Gaseous fire suppression, also called clean agent fire suppression, is the use of inert gases and chemical agents to extinguish a fire. These agents are governed by the National Fire Protection Association (NFPA) Standard for Clean Agent Fire Extinguishing Systems – NFPA 2001 in the US, with different standards and regulations elsewhere.
Cylinders containing argon gas for use in extinguishing fire without damaging server equipment. Argon has several desirable properties: Argon is a chemically inert gas. Argon is the cheapest alternative when nitrogen is not sufficiently inert. Argon has low thermal conductivity.
It is generally used in situations where water from a fire sprinkler would damage expensive equipment, or where water-based fire protection is impractical, such as museums, banks, clean rooms and hospitals. The HFC-125 clean agent is stored in a pressurized container and introduced into the hazard as a gas.
Halon systems are among the most effective and commonly used fire protection systems used on commercial aircraft. Halon 1301 is the primary agent used in commercial aviation engine, cargo compartments, and auxiliary power unit fire zones. [9] [10] Efforts to find a suitable replacement for Halon 1301 have not produced a widely accepted replacement.
Engineered fire suppression systems are design specific and most commonly used for larger installations where the system is designed for a particular application. Examples include large marine and land vehicle applications, server rooms, public and private buildings, industrial paint lines, dip tanks and electrical switch rooms.
Halotron I is a fire extinguishing agent primarily composed of a raw material HCFC-123 (93%), mixed with tetrafluoromethane and argon serving as propellants. Global emission concerns [ edit ]
