Which responsibility belongs primarily to the shipper of dangerous goods? A. Air traffic control B. Aircraft maintenance C. Packing the dangerous goods properly D. Airport security screening Correct Answer: C. Packing the dangerous goods properly Rationale: Shippers are responsible for correctly classifying, packaging, labeling, marking, and documenting dangerous goods shipments. 10. In the Emergency Response Guidebook (ERG), where are dangerous goods listed according to UN numbers? A. Blue pages B. Green pages C. Orange pages D. Yellow pages Correct Answer: D. Yellow pages Rationale: The yellow-bordered pages of the ERG list dangerous goods numerically by UN identification number. Blue pages list by proper shipping name, and orange pages provide emergency response guides. 11. The Emergency Response Guidebook identifies dangerous goods using which methods? A. Barcode numbers only B. Proper shipping names and UN numbers C. Driver identification numbers only D. Company inventory codes only Correct Answer: B. Proper shipping names and UN numbers Rationale: The ERG uses both proper shipping names and UN numbers to help responders identify hazardous materials quickly and accurately. Question 12: A shipment containing a leaking liquid infectious substance is discovered during transport. What is the most appropriate immediate response? A. Ignore the leak until arrival B. Attempt to clean the spill without protective equipment C. Absorb the spill and avoid cleanup unless supervised by a specialist D. Dispose of the package in regular waste Correct Answer: C. Absorb the spill and avoid cleanup unless supervised by a specialist Rationale: Infectious substance spills require careful containment procedures to prevent exposure and contamination. Absorbing the spill, covering damaged packages, and waiting for trained specialists minimizes risk to personnel and the environment. Attempting unsupervised cleanup or ignoring the spill could result in serious infection hazards. Question 13: Which information is included in the List of Dangerous Goods? A. UN numbers B. Packing instruction numbers C. Special provisions D. All of the above Correct Answer: D. All of the above Rationale: The List of Dangerous Goods provides comprehensive regulatory information, including UN numbers, proper shipping names, hazard classes, packing instructions, quantity limitations, and special provisions. This information guides shippers in preparing compliant dangerous goods shipments. Question 14: Under dangerous goods regulations, can infectious substances be transported in a passenger’s checked baggage? A. Yes, if properly sealed B. Yes, with airline approval C. Only if transported with dry ice D. No, infectious substances are prohibited in checked baggage Correct Answer: D. No, infectious substances are prohibited in checked baggage Rationale: Infectious substances are strictly prohibited in passenger checked baggage due to the significant health and safety risks they pose. Such substances require specialized packaging, labeling, documentation, and handling procedures that cannot be ensured in personal luggage. Question 15: How is a Category A infectious substance classified after it has been completely neutralized or inactivated? A. Category B infectious substance B. Exempt patient specimen C. Not regulated D. Toxic substance Correct Answer: C. Not regulated Rationale: Once an infectious substance has been neutralized or inactivated so that it no longer poses an infection risk, it is no longer regulated as a dangerous good. Regulations apply only when infectious properties capable of causing disease remain present. Question 16: A dead rat being shipped to a laboratory for possible Yersinia pestis testing would most likely be classified as: A. Exempt animal specimen B. Category B infectious substance C. Radioactive biological material D. Non-regulated waste Correct Answer: B. Category B infectious substance Rationale: Animal specimens reasonably expected to contain pathogens but not meeting the high-risk criteria for Category A are classified as Category B infectious substances. Yersinia pestis, the organism causing plague, presents infectious risk requiring regulated transport procedures. Question 17: A blood sample from a patient with unknown medical history sent for drug testing should generally be classified as: A. Category A infectious substance B. Exempt human specimen C. Category B infectious substance D. Corrosive substance Correct Answer: C. Category B infectious substance Rationale: Blood specimens from patients with unknown histories must be handled cautiously because they may contain infectious pathogens. Since the infectious risk cannot be ruled out, the sample is generally classified as Category B unless evidence supports exemption or Category A classification. Question 18: A stool sample submitted for testing for poliovirus is classified as which of the following? A. Exempt patient specimen B. Radioactive substance C. Category B infectious substance D. Corrosive material Correct Answer: C. Category B infectious substance Rationale: Stool samples being tested for infectious diseases such as poliovirus are regulated as Category B infectious substances because they may contain pathogens capable of causing disease in humans.

Biological substance, Category B C. Diagnostic specimen D. Category A infectious substance Correct Answer: D. Category A infectious substance Rationale: Category A infectious substances are capable of causing permanent disability, life-threatening illness, or fatal disease in otherwise healthy humans or animals upon exposure. Because of this severe risk, these materials are subject to the strictest packaging and transport requirements.
