Fire safety organisations are encouraging people to consider sleeping with their bedroom doors closed at night, saying the habit could help improve safety during a house fire. According to fire experts, a closed bedroom door can slow down the spread of flames, smoke, and toxic gases, giving occupants more time to react and escape safely.
Safety officials explain that modern house fires can spread much faster than in previous decades because many household items, including furniture and decorations, contain synthetic materials that burn quickly. During a fire, smoke inhalation is considered one of the greatest dangers inside a home.
Experts say a closed door may help reduce the amount of smoke entering a room. This barrier can also slow the movement of heat and flames, potentially lowering room temperatures and increasing survival time while emergency services are contacted.
Campaigns such as “Close Before You Doze” have been promoted internationally to raise awareness about the importance of shutting bedroom doors before sleeping. Fire researchers have demonstrated that rooms with closed doors may experience significantly less smoke damage and lower temperatures during a fire compared to rooms with open doors.
Apart from fire protection, some people also choose to close their bedroom doors to reduce outside noise and improve sleep quality. A closed door may help block sounds from traffic, neighbours, televisions, or activity inside the home.
Security experts also note that locked or closed doors may create an additional barrier during emergencies such as break-ins, potentially giving occupants more time to call for help or escape safely.
However, fire safety officials stress that keeping bedroom doors closed should not replace other important safety measures. Homes are still encouraged to install working smoke alarms, create emergency escape plans, and regularly check electrical appliances and wiring to reduce fire risks.
Families are also advised to ensure that windows and exits remain accessible in case evacuation becomes necessary during an emergency.
According to Erie Insurance – Close Before You Doze and Fire Services South Africa, closing bedroom doors at night may help slow the spread of smoke and fire during household emergencies.
