Dry bulk cargo tanks are associated with Class 5: Oxidizers. This class includes substances that can cause or enhance the combustion of other materials. In the context of dry bulk cargo, oxidizers such as ammonium nitrate or potassium nitrate are commonly transported in bulk form.

Oxidizers are classified as substances that release oxygen when they decompose, which can greatly enhance the fire risk of other combustible materials. Therefore, understanding the properties of oxidizers and the specific requirements for transporting them in dry bulk cargo tanks is crucial for safety in hazardous materials operations.

In contrast, other classes relate to different types of materials: Class 2 includes gases, Class 4 encompasses flammable solids, and Class 6 pertains to toxic and infectious substances. Each class has distinct characteristics and regulatory requirements, but for dry bulk cargo tanks, the association with oxidizers clearly ties the hazard to Class 5.
