Flammable Organic Liquids:
Did You Know?
Many organic compounds are characterized as flammable even though the liquid itself will not burn. The vapor will burn. It is the combination of the creation of vapor and the addition of air that causes the substance to be flammable. You can conclude why cool storage of most organic liquids will lower your risk. Keep chemical storerooms cool and well ventilated.
