This class will provide a brief overview of the NIOSH Fire Fighter Fatality Investigation and Prevention Program. It will highlight the scope and objectives of the program and discuss the numerous fire service resources developed from the program’s LODD investigations. These resources include LODD reports, safety advisories, and workplace solutions. The class will also highlight critical information discovered in recent NIOSH LODD investigations. This information will go beyond the five most frequently cited LODD contributing factors of accountability, communications, incident management, risk assessment, and SOPs/SOGs. It will cover trending and prevalent contributing factors to include professional development, situational awareness, equipment application, structural collapse, and Mayday response. Recommendations on how to address each of those contributing factors will also be discussed.
