What is a good example of something classified as a Class B explosive?

A Class B explosive is characterized by its capability to produce a significant amount of gas and heat upon detonation or during a rapid chemical reaction. It often requires a detonator to initiate its explosive effect. Propellants, such as those used in rockets and some types of ammunition, fall into this category because they are designed to burn quickly and produce gases that exert pressure in a controlled manner, causing propulsion.

Firecrackers, black powder, and TNT each belong to different classifications. While black powder does have explosive properties, it is often categorized as a Class A explosive due to its lower sensitivity and the manner in which it deflagrates rather than detonates. TNT, while a well-known explosive, is categorized as a Class A explosive as well, given its higher stability and detonation characteristics compared to Class B explosives. Thus, the classification of propellant as a Class B explosive is accurate, emphasizing its role in producing controlled explosive reactions.
