A bedroom fire can turn a sleeping household’s world into a race for survival.

But as toxic smoke spreads, one ordinary bedtime habit may help protect the space where your family sleeps. It offers no guarantee, yet behind that closed door could be precious time to respond before a familiar home becomes a place of sudden and unimaginable dang…

Closing your bedroom door before sleep can slow the entry of heat and toxic smoke during a house fire. Modern synthetic furnishings can burn rapidly, releasing carbon monoxide and other dangerous gases that may overwhelm people before they escape.

A closed door is not fireproof and cannot ensure breathable air, but it can help maintain more survivable conditions while you respond. That is the practical purpose of “Close Before You Doze”: a simple habit, not a promise of safety.

Pair it with interconnected smoke alarms inside bedrooms, outside sleeping areas, and on every level. Test them regularly and practice two escape routes whenever possible. When an alarm sounds, leave immediately by a safe route; never investigate or gather belongings.

If heat or smoke blocks escape, keep the door closed, call emergency services, and signal from a window. Once outside, stay outside. Tonight’s preparation could help protect everyone you hope to wake beside tomorrow.
