General Stowage Precautions
General stowage precautions for goods of class 2 is addressed in chapter 7 section 126.96.36.199 of IMDG Code. Requirement also addresses section 188.8.131.52.2. for gases loaded in containers which may cause oxygen depleted or enriched atmosphere inside containers.
Specific Stowage Requirements
Specific stowage requirement of each dangerous goods is listed in Column 16 of Dangerous Goods List in Chapter 3.2 of IMDG CodE.
Class 2.2 may be allowed on deck or under deck or may only be allowed on deck in specific cases
Example 1 : 1002 AIR, COMPRESSED Class 2.2 – Stowage Category A. ( ON DECK OR UNDER DECK )
Example 2 : 1963 HELIUM, REFRIGERATED LIQUID Class 2.2 – Stowage Category D. ( ON DECK ONLY )
From above examples we understand that certain class 2.2 is allowed on or under deck but certain class 2.2 is allowed only on deck.
Hence it is imperative that we must look at stowage category for each dangerous goods to ascertain the particular stowage requirement.
