What does a low flashpoint indicate about a liquid?

A low flashpoint indicates that a liquid can easily ignite and produce vapors. The flashpoint is the lowest temperature at which the vapor of a liquid can ignite in the presence of an ignition source. Thus, a liquid with a low flashpoint releases vapor at lower temperatures, increasing the risk of combustion. These vapors can easily form combustible mixtures with air, which is why liquids with low flashpoints are often classified as flammable and require careful handling and storage to prevent accidental ignition.

In contrast, a low flashpoint does not imply safety in storage, as such liquids can be dangerous and require specific conditions to minimize risk. Additionally, having a low flashpoint does not relate to the boiling point of the liquid or its stability under extreme temperatures, as these factors are independent of the flashpoint measurement.
