All FDNY ladder co.'s have members split into inside team and outside team.
Inside team consists of Officer, Forcible Entry man, Can man they go to the assigned floor, which could be the fire floor or floor above , for finding fire location and search for victims.
The outside team consists of the OVM outside vent man who posistions him self to the rear or opposite the fire to provide Vent, Enter, Search many times working on the fire escape of the fire appartment or working off of a portable ladder. The Roof man who provides Vertical Venting at the roof level , exception is fire resistant buildings were his duties change to operations on the floor above the fire.
The Chauffer who has the responsibility of the front of the fire building usually working off the aireal ladder for Vent,Enter , Search. These are the basic duties of these ladder co. posistions which can vary depending on the building type. Hope this was helpfull.
