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

• Segregation of packages containing DG and stowed
  in the 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

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

Prohibited Stowage area
3m 3m
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 24 m,
  including
• 
  intervening compartment
