Fighting Fire with Science

Close Your Door comes as the result of over 10 years of research by the UL Firefighter Safety Research Institute (FSRI). After proving that a closed door could potentially save lives in a fire, UL FSRI has committed to share this finding with the world.

The Difference a Door Makes

In tests, a closed door made a potentially life-saving difference in a fire.

Closed Door Room

  • More Survivable Temp: < 100°
  • Livable 18% Oxygen Level
  • Less Toxic Carbon Monoxide Levels: 100 PPM CO (parts per million of Carbon Monoxide)

Opened Door Room

  • Less Survivable Temp: > 1,000°
  • Low 8% Oxygen Level
  • Extremely Toxic Carbon Monoxide Levels: 10,000 PPM CO

Close your bedroom door at night

About half of home fire deaths result from fires reported between 11 p.m. and 7 a.m., when most people are asleep. The bedroom door is a barrier that could save your life.*

Don’t Forget the Front Door!

Even when exiting a burning structure, close the door behind you. It will cut off the oxygen supply and may stop fire’s growth.
