What hazard class includes oxidizers?

The correct answer is that oxidizers fall under Class 5. This classification includes materials that can cause or enhance the combustion of other materials by yielding oxygen or similar substances. Oxidizers are substances that can lead to an increase in the intensity of a fire or explosion, which is why they are placed in this specific hazard class.

Understanding the importance of oxidizers is crucial for safety in hazardous materials handling, as they can react violently with combustible materials and pose significant risks during transportation and storage. This classification helps train personnel to recognize and manage the potential dangers associated with these materials effectively.
