Q

Which is a grade B flammable liquid?

🔍 Key Concepts

• Flammable liquid grades in cargo regulations (what properties define Grade A vs Grade B vs Grade C) • The difference between flammable liquids and flammable gases • Typical boiling point / vapor pressure and flash point ranges for each grade

💭 Think About

• First, separate which of the options are clearly liquids under normal conditions and which are primarily handled as gases • Think about which listed substances are known for extremely low flash points and very high volatility versus those that are nonflammable or only slightly flammable • Match the physical state and flammability of each substance to the usual grade definitions for flammable liquids

✅ Before You Answer

• Verify which of the listed substances is actually nonflammable and therefore cannot be a flammable liquid of any grade • Check which substances are usually classified as flammable gas, not liquid, under transport regulations • Confirm which remaining substance has properties (flash point/boiling point) that align with a Grade B flammable liquid definition
