Did you know that today, if your home broke out in fire, you would have less than three minutes to escape safely? But luckily, the simple action of closing your bedroom door before going to sleep can help slow the spread of smoke, heat and fire.

UL’s Fire Safety Research Institute launched the “Close Your Door” public service announcement to get this important fire safety tip out to as many families as possible.

“Something that came up again and again in our fire safety research was just how much safer the simulated occupant would be when they were behind a closed door,” said Steve Kerber, research director for UL’s Fire Safety Research Institute.

The campaign comes as a result of more than a decade of research by UL.

Forty years ago, a person had about 17 minutes to escape a burning home. Today, the time has dropped to three minutes or less. This is due to evolutions in furnishings, homes incorporating more open layouts, and lightweight construction materials, allowing fires to spread much quicker.

“Publicizing new fire safety techniques for preventing its spread are more essential today than ever,” said Kerber. “If you can get out of a burning structure, get out. If you can’t, put a closed door between you and the fire to buy yourself valuable time.”

A decade of research by UL found that closed-door bedrooms had an average temperature of 100 degrees Fahrenheit versus 1000+ degrees in the open-door rooms, indicating that a closed door kept room conditions survivable longer than an open door.

Consequently, when escaping a burning structure, it’s important to remember to close the door behind you to help limit property damage.
