In Episode 5, check out UL FSRI Director, Steve Kerber, as he focuses on how fire development changes when a fire becomes ventilation limited:

One of the first things every firefighter learns about fire is the fire triangle. Fire needs fuel, heat and oxygen to survive.

Fire growth is definitely related to the amount of fuel and heat that is available, but it is the amount of oxygen that is making the difference in how fast the fire is allowed to release heat. Control the oxygen, and you have control of the fire.

This series of videos will bring you tactical considerations from firefighter research and will feature members of the UL FSRI team and Advisory Board.

A Tactical Consideration is an evidence based concept for the fire service to consider implementing into their department to enhance efficiency, effectiveness, and increase knowledge to accomplish their mission. With all of the measurements made during UL FSRI experiments as well as the vast experience of our project technical panels, several consistent themes have emerged that may be helpful to the fire service. Each of these themes is packaged as a tactical consideration with supporting text and visuals.

The application of tactical considerations depends upon many factors such as:

  • building structure and geometry
  • capabilities and resources available to the first responding fire department
  • availability of mutual aid

There is no silver bullet tactic for structure fires and these considerations are meant to increase the knowledge of the fire service and to be incorporated into training and procedures, if deemed applicable.
