After a Power Surge or Outage: Appliance Safety Steps From Official Sources

After power comes back, wait a few minutes before turning your appliances on, and do not use anything that got wet. If you smell gas, leave right away and call from a safe place.

Key takeaways

  • After power returns, wait a few minutes before turning electronics and appliances back on (SDG&E).
  • During an outage, unplug appliances and electronics, and use surge protectors where you can (SDG&E).

What happened in the area

Storm Rachel brought heavy rain and flooding to parts of Southern California in October 2026, including the Coachella Valley (KESQ, Oct 11) and Long Beach (Fox LA, Oct 13). This page does not say where outages or surges happened. It is a general guide for any home where the power went out, flickered or returned suddenly.

What should I do with my appliances after a power outage or surge?

Follow the steps below. They come from the utilities and agencies named, not from us.

While the power is out

  • Unplug appliances and electronics. SDG&E advises unplugging TVs, appliances and electronics during an outage to reduce overload when power returns, and leaving one light on so you know when it is back.
  • Keep the refrigerator and freezer closed. SDG&E notes that opening them lets cold air escape.
  • Use generators outdoors only. The CDC says never to run a generator or other gasoline engine inside a home, basement, garage, carport or porch, or within 20 feet of a door, window or vent. It also says not to connect a generator to home circuits without an approved device.

When the power comes back

  • Wait a few minutes before turning things on. SDG&E says a sudden spike in demand can cause problems after restoration.
  • Turn appliances on gradually, and reset clocks and timers. This also follows SDG&E guidance.

If water reached your home or appliances

  • Do not use electrical appliances while standing in water. The CDC says never to switch power on or off, or use electrical tools or appliances, while standing in water.
  • Check that everything is completely dry first. The CDC says electrical equipment and appliances should be completely dry before use. If you are unsure whether an item is safe, it advises having a certified electrician check it.
  • Avoid contact with floodwater. The CDC notes that floodwater may contain sewage. It says to discard food that touched floodwater.

If you smell gas

  • Leave immediately and call from a safe place. SoCalGas says to evacuate the area and call from a safe location. The CDC adds: do not use lights or do anything that could create a spark, and do not return until you are told it is safe. If you cannot reach your gas utility, SoCalGas says to call 911.

Food in the refrigerator and freezer

  • FoodSafety.gov (run by USDA and other federal agencies) says food in a refrigerator stays safe for about 4 hours without power if the door stays closed. After 4 hours, perishable foods such as meat, poultry, fish, eggs and leftovers should be discarded.
  • A full freezer keeps food safe for about 48 hours, and a half-full freezer for about 24 hours, if the door stays closed.
  • Perishable food held at 40°F or above for more than 2 hours should be discarded. FoodSafety.gov also says never to taste food to judge its safety: if you are unsure, throw it out.
