G.6.a. Advantages
The firefighter 1-in-3 duty rotation provides for an average of 56 work
hours (i.e., 56 duty hours) and 112 hours of liberty each week. This
section also provides the following advantages:
(01)
(02)
All duty standers are “professional” duty standers (i.e., duty is all
they do).
Exceptional quality of life for all unit personnel – duty standers
only work 7 out of 21 days).
(03) The potential for duty crews exceeding fatigue standards is
minimized.
(04) Non-duty standing personnel (i.e., maintenance and support
personnel) can work a normal workweek.
G.6.b.
Disadvantages
The firefighter 1-in-3 duty rotation requires more non-duty standing
positions than more traditional duty rotations. This rotation also includes
the following disadvantages:
(01) The duty section must accomplish all training.
(02) Potential for operational tasking outside of scheduled work hours
(unless non-response crews are available).
(03) All-hands evolutions not easily accommodated.
