Well, I just went and checked the alcohol-containing RV anti-freeze I have, and nowhere does have a "Flammable" on the label, and it does contain a certain percentage of ethyl alcohol. However it does say in small letters near the ingredients that it is "Combustible", which I think is considerably different from "Flammable".
The only difference between "Combustible" & "Flammable" is the flash point.
I also checked a couple of MSDS sheets for the two types of RV antifreeze. Both with the same freeze point rating.
Flash point for ethanol antifreeze - 110F.
Flash point for Propylene Glycol antifreeze - 228F.
FLAMMABLE VS. COMBUSTIBLE LIQUIDS
NFPA splits flammable liquids into two types: flammable and combustible.
Whereas OSHA only has one type: flammable liquids.
Either way, these are liquids that can burn, or rather, the vapor they give off can burn.
