There are many tactics for attacking structure fires. For years, the fire service has been preaching to attack from the unburned side. This isn't always the best tactic. The fireground is evolving more than ever before and with the use of research to enhance our procedures; this class will show tasks and tactics that can be used to be more efficient and effective in extinguishment. Using case studies paired with practical experience, this class will examine this particular fallacy along with others that have led to firefighters being injured and killed across the country from inefficient extinguishment. This class is against the grain of traditional firefighting and has an innovative approach at fighting the fires that we face today. Interior and exterior fire attack techniques will be discussed in detail and students will get an inside look into the future of UL-FSRI research into these topics and their importance for fireground success.
