Segregation (Dangerous Goods)
Segregation is keeping apart dangerous goods that could react hazardously if they leaked or burned together. The IMDG Code uses a segregation table with levels such as away from, separated from, separated by a complete compartment or hold from, and separated longitudinally by an intervening complete compartment or hold from. The rules apply inside a single container and between container positions on the ship. Planners check them in the stowage plan, and shippers must avoid forbidden combinations when packing a box.
