Household outage decision timeline
Most outage mistakes happen when households wait too long to protect refrigerator temperature, ration battery watt-hours, or check local alerts. Use these four time checkpoints alongside the interactive planner above.
| Outage checkpoint | Primary household risk | Immediate verification action |
|---|---|---|
| Hour 0–1 | Unnecessary door openings, trip hazards, missed utility alerts | Record outage start time, keep fridge/freezer closed, stage headlamps and NOAA radio |
| Hour 4 (USDA fridge mark) | Refrigerator perishable food rising above 40°F | Transition fridge to backup power or ice-chest cooler; check appliance thermometer |
| Hour 24 (Half-full freezer mark) | Depleted phone/battery banks, indoor temperature drift, freezer thaw | Audit remaining battery Wh, enforce CO-safe 20-ft outdoor generator rule if refueling |
| Hour 48–72 (Extended outage) | Full freezer threshold (48 hr), drinking water depletion, medical power gaps | Verify 1 gal/person/day water reserve and evaluate relocation if indoor heat/cold is unsafe |
Use the planner as an organizing pass, then revisit the plan at the next checkpoint and confirm quantities or equipment limits only in the specialist tool that answers that question.
No. It uses fixed planning choices only. Do not enter names, addresses, health details, equipment models, or load values. The plan stays in this browser unless you choose a local print, export, or My Household Plan save action.
No. This planner organizes supplies for an outage at home. Keep a separate evacuation plan with routes, meeting points, transportation, medications, documents, and local alerts.
No. It identifies questions to verify, not electrical, installation, fuel, medical, or emergency-response answers. Use equipment manuals, qualified professionals, providers, and official local guidance for those decisions.
Plan first. Buy what is missing.
Check what your household already owns before buying new supplies. These documented examples are optional buying research and are not selected from your calculator answers.
