Research findings:

· When a fire breaks out in a home, the average temperature in a closed bedroom is less than 100 degrees Fahrenheit (approximately 37.7°C);

· The average temperature in an open room may exceed 1,000 degrees Fahrenheit (approximately 537°C), enough to melt the house. Electrical appliances and furnishings inside. Even after the fire was extinguished, the temperature in the room with the door open was nearly 500 degrees Fahrenheit (260 degrees Celsius).

In addition to high temperatures, the most terrifying aspects of fires are thick smoke and carbon monoxide poisoning. In the picture above, it is already clear how important a bedroom door is in blocking smoke. What about carbon monoxide?

Experiments by the U.S. Fire Safety Research Institute (ULFSRI) concluded:

· The carbon monoxide content in a bedroom with the door open soared to 10,000 ppm;

· While the door was closed The carbon monoxide level in the bedroom was 1/10 of the former.
