1. International Maritime Dangerous Goods Code
History of IMDG Code
-Nowadays more than 50 % of Goods are DANGROUS
Hazardous or harmful to the environment . The cargoes includes products transported in bulk, such as: solid or liquid chemicals, gases and products for and of the oil refinery.
Some of them dangerous from safety point of view, and others hazardous when carried in bulk and some harmful to the Marine Environment
20% of these cargoes transported in package form including
-shipborne barges on LASH, freight containers, bulk packagings, portable tanks, tank containers, road tankers, IBCs, trailers, swap bodies, and other transport units
History of IMDG Code
-Nowadays more than 50 % of Goods are DANGROUS
-What is DG: Harmful to the Environment & safety or just to the Environment

2. International Maritime Dangerous Goods Code
First regulation: in 1894 in England
No ships could sail if carries any explosive or hazardous materials due to its nature and quantity or mode of stowage may cause danger the health or lives of the passenger or the safety of the ship

Legend :

.2) package containing incompatible goods
.3) deck resistant to fire and liquid …………
Note: full vertical lines represent transverse bulkheads btw cargo spaces resistant to fire and liquid
Away from: effectively segregated so that the incompatible goods cannot interact dangerously in the event of an accident but may be transported in the same compartment or hold or on deck, provided a minimum horizontal separation of 3 meters is obtained

30. International Maritime Dangerous Goods Code
Away from separated from
Separated from: in different compartments or holds when stowed under deck. Provided the intervening deck is resistant to fire and liquid, a vertical separation, i,e, in different compartments, may be accepted as equivalent to this segregation for on deck stowage, this segregation means a separation by a distance of at least 6 meters horizontally

31. International Maritime Dangerous Goods Code
Separated by a complete compartment or hold from
Either a vertical or a horizontal separation, if the intervening decks are not resistant to fire and liquid, then only a longitudinal separation, I.e. by an intervening complete compartment or hold, is acceptable. For on deck stowage, this segregation means a separation by a distance of at least 12 meters horizontally. The same distance has to be applied if one package is stowed on deck and the other one in an upper compartment.
Separated by a complete compartment or hold from
Either a vertical or a horizontal separation, if the intervening decks are not resistant to fire and liquid, then only a longitudinal separation, I.e. by an intervening complete compartment or hold, is acceptable. For on deck stowage, this segregation means a separation by a distance of at least 12 meters horizontally. The same distance has to be applied if one package is stowed on deck and the other one in an upper compartment.

32. International Maritime Dangerous Goods Code
Separated longitudinally by an intervening complete compartment or hold from:
Vertical separation alone does not meet this requirement. Between a package under deck and one on deck, a minimum distance of 24 meters, including a complete compartment, must be maintained longitudinally. For on deck stowage, this segregation means a separation by a distance of at least 24 meters longitudinally m, including
