When the power goes out, most people reach for the same things: flashlights, candles, maybe a battery-powered radio. But the item that ends up mattering most in a real blackout emergency is one almost nobody thinks about — and it’s probably sitting in your fridge or pantry right now.
Baking soda.
Why it matters
Blackouts don’t just take away your lights. They quietly change how you cook, how you see, and how you move around your own home — and that combination is exactly what causes a spike in house fires during extended outages.
Here’s the pattern fire departments see over and over: the power goes out, someone lights a few candles for light, and then someone else tries to cook on a stovetop, a camp burner, or even an open flame because the usual appliances are down. Add in poor visibility and unfamiliar setups, and small grease or candle fires become far more common — and far more dangerous — than people expect.
Why baking soda, specifically
Water is the instinct most people have when something catches fire. In a blackout, that instinct can make things worse.
- On a grease fire, water causes the burning oil to splatter and spread, sometimes explosively.
- On a candle wax fire, water can do the same thing, since wax behaves like a light oil once it’s burning.
- On a small electrical fire, water conducts electricity and puts you at risk of shock.
Baking soda works differently. When it hits flame, it releases carbon dioxide, which smothers the fire by cutting off its oxygen supply — and it does this without spreading burning liquid across your kitchen or countertop. It’s essentially a mild version of what’s inside a real dry-chemical fire extinguisher.
How to actually use it
- Keep an open box within reach of wherever you’re likely to be cooking or using candles during an outage — not tucked in the back of a cabinet.
- For a small stovetop or grease fire: turn off the heat source if it’s safe to reach, then scoop or pour baking soda directly onto the base of the flame until it’s smothered.
- For a candle-related fire: smother the flame the same way rather than trying to blow it out or move it.
- Know the limit: baking soda works on small, contained fires — roughly frying-pan size or smaller. If a fire is spreading, already large, or you’re unsure, get everyone out and call for help immediately. It’s not a substitute for a real fire extinguisher, and it won’t help with a fire that’s already climbing a wall or cabinet.
The bigger picture
Baking soda isn’t a replacement for basic blackout prep — flashlights, a charged power bank, and a plan for food safety still matter. But it’s the one item that directly addresses the new risk a blackout creates: open flames in a home that isn’t set up for them, handled by people who aren’t used to putting fires out by hand.
It’s cheap, it’s already in your kitchen, and unlike most “survival” advice, it doesn’t require you to buy anything or change how you live. You just have to know it’s there — and know what it’s for — before the moment you actually need it.
