Carbon Dioxide extinguishes fires by reducing the oxygen level below that which sustains combustion

Carbon Dioxide is an excellent extinguishing agent which extinguishes fire by reducing the oxygen level below that which will sustain combustion.

 Datasheet

Typical applications are:

• machinery spaces
• engine rooms
• electrical equipment rooms
• other unmanned applications

Advantages

• Naturally occurring gas
• Zero Ozone Depletion Potential
• Low agent cost
• Established technology
• Effective on deep seated fires
• Can be used to protect enclosed sections of a room such as the floor void
• No thermal breakdown products
• Safe for use on live electrical equipment

Disadvantages

• Health & Safety: Cannot be used under automatic control in manned areas
• Global Warming Potential
• Atmospheric lifetime
• High pressure storage (57.2 bars at 20C)
• High concentrations are required to effect extinguishing. As a result large numbers of cylinders are required, making it unsuitable for use where space and weight are important considerations
• Limited range of cylinder sizes
