| all the 'd' extinguishers are quite expensive. aren't there any other economical extinguishers out there? or is everyone using lipos have these types of extinguishers which put out metal fires?

I doubt it. In all actuallity our lipos are very small. The Metals in them when they burn create their own oxygen. All A, B, C type extinguisher put out fires by removing air from the fire. Example Dry Chem smothers the fire (like a blanket). CO2 F.E. Simple displace Oxygen with CO2 plus it does "Cool" the fire which helps take away the heat from the fire triangle (Fire Triangle = Heat+Air+Fuel source= Fire). Halon Displaces air as well and also cools the fire a bit. Foam and electricity a big No No along with Water Extinguishers, since they conduct electricity.
D type extinguishers don't displace air. They simply wrap the fire so it doesn't spread. The fire Continues until it is burned out (I.E Fuel source is gone).
So to try to answer your Question, Since Lipo Metals in Batteries create there own oxygen when they burn, displacing air in theory won't work. However, Like the person talking about Halon working for him. It was displacing some air and cooling effects that might have won the fire fight (prolly the cooling effect). Our batteries are Small so the cooling effects of Halon, CO2 might be a good second option. If I was to choose, I would get a CO2, They are expensive up front, but recharging them is very cheep and they get colder than halon. The new Halon Chemical is Halotron and Clean Guard (Halotron is much better imo).
I would guess that Dry Chem prolly won't work worth a darn. But I haven't heard of anyone trying it to date. So I don't have facts to support that theory.
As for me, I don't have a "D" extinguisher, but i do have a 5# CO2 (type BC)and 4 dry chem (type ABC) extinguishers at my house, and one in the truck. |
