CO2 Fire Suppression Systems
· Versatile· Fast & Efficient· Clean· Low Cost
ROC Public: Green
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
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.

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.

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
CO2 - A Clean Agent
· Safe for electrical fires:- It is non-conductive and so can be used on
energized electrical equipment.

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.

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.

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
A safe and fast alternative to CO2
A reliable alternative to inert gases
A clean alternative to foam
An environmentally friendly alternative to
halon
What is High Pressure Water Mist?
ROC Public: Green
· 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

Gas Turbine Protection
· Water mist system
ROC Public: Green
· Typically 2 or 4 spray heads
· Small diameter single tube to each spray head
· Spray heads mounted parallel to turbine axis
· In accessory spaces spray heads can be mounted on ceiling

ROC Public: Green
· Fuel oil or lubrication oil fire starts in turbine enclosure
· Fuel supply is shut off
· Forced ventilation is shut down
· System is activated by the detection system
· Lube oil is provided during coast down or longer
· An open door or vent does not impair extinguishing capability
