A
roof training site has been constructed behind the Private
Dwelling building. This structure includes the fly section
of an aerial ladder to provide roof access and the usual
skylight, scuttle cover and gooseneck ladder in the
rear. It duplicates the roof of a tenement.
There are two typical precut holes
in the roof. The covering of the roof is three layers
of membrane type that is now widely in use.
Beneath
the skylight, scuttle cover and roof cuts are ducts
positioned to distribute "smoke" to each area
during venting procedures. Saw operations involve operating
the saw blade around existing saw cuts, but 2x4 inch
roof members are inserted adjacent to the 3x10 inch
roof rafters.
This technique allows firefighters
to operate the saw and actually cut and remove the membrane
covering, and the 1x6 inch roof boards. The "smoke"
pushing out around the cut appears quite realistic.
Decisions and procedures affecting
roof operations will be reviewed by our tactical training
officers.
