How are infectious substances regulated under IATA DGR?

• A. They are classified as non-hazardous.
• B. They are classified as infectious substances (Category A or B) with specific packaging and labeling requirements.
• C. They are forbidden from air transport.
• D. They require no packaging.

Answer: (B)

Infectious substances are treated as dangerous goods that must be tightly controlled through classification and containment. Under IATA DGR, they are divided into two categories based on the risk and the conditions under which they can cause infection: Category A for substances known to cause infection when exposure occurs, and Category B for substances that are infectious but don’t meet Category A criteria. Once classified, these shipments require strict packaging and labeling to prevent leakage and exposure. This means using UN-specification packaging with a primary leak-proof container, a secondary protective container, absorbent material, and an outer packaging designed to withstand transport. In addition, clear hazard labeling and appropriate documentation are required so handlers and air carriers understand the risk and the correct handling procedures. Because of these dedicated requirements, infectious substances are regulated rather than considered non-hazardous, forbidden, or unpackaged. The correct answer reflects that they are categorized as infectious substances (Category A or B) with specific packaging and labeling requirements.
