In Episode 19, check out UL FSRI Advisory Board Member, Cobb County Fire Department Captain, Sean Gray as he discusses attack line deployment when fire is showing remote from the primary entry point of the structure.
When arriving on the scene of a residential structure fire with remote fire showing, the initial attack line placement may have less to do with the proximity of the venting fire to the entry point and more to do with other variables on the fire scene such as the extent of fire advancement, obstructions to attack line deployment, need for forcible entry, weather, etc. For a room and contents fire, a priority is to cool the compartment and to knock the fire back before it extends beyond that room. There could be a scenario where that is achieved faster by conducting an interior attack through the front door, or a scenario where it could be faster to deploy the line to the remote venting fire. Whichever attack line deployment will allow for the fire to be knocked down faster may be the most effective tactical choice.
The tactical choice of an interior or transitional attack should be about timing to get water into the compartment.
Once initial water is applied into the compartment, the next tactical choice is how to most effectively get into the compartment to complete suppression. For some transitional attacks, you may be able to approach the vent and directly apply water to the burning contents; however, on others you may not. Similarly, for interior attack, some fires you can rapidly advance to the compartment after using the reach of your stream for initial suppression. Other times, interior conditions can prevent you from making rapid entry into the compartment. All of these factors should be considered together when making the choice on where to initially deploy the primary attack line.

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.
