There are "bunker" programs around the US which allow college students to work in (and usually live in) firehouses. We know of only these at this time in NY State:
Onondaga Community College (315-469-2671) has opportunities for their fire science students to stay in fire stations in surrounding communities.
North Syracuse has a program for students headed to Syracuse Univ., LeMoyne, SUNY Oswego and Onondaga CC. Contact Capt Christopher Strong at email@example.com
A program is also in place at Schenectady Community College http://www.sunysccc.edu
Cortlandville FD has a program with SUNY Cortland (which again has no fire science program.)
Brighton (http://www.brightonfd.org/volunteer/ ).
If this interests you the Brighton Fire Department will host an informational meeting for student firefighters interested in joining our live-in program for the 2017-2018 academic year.The informational session will be held at Brighton Fire Station One (3100 East Avenue, Rochester) in March 2017 on a to-be-schedule Saturday morning at 11am.
