🔍 Key Concepts

• Definition of a flammable liquid in maritime/hazardous materials regulations (flashpoint criteria) • Difference between flammable and combustible liquids • Typical flashpoints of common cargoes/fuels like gasoline, biodiesel, and various oils

💭 Think About

• Think about which substance on the list gives off ignitable vapors at the lowest temperature. • Ask yourself: which of these is typically treated as a high fire-risk fuel on small boats and ships? • Consider which materials are usually classed as oils or corrosives rather than as flammable liquids under shipping regulations.

✅ Before You Answer

• Verify the flashpoint range typically associated with a flammable liquid (in °F or °C). • Compare, in general terms, which option(s) are known to have a very low flashpoint versus those that are much higher or are mainly corrosive. • Confirm which items are commonly regulated or labeled as flammable liquid versus oil or caustic/corrosive cargo.
