The function and setting place of gas fire extinguishing system

The gas fire extinguishing system is based on some gaseous substances at normal temperature and pressure as the fire extinguishing medium, and the fire extinguishing concentration is established through these gases in the entire protection area or the local area around the protection object to achieve fire extinguishing. The system has fast fire extinguishing speed, high fire extinguishing efficiency, any dirt on the protected object, and no conduction, but the system has a large investment, can not extinguish the deep fire of solid matter, and the emission of some gas fire extinguishing agent has a certain impact on the atmospheric environment. Therefore, according to the performance characteristics of the gas fire extinguishing system, it is mainly used to protect important and require clean specific occasions, it is an important form of building fire extinguishing facilities.

The current national standards are "Code for Fire Protection Design of Buildings" (GB50016), Code for Fire protection Design of high-rise civil buildings "(GB50045)," Code for Fire Protection Design of civil air defense Engineering "(GB50098)," Code for Fire protection Design of garage and parking lot "(GB50067)," Code for Fire protection Design of steel and gold treatment Enterprises "(GB50414) Specific provisions are made for the installation sites of gas fire extinguishing systems. Therefore, the system should be set up in accordance with the relevant provisions of the current national standards.
