Power Outage Safety: What to Do During a Power Outage and How to Use a Generator Safely

Contents

If you lose power, never run a generator inside your home, garage or carport, and never plug it into a wall outlet. Run it outdoors, at least 20 feet from doors, windows and vents, and use a carbon monoxide alarm. For anything wired into your home, use a professionally installed, approved connection.

Is there a power outage in my area?

Tropical Storm Rachel, later described as a post-tropical system, brought heavy rain, coastal flooding and high surf to parts of Southern California between about October 9 and 12, 2026, and its remnant moisture reached Las Vegas. San Diego County’s alert page listed Tropical Cyclone Rachel on October 9, and the City of Newport Beach declared a local emergency for it. Impacts were not the same everywhere. A KPBS report dated October 12 described 17 downed power lines and five transformer fires in San Diego over the weekend of October 10 and 11. Reports for Newport Beach, Long Beach, Riverside County and Las Vegas did not give outage numbers. Check your own address on SCE, SDG&E or NV Energy.

What to do during a power outage

  1. Check whether only your home is affected. A tripped breaker can be the cause.
  2. If neighbors are dark too, report it: SCE 1-800-611-1911, SDG&E 1-800-411-7343.
  3. Do not go outside to check lines or equipment while it is flooding or if wires may be down.
  4. Use battery flashlights, not candles.
  5. Unplug sensitive electronics so a surge on restoration does not damage them.
  6. Keep the refrigerator and freezer closed.

“Use generators and any gas-powered equipment outside, at least 20 feet away from doors, windows, and vents”

How to use a generator during a power outage safely

CDC and ESFI give clear rules. Generators produce carbon monoxide, which you cannot see, smell or hear.

  • Run it outdoors only. Never in a house, basement, garage, carport or on a porch.
  • Keep it at least 20 feet from any door, window or vent, even if they are open.
  • Use heavy-duty, outdoor-rated extension cords and GFCI protection.
  • Let it cool before refueling, and store fuel safely away from the unit.
  • Install battery-operated carbon monoxide alarms and test them before the outage.

If anyone has a headache, dizziness, weakness or nausea while a generator is running, get to fresh air and call 911.

Can I connect a generator to my household wiring?

Only through an approved, professionally installed connection. CDC’s flooded-home guidance warns against connecting a generator to your home’s electrical circuits, and ESFI says generators should be installed by qualified electricians. ESFI recommends a qualified electrician install a listed transfer switch. Power that flows backward into the grid is called backfeeding, and it can seriously injure line crews. Never plug a generator into a wall outlet or use a homemade cord with plugs on both ends.

What if the storm damaged my circuits?

  • Warning signs: breakers that trip repeatedly, warm or discolored outlets, flickering lights, buzzing or a burning smell.
  • Do not keep resetting a breaker that trips.
  • Do not use outlets, switches or cords that were wet.
  • Leave affected circuits off and have a qualified electrician assess them.
  • If you see smoke, sparks or fire, leave and call 911.
