How Do We Stay Safe During a Multi-Day Power Outage?
The four outage problems in order: food safety (4-hour fridge / 48-hour freezer rules per FDA), heat when the AC is out in a Gulf Coast summer, medical equipment that needs power, and the restoration surge that damages electronics when the lights return.
A multi-day outage is four problems in order: keeping food safe, keeping people cool (or warm), keeping medical equipment running, and protecting your electronics for the moment power returns. On CenterPoint and TNMP territory, storm outages of hours are routine and direct-hit outages can run days to weeks — so the plan below assumes days. None of it requires special gear beyond what the prep checklist already staged.
How long does food actually stay safe without power?
The FDA's numbers, worth writing on the fridge door: a closed refrigerator keeps food safe about 4 hours; a full freezer holds about 48 hours (24 if half-full). The discipline is door management — every open costs cold. Group refrigerated items together, move the must-keeps to the freezer early, and use the coolers-and-ice plan for the things you'll actually reach for. After that window, the rule is “when in doubt, throw it out”: perishables above 40°F for more than 2 hours go, and taste-testing is not a food-safety method. A generator changes this entirely — a refrigerator draws little, and even a small portable resets the clock — which is what the generator storm guide is for.
What does heat safety look like when the AC is out in August?
A Gulf Coast summer outage is a heat emergency, not an inconvenience — this region's heat index tops 100° for weeks at a stretch, and indoor temperatures in a closed house climb fast. The playbook: chase the coolest room (lowest floor, shaded side), move air with battery fans, wet washcloths and cool showers beat sitting still, hydrate on a schedule rather than thirst, and check hourly on infants, elders, and anyone on heat-sensitive medications. Know the escalation signs — confusion, hot dry skin, and no sweating mean heat stroke, which is a 911 call. And set an honest trigger for leaving: a cooling center, a relative's powered house, a hotel inland. Toughing out an August week without cooling is how heat deaths happen after storms; the households that do fine either left or had backup power sized to run the AC.
What's the plan for medical equipment that needs power?
Decide it before the season, not during the outage. If anyone in the home depends on powered equipment — oxygen concentrators, CPAP, home dialysis, powered mobility, refrigerated medication — register with your utility's critical-care program (CenterPoint and TNMP both run one; it flags your account, though it does not guarantee restoration priority) and file a plan with two layers: a battery/generator bridge for short outages, and a non-negotiable relocation trigger for long ones. Refrigerated medications ride the same FDA clock as food — a small cooler with ice packs dedicated to meds is cheap insurance. This is also the single strongest case for a standby generator with an automatic transfer switch: it removes the 3 AM scramble entirely.
Why do electronics die when the power comes back — and what do I unplug?
Restoration is the roughest electricity your house sees. As crews re-energize sections of the grid, voltage can sag, spike, and cycle — and everything in your house that was “on” when the lights went out slams back simultaneously into that instability. The defense is simple: when the outage starts, unplug the valuable electronics (TVs, computers, game consoles) and switch the AC off at the thermostat, leaving one lamp on as your restoration signal. When power returns, give it a few minutes to hold steady, then bring loads back in stages, AC last. A whole-home surge protector automates most of this protection at the panel — and if the AC won't start or a breaker trips repeatedly after restoration, stop resetting and read the post-storm electrical guide.
Quick answers
How long is food safe in the refrigerator during an outage?
About 4 hours if the door stays closed, per the FDA. A full freezer holds about 48 hours (24 if half-full). After that, perishables above 40°F for more than 2 hours should be discarded — when in doubt, throw it out.
Should I unplug things during a power outage?
Yes — unplug sensitive electronics and switch the AC off at the thermostat as soon as the outage starts. Restoration voltage is unstable, and the surge when power returns damages more equipment than the outage itself.
Who do I call about medical equipment during outages?
Register in advance with your utility's critical-care program (CenterPoint Energy or Texas-New Mexico Power for this area). It flags your account — but it doesn't guarantee power, so you still need a battery bridge and a relocation plan.
Five minutes with a real person sorts out whether your outage plan needs a transfer switch, a standby generator, or just surge protection — honest answers, no pressure.
