The IMDG Code was designed for mariners

and first adopted by

the means of IMO resolution A.81 (IV) in 1965.

The provisions of the Code affect industries,

storage, warehousing, handling and

transport services from

manufacturers to consignees.

IMDG Code : Origin

- Classification and Terminology.

- Identification and Packaging,

- Marking, Labelling and Placarding.

- Documentation

of dangerous cargoes

for transport by sea.

IMDG Code : Scope


- Emergency Schedules for ships carrying dangerous goods ( EmS ).

- Medical First Aid Guide for use in accidents involving dangerous goods ( MFAG ).

- Code of safe practice for solid Bulk Cargoes ( BC Code ).

- Reporting procedures under SOLAS 74 and MARPOL 73/78.

- IMO / ILO guidelines for packaging cargo in freight containers or vehicles.

IMDG Code requires written statements

in the form of

declarations or certificates

that packages, freight containers

and/or vehicles are

properly packed.


Classification of Dangerous Goodsin Packaged FormsPacking & Packaging

Types of packages and packaging

are recommended by IMDG Code

to ensure a high degree of safety.

Specifications and performance tests

applicable are available in the annex 1.



Requirements for

intermediate bulk containers ( IBC's ):

- Rigid, semi-rigid or flexible portable packaging.

- Other than those specified in the annex 1.

Specifications and performance tests

applicable are available in section 26

of the General Introduction.



Requirements for portable tanks and road tank vehicles are given in section 13 of the General Introduction :

Type 1, 2 and 4 :

Liquids other than liquefied gases.

Type 5 and 6 :

Non-refrigerated liquefied gases.

Type 7 and 8 :

Refrigerated liquefied gases.



Other provisions given in the General

Introduction of the IMDG Code:

Section 12

Freight container traffic.

Section 17

Carriage on roll-on roll-of ships.

Section 19

Carriage in barges or barge-carrying

ship.



Dangerous goods must be identified according

to section 7 of the IMDG code for the necessary

care and precautions of those involved:

- Product name.

- UN number.

- Marine pollutant, if the case,

on documentation accompanying

a consignment of dangerous goods.


Classification of Dangerous Goodsin Packaged Forms: Identification,Marking, Labeling, Placarding

Each package should be durably marked :

- Product name.

- UN number.

- Marine pollutant, and If required by the

IMDG Code with the marine pollutant mark.

In case of cargo-transport units,

enlarged labels ( Placards ) should be used

and fixed to each cargo-transport.



Are harmful substances as defined in article 2 of the MARPOL 73/78

and its Annex III.

Marine pollutant : which have an extreme pollution potential are identified as severe maritime pollutants.Incidents involving the good must be reported.



The following segregation terms used are : - Away from... - Separated from... - Separated by a complete compartment or hold from... - Separated longitudinally by an intervening compartment or hold from...

Two substances or articles are considered mutually incompatible

when their storage together may result in undue hazards in cases

of leakage or spillage.

Dangerous GoodsSolid Bulk Materials

IMDG Code


1- Structural damage due to improper

distribution of the cargo.

2- Loss or reduction of stability due to

a shift of cargo or cargo liquefying.

3- Chemical reaction.

Hazards associated with the shipment of

solid bulk material come under the following

main categories :

Solid Bulk Materials : Hazards


- Appendix A

Bulk materials which may liquefy.

- Appendix B

Bulk materials possessing chemical hazards.

- Appendix C

Bulk materials which are neither liable to

liquefy nor to possess chemical hazards.

The Solid Bulk Carrier Code makes the following distinctions :

Carriage of grain is regulated under the International Code for the Safe Carriage of Grain.



High Density Cargoes

Danger of over-stressing is particularly relevant when the ship is moving at sea.

Require careful distribution within prescribed limits to prevent over-stressing.

In port, careful consideration must be given to the sequence of loading and the quantity of materials loaded at each port as well for the technique used for unloading.

Structure damage, unless discover in time,may result in the loss of the ship.



Cargoes Liable to Liquefy

Cargoes which may liquefy must be kept in a dry or nearly dry state.

Liquefaction of cargoes results in loss of the ship stability and possible loss of the ship.

Increase of moisture content above the transportable moisture limit may result of liquefaction.

The shipper should provide the information.

Sampling procedures are specified in the BC Code.



Cargoes Liable to Shift

Trimming instructions are specified for cargoes with an angle of response: - Less than or equal to 30°. - 30° to 35°. - Greater than 35° = Greater care.

The measure of the danger of shifting to which a non-cohesive cargo is subject is given in its angle of response.

BC Code makes a distinction between cohesive and non-cohesive cargoes.



Class 4.1 - Flammable solids.

Class 4.2 - Substances liable to spontaneous combustion.

Class 4.3 - Substances in contact with water emit flammable gases.

Class 5.1 - Oxidizing substances.

Are classified in the similar way to packaged dangerous goods:


Solid Bulk MaterialsSolid Bulk Materials : Hazards

Class 6.1 - Toxic ( poisonous ) substances.

Class 6.2 - Infectious substances.

Class 8 - Corrosives.

Class 9 - Miscellaneous dangerous substances and articles.

Class 7 - Radioactive materials.

MHB - Materials Hazardous only in Bulk.


Solid Bulk MaterialsSolid Bulk Materials : Hazards

Stowage and segregation requirements apply

similarly to packaged dangerous goods

between:

- Bulk materials and bulk materials.

- Bulk materials and packaged form.


Solid Bulk Materials posing Chemical Hazards


Dust is inherent to cargo operations with many bulk materials.

Dust should be reduced to the minimum.

Precautions are necessary to minimize the risks due to exposure to the residual dust of certain materials carrier in bulk.

High standard of personal is required with use of protective clothing and barrier creams particularly in case of toxic materials.


Solid Bulk Materials posing Dust Hazards


Dust created by certain cargoes may constitute

an explosion hazard especially during :

- Cargo operations.

- Cleaning holds.

The risk can be minimized by :

- Ventilating spaces with dust-laden atmospheres.

- Hosing down rather than seeping.

Sampling and laboratory test procedures are

specified in the BC Code.


Solid Bulk Materials posing Dust Hazards


To assess the dangers for those on board, a shipmaster must be provide with the information essential to load and unload the ship safely.

The shipper should provide the shipmaster with appropriate certificates of test with details as : - chemical hazards. - flow moisture point. - stowage factor. - moisture content. - angle of response, etc…
