The Moldy Potato Hazard: Old rotting potatoes left in a sealed cupboard release concentrated, toxic solanine gas. Inhaling these fumes when opening an old root cellar or deep pantry can cause sudden dizziness and asphyxiation. Don't inhale these fumes. Start storing your potatoes somewhere more open. Do you ever have potatoes rot before you eat them?

No Water for Battery Fires: If a lithium-ion battery (like the one in your phone, laptop, or e-bike) swells or catches fire, do not throw small amounts of water on it. It creates a chemical reaction that releases highly flammable hydrogen gas. Smother it with sand or use a Class D fire extinguisher. Do you have a laptop?

Cold Water Shock: Plunging into water below 60°F triggers an involuntary gasp reflex. If your head is underwater when this happens, you will inhale water directly into your lungs, causing instant asphyxiation. You might want to rethink doing this on purpose (cold water plunge.) Do you ever go swimming?

The Ocean Retreats Before a Tsunami: If you are on a beach and notice the shoreline suddenly recede hundreds of feet out, exposing rocks and fish, do not walk out to look. A massive tsunami wave is minutes away; run for high ground immediately. Do you live by an ocean?
