A backdraft is a deadly explosion that happens when a fire has been burning in a closed space with very little oxygen left. The trapped gases inside are extremely hot and full of unburned fuel vapors. As the fire burns, heat causes nearby materials to decompose in a process called pyrolysis. This releases flammable gases like hydrocarbons even when there isn’t enough oxygen for full combustion. These gases can stay inside at temperatures hundreds of degrees Celsius above normal air. When someone

Hautelluxurylife on Instagram: "🔥 Backdraft Explained: When Fresh Air Meets Fire! 😱💨 Watch this video to see how firefighters demonstrate the dangerous phenomenon known as a "Backdraft" using a controlled setup. Why does this happen? (The Science) 🧠 When a fire burns in a closed room, it slowly consumes all the available oxygen. The fire technically "dies down," but the room remains filled with superheated gases and smoke (which acts as fuel). As soon as a door is opened and fresh oxygen
