5. CO2
-­‐
The
VersaEle
Agent
• Stored
as
a
liquid
- CO2
is
stored
as
liquid,
under
pressure.
- When
a
system
is
acEvated,
the
liquid
CO2
flows
through
discharge
pipe
work
to
specially
designed
nozzles.
• Quick
VaporizaEon
- The
agent’s
low
boiling
point
means
that
the
liquid
vaporizes
rapidly
during
the
discharge,
providing
a
penetraEve
three-­‐
dimensional
acEon.

6. CO2
-­‐
The
VersaEle
Agent
• Reaches
difficult
areas
- The
rapid
expansion
of
the
gaseous
agent
allows
fires
to
be
targeted
even
in
the
most
inaccessible
areas
of
the
risk.
• Fights
fire
on
two
fronts
- Reduces
Oxygen:
Fire
is
exEnguished
by
reducing
the
oxygen
level
in
the
risk
area
to
the
point
where
combusEon
cannot
be
sustained.
- Cools
Area:
Cooling
is
a
secondary
acEon
of
the
agent;
this
feature
is
used
in
local
applicaEons
where
the
liquid
phase
of
the
discharge
is
applied
directly
to
the
fire
and
risk
materials.

7. CO2
-­‐
Fast
&
Efficient
• CO2
is
fast
and
efficient
- The
High
Pressure
CO2
system
uses
a
large
bore
discharge
valve,enabling
high
mass
flow
rates
to
be
achieved.
- The
fast
acEon
of
the
control
system
and
valve
enables
the
system
to
react
within
the
first
few
seconds
of
a
fire
that
can
make
the
difference
between
a
nuisance
and
a
disaster.

8. CO2
-­‐
A
Clean
Agent
• CO2
clean:
- CO2
is
a
colorless,
odorless,
dry,
inert
gas
and
is
one
of
the
most
familiar
of
all
chemicals.
• No
residue:
- AXer
exEnguishing
a
fire
it
vaporizes
fully
leaving
no
residue.
There
is
no
mess,
nothing
to
clear
up,
no
water
damage.
• Safe
to
use
on
food:
- It
is
non-­‐corrosive
and
will
not
contaminate
foodstuffs.
ROC Public: Green

9. CO2
-­‐
A
Clean
Agent
• Safe
for
electrical
fires:
- It
is
non-­‐conducEve
and
so
can
be
used
on
energized
electrical
equipment.

electronic

and
in
a

11. CO2
is
Low
Cost
• Carbon
dioxide
is
a
standard
commercial
product
with
many
other
uses
and
it
is
readily
available
throughout
the
world.
• Because
of
its
universal
use
it
can
be
obtained
cheaply
and
this
is
an
important
considera5on
when
frequent
recharging
of
storage
containers
is
necessary
as
in
local
applica5on
systems,
where
fires
may
be
more
frequent.
