FDNY fire marshals, who go into fire scenes after the blazes are extinguished, are considered law enforcement officers with the power to arrest those who commit arson and other crimes within New York City. Thus, fire marshals operate at the crossroads between detective work and the Fire Department. They sometimes also operated in tandem with federal investigators as well. Investigations by fire marshals provide critical information used by the department to improve the safety of FDNY members at fires and other emergencies and to provide fire causes that are used to direct fire safety education efforts for the public.
