Most fire deaths are not from flames — they are from smoke, at night, in homes where nobody had ever worked out a route. Answer twenty questions about your home and this builds a real escape plan, scores your actual risk, and gives you a short prioritised list of what to fix this week. Everything stays on your device and the plan prints for the fridge.
Working alarms, on every floor, tested. An alarm is the difference between waking in time and not waking at all. Smoke alarms have a service life — usually ten years, printed on the back — and a ten-year-old alarm can be sounding perfectly and detecting nothing. Press the button monthly. Interlinked alarms mean the one that goes off first wakes everyone, not just the floor it is on.
A second way out that has been used. The front door is the first route; it is also the one a fire blocks. People do not rise to the occasion in an emergency, they fall back on what they have actually done. Walk the alternative route out loud with everyone in the house once.
Doors closed at night. A closed door is the single most effective thing between a fire and a sleeping person. It buys minutes, and minutes are the whole currency of a house fire.
Getting out, not fighting it. A waste-bin fire is out in seconds with a blanket or extinguisher. Anything bigger is not, and the smoke gets you long before the flames. If the room is already smoky, get down where the air is better, leave, close the door, call 999 from outside.
