3.5.1 Special requirement for segregation and stowage of CTUs on partially weathertight hatchway covers without effective gutterbars

 Where "not in the same vertical line unless separated by a deck" is required in the IMDG Code, the following applies:

  • .1 when the reference CTU is stowed on deck in positions specified by "A" in figures 3.2.3-1 and 3.2.3-2, CTUs containing incompatible dangerous goods should not be stowed within the relevant sensitive vertical lines under deck. Examples are illustrated in figures 3.5.1-1 and 3.5.1-2; and

  • .2 when the reference CTU is stowed under deck in positions as specified by "C" in figures 3.2.3-1 and 3.2.3-2, CTUs containing incompatible dangerous goods should not be stowed on the hatches above the hold. Example is illustrated in figure 3.5.1-3.

Figure 3.5.1-1 Example of segregation within sensitive vertical lines (reference CTU is above left hatchway cover)

Figure 3.5.1-2 Example of segregation within sensitive vertical lines (reference CTU is above centre hatchway covers)

Figure 3.5.1-3 Example of segregation within sensitive vertical lines (reference CTU is in sensitive vertical line under deck)
