Many deaths from home fires are the result of burns and panic, but most are caused by deadly smoke and gases. These fatal fires are often caused by such careless acts as throwing away a lighted match or cigarette, allowing rubbish to pile up, overloading electrical wires, or misuse of heating and cooking equipment.
Few families go to bed at night without first checking to make sure that the doors and windows are locked, but they overlook a very basic fire safety rule. This rule states that people should sleep with their bedroom doors closed. Nighttime fires are most serious because the family is asleep and the discovery of fire is usually too late.
A closed bedroom door gives extra protection by delaying the gases and fire, thus giving the family a few minutes to escape.
