Normally, firefighters enter the front door of a structure to access a fire to extinguish it. This approach, enabled by the personal protective equipment firefighters wear, has provided positive results, especially if the firefighters can easily locate the fire from their point of entry. However, there have been many cases where the firefighters did not find fire. Instead, the fire found them. In fire incidents where firefighters were overtaken by the fire, the “one size fits all” fire attacks were not effective. Unfortunately, there are a number of these incidents where firefighters were killed or injured. In this presentation, the latest Underwriters Laboratories Fire Service Research Institute firefighting research results, supported by physics, are coupled with examples from fireground incidents to demonstrate why additional options are needed in your tactical tool box. Size-up, understanding what the fire is showing you, and then deciding the best strategic and tactical approach is key to an effective fire attack.
