Emergency Refrigeration: Why Cold Storage Belongs in Your 72-Hour Preparedness Plan
Power outages can turn food storage into a time-sensitive problem. Build a practical 72-hour plan around safe temperatures, shelf-stable food, measured cold storage and realistic backup options.
Emergency planning should include more than flashlights and phone chargers. The Government of Canada recommends being prepared to care for yourself and your household for at least 72 hours. Food and water belong at the centre of that plan, including a strategy for anything that depends on refrigeration.
Build your emergency food supply in two layers. Keep enough non-perishable food to get through an interruption without depending entirely on a refrigerator or freezer, then identify the perishable foods that would need protected cold storage if power is lost. This reduces the amount of food competing for limited cooling capacity.
Measure temperature instead of guessing. Health Canada advises setting a refrigerator at or below 4°C (40°F) and a freezer at or below -18°C (0°F). A refrigerator or cooler thermometer gives you useful information when deciding whether food has remained adequately cold.
During a power outage, keep refrigerator and freezer doors closed unless necessary. Current federal guidance says an unopened refrigerator will generally keep food cold for about four hours, a full freezer for about 48 hours and a half-full freezer for about 24 hours. Those are planning estimates, not substitutes for checking actual food and storage conditions.
Prepare before the outage. Organize shelf-stable meals, keep thermometers available, know where insulated coolers are stored and consider how you would protect temperature-sensitive food during a longer interruption. Do not use winter outdoor temperatures as a substitute freezer: federal guidance warns that animals can contaminate food and sunlight can thaw it even when outdoor air is very cold.
Cold storage is one part of a broader 72-hour system that should also include safe water, communication, lighting, first aid, medications and household-specific needs. The goal is resilience: fewer single points of failure when normal infrastructure is unavailable.
FLAMECOOL is being developed around that same independence-first philosophy: portable active cooling for compatible standard-size coolers when conventional electrical infrastructure is unavailable or inconvenient. We will continue sharing useful public-facing refrigeration and preparedness information while FLAMECOOL's proprietary engineering, internal component relationships, refrigerant-circuit details and trade-secret operating principles remain confidential.
