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:
