Shows 69 on-duty deaths in 2016. June 5, 2017 â The National Fire Protection Association (NFPA) released its annual U.S. Firefighter Fatalities report, which showed a total of 69 U.S. firefighter fatalities while on duty in 2016. This represents the fifth time in the past six years that the total number of deaths has been below 70. âWhen NFPA began reporting on firefighter deaths 40 years ago, the annual average was close to 150 fatalities per year. Over the past five years (between 2012 and 2016), the annual average has dropped to less than half that at 73 deaths, so weâve clearly seen a significant decline in on-duty firefighter fatality rates over time,â said Rita Fahy, NFPAâs manager of fire databases and systems.
