Drill / 03

The one-hour power-outage test.

A short rehearsal can show whether your household has light, water, food, medication and communication covered after the convenience systems stop.

Keep the drill small and reversible. Its job is to reveal a missing step.

Power outages create secondary problems: a refrigerator is opened repeatedly, a phone becomes the only light, a generator is moved too close to a door, or a refrigerated medicine plan is unclear. CDC guidance emphasizes that outages can create carbon-monoxide, food, water and medication hazards. A planned one-hour test helps you find the household-specific problem before you are tired, cold or trying to help someone else.

Safety boundary: do not turn off a medical device, heating or cooling system, alarm, refrigerator containing essential medication, or other life-safety equipment. Do not run a generator, grill or gasoline engine indoors, in a garage, or near doors and windows. Follow local utility and health-department instructions during a real outage.

Set up before the timer starts

Gather a working flashlight or lantern, a charged phone and power bank, a manual can opener, drinking water, a paper contact card and the refrigerator and freezer thermometers you already use. Tell everyone that this is a rehearsal and choose a comfortable hour when no one depends on powered equipment you plan to interrupt.

The 60-minute sequence

  1. Minute 0–10: communication. Put phones on low-power mode. Ask each person where the paper contact card is and how they would receive an official alert if Wi-Fi failed.
  2. Minute 10–20: light and movement. Use only your backup light for a few minutes. Walk the route to the bathroom, exit and electrical panel. Add a light where a trip hazard appears.
  3. Minute 20–35: food and water. Keep refrigerator and freezer doors closed. Identify the thermometer, cooler and cold source you would use if the outage continued. CDC says a closed refrigerator keeps food safe for up to four hours; a full freezer can hold temperature for about 48 hours, and a half-full freezer about 24 hours.
  4. Minute 35–45: personal needs. Read the labels for medicines or devices that need power or refrigeration. Write down who you would call for guidance; do not guess about a medication’s stability.
  5. Minute 45–55: home safety. Check that every adult knows never to use a generator, charcoal grill or camp stove inside. Look at the location where a generator would operate outdoors and confirm its exhaust cannot enter a home or neighboring space.
  6. Minute 55–60: reset. Return equipment, recharge what you used and write one fix. Keep the list short enough to complete.

Turn observations into improvements

The power bank cable did not fit the phone.Store a tested cable with the bank and label the device.Repeat a five-minute charge next month.
No one knew the out-of-area contact.Print the contact card and place one copy in each go-bag.Ask a child or guest to find it.

Keep the rehearsal on a seasonal calendar. CDC’s food-safety guidance, utility outage patterns and your household’s prescriptions may change. A short test repeated twice a year is easier to maintain than a dramatic drill that no one wants to repeat.
