Ceasefire inert gas suppression system uses inert or natural gases to extinguish fires. Often used as a blend of gases, these gaseous mixtures leave no residue behind and are designed to protect enclosures where there is a need for quick reaction to extinguishing a fire. A fire detection module is an integral part of these systems to trigger the gas suppression system.
The Basic Premise
The idea behind Ceasefire Inert Gas Fire System is to reduce the amount of oxygen present in the area where the fire breaks out. This is important because fires need oxygen in order to spread. Remove this vital element and the fire will be easier to contain.
While the oxygen level is lowered, the system does not eliminate oxygen from the space altogether. There is still enough Oxygen present to support proper breathing, as anyone in the immediate area moves along the escape route and exits the room.
What gases are used?
Ceasefire Inert Gas Suppression Systems use the following gases that reduce the concentration of Oxygen in the fire zone to kill fires.
CF1: CO2 (100%)
CF100: Nitrogen (100%)
CF541: A blend of Nitrogen(50%) + Argon(40%) + C02(10%)
CF01: Argon (100%)
CF55: A mix of Argon(50%) + Nitrogen(50%)
These inert gases are naturally occurring gases. We are surrounded by these gases. These gases reduce concentration of oxygen in the given space and extinguishes fire.
How is the Gas Deployed?
The Ceasefire Gaseous Fire Suppression systems can be configured for unique gas discharge options. Typically class "C" electrical fires require a minimum concentration while class "B" flammable liquid fires require a higher concentration or lowering of oxygen levels to put the fire out. Settling on the right approach depends on the type of environment in which the system will be used.
How does the system works?
The air we breathe has approximately 21% of Oxygen. Oxygen is the key factor in sustaining a fire and the key factor in keep us alive too!
By removing the oxygen, we will certainly extinguish a fire, but that comes with obvious problems. How do we sustain life at the same time?
Fires need more than 16% Oxygen to combust. Anything below this level of oxygen will not be enough for a fire to sustain combustion.
