In the classification of fuels by the Coast Guard, which letter is NOT included?

In the classification of fuels utilized by the Coast Guard, fuels are categorized into various classes denoted by letters. Each class represents different types of fuels and their specific characteristics that are relevant for operational safety and environmental protection. The classification system includes classes A, B, D, and E.

Class A typically refers to flammable liquids with a flash point below 100°F, which are critical for safety considerations. Class B usually involves combustible liquids that have a higher flash point. Class D generally pertains to non-flammable liquids, which have specific handling and storage protocols. Class E is designated for other types of fuels that do not fall into the aforementioned classes.

The inclusion of these classes reflects the need for a comprehensive understanding of fuel properties in maritime operations to ensure adherence to safety standards and environmental regulations. Class F is not recognized within the Coast Guard’s classification system and thus, it is the choice that is not included in the listings.
