What class or division number is assigned to infectious substances?

• A. 6.2
• B. 3
• C. 4
• D. 9

Answer: (A)

In dangerous goods classifications, infectious substances sit in Class 6.2. The 6 identifies toxic and infectious substances, and the sub-division 2 specifies infectious substances. That’s why this option is the best choice. The other numbers point to different hazard classes—3 is flammable liquids, 4 is flammable solids, and 9 covers miscellaneous dangerous goods. For infectious substances, you’ll also encounter categories like Category A or Category B within 6.2, which affect packaging and labeling, but the class/division used for shipping is 6.2.
