In this five-part series, based on his widely-adopted & bestselling text Collapse of Burning Buildings: A Guide to Fireground Safety, Deputy Chief Vincent Dunn shares his experiences and knowledge about size-up, specific collapse types, patterns that occur, warning signs, and dangers inside as well as outside the structure. Discussion questions are presented at the end of the program.
Part 1: Wall Collapse is based on observing hundreds of fires and describes how firefighters are as likely to get killed outside a burning building as inside, the different kinds of walls, the three ways they collapse, how far they fall, establishing danger zones, proper use of fire streams, flanking, responsibilities of officers, and more.
