5. CO2 - The Versatile Agent
Stored as a liquid
CO2 is stored as liquid, under pressure.
When a system is activated, the liquid CO2
flows through discharge pipe work to
specially designed nozzles.
Quick Vaporization
The agent’s low boiling point means that
the liquid vaporizes rapidly during the
discharge, providing a penetrative three-
dimensional action.
ROC Public: Green
6. CO2 - The Versatile 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 extinguished by
reducing the oxygen level in the risk area to the
point where combustion cannot be sustained.
Cools Area: Cooling is a secondary action of the
agent; this feature is used in local applications
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 action 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:
After extinguishing 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-conductive and so can be used on
energized electrical equipment.

10. CO2 - Over 60 years of Experience
Engineers developed carbon dioxide fire
extinguishing over 60 years ago and Kidde have
been responsible for every major improvement
that has been made in this branch of fire
protection.
Existing Products benefit from the accumulated
experience of thousands of installations in power
plants, industrial plants, oil refineries, electronic
processes, on ships and in a wide variety of
hazardous areas.

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 consideration
when frequent recharging of storage containers
is necessary as in local application systems,
where fires may be more frequent.

12. What is High Pressure Water Mist?
Basic principle:
WATER, discharged at HIGH PRESSURE
through SPECIAL NOZZLES
Resulting in VERY SMALL DROPLET SIZE and
HIGH DISCHARGE VELOCITY
ROC Public: Green
13. What is High Pressure Water Mist?
Asafe and fast alternative to CO2
A reliable alternative to inert gases
A clean alternative to foam
Anenvironmentally friendly alternative to halon
ROC Public: Green
14. High Pressure Water Mist
Safe alternative to CO2
CO2 has impact on central nervous system and heart functioning
Normal air has less than 0.1% CO2, normal breathing rate 25-30/min
0.5% is the safe limit for spaces occupied for less than 8 hours
Increase to 3% doubles the normal breathing rate, causes headache
12% consistency causes loss of consciousness rapidly and death in a couple
of minutes
CO2 fire protection systems’ consistency is min. 34%, and this consistency
should be attained within one minute (re. NFPA 12), and maintained over
the entire protection time (10-40 minutes).
Fine clean water mist produced by HI-FOG is safe
