Handling, Loading, Stowage and Segregation
Handling
Dangerous goods must be handled so that packages are not dropped, dragged or exposed to conditions that could damage them. Packages must be inspected for damage before loading; a damaged package must not be loaded and must be reported.
Loading and stowage
Stowage must protect packages from other cargo and from heat sources. Packages labelled Cargo Aircraft Only must be loaded only on cargo aircraft. Packages must be secured to prevent movement in flight. Liquids must be stowed upright where orientation labels are present.
Segregation
Segregation rules prevent incompatible goods from being stowed together. The key concept is that segregation is based on the hazard labels, not on the shipper's preferences. Certain classes must be separated by a specified distance or by a physical barrier. A common trap is assuming that segregation only applies between dangerous goods; it can also apply between dangerous goods and other cargo such as foodstuffs.
Worked example
A package of Class 3 flammable liquid is to be loaded next to a package of Class 5.1 oxidizer. The segregation table requires separation. The answer: the packages must not be stowed adjacent; they need the required separation or a barrier as specified in the segregation rules.
Rule of thumb
Before loading, check the labels for segregation, confirm the aircraft type matches the quantity limits, and secure every package. If a package is damaged or the segregation cannot be met, do not load it.
