IATA DGR 67th Ed. Section 9.3 — Loading restrictions, cargo compartment classification, segregation requirements, and special stowage rules for dangerous goods in air transport.
9.3.1 Loading Restrictions on Flight Deck and Passenger Aircraft
9.3.1.1 Dangerous goods must not be carried in an aircraft cabin occupied by passengers or on the flight deck, except as permitted by 2.3.2 to 2.3.5 and 2.5.1, and for excepted packages of radioactive materials (10.5.8).
Dangerous goods may be carried in a main deck cargo compartment of a passenger aircraft provided the compartment meets all certification requirements for a Class B or Class C aircraft cargo compartment.
9.3.1.1 (cont.) Packages bearing the "Cargo Aircraft Only" label must not be carried on a passenger aircraft.
State Variations: JPG-10/12, USG-13/15 | Operator Variations: BR-16, IR-04, P3-01, SQ-01, SW-01
Cargo Compartment Classification (A / B / C / D / E)
| Class | Description |
|---|---|
| A | Accessible to crew during flight. Fire can be detected and extinguished by a crew member using a hand-held extinguisher. |
| B | Accessible to crew. Has a built-in smoke/fire detector and sufficient access for the crew to effectively reach any part of the compartment with a hand-held extinguisher. |
| C | Not accessible to crew. Has a built-in smoke/fire detector and fire suppression system that can be activated from the flight deck or a station. |
| D | A compartment in which a fire is completely confined without endangering the safety of the aircraft or occupants. Completely fire resistant. (No longer used in new aircraft designs.) |
| E | Cargo compartment on the main deck of an all-cargo aircraft that has a smoke/fire detector but does not require fire suppression (lower lobe accessible to crew). |
Cargo compartment classification definitions per Appendix A (Glossary) of the IATA DGR 67th Ed.
9.3.3 Handling and Loading of Packages Containing Liquid Dangerous Goods
Packages containing liquid dangerous goods must be loaded with closures upward and in accordance with the orientation arrows ("This Way Up" labels) on the package.
Single packagings with closures on the side must be loaded with closures upward. Where this is not practicable, they must be loaded so that the closure is facing inward and not toward the aircraft skin.
Operator Variations: CI-04, KE-07
9.3.2 Incompatible Dangerous Goods — Segregation
9.3.2.1.1 Packages containing dangerous goods which might react dangerously with each other must not be stowed on an aircraft next to each other or in a position that would allow interaction in the event of leakage. The segregation requirements shown in Table 9.3.A must be observed. These apply based on all hazard labels on the package, irrespective of primary or subsidiary hazard.
Table 9.3.A — Segregation of Packages
| Hazard Label | 1 excl. 1.4S | 2.1 | 2.2, 2.3 | 3 | 4.1 | 4.2 | 4.3 | 5.1 | 5.2 | 8 | 9* |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 excl. 1.4S | 9.3.2.2.5 | X | X | X | X | X | X | X | X | X | X |
| 2.1 | X | — | — | — | — | — | — | — | — | — | X |
| 2.2, 2.3 | X | — | — | — | — | — | — | — | — | — | — |
| 3 | X | — | — | — | — | — | — | X | — | — | X |
| 4.1 | X | — | — | — | — | — | — | — | — | — | X |
| 4.2 | X | — | — | — | — | — | — | X | — | — | — |
| 4.3 | X | — | — | — | — | — | — | — | — | X | — |
| 5.1 | X | — | — | X | — | X | — | — | — | — | X |

| 8 | X | — | — | — | — | — | X | — | — | — | — |
| 9* | X | X | — | X | X | — | — | X | — | — | — |
X = Segregation required — must not be placed in the same package, overpack or ULD.
— = Same class / no special requirement.
* (Class 9) = see 9.3.2.1.3 for special conditions (lithium batteries, magnetized material, etc.).
Empty cell = No segregation required between those classes.
9.3.2.2 Separation of Explosive Substances and Articles
9.3.2.2.5 Packages of Division 1.4S (Compatibility Group S) may be loaded with all other classes of dangerous goods without segregation. For all other Division 1 items, segregation from every other class is mandatory ("X" in every column).
9.3.5 General Loading and Securing Requirements
- 9.3.5.1 Packages containing dangerous goods must be secured in the aircraft in a manner that prevents any movement during air transport that could change the orientation of the package or cause damage.
- 9.3.5.2 Operators must ensure that packages of dangerous goods are protected from damage during loading and transport.
9.3.6 Damaged Packages of Dangerous Goods
9.3.6.1 Packages of dangerous goods which appear to be damaged or leaking must not be loaded onto an aircraft.
9.3.6.2 If a package of dangerous goods is found to be damaged or leaking after it has been loaded, it must be removed or arrangements must be made for its removal by appropriately qualified personnel.
9.3.6.3 The aircraft position where the damaged package was stowed must be inspected for contamination and any hazardous residue must be removed.
State Variation: VEG-02
9.3.7 Replacement of Marks and Labels
If marks or labels on a package become unreadable during transport, they must be replaced using information from the Shipper's Declaration or the air waybill, in accordance with 2.6.7, 7.1.4.2, 7.1.5.3 and 7.1.5.5.
9.3.10 Loading of Carbon Dioxide, Solid (Dry Ice)
9.3.10.1 When dry ice (UN 1845) is used as a refrigerant for non-dangerous goods, or is carried as a dangerous good, the aircraft must have adequate ventilation to prevent dangerous concentrations of CO₂ in crew and passenger areas.
9.3.10.2 Packages containing dry ice must be marked with the net weight of dry ice and positioned to allow gas release in a manner that does not impinge on the aircraft structure.
9.3.10.3 Checked baggage containing dry ice must be tagged using a dry ice baggage tag (Figure 9.3.B) indicating the net weight. Packing Instruction 954 applies.
9.3.13 Loading of Live Animals with Dangerous Goods
- 9.3.13.1 Live animals should not be loaded in close proximity to cryogenic liquids or dry ice. CO₂ vapours are heavier than air and concentrate at lower levels — therefore live animals should be stowed above packages containing dry ice.
- 9.3.13.2 Category II-Yellow and Category III-Yellow radioactive packages must be separated from live animals by at least 0.5 m for journeys of 24 hours or less, and 1.0 m for journeys exceeding 24 hours.
Note: In certain circumstances dry ice may be packaged with live animals as a coolant (e.g. bees), provided all other dry ice requirements are met.
9.3.14 Loading of Wheelchairs and Battery-Powered Mobility Aids
9.3.14.1 Non-spillable / Nickel-Metal Hydride / Dry Batteries
Wheelchairs with non-spillable wet batteries (SP A67), NiMH batteries (SP A199) or dry batteries (SP A123), carried with operator approval as checked baggage, must be loaded per 2.3.2.2.
9.3.14.2 Spillable Batteries
Wheelchairs with spillable batteries, carried with operator approval as checked baggage, must be loaded per 2.3.2.3.
9.3.14.3 Lithium-Ion Batteries
Wheelchairs with lithium-ion batteries, carried with operator approval, must be loaded per 2.3.2.4.
9.3.14.4 Pilot-in-Command Notification
The pilot-in-command must be informed of: (a) the location of mobility aids with installed batteries; (b) the location of removed batteries; and (c) the location of spare batteries, either in the cargo compartment or (for lithium-ion) in the passenger cabin.
