Explanation

In a data center, it's critical to choose a fire suppression system that protects both the hardware and the environment. An inert gas fire suppression system is an environmentally friendly and effective method for suppressing fires in data centers because it uses gases like argon, nitrogen, or carbon dioxide that do not harm sensitive electronic equipment. These gases work by reducing the oxygen levels in the protected area to the point where combustion is no longer sustainable, without causing harm to the environment. Inert gas systems are preferable in environments like data centers because: They are non-toxic to humans in moderate concentrations (although people must evacuate before levels drop too low). They do not leave residue or cause damage to electronic equipment, unlike water-based systems that can cause corrosion. They have a low environmental impact, especially compared to older systems like Halon.
