Extended power loss causing comms failure. Priorities: avoid hazards, conserve power, maintain contact cadence. Actions: keep fridge closed; avoid candles (use flashlights); ventilate generators outdoors; check CO alarms; avoid elevators; secure stairwells. Comms: SMS on schedule; designate one “family phone”; charge at shelters/vehicles (engine off, windows open). Info: battery radio for local broadcasts. Payments: carry cash—ATMs/POS may be offline. Japan: 110/119, 171, municipal shelters, community FM/NHK. Start with SAFE-BRIEF; add plan/checklist per intent; end with emergency-number reminder.
