Commercial buildings present many challenges during a firefight, but knowing what they have to offer will make your job easier and safer. This class will review the built-in active and passive fire protection systems that make up the building's fire and life safety system and will give the participants an understanding of the basic working of said systems. Upon completion, participants will be able to return to their home departments and examine buildings and target hazards in their first-due response district and make changes to strategy and tactics, prefire plans, and battle plans. Firefighter safety is emphasized.
