Smoke — the silent killer: surviving the first minutes

90% of fire victims die from smoke, not flames: CO kills in 3–4 breaths, hot air burns lungs, plastics release cyanides. Smoke rises — clean air is at the floor. Rules: crawl low (on all fours!), cover mouth with wet cloth, NO lift, close doors behind you (30+ min smoke barrier), breathe through wet clothing. A €10 smoke alarm saves nights — mandatory in bedroom and hallway.

💨 Smoke rises ~4 m/s — faster than a runner. 60 seconds after ignition the stairway may be impassable: know your escape route by heart.
