CO² Fire Suppression Systems
CO² Fire Suppression Systems
The rapid expansion of this gaseous agent allows fires to be targetted even in the most inaccessible areas of the risk.
CO² leaves no residue behind…
Carbon Dioxide is a standard commercial product with many other uses and is readily available throughout the world.
Because of its universal use, it can be obtained inexpensively – this is an important consideration when frequent recharging of storage containers is necessary such as in local application systems, where fires may occur frequently.
CO2 is stored as liquid, under its own vapour pressure of ~59 bar at 21°C. The agent’s low boiling point means that the liquid vaporises rapidly during the discharge, providing a penetrative three-dimensional action.
It is generally specified in locations where people will not be working, since it is hazardous to humans in the concentrations deployed by fire suppression systems.
CO2 is colourless and odourless. After extinguishing a fire, it vaporises fully leaving no residue. With non-conductive properties it can be used on energised electrical equipment and safely used to protect delicate electronic equipment, antiquities or archive materials.
Total flooding systems extinguish fires by rapidly discharging CO² into an enclosed volume to create an atmosphere that is incapable of supporting combustion. This concentration of CO² presents a serious hazard to personnel and under no circumstances should CO² be released into areas that may be manned at the time of discharge.
IPH Fire Solutions can offer time delays, isolating valves including distribution valves and control head lockout pins to facilitate the safe use of CO²
This method of system design is used to protect hazards that are open or have only partial enclosure, situated within a larger area that would be unsafe or uneconomic to protect using a total flood system. Discharge nozzles are placed to provide direct agent flow at the points and areas prone to fire.
The wide range of components manufactured by IPH Fire Solutions long established suppliers, enables systems to be either automatically or manually operated, arranged to protect single or multi-zone hazards and supplemented with a reserve discharge facility. Automatic control can be achieved mechanically, pneumatically, electrically or by any combination of these to suit site conditions.
Facilities are available for providing a pre-alarm and delayed discharge as well as various methods of preventing automatic release while protected rooms are occupied by personnel.
How often must CO2 cylinders be tested??
All DOT-3AL marked CO2 cylinders are to be inspected and hydrostatically re-tested every five years as required in CFR Title 49 Part 180.205(c). Cylinders still with charge at the time the 5 year re-test is due, do not have to be re-tested until the charge is used, but prior to the re-filling of the cylinders.
Is CO2 gas dangerous?
How does a CO2 Fire System work?
A fire needs oxygen, fuel, and heat to continue to burn. When the suppression system detects smoke or fire, it then releases the CO2 agent into the space it is protecting.
The CO2 level in the space quickly increases as the oxygen level quickly drops causing the fire to be suppressed or extinguished.
At what level does CO2 become toxic?
1000 to 2000 ppm, the air quality is low. From 2000 to 5000 ppm, CO2 concentration starts to cause problems (headaches, insomnia, nausea). It is a dirty air.
From 5000 ppm, the presence of other gases in air is altered, arising a toxic atmosphere or poor in oxigen with fatal effects as the concentration increases.
