Dangerous Goods Air Transport & IATA Regulations: Essential Safety Requirements
Dangerous goods air transport is an essential but high-risk component of the global supply chain. The International Air Transport Association (IATA) Dangerous Goods Regulations (DGR) provide the global standard for airlines and freight forwarders handling dangerous goods transportation. This article provides a comprehensive analysis of the basic requirements for dangerous goods air transport, the core content of IATA regulations, and how to ensure compliance.
Key Focus Areas
What Are Dangerous Goods?
According to IATA regulations, dangerous goods are articles or substances that are capable of posing a risk to health, safety, property, or the environment. These items may present risks during air transportation due to their nature, condition, or quantity. Dangerous goods air transport requires strict adherence to specific safety standards and operational procedures.
IATA Dangerous Goods Classification System
The IATA Dangerous Goods Regulations classify dangerous goods into 9 classes, which form the foundation of dangerous goods air transport knowledge:
Class 1 – Explosives
Such as gunpowder, fireworks, signal flares
Class 2 – Gases
Including flammable, non-flammable non-toxic, and toxic gases
Class 3 – Flammable Liquids
Such as gasoline, alcohol, paint
Class 4 – Flammable Solids
Such as sulfur, matches, metal powders
Class 5 – Oxidizing Substances
Such as peroxides, chlorates
Class 6 – Toxic Substances
Including toxic and infectious substances
Class 7 – Radioactive Material
Radioactive materials used in medical and industrial applications
Class 8 – Corrosives
Such as acids, alkalis, battery fluid
Class 9 – Miscellaneous Dangerous Goods
Other hazardous items not covered by the first 8 classes
Core Requirements of IATA Dangerous Goods Regulations (DGR)
1. Personnel Training and Certification
All personnel involved in dangerous goods transportation must receive IATA-certified training and undergo recurrent training every two years based on their responsibilities. Training content includes:
- Dangerous goods classification and identification
- Dangerous goods packaging requirements
- Marking and labeling specifications
- Documentation preparation and dangerous goods declaration
- Emergency procedures and safety measures
2. Packaging Specifications and Standards
Dangerous goods air transport must use UN-certified packaging, and the packaging must:
- Be suitable for the nature and hazard of the contents
- Withstand the pressures of normal transport conditions
- Prevent leakage of contents or reaction with the external environment
- Comply with specified capacity and weight limitations
3. Marking and Labeling Requirements
All dangerous goods packages must be correctly marked and labeled, which is a critical element of air cargo safety:
- Proper shipping name and UN number
- Appropriate hazard class labels and subsidiary risk labels
- Handling labels (such as orientation arrows, packaging instructions)
- Complete shipper and consignee information
4. Documentation and Declaration Requirements
Dangerous goods transportation must be accompanied by a Shipper’s Dangerous Goods Declaration, containing:
- Detailed shipper and consignee information
- Proper shipping name and UN number of the dangerous goods
- Class and subsidiary risk identification
- Packing group and quantity information
- Packaging type and specifications
- 24-hour emergency contact information
5. Quantity Limitations and Segregation Requirements
IATA regulations specify quantity limitations for different classes of dangerous goods, as well as segregation requirements between incompatible dangerous goods to prevent dangerous reactions during transportation.
Dangerous Goods Prohibited from Air Transport
Certain dangerous goods are forbidden from air transportation under any circumstances, including:
- Substances that can easily explode or undergo dangerous reactions under normal transport conditions
- Certain high-risk infectious substances
- Certain radioactive materials and devices
- New chemical substances that have not been tested and approved
- Items that do not comply with IATA Dangerous Goods Regulations packaging requirements
Emergency Procedures and Safety Measures
IATA regulations require all relevant parties to develop and be familiar with emergency procedures for dangerous goods incidents, including:
- Leak detection and handling procedures
- Fire prevention and response measures
- Personnel first aid and evacuation procedures
- Incident reporting and notification requirements
- Professional cleanup and follow-up processes
Conclusion
Compliance with IATA Dangerous Goods Regulations is not only a legal requirement but also essential for ensuring air cargo safety. Dangerous goods air transport involves multiple responsibilities, and shippers, freight forwarders, and airlines must work together to ensure every aspect of dangerous goods transportation complies with IATA regulations, thereby protecting personnel, equipment, and the environment.
For any uncertain items, it is recommended to consult professional dangerous goods advisors or contact airlines directly for guidance. Proper dangerous goods classification, appropriate dangerous goods packaging, and complete dangerous goods declaration are fundamental to successful dangerous goods air transport.
