Appliance Earthquake Safety in California

This preventive guide helps you proactively protect your home from appliance-related hazards. Completing these steps significantly reduces your risk of an appliance emergency.

Steps to Take Now#

These actions should be taken as soon as possible to address the identified hazard:

1. After any earthquake, check for the smell of gas — if detected, follow the gas leak emergency protocol (evacuate, call PG&E at 1-800-743-5000)
2. Check all gas appliance connections visually — look for disconnected flex connectors behind the range, dryer, or water heater
3. Inspect the water heater for shifted position or leaking — an unstrapped water heater can topple and sever the gas line
4. If a refrigerator has shifted, check the water supply line behind it — a kinked or broken copper line causes flooding
5. Do not turn gas appliances back on after a felt earthquake until you have visually inspected every connection

Why This Matters#

Appliance safety is often overlooked until an incident occurs. Taking proactive steps to address known hazards protects your family and your property. The steps in this guide are based on CPSC safety data, manufacturer recommendations, and California building code requirements specific to the [Sacramento](/sacramento/sacramento) area.

What Long-Term Prevention and Maintenance Is Needed?#

After addressing the immediate situation, implement these long-term measures to prevent recurrence:

• Install a seismic gas shutoff valve on the main gas line — California law (HCD 2019 code) recommends them and some municipalities require them for sale
• Strap your water heater with seismic bracing per California Health & Safety Code Section 19211 — required for all water heaters since 1996 and at point-of-sale since 1995
• Use flexible gas connectors (CSA-approved stainless steel) on all gas appliances — rigid connections crack during seismic movement
• Secure the refrigerator to the wall with a furniture strap — a full refrigerator weighs 250-400 lbs and can topple during moderate shaking
• If your home sits on a raised foundation (common in older Sacramento neighborhoods like [Land Park](/sacramento/sacramento/land-park), [Oak Park](/sacramento/sacramento/oak-park), [Curtis Park](/sacramento/sacramento/curtis-park)), consider foundation bolting — this prevents the entire structure from shifting off the foundation
• Store heavy items on lower shelves inside refrigerators and freezers — top-heavy units tip more easily
• Keep a wrench near the gas meter for manual shutoff — the meter shutoff valve requires a 12-inch adjustable wrench turned 90 degrees

Official Resources and Contacts#

These official resources provide authoritative information and assistance:

• California Seismic Safety Commission — State guidance on earthquake preparedness including appliance and water heater strapping requirements.
• PG&E Earthquake Safety — PG&E resources for securing gas lines and what to do with gas appliances after an earthquake.
• City of Sacramento Building Division — Local building code information including seismic appliance requirements for Sacramento homes.
• CEA Earthquake Insurance — California Earthquake Authority — earthquake insurance covering appliance damage and gas line repairs.

Frequently Asked Questions#

Do I need a seismic gas shutoff valve in California?#

California does not universally mandate seismic shutoff valves for existing homes, but many local jurisdictions — including parts of the Sacramento metro area — require them at point-of-sale or during remodels. The valve automatically shuts off gas when it detects seismic activity above a set threshold (typically 5.1 on the Richter scale). Installation varies by model and condition including the valve and licensed plumber. After the valve trips, a gas utility technician or licensed plumber must manually reset it — so you may be without gas for hours after a moderate earthquake even if nothing is damaged.

Is water heater strapping required in California?#

Yes. California Health & Safety Code Section 19211 requires all water heaters to be braced, strapped, or anchored. This has been the law since 1996 for new installations and since 1995 at point-of-sale. The strapping must use steel straps (not plumber's tape), one in the upper third and one in the lower third of the tank. Kits varies by model and condition at hardware stores. Professional installation runs. Non-compliance can affect home insurance claims and create liability in a sale.

What appliances are most dangerous during an earthquake?#

In order of risk: (1) Gas water heater — can topple and sever the gas line, causing both fire and flooding. (2) Gas range — can disconnect from the gas supply if it shifts, causing a gas leak. (3) Refrigerator — heavy enough to cause injury if it topples, and the water supply line can flood the kitchen. (4) Washer/dryer — heavy and top-heavy when loaded, likely to shift and potentially disconnect gas (gas dryer) or water (washer). Securing all four appliances takes about 2 hours and costs under in materials.
