gas utility provider for more information about how to have a shutoff valve installed.
• Learn how to turn off the gas supply after an earthquake, as well as how to have your gas turned back on once the danger has passed.
