Total
flood fixed Gas
Suppression
Systems utilising
IG55 Inert Gas
Proinert ( Fike )
Argonite ( Ginge
Kerr Kidde )
Inergen ( Tyco )
or of the chemical
gasses, FM200,
FE25 ( Fike )
Novec 1230 ( Kidde
) all require
dedicated gas
extract systems to
ventilate the
released gas from
the protected
space to outside.
As the extract
requirement has
evolved since the
chemical gas Halon
days, British
Standards have
retained that
requirement for
all fixed gas
suppression
systems and in the
case of the
chemical gasses,
this remains an
established
requirement.
However, as the
extract was a
requirement to
remove possible
toxic products of
decomposed
chemical gas,
there is a
widespread
understanding with
Building Control
organisations and
indeed various
London Building
Control Officers,
that Inert Gasses
do not decompose
to any toxic
products and in
most cases using
inert gas, the
requirement to
provide a
dedicated extract
is avoided and
approvals gained
in that respect.
Inert gasses must
have gravity flap
unit over pressure
relief units. That
is not an item
associated with
the extract issues.
In many cases on
building
refurbishment and
fitout contracts,
there is a
mechanical
services
contractor who is
involved with
ventilation issues
and is therefore
best placed to
provide such
dedicated extract
systems, however,
careful
coordination is
required with that
contractor and
Gielle to meet the
requirements of
such extract
encompassing such
concerns as fan
location, damper
isolation
location, damper
actuation, point
of extract.
Gielle can advise
on all of these
matters. Just call
us on +39
080.3118998
In the case of
their not being
such facility of a
general
ventilation
contractor on
board within the
contract, then
Gielle are well
versed and able to
design, supply and
install,
commission such
systems as we also
have a good
mechanical
background and
understanding,
something that is
uncommon within
the fire industry.
