Is It Safer To Go To Bed With The Door Closed Or Open?
By JOANNA MARIE
In the dire circumstances of a house fire, your closed bedroom door serves a great purpose. It stands as a protective barrier against the fire and keeps you safe.
Fires need three elements — fuel, heat, and oxygen, known as the fire triangle — and cannot begin or spread if any one of these components is missing.
Since a fire burns more quickly and fiercely with more oxygen, closing your door reduces the oxygen it has access to and restricts the spread of the fire.
A closed door may considerably delay the spread of flames, reduce harmful smoke, increase oxygen levels, and lower temperatures in the event of a fire.
The Federal Emergency Management Agency (FEMA) notes that 49% of most home fires occur between 11 p.m. and 7 a.m., which further justifies why doors should be closed at night.
Smoke, also known as “the silent killer,” is far deadlier than fire. It spreads faster and farther than heat and flames and carries toxic gasses that disorient and harm you.
Closing your door essentially blocks a significant portion of dangerous smoke from reaching you, thereby increasing your safety.
