Carbon Dioxide Fire Extinguishing Systems typically store the agent in one of two different ways: in high pressure cylinders, or in low pressure CO₂ tanks.

Total flooding is the most common system application of fixed gaseous suppression systems and has been employed for the protection of volumes containing essential electronics Systems working on the total flooding principle apply an extinguishing agent to the entire volume of an enclosed area. These of systems are normally operated automatically by smoke detection when the area is unoccupied and manually by the operation of a system actuator when occupied. Due to the extreme density of the Carbon Dioxide, it quickly and effectively permeates the protected hazard area and suppresses the fire. Rapid expansion of Carbon Dioxide snow to gas reduces the ambient temperature in the protected hazard area which aids in the extinguishing process and retards re-ignition

With FM-200® gas, a combination of physical and chemical mechanisms combine at the surface of the flame to extinguishing the fire. The physical mechanism in the form of energy absorption predominates over the chemical mechanism. The chemical mechanism involves reacting with the transient combustion products stopping flame propagation.

FM-200® absorbs heat from the flame zone and interrupts the chemical chain reaction of the combustion process.

Stored as a liquid in cylinders, FM-200® flows through a piping network to a discharge nozzle where it is deployed as a gas.

FM-200® is non-conductive and non-corrosive so it's safe to use around all types of electronics and electrical equipment and has been proven safe for people.

ARGONITE® extinguishes fire by physically removing oxygen from the atmosphere. In occupied areas, people can breathe argonite at extinguishing concentrations without fear. There are no toxicological factors associated with the use of argonite and argonite will not decompose or produce any by-products when exposed to a flame from a fire condition.

INERGEN® is a mixture of nitrogen, argon and carbon dioxide, and has been specially developed to provide fire protection for sensitive electrical and electronic instruments and equipment.

INERGEN® reduces oxygen content to about 12.5 percent -- safely below the 15 percent level required for ordinary combustibles to burn, yet higher 10 percent level required for human safety.

INERGEN® is stored in gaseous form. It therefore does not produce fog when the gas is released into the room. No toxic decomposition products because INERGEN® is a mixture of naturally occurring gases; it does not form decomposition products in a fire.
