The principal basis for classification of flammable liquids is:
A)flashpoint
B)firepoint
C)volatility
D)autoignition temperature

Question

Quizplus · Accepted Answer

The flashpoint of a liquid is the temperature at which it gives off enough vapor to ignite in the presence of an ignition source. This is the most important characteristic for safety reasons since it determines the hazard class of a flammable liquid, as well as its proper storage, handling, and use. Firepoint is the temperature at which the liquid continuously burns when ignited, and is not used for classification purposes. Volatility is a measure of how easily a liquid turns into a vapor, and is related to its evaporation rate, but does not directly indicate its flammability. Autoignition temperature is the temperature at which a liquid spontaneously ignites without a spark or flame, and is not used for classification purposes.
