Today, we are rethinking everything you know about fire ground size-up. Everyone has been taught standard acronyms like COAL WAS WEALTH. But that traditional method is often too complicated for a young firefighter or inexperienced officer with no background in building construction.

Our guest today is here to share what he calls a system for success. He breaks down the vital difference between an initial windshield report and a true size-up. And he warns that a worthwhile size-up absolutely does not take place from the cab of the apparatus.

Todd Edwards explains why identifying the occupancy is the most critical step. Hearing "working fire" over the radio is simply not enough for incoming units to make tactical decisions. They need to know exactly what they are dealing with before they ever step off the rig.

Todd Edwards served for over 30 years with Atlanta Fire Rescue. He is a second-generation firefighter and the creator of the presentation "Size-Up: A System for Success." During his career with Atlanta, he held a variety of positions, including Captain, Battalion Chief, and Assistant Fire Chief.
