Welcome to the new IPSDI Exposure Tracker. Developed by the International Public Safety Data Institute (IPSDI), a leading research and training organization dedicated to advancing public safety through data science, this app provides firefighters with powerful tools to track their individual exposures and keep a record of them should they ever need it.
