Hexafluoropropane(HFC236fa)extinguishant stored in a cylinder is a kind of compressed liquefied gas, which is colorless, non-corrosive, non-conductive and non-destructive to ozone layer in the atmosphere. Hexafluoropropane (HFC236fa) extinguishant is an ideal substitute of Halon 1211, suitable to fill a protection, also suitable to the site having man of all flooding.

Packing

Filled in cylinders, each 1000kg net. Its category of dangerous goods is 2.2, and its packing category is second grade.

Security

The filled cylinder is under pressure, and ought to be avoider bumping, falling, exposure and heat sourse during transport and storage.
