Flammable and Combustible Liquids. What’s the Big Deal?
Ignite with explosive force Burn readily and give off
twice the heat as an ordinary combustible fire
Common materials people often take for granted or use carelessly

Examples of Flammable and Combustible Liquids
Flammable liquids Isopropyl alcohol Propane Solvents such as
acetone, MEK, paint thinner

Flashpoint
Lowest temperature at which a liquid gives off enough vapors to be ignited
Low Flashpoint = High flammability Flammable liquids have a flashpoint < 100˚ F Combustible liquids have a flashpoint > 100˚F
