New York City fire safety rules mandate that certain types of occupied structures employ qualified, certified fire safety directors to take responsibility for safety training, disaster preparation, evacuations, and other emergency responses. Individuals who want to become a certified fire and life safety director must meet certain qualification requirements and attend an approved F-89 fire and life safety director course to obtain their certification. International Security Services, Inc. (ISS) provides that critical training through the ISS Fire Science Institute in New York City.
