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

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
.the safety of other cargo in one hold

International Maritime Dangerous Goods Code
First Int. Convention: after Titanic in 1914
First edition of SOLAS (not E.F. due to first world war)
In this version the same concept in 1894 ,
-the definition of which cargo is DG left to
Contracting Government
also to take precautionary measures for
Packing, mode of transport, Stowage, and
segregation. permission
As a result many different regulations and
practices adopted by each country

International Maritime Dangerous Goods Code
Second version of SOLAS in 1929
In article 24 related to DG same concept of
SOLAS 1914 (not E.F due to 2 nd world war)
These regulations applied only for ships and
not other modes of transport and also the traffic
of DG increased
Third version of SOLAS in 1948
New ch. 6 added, deals with carriage of grain
and DG (during the conference they understand that this ch. Is not adequate

Other decisions:
1) DG BASED ON THEIR PROPERTIES AND
CHARACTERISTICS
2) A LABELLING SYSTEM
ALSO UNIFORM REGULATIONS TO BE DEVELOPED

accordance with the degree of danger they present:
Packing group 1: subs. presenting high danger
Packing group 2: subs. presenting medium
danger
Packing group 3: subs. presenting low danger

conventional way
Legend :
.1) reference package………………………..
.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

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
ports and shipping organization
30
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.
ports and shipping organization
31
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
24 m, including
intervening compartment
