Under Division 6.2, which option is NOT a correct infectious substance category?

• A. Category A Substances
• B. Category B Substance
• C. Medical and clinical waste
• D. Ebola virus

Answer: (C)

The key idea is how Division 6.2 classifies infectious substances. It defines two main categories: Category A and Category B. Category A includes substances that can cause severe disease or death and require strict packaging and handling. Category B covers infectious substances that do not meet Category A criteria and are generally handled with standard precautions, using the Biological Substance, Category B designation (UN3373) for diagnostic specimens.

Ebola virus is a real example of a Category A infectious substance because it can cause a life-threatening illness. Category B applies to things like typical clinical or diagnostic specimens that are infectious but not as dangerous as Category A.

Medical and clinical waste, however, is not itself a defined infectious substance category within Division 6.2. It’s a type of material that may be regulated under separate waste management rules and may be treated to become non-infectious, or managed under different UN numbers depending on the situation. It isn’t a Category A or Category B designation, which is why it’s the option that isn’t a correct infectious substance category.
