Which type of transport prohibits certain dangerous goods on passenger aircraft?

• A. Passenger aircraft/Combined passenger-cargo restrictions under IATA DGR; many items are restricted or prohibited.
• B. All air shipments are allowed.
• C. Only government shipments face restrictions.
• D. Hazmat can be shipped on passenger aircraft with no labeling.

Answer: (B)

Passenger aircraft have strict dangerous goods controls because safety in the cabin and hold is a priority. Under the IATA Dangerous Goods Regulations, many hazardous items are prohibited on passenger planes, and others are allowed only under tightly limited conditions with specific packaging, labeling, documentation, and quantity limits. This is why the type of transport described as passenger aircraft shipments carries prohibitions and restrictions for dangerous goods, whereas cargo-only operations have different rules and can carry more hazards under different requirements. The other options aren’t accurate because some shipments are restricted or prohibited, not all air shipments are allowed, government shipments aren’t the sole restricted category, and hazmat cannot be shipped on passenger aircraft without proper labeling and compliance.
