The F# is used for identification purposes, and is usually placed on a firefighter’s personal protective equipment. This system originated under Chief William Comer who was assigned as F1. Below is a list of the initial numbers - of Chief's roster. It appears the F#s were given out in alphabetical order by rank not according to seniority as Deputy Chiefs Hancock (19654) and Walker (1956) appointments preceded DC Forbes (1960). Previous F numbers could be reused but presently each firefighter is issued a badge number and a unique F#.
Current PFD records us an "F000" system and list Chief John Mauro as F001. Since the original F#s appeared in a rank order, it is likely that Mauro "took over" the F1 or F001 when Comer retired.
The above numbers were slightly altered to fit the new scheme:
Edward J. Hancock F004
Joseph Roca F006
Dennis Digugliemo F008
George Asbaty F010
Albert Capter F011
At the turn of the 20th century the department began assigning F#s based upon a firefighters appointment date and thus they are currently in seniority order. They are never used again, even after a member retires. Badge numbers and F numbers are not related.
