IATA DGR (Air) flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Hidden dangerous goods

Items whose contents may include dangerous goods not apparent from their description, such as lithium batteries, aerosols, fuels, magnets or dry ice. They must be identified and declared before carriage.

Shipper responsibility

The shipper classifies, packs, marks, labels and documents the shipment and signs the declaration. Primary responsibility for compliance with the DGR rests with the shipper, not the operator.

Operator responsibility

The operator verifies that shipments meet acceptance requirements, provides trained staff, and ensures loading and handling comply with the DGR and any more restrictive State requirements.

DGR effective period

The IATA Dangerous Goods Regulations are issued annually and apply for the calendar year stated on the cover. The ICAO Technical Instructions are the underlying international standard adopted by States.

Passenger and crew provisions

DGR 2.3 lists the dangerous goods passengers and crew may carry, such as limited batteries and aerosols, and the conditions for each. Items not listed are forbidden.

Dangerous goods approval

An operator must hold an approval or exemption from the appropriate authority to carry dangerous goods. The approval defines which classes and quantities may be carried.

Recurrent training requirement

Personnel involved in preparing or accepting dangerous goods must be trained and recurrently retrained. Training records must be retained and produced to the authority on request.

Nine hazard classes

Class 1 explosives, 2 gases, 3 flammable liquids, 4 flammable solids, 5 oxidizers and organic peroxides, 6 toxic and infectious substances, 7 radioactive, 8 corrosives, 9 miscellaneous.

Packing group meaning

PG I indicates great danger, PG II medium danger and PG III minor danger. Packing groups are assigned to classes 3, 4, 5, 6.1, 8 and some class 9 entries.

Cargo aircraft only

Some entries are forbidden on passenger aircraft but permitted on cargo aircraft. These shipments require the Cargo Aircraft Only label and must not be loaded on passenger aircraft.

Limited quantity shipment

A shipment prepared under a Y packing instruction, limited to the maximum net quantity per package shown in the DGR. The limited quantity mark replaces the hazard label.

Excepted quantity code

Excepted quantities use codes E1 to E5, each setting maximum net quantities per inner and outer packaging. The excepted quantity mark is required and hazard labels are not.

UN specification packaging

Packaging tested and marked to UN standards. The packing instruction in Column 8 of the Dangerous Goods List specifies which UN packagings are permitted for an entry.

Radioactive transport index

The transport index is the maximum radiation dose rate at one metre from the package surface, expressed in millisieverts per hour. It governs package category and loading separation.

Subsidiary risk

An additional hazard of a substance beyond its primary class, shown in the Dangerous Goods List. A subsidiary risk label is applied in addition to the primary hazard label.

Proper shipping name

The name shown in the Dangerous Goods List for an entry. For n.o.s. entries a technical name in parentheses is added where the DGR requires it.

UN packaging mark

The mark on UN specification packaging shows the UN symbol, packaging code, packing group, maximum gross mass and year of manufacture, allowing verification against the packing instruction.

Orientation label

A label showing two arrows pointing upward, applied to combination packagings containing liquids to indicate the required upright orientation during handling and loading.

Lithium battery mark

A mark required for lithium cells and batteries shipped under Section II of the applicable packing instruction. It identifies the shipment and the battery type.

Overpack marking

When packages are placed in an overpack, the overpack must be marked with the word Overpack and must display the required marks and labels of the packages inside.

Technical name requirement

For entries in the n.o.s. family, the proper shipping name must be supplemented by the technical name of the substance in parentheses, as required by the DGR list.

Hazard label selection

The primary hazard label matches the class or division. Subsidiary risk labels are added where the Dangerous Goods List shows a subsidiary risk for that entry.

Shipper's declaration

The document signed by the shipper stating the UN number, proper shipping name, class, packing group, quantity, packing instruction and the departure and destination airports.

Declaration signature

The shipper's declaration must be signed by the shipper. The signed declaration must not be altered; a corrected declaration must be re-signed before acceptance.

Acceptance check scope

The operator compares the declaration with the package: UN number, proper shipping name, class, packing group, quantity, packing instruction, marks and labels must all match.

Package condition check

The acceptance check verifies the package is undamaged, correctly marked and labelled, and does not contain forbidden dangerous goods before the shipment is accepted for carriage.

Acceptance record retention

The operator records each dangerous goods acceptance check and retains the record for the period required by the operator and the State, producing it on request.

Air waybill entries

The air waybill must show the number of packages and the nature of the dangerous goods. It accompanies the shipper's declaration for the shipment.

Refusal of shipment

The operator must refuse a shipment whose declaration or package does not comply with the DGR. The shipment may be returned to the shipper for correction.

Segregation of incompatible goods

Incompatible dangerous goods must be separated during loading and storage according to the DGR segregation table, so that a leak or fire in one does not affect the other.

Pilot-in-command notification

Before flight the pilot-in-command must be informed of the dangerous goods on board, including their location, so that emergency response guidance can be applied.

Dangerous goods incident reporting

The operator must report dangerous goods incidents and accidents to the appropriate authority and must maintain an emergency response plan for handling them.
