Same thing.
Freon 13B1 is also known as Halon 1301 and is used in fire suppression systems.
Don’t the Russians know that freon is banned because it is a greenhouse gas and destroys the ozone! Where are the environazis when you need them...
I thought they outlawed Halon because it destroys the O-zone layer?
In a fire within a closed area the available oxygen will be consumed rapidly, a release of Halon gas will displace the remaining oxygen in a wave toward the floor while starving the flames.
A good engineer will allow for that factor and not overload the discharge beyond that which will support life (~19%) on accidental triggering.
One would die not from the poisionous amount of refrigerant gas but from asphyxiation, failing that.
Dumping Freon into a fire gives a LOT of very noxious extra fumes,, in addition to displacing O2 like you noted.
Must have been Halon and translated wrong (Though Halon is now prohibited (though a life-saver and a ship saver!) by the enviro’s because of the ozone).
If the Russians were using Freon (rather than Halon or even N2) the designers should be sent to a Siberian gold mine, where their talents are needed.
I wish the word Freon would get lost somewhere. Freon is a trade name by DuPont. Refrigerant is a better term. Phosgene {sp} gas is deadly. If it were a fluorocarbon type everyone would have likely died in a sub environment. Phosgene is a chemical reaction of burning Fluorocarbon refrigerants when mixed with certain other chemicals like propane. But even gasoline is actually a refrigerant.
The culprit sounds like Halon to me. Popular on surface ships where you can run to an oxygen source after activation. It's a push the button and you better run type system.
