DG under the HVRsGoods of an inflammable,explosive or

dangerous nature, if not properlymarked or if shipped without the

knowledge and consent of the carriermay be landed, destroyed, jettisoned or

rendered innocuous at any time beforedischarge.



23

Such goods may be dealt in the sameway even if they are loaded with the

37

IMDG codeUniform, global rules for the safe transport bysea of dangerous goods and marine

pollutants in packaged form are nowcompulsory, following the entry into force on1 January 2004 of the 2002 amendments tothe International Convention for the Safety of

Life at Sea (SOLAS), 1974, making theInternational Maritime Dangerous Goods(IMDG) Code mandatory.



38

IMDG codeThe IMDG Code was developed as auniform international code for the

transport of dangerous goods by seacovering such matters as packing,marking, libeling and stowage of

dangerous goods with particularreference to the segregation ofincompatible substances.



39

IMDG codeThe IMDG Code lays down basic principlesand contains detailed recommendations for

individual substances, materials and articles,as well as a number of recommendations forgood operational practice including advice onterminology, packing, labelling, stowage,

segregation and handling, and emergencyresponse action.

Completely gas at 20 ° c at pressure of101.3kPa



60

Class 3 flammable liquids:Flash point:lowest temperature of aliquid at which its vapour forms an

ignitable mixture with air. A flammable liquid can not be ignited solong as its temperature remains below

the flash point.



62



63

Determination of flash point:Specified quantity of liquid in areceptacle, well below flash point.

Heat up slowly and periodically bring aflame near to the liquid surfaceThe lowest temperature you observe a

flash is the flash point temperature



64



65

Two types of flash point:Closed-cupOpen-cupOpen-cup few degrees higher.Closed-cup is recommended to be used.



66

Class 4 flammable solids:Class 4.1 flammable solidsDuring transport readily combustiblethrough friction, or exothermic reaction.Powdered, granular,pasty substancesaccording to the time and rate ofburning as per UN manual of tests andcriteria.

such as acids.If the SADT is less than 55 ° c it issubject to temperature control during

transport. ( Self Accelerating Decomposition Temperature )
