The Inergen gaseous system extinguishes fire without endangering people, property, or the environment because it is an inert gas fire suppressant made of natural gases. The benign gases nitrogen, argon, and carbon dioxide that naturally present in the air we all breathe make up Inergen, a patented unique composition that defeats fires rather than people. The INERGEN Fire Suppression System provides protection for enclosed spaces where there may be people, where fires might occur day or night, and where harm from conventional agents cannot be tolerated. When released, INERGEN agent fills the space and mixes with the air to swiftly and efficiently put out fires. INERGEN agent is non-synthetic and made of naturally occurring gases, making it safe for people.
