2 GENERAL DESCRIPTION.

2.1.1 Carbon dioxide high pressure system.

Carbon dioxide is a colourless, odourless, electrically non-conductive gas that is a suitable

medium for extinguishing fires. Liquid carbon dioxide forms dry ice snow when released

directly into the atmosphere.

Physical properties: Molecular weight 44,0

Density at 0 OC/1 Bar 2,0 kg/m3

Specific gravity 1,5

1 kg CO2 = 0,56m3 at 1 atm.

Carbon dioxide extinguishes fire by reducing the oxygen level, the vapour phase of the fuel or

both in the air to the point where combustion stops. Carbon dioxide is present in the

atmosphere at an average of 0,03 % per m3. It is also a normal end product of human and

animal metabolism. Carbon dioxide influence certain vital functions in a number of important

ways, including control of respiration, dilation and constriction of the vascular system -

particularly the cerebrum and the pH value of the body.

The concentration of carbon dioxide in the air governs the rate at which carbon dioxide is

released from the lungs at thus affects the concentration of carbon dioxide in the blood and

tissues. An increased concentration of carbon dioxide in air can, therefore, become

dangerous due to a reduction in the rate of release of carbon dioxide from the lungs and

decrease oxygen intake.

2.1.2 Use limitations.

Carbon dioxide fire extinguishing systems are useful to extinguish fires in specific hazards

areas, and in occupancies where an inert electrically non-conductive medium is essential or

desirable.

Some of the most important types of hazards and equipment that carbon dioxide systems

protect, may include:

- Flammable liquid materials.

- Electrical hazards, such as transformers, oil switches and circuit breakers, rotating

equipment, and electronic equipment.

- Engines utilising gasoline and other flammable liquid fuels.

- Ordinary combustibles such as paper, wood and textiles.

- Hazardous solids.

The discharge of liquid carbon dioxide is known to produce electrostatic charges which,

under certain conditions, could create a spark. Carbon dioxide fire extinguishing systems

protecting areas where explosive atmosphere could exist shall utilise metal nozzles and shall

be properly grounded. In addition, objects exposed to discharge from carbon dioxide nozzles

shall be grounded to dissipate possible electrostatic charges.

Carbon dioxide will not extinguish fires where the following materials are actively involved in

the combustion process:

- Chemicals containing their own oxygen supply, such as cellulose nitrate.

- Reactive metals such as sodium, potassium, magnesium, titanium and zirconium.

General Description.

CO2-High Pressure Multiple Area Pneumatic

- Metal hydrides.

- The CO2 fire extinguishing effect will be reduced by fire in wood, paper and textile.

Note. The system is only to be used for fire extinguishing and not for other purposes,

due to the electrostatic ignition hazard.

2.1.3 Quality

Carbon dioxide used for initial supply and replenishment must be of good commercial

grade, free of water and other contaminants that might cause container corrosion or interfere

with free discharge through nozzle orifices. In general carbon dioxide obtained by converting

dry ice to liquid will not be satisfactory unless it is properly processed to remove excess water

and oil.

2.1.4 Types of fires.

Surface fires are the most common hazard particularly, adaptable to extinguishing by total

flooding systems. They are subject to prompt extinguishing when carbon dioxide is quickly

introduced into the enclosure in sufficient quantity to overcome leakage and provide an

extinguishing concentration for the particular material involved.

For deep-seated fires, the required extinguishing concentration shall be maintained for a

sufficient period of time to allow the smouldering to be extinguished and the material to cool

down to a point at which re-ignition will not occur when the inert atmosphere is dissipated.

It is necessary to inspect the hazard in every event immediately thereafter to make sure that

the extinguishing is complete and to remove any material involved in the fire. Where the

quantity of extinguishing medium is required to protect more than one space, the quantity of

the medium available does not have to be more than the largest quantity required.

2.1.5 CO2 - Cylinder Bank.

The fire-extinguishing medium shall be stored in a room that is situated in a safe and

accessible position and shall be effectively ventilated to the satisfaction of the Authorities.

Any entrance to such a storage room must preferably be from the open deck and in any case

shall be independent of the protected space. Access doors shall open outwards, and

bulkheads walls and deck including doors and other means of closing any opening therein,

which from the boundaries between such rooms and adjoining enclosed spaces must be gas

tight.

2.1.6 Leakage and Ventilation.

Since the efficiency of carbon dioxide systems depends upon the maintenance of the

extinguishing concentration of carbon dioxide, leakage of gas from the space shall be kept to

a minimum and compensated for by applying extra gas where required. Means shall be

provided to close all openings, which can admit air to or allow gas to escape from a protected

space.

2.1.7 Personal protection and safety aspects.

The CO2 - gas reduce the human ability to utilise oxygen from the air, and becomes gradually

more dangerous with increased concentration.

General Description.

CO2-High Pressure Multiple Area Pneumatic

Autronica Fire and Security AS

Page 4

CO2 concentration up to 6-7 % of the net volume is normally harmless to most people, but

should be avoided.

The CO2 concentration after one discharge of the fire extinguishing system will be minimum

30 % of the net volume, and will be fatal for human.

Means shall be provided for automatically giving audible warning the release of fire-

extinguishing medium into any space in which personnel normally works or to which they

have access. The alarm shall be operated for a suitable period before the medium is

released.
