1. What Are Dangerous Goods?

According to IATA DGR, dangerous goods (also known as hazardous materials or DG) are articles or substances which, when transported by air, are capable of posing a significant risk to health, safety, property, or the environment. These materials require specific handling, packaging, documentation, and training to ensure safe transport.

Examples of common dangerous goods shipped by air include: lithium batteries (in electronics), paints and adhesives (flammable liquids), medical oxygen cylinders (gases), dry ice (used as refrigerant), perfumes and aerosols, and industrial chemicals. Understanding classification is the first step toward compliance.

2. Regulatory Framework – ICAO & IATA

Two primary documents govern dangerous goods by air:

• ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air: The international baseline standard adopted by all ICAO member states. Legally binding under the Chicago Convention.
• IATA Dangerous Goods Regulations (DGR): Incorporates ICAO Technical Instructions with additional, stricter airline-specific requirements. The practical guide used by shippers, forwarders, and carriers worldwide. Updated annually.

Additionally, national aviation authorities (FAA in US, EASA in Europe, DGCA in India) enforce these regulations and may impose additional restrictions. Operators must also comply with their own Operations Specifications (OpSpecs) approved by their national authority.

3. The 9 Classes of Dangerous Goods

IATA DGR divides dangerous goods into 9 hazard classes. Each class has distinct risks and handling requirements:

Important note: Many substances have multiple hazards and are assigned a primary and subsidiary hazard class. Lithium batteries (Class 9) are currently the most scrutinized DG category due to fire risk.

4. Packaging Requirements & UN Specifications

Dangerous goods must be packaged in UN-certified packaging that has passed rigorous performance tests. According to IATA DGR Section 6, packaging must:

• Bear UN specification markings (e.g., "1A1/Y1.4/150/22/USA/M1234")
• Be compatible with the hazardous material (no chemical reaction)
• Meet performance standards for stacking, vibration, drop, and pressure tests
• Include appropriate inner packaging and absorbent/ cushioning material
• Be closed according to manufacturer specifications

5. Marking, Labeling & Documentation

Every dangerous goods shipment requires three layers of communication:

Marking (On the Package)

• UN number (e.g., UN3480 for lithium ion batteries)
• Proper shipping name (e.g., "Lithium ion batteries")
• Shipper and consignee name/address
• Net quantity per package
• "Overpack" marking if applicable

Labeling (Hazard Communication)

• Primary hazard label (diamond, 100x100mm, color-coded by class)
• Subsidiary hazard label (if applicable)
• Cargo Aircraft Only label (for items forbidden on passenger aircraft)
• Lithium battery handling label (for cells/batteries)

Documentation

• Shipper's Declaration for Dangerous Goods (DGD): IATA form certifying the shipment complies with regulations. Must be signed by trained personnel.
• Air Waybill (AWB): Includes "Dangerous Goods" notation and indicates if shipment is "Cargo Aircraft Only"
• Packing List: Detailed contents with DG information

6. Lithium Batteries – Special Restrictions

Lithium batteries (rechargeable ion and non-rechargeable metal) are classified as Class 9 dangerous goods and subject to the strictest current regulations due to thermal runaway fire risk:

7. Training Requirements for Shippers & Handlers

IATA DGR Section 1.5 mandates dangerous goods training for all personnel involved in preparing, offering, accepting, or handling dangerous goods shipments. Key requirements:

• Initial training: Complete before performing any DG function
• Recurrent training: Every 24 months minimum (many organizations require annually)
• Training must be function-specific: Shippers, packers, loaders, acceptance staff all have distinct requirements
• Documentation: Training records must be retained (typically 36 months after employment)
• Certification: IATA DGR certificate issued upon completion (valid 24 months)
