This class focuses on the correlation between firefighter and civilian fatalities at the same structural fires. It quantifies basic risk vs. reward and goes beyond the tendency to justify risk whenever we respond to an occupied building. Size-up components, situational awareness, and calculating if civilians are savable before committing firefighters to an aggressive interior attack are discussed. Today's fire progression is discussed as a precursor to survival limits. The program concludes with fire scenarios and the appropriate firefighting strategies. The audience will have the opportunity to apply concepts and to discuss where and when interior fire operations should be focused on firefighting first and rescue/recovery operations second.
