Opening Doors and Taking Windows on the Fireground?

Consider your timing of these actions…

Study of Effectiveness of Fire Service Vertical Ventilation and Suppression Tactics in Single Family Homes (UL Research Report):

Control the Access Door:

"Tactically, there are several considerations for door control. Most importantly, it is a temporary action. You have to open a door to gain access into a burning home, but if you limit the air inlet you limit the fire’s ability to grow. The fire dynamics of door control are fairly simple. If you have a ventilation-limited fire and you limit the air, then you limit the heat that is able to be released. While this does not completely cut off the oxygen supply, it slows it, which slows fire growth. In these experiments, flashover was delayed for minutes by limiting the air supply. The longer and further the door is closed, the slower the fire will grow. The door should be controlled until water is applied to the fire. Once water goes on the fire and the attack crew has the upper hand, meaning more energy is being absorbed by the water than is being created by the fire, and then the door may be fully opened by firefighters to ventilate." (p.4)

Ventilation and Suppression efforts shall be coordinated!

A friend stated this “The fire doesn’t care if you take the wrong window or door or if it takes that opening, the fire will grow and consequences can occur.”

Let’s control the fireground by controlling the fire.

Stay Intelligently Aggressive!
