Fire is getting faster
Because of synthetic materials, furniture, and construction, fire spreads faster than ever before. Closing doors helps stop the spread of fire.
Make a 900° difference
Research proves a closed door can mean the difference between 1,000 degress and 100 degrees in the event of a fire.
Take it down a notch
During a fire, a closed door can keep carbon monoxide levels at 1,000 PPM verses 10,000 PPM when a door is left open.
