🔍 Key Concepts

• Flash point and what it tells you about how easily a liquid gives off vapors that can ignite • Difference between flash point, ignition temperature, and flammable range • General properties of Grade B combustible liquids in cargo/flammable liquid classifications

💭 Think About

• Ask yourself: which of these choices is directly about how readily a liquid forms ignitable vapor at relatively low temperatures? • Which option is a specific temperature at which vapor–air mixture will ignite from an external source, and which one is about the range of concentrations of vapor in air that will burn? • For Grade B products, what property is typically used to compare how "volatile" (vapor-producing) different liquids are?

✅ Before You Answer

• Be clear on the definition of flash point versus auto-ignition/ignition temperature • Confirm which properties are expressed as a single temperature and which as a range of percentages in air • Think about what a cargo officer would actually look up in a manual to compare the tendency of different cargoes to vaporize and form an ignitable mixture
