FLAMMABLE EXPLOSIVE MATERIAL
CLASS 1: EXPLOSIVES
They should be stowed away from the crew quarters and the ship's hull, just under the hatch covers. Examples of substances included in this class: Black Powder, Cartridges, Smoke Bombs, Ammunition, Dynamite, etc.
CLASS 2: GASES
. CLASS 2.1 FLAMMABLE GAS: They should be stowed away from all heat sources and crew quarters. Examples of substances included in this class: Acetylene, Ethane, Ethylene, Methane, Hydrogen, Lighter Gas, etc.
. CLASS 2.2 TOXIC GAS: They should be stowed away from all heat sources, crew quarters, and foodstuffs. Examples of substances included in this class: Ammonia, Fluorine, Prussic Acid, Chloride, Carbon Monoxide, etc.
. CLASS 2.3 NON-FLAMMABLE COMPRESSED GAS: Should be stored in cool, well-ventilated areas on or below deck. Cylinders filled with these gases expand when heated, which is very dangerous because it causes explosions. Examples of substances included in this class: Argon, Helium, Carbon Dioxide, Coal Gas, Oxygen, etc.
CLASS 3: FLAMMABLE LIQUID
Flammable liquids are divided into 3 groups according to the flash point of the vaporized gas when heated.
. CLASS 3.1 GASOLINE: Flash point is lower than 180 C. It should always be stacked on the deck.
. CLASS 3.2 FUEL OIL: Flash point is between 180 C and 230 C. It should be stacked on the deck or below deck.
. CLASS 3.3 FUEL OIL: The burning point is between 230C and 610C. It should be stacked under the deck.
CLASS 4: SOLIDS (SOLID)
. CLASS 4.1 FLAMMABLE SOLID: They should be stacked on the deck or under the deck. They should be kept away from living spaces. Examples of materials included in this class: Aluminum Powder, Celluloid, Naphthalene, Red Phosphorus, Films, Turpentine, Dry Fibers, etc.
CLASS 4.2 SPONTENOUSLY COMBUSTIBLE: They should be stacked in very well ventilated areas, and the stacking intervals should be created in a way that provides air circulation. Examples of materials included in this class: Copra, Fish Meal, Dry Grass, Charcoal, etc.
. CLASS 4.3 DANGEROUS WHEN WET: Solids that exhibit flammability when in contact with water or when wet. They should be stored in well-ventilated, dry areas and contact with water should be avoided at all costs.
Substances included in this class: Alkaline alloys, Barium, Carbide, Ferro Silicon, Sodium, Magnesium, etc.
CLASS 5: OXIDIZING SUBSTANCES
. CLASS 5.1 OXIDIZING AGENT: Substances included in this class create an environment that facilitates combustion by releasing oxygen. Due to these properties, they should not be stacked next to flammable substances. Examples of substances included in this class: Nitrate, Artificial Fertilizer, Ammonium Sulfate, Barium Chlorate, etc.
. CLASS 5.2 ORGANIC PEROXIDES: Substances in this class can be flammable and explosive. They should be placed in dry and cool places, covered on the deck. Example substances included in this class: All peroxides are included in this class.
CLASS 6: TOXIC
. CLASS 6.1 TOXIC: Toxic substances can enter the human body through the mouth and can kill people. Therefore, they should be stacked away from food, beverages, living spaces and moisture-producing substances such as tobacco. Substances included in this class: Arsenic, Aniline, Barium Oxide, Phenol, Nicotine, Lead, Cyanide, Mercury products, etc.
. CLASS 6.2 MICROBIAL SUBSTANCES: These substances cause diseases because they contain microbes. They should be stacked away from food, drink and living spaces. In cases of danger, the nearest health authority should be notified. Substances included in this class: Bone, Bone Oil, Compressed Meat Waste, Animal Skins, Blood Powder, etc.
CLASS 7 : RADIOACTIVE SUBSTANCES
These substances are transported in special containers. The containers must be absolutely undamaged. They should be stacked preferably on the deck, away from personnel quarters, foodstuffs, undeveloped films, medicines and chemical substances.
