The environment known as the fireground is a dynamic, deadly, and increasingly complex arrangement of almost limitless variables. Firefighters are facing even greater challenges with the advancement of lithium-ion batteries in homes and cars, and more synthetic fuels being used in the construction and contents of the building itself. It is of the utmost importance that firefighters do not enter a structure without a plan based on training, experience, and fireground data. We remind the public each year to water their Christmas tree to prevent a possible fire but firefighters fail to water the couch (or any furniture) as they pass this potential fuel source that is rapidly off-gassing highly flammable vapors. There are many firefighters who are opening the nozzle on the way to the fire, but our research has shown that the majority of these fire suppression efforts are brief short bursts or improper penciling techniques. This course will provide factual data about the value of an open and flowing nozzle. Firefighters need to understand that our efforts should be improving conditions. Proper water application applied early and consistently moving towards the seat of the fire reduces overall temperatures, increases chances for victim survival, and reduces the risk of rapid fire development. This presentation provides data, research, and video demonstrations to open up the attendees’ paradigm about "fire attack" and how we can better fulfill the oath of saving lives and property.
