Slide 2 · DG SEGREGATION
DG SEGREGATION
IMDG CODE CHAPTER 7.2
Dangerous goods must be stowed according to the required segregation categories.
1
AWAY FROM
Minimum segregation requirement as defined in IMDG Code 7.2. Arrangement depends on vessel design, cargo unit type and stowage location.
2
SEPARATED FROM
In different compartments or holds. A fire-resistant deck or bulkhead is sufficient.

SEPARATED BY A COMPLETE COMPARTMENT OR HOLD FROM
A complete intervening compartment or hold separates the two dangerous goods.
4
SEPARATED LONGITUDINALLY BY AN INTERVENING COMPLETE COMPARTMENT OR HOLD FROM
At least one complete compartment or hold must be between the two dangerous goods longitudinally.
Improper segregation can turn a cargo incident into a major emergency.
