Should be stored away from the crew’s quarters and the ship’s boats and immediately under the hold’s hatches

Should be stored away from crew’s quarters and any source of heat.

Should be stored away from any source of heat, the crew’s quarters and foodstuffs.

Store on or under the deck in a cool, well-ventilated place. Containers filled with this kind of gas will expand if heated and there is a high risk of an explosion.

Combustion at less than 18ºC. Should always be stored above the deck.

Combustion at between 18ºC and 23ºC. Should be stored above or below the deck.

Combustion at between 23ºC and 61ºC. Should be stored below the deck.

Should be stored on top or below the deck. Should be kept away from living quarters.

Should be stored in well ventilated areas and air should be able to circulate between the stored materials.

Solids which are inflammable when wet or when in contact with water. Should be stored in well ventilated, dry areas and always away from any contact with water.

The substances in this category can create an inflammable environment when brought into contact with oxygen. For this reason they should not be stored next to combustible materials.

The substances in this class can be inflammable or explosive. They should be stored above deck, covered and in a dry, cool areas.

Toxic substances are those which can enter the human body through the mouth and cause death. For this reasons they should be stored away from foodstuffs, drinks, living quarters and materials which increase humidity, such as tobacco.

These substances contain microbes which can cause illness. They should be stored away from foodstuffs, drinks and living quarters. In case of danger the nearest health authority should be notified.

Radioactive Materials - These materials should be transported in specially sealed containers. The seals must always be completely undamaged. They should preferably be stored above deck and away from living quarters, foodstuffs, unprocessed films, pharmaceuticals and chemical substances. They are divided into three groups according to their level of radioactivity.

The substances in this class are solids or liquids possessing, in their original state, the common property of being able, more or less severely to damage living tissue. The escape of such a substance from its packaging may also cause damage to other cargo or the ship.

Substances and articles not covered by other classes which experience has shown, or may show, to be of such a dangerous character that the provisions of SOLAS should apply. These include substances that are transported or offered for transport at temperatures equal to or exceeding 1000 C and in a liquid state, and solids that are transported at temperatures equal or exceeding 2400 C;

MHB (materials hazardous only in bulk) cargoes are materials which possess chemical hazards when transported in bulk that do not meet the criteria for inclusion in the IMDG classes. They are Combustible solids, Self-heating solids, Solids that evolve into flammable gas when wet, Solids that evolve toxic gas when wet, Toxic solids, Corrosive solids. See also IMSBC code.
