For the purpose of stowage of dangerous goods IMDG Code divides the ships into two groups

  1.  cargo ships or passenger ships carrying a number of passengers limited to not more than 25 or to 1 passenger per 3 m of overall length, whichever is the greater number;
  2.  other passenger ships in which the limiting number of passengers transported is exceeded.

Passenger ships are categorized as

“passenger ships carrying a number of passengers limited to not more than 25 or to 1 passenger per 3 m of overall length, whichever is the greater number

Or

“Other passenger ships in which the limiting number of passengers transported is exceeded”

Individual dangerous goods are assigned with stowage categories A, B, C, D, or E in the Dangerous Goods List in IMDG Code and these are specifically assigned for On Deck, Under Deck or whether prohibited on passenger ships.

See stowage categories of IMDG Code here 

Stowage categories A to E are for goods other than Class 1 (Explosives).

For Class 1 explosives there is another set of stowage categories as shown in below images.

Section 7.1.7.5 of IMDG Code describes in full the conditions of stowage of explosives in passenger ships.

Below is quoted from IMDG Code
