Dangerous Goods Handling

Key Definitions and Terminology

• Dangerous Goods: Articles or substances that could endanger health, safety, property, or the environment during air transport.
• Dangerous Goods Accident: An event causing injury, property damage, or environmental harm due to dangerous goods.
• Dangerous Goods Incident: Any occurrence (other than an accident) related to dangerous goods that jeopardizes safety.
• Exemption: Official permission to carry certain dangerous goods under specified conditions.
• Incompatible: Dangerous goods that must not be packed or loaded together due to chemical or physical reactions.
• Packaging: Approved containers or materials used to safely enclose dangerous goods.
• UN Number: A unique four-digit code identifying each type of dangerous good.

Compatibility and Segregation Principles

Dangerous goods are grouped into categories based on their hazards. Some must be segregated to prevent dangerous reactions—flammables and oxidizers, for example, must not be stored together. Operators use detailed compatibility charts and checklists to ensure correct segregation during packing and loading.

Acceptance and Handling Requirements

• Only operators with specific approval may transport dangerous goods (except for certain exemptions).
• Every shipment must be accompanied by a correctly completed dangerous goods transport document and pass an acceptance checklist.
• The operator must provide the pilot-in-command with written information about all dangerous goods on board, including their location and quantity.
• Ground staff must retain copies of documentation for a set period after the flight.
• All personnel involved must be trained and records kept for at least three years.

Reporting Misdeclared or Undeclared Dangerous Goods

If dangerous goods are found undeclared or misdeclared in baggage or cargo, the operator must immediately report the discovery to the competent authority and the authority where the event occurred. This ensures prompt investigation and corrective action.

Cargo Aircraft Only Designation

Some dangerous goods are too hazardous for carriage on passenger aircraft and may only be transported on cargo aircraft. This restriction is based on the risk level and the ability to manage emergencies without endangering passengers.

Information for Passengers and Crew

Operators must inform passengers about prohibited dangerous goods before check-in and display notices at acceptance points. Crew and ground staff must be able to identify, handle, and respond to dangerous goods incidents according to the technical instructions.
