Fire ventilation

Openings to gain access to a fi re that has spread into the
structure, for example in the walls or fl oor structure
This resembles and is therefore often confused with “venting
of a room exposed to fi re” and “venting of adjacent
rooms”. It is often implemented in connection with roof
fi res, or fi res in concealed spaces that cannot be reached in
any other way. The intention is in the fi rst instance to gain
access to and suppress the fi re inside the structure, not to
vent out smoke.
Venting for mopping up/salvage and overhaul
There is often a thin line between a fi re and rescue operation
and salvage and overhaul. Salvage and overhaul is often
started long before the fi re and rescue operation has been
completed in the legal sense. Salvage and overhaul is not
considered in any greater detail, however, in this book.
All these initial conditions fall under the collective concept
of fi re ventilation, since in the course of the practical
work in fi re and rescue operations they bear similarities or
are implemented side by side with each other in various
Opening to suppress or
prevent fi re spreading
in walls or fl oor
structures.
