Electrical Safety Tips for California Earthquakes

In the aftermath of a major earthquake, the single greatest threat to residential neighborhoods isn't structural collapse—it is fire. Broken gas lines and spark-producing short circuits in walls create a highly hazardous combination. Preparing your home's electrical infrastructure beforehand can save lives and properties.

Here are the essential electrical safety steps to take before, during, and after an earthquake:

1. Know the Location of Your Main Electrical Breaker

In an emergency, you must be able to shut off all electricity to your home instantly. Locate your main panel box (usually on the exterior wall of the garage, basement, or utility room). Find the **main circuit breaker switch** (usually a double-width switch at the top rated at 100 to 200 Amps). Make sure the panel door is unlocked and easily accessible at all times.

2. Secure Large Electrical Appliances

Heavy appliances like refrigerators, water heaters, and washing machines can easily tip over during seismic activity, pulling wires loose and causing severe arcs. Use heavy-duty metal strapping to secure these appliances directly to wall studs. California code strictly requires water heaters to be double-strapped for this reason.

3. Install AFCI Breakers

Arc-Fault Circuit Interrupters (AFCIs) are advanced breakers that detect tiny changes in electrical current that indicate sparking (arcing) behind walls. If an earthquake stresses or pinches a wire inside your walls, an AFCI breaker will detect the arc and shut off power instantly, preventing the wire from starting a drywall fire.

4. Post-Quake Inspection: What to Do After the Shaking Stops

Once it is safe to move, inspect your home's utility lines carefully:

• If You Smell Gas: Do NOT turn any light switches on or off, and do NOT plug or unplug anything. The tiny spark inside a light switch can ignite leaking gas. Evacuate the house and shut off the main gas valve immediately.
• Turn Off Electricity If You Suspect Damage: If you see sparking outlets, fallen light fixtures, or smell electrical burning, shut off the main breaker to make the home safe.
• Watch Out for Downed Lines: Always assume downed outdoor power lines are live. Stay at least 30 feet away and report them immediately to emergency services.
