Heptafluoropropane Fm200 Fire Extinguishing System For 120L Cabinet
Is heptafluoropropane harmful to the human body? Gas fire extinguishing manufacturers deeply analyze the characteristics of heptafluoropropane for you
First of all, as a type of gas fire extinguishing system, heptafluoropropane has been favored by the majority of users for its high fire extinguishing performance and the characteristics of no secondary pollution. Secondly, with the country's emphasis on fire protection, heptafluoropropane fire extinguishing system has gradually become an essential fire-fighting equipment in key protection places such as computer rooms, power distribution rooms, archives rooms, important databases, containers, etc. However, when the editor received customers, he found that the customers were still very concerned about the issue of "whether heptafluoropropane is harmful to the human body". So today we will talk about this issue in detail.
What is heptafluoropropane? According to GB18614, Heptafluoropropane (HFC227ea) Fire Extinguishing Agent, heptafluoropropane should be named 1,1,1,2,3,3,3-heptafluoropropane according to my country's chemical system nomenclature. It is called HFC227ea according to the international general nomenclature of halogenated hydrocarbons. It is also called HFC-227, FE-227 and FM-200. Its chemical formula is C3HF7, its melting point is 131℃, its boiling point is 16.4℃, it is slightly soluble in water (260mg/L), it is a colorless and odorless gas, its relative molecular mass is 170, its density is about 6 times that of air, it is stored in high-pressure liquefaction, it has good thermal stability and chemical stability, its ozone depletion potential ODP is 0, its greenhouse effect potential GWP is 3500, but it stays in the atmosphere for a short time.
The principle of HFC-227ea gas fire extinguishing is mainly to inhibit chemical chain reaction and partial physical cooling. It can extinguish fire on solid surface, and has good fire extinguishing effect on flammable liquid fire or meltable solid fire, flammable gas fire that can cut off the gas source before extinguishing. There is no pollution loss to the protected property, especially suitable for protecting special items such as precision instruments, data processing centers and precious cultural relics that require fast fire extinguishing speed, non-conductive and non-corrosive.
Toxicity of heptafluoropropane itself:
Around 1994, a relatively comprehensive and systematic study of heptafluoropropane fire extinguishing agent was conducted in China using mice, rabbits, dogs, and human volunteers. The test results show that heptafluoropropane itself is low-toxic or non-toxic, and inhalation can be considered non-toxic. The toxicity characteristics of heptafluoropropane are as follows:
