A transitional fire attack is a combination of defensive and offensive techniques, that can only be used in very specific situations. It is known as a, “quick knockdown," from the exterior with a straight stream directed off the ceiling to hold a fire in check, and allows firefighters to perform an offensive fire attack under safer conditions for victims and for the fire attack crew.” The transitional fire attack is used when a structure fire has visible flames, from one or more openings. It is done to prevent the fire from reaching flashover, extend to uninvolved rooms, or extend to other nearby structures. If the location of the fire within a structure isn’t known, or an offensive attack can be made safely and effectively, a transitional attack isn’t appropriate and will not be used. A transitional attack is not based on the idea of unburned to burn, and push the fire back. The idea behind it is more along the lines of simply getting water on the fire, as quickly as possible. There are both advantages and disadvantages to this tactic. As mentioned above, the idea behind this tactic is to get water onto the fire as soon as possible. If this can be achieved, the fire will remain cooler, and more controlled for a limited amount of time. This can allow fire crews to search for, and rescue victims, locate power and utility shut off valves, and get a better understanding of the structure’s layout. There are some disadvantages to consider when using this tactic. The main issue is that it needs to be performed 100% correctly, or it is ineffective. If it is not done correctly, or in the appropriate situation, there is a great risk of pushing the fire. Temperatures could rise substantially, and smoke could fill adjacent rooms, or previously uninvolved areas. Defensive back up crews, and resources should be positioned in case they are needed, should the operation be unsuccessful. The situation could then deteriorate very quickly
