A.Every 12 months

B.Every 24 months

C.Every 36 months

D.Only when regulations change significantly

C.5.0 kg (11.0 lbs)

D.Dry ice is completely forbidden in passenger baggage

Explanation: According to IATA DGR Section 2.3 (Table 2.3.A), passengers are permitted to carry up to 2.5 kg of dry ice in checked or carry-on baggage, provided the package permits the release of carbon dioxide gas and has operator approval.

A.Packing Group I

B.Packing Group II

C.Packing Group III

D.Packing Group IV

9What dangerous goods class does dry ice (UN 1845) belong to?

A.Class 2 (Gases)

B.Class 4 (Flammable solids)

C.Class 8 (Corrosives)

D.Class 9 (Miscellaneous dangerous goods)

Explanation: Dry ice (solid carbon dioxide) is classified under Class 9 (Miscellaneous dangerous goods) because it presents a hazard during air transport that is not covered by other classes (specifically, the release of carbon dioxide gas which can displace oxygen).

10Which division of Class 2 gases represents flammable gases?

A.Division 2.1

B.Division 2.2

C.Division 2.3

D.Division 2.4

About the IATA DGR (Air) Exam

The IATA Dangerous Goods Regulations (Air) Certification is the globally recognized industry standard for validating the competence of personnel who handle, offer for transport, accept, or load dangerous goods by air. Based on the ICAO Technical Instructions, the IATA DGR manual is updated annually to incorporate the latest safety standards, state/operator variations, and packaging rules. The examination is open-book and requires candidates to demonstrate proficiency in classifying dangerous goods into 9 classes, applying quantity limits on passenger and cargo aircraft, selecting correct packaging instructions (PI) and UN specification containers, applying hazard and handling labels, completing the Shipper's Declaration for Dangerous Goods (SDDG), and implementing stowage segregation and pilot notifications (NOTOC). Certification is valid for 24 months, after which recurrent training and re-examination are mandatory to maintain dangerous goods handling authority.

IATA DGR (Air) Study Tips from Top Performers

1Familiarize yourself with the layout and structure of the blue pages (Section 4.2 List of Dangerous Goods) so you can quickly search for UN numbers and proper shipping names under exam time limits.

2Practice referencing and calculating the lithium battery thresholds (Watt-hours for lithium-ion, lithium content in grams for lithium-metal) to determine if a shipment falls under Section IA, IB, or II.

3Pay close attention to Section 2.3 Passenger Provisions, as questions about passenger carry-on and checked baggage limits for toiletries, batteries, and dry ice appear frequently.

4Study Table 9.3.A (Segregation Table) carefully. You must be able to quickly determine if different classes of dangerous goods are allowed to be stowed together or require separation.

5Learn the detailed requirements of the Shipper's Declaration form. Make sure you can spot common errors like incorrect packing groups, misspelled proper shipping names, or missing signatures.

Frequently Asked Questions

What is the passing score for the IATA DGR exam?

Candidates must achieve a minimum score of 80% to pass the IATA DGR certification exam. This high threshold ensures that only personnel with an excellent grasp of aviation safety rules are certified to prepare or accept hazardous cargo.

How long is my IATA DGR certification valid?

The certificate is valid for 24 months (2 years) from the date of issue. To maintain your shipping or cargo handling authority, you must complete recurrent training and pass the exam again before your certificate expires.

Can I take the exam without the official DGR manual?

No. The IATA DGR exam is an open-book test that evaluates your ability to locate, interpret, and apply specific regulatory codes and values from the current edition of the DGR manual. Access to the manual is mandatory.

What is the difference between initial and recurrent DGR training?

Initial training is a comprehensive course for personnel who have not held a certificate before or whose certificate has expired. Recurrent training is a shorter, focused review course designed for currently certified individuals to refresh their skills and learn about annual regulatory updates.

Is my IATA certification recognized globally?

Yes. The IATA DGR is the global aviation industry standard recognized by airlines worldwide. However, you must also comply with any specific national rules (State Variations) of the countries of origin, transit, and destination.
