1,1-Difluoroethylene / Vinylidene fluoride

[pitg]

Does 1,1-Difluoroethylene, Vinylidene fluoride (C2H2F2) considered as an oxidizing gas?
And does this gas included at acetylene group of gases?

 

[RaRo]

It is not an oxidant but reacts violently with one.
Regarding the explosion gas group, I would recommend you check with a flame arrester vendor.
For Amal (a manufacturer), it is in the IIA group (acetylene) as shown in their standard documentation.
