Definitions for "Combustible Liquid"
Any liquid having a flash point at or above 100° F and below 200° F under the conditions specified in Title 49, CFR.
Any liquid having a flashpoint at or above 100oF (37.8oC) but below 200oF (93.3oC).
A term used by NFPA, DOT, and others to classify certain liquids that will burn, on the basis of flash points. Both NFPA and DOT generally define "combustible" liquids" as having a flash point of 100°F (37.8°C) or higher. They do not ignite as easily as flammable liquids; however, they can be ignited under certain circumstances, and must be handled with caution. Class II liquids have flash points at or above 100°F but below 140oF. Class III liquids are subdivided into two subclasses: Class IIIA - Those having flash points at or above 140°F but below 2000F. Class IIIB - Those having flash points at or above 200°F.
