In his stunning new book, American Sirens: The Incredible Story of the Black Men Who Became America's First Paramedics, former paramedic Kevin Hazzard explores the largely forgotten history of the Freedom House Ambulance Service. Hazzard joined the podcast to talk about his book, the early beginnings of EMS, and how a dedicated group of men from a downtrodden section of Pittsburg paved the way for a revolution in emergency medicine (1:56). Then, on a new Code Corner, NFPA engineer Robin Zevotek answers your questions about how to safely conduct live fire training (47:40).
