Some Grade B fuel is classified into which two types?

Grade B fuel is primarily classified into volatile and non-volatile types. This classification is significant in the context of fuel handling and usage in maritime operations.

Volatile fuels, which have higher evaporation rates, can pose a risk of flammability and must be handled with care to minimize risks of fire and explosion. These fuels are often used in engines and systems where rapid combustion is needed.

Non-volatile fuels, on the other hand, have lower evaporation rates and are generally more stable at room temperature. They are less hazardous but may require different handling procedures, particularly in equipment or systems designed for combustion that necessitates specific conditions for efficiency.

Understanding the distinction between volatile and non-volatile fuels is essential for ensuring safety measures are in place to manage the risks associated with the different types of fuels used onboard vessels. This knowledge aids in proper storage, handling, and operational procedures to mitigate potential hazards effectively.
