IATA Training Exam 2026/2027 – 40+ Questions & Correct Answers | Dangerous Goods, Category A & B Infectious Substances, UN 3373, Packing Instructions 620/650 & Dry Ice | IATA

This comprehensive IATA Training Exam 2026/2027 study guide contains 40+ exam questions with correct answers across 9 pages, providing focused preparation in the transportation of dangerous goods, particularly infectious substances and biological specimens transported by air. Core topics include dangerous goods training requirements, UN Model Regulations, air transport regulations, dangerous goods classification, Category A and Category B infectious substances, exempt patient specimens, triple packaging, UN numbers, proper shipping names, package testing, labeling and marking, emergency response, dry ice, and Packing Instructions 620, 650, and 954. The opening section focuses on dangerous goods regulations and personnel training requirements. Questions address function-specific training, safety training, general familiarization training, training records and certificates, the UN Sub-Committee of Experts (UNSCoE), and the comparatively restrictive requirements associated with air transportation. Students also review the information that must be documented following dangerous goods training and successful examinations. A major portion of the guide covers classification of infectious substances and biological specimens. The questions distinguish Category A infectious substances, Category B infectious substances, and exempt patient specimens while testing how different clinical materials should be classified for transportation. Examples include blood samples, stool specimens, urine specimens, cultures, potentially infectious animal specimens, and substances that have been neutralized or inactivated. The material also addresses relative infection risk and restrictions associated with transporting infectious substances. The document provides detailed revision of UN 3373 Biological Substance, Category B and Packing Instruction 650. Students review required package markings, shipper and consignee information, the UN 3373 diamond-on-point mark, proper shipping names, quantity limitations, placement of itemized contents, reusable packaging requirements, and package acceptance or rejection based on required marks and labels. Questions also cover solid Category B quantity limits and special provisions for organs and body parts. Another important section concentrates on triple packaging and package-performance requirements. The study material identifies primary receptacles, secondary packaging, and outer packaging and examines manufacturer closure instructions, interior supports, fibreboard packaging, water-spray conditioning, cold-temperature conditioning, and drop-testing requirements. These questions help students connect dangerous goods classification with the practical packaging requirements used to protect biological materials during transportation. The guide also covers dangerous goods documentation, identification, and emergency response. Students review proper shipping names, UN numbers, packing instruction numbers, special provisions, the Emergency Response Guidebook, yellow-page UN-number listings, and appropriate responses to spills or leaks involving liquid infectious substances. The document tests actions such as absorbing spills, covering damaged packages, and obtaining specialist supervision before attempting cleanup. The final section provides targeted preparation on dry ice and additional dangerous goods requirements. Questions cover UN 1845, the proper shipping names Dry ice and Carbon dioxide, solid, the Class 9 miscellaneous dangerous goods label, Special Provisions A48 and A805, Packing Instruction 954, preservatives permitted under Packing Instructions 620 and 650, and drop-testing requirements for de minimis quantity packages. For authoritative supplementary study, the most relevant professional reference is the IATA Dangerous Goods Regulations (DGR), particularly the provisions governing classification, packaging, marking, labeling, documentation, and air transport of infectious substances and dry ice. The subject matter also relates to the United Nations Recommendations on the Transport of Dangerous Goods – Model Regulations, which provides the broader international framework underlying dangerous goods classification and transport requirements. Relevant Students This document is particularly relevant for IATA dangerous goods training candidates, laboratory personnel, clinical laboratory students, healthcare workers shipping biological specimens, medical laboratory scientists, biomedical science students, research laboratory staff, specimen-transport personnel, logistics and cargo employees, airline cargo personnel, dangerous goods shippers, freight-forwarding staff, and professionals responsible for preparing infectious substances for air transportation. It is especially useful for learners reviewing Category A and Category B classification, UN 3373, triple packaging, Packing Instruction 650, dry ice shipments, dangerous goods markings, package testing, and emergency procedures.
