Flammable & Explosive Substance

CLASS 1:  EXPLOSIVES 

Stacking on the ship should be done away from the personnel area and the ship's hull, just below the hatch covers. Example substances included in this class: Black Powder, Cartridge, Smoke Grenade, Ammo, Dynamite etc.

CLASS 2:  GASES 

. CLASS 2.1   FLAMMABLE GAS: They should be stacked away from any heat source and personnel area. Example substances included in this class: Acetylene, Ethane, Ethylene, Methane, Hydrogen, Lighter Gas etc.

. CLASS 2.2   TOXIC GAS: They should be stacked away from any heat sources, personnel area and food items. Example substances included in this class: Ammonia, Fluorine, Prussic Acid, Chlorite, Carbon monoxide etc.

. CLASS 2.3   NON-FLAMMABLE COMPRESSED GAS: They should be stored in cool, well-ventilated areas on deck or under deck. Tubes filled with these gases expand when heated, which can cause explosions and are very dangerous. Example substances included in this class: Argon, Helium, Carbon Dioxide, Air Gas, Oxygen etc.

CLASS 3 : FLAMMABLE LIQUID 

Flammable liquids are divided into 3 groups according to the burning point of the vaporized gas when they are heated.

. CLASS 3.1 GASOLINE: Its burning point is lower than 180°C. It should always be stacked on the deck.

. SINIF 3.2 FUEL: Burning point is between 180 C and 230 C. They should be stacked on or under deck.

. CLASS 3.3 FUEL: Burning point is between 230 C and 610 C. It should  be stacked under the deck.

CLASS 4:  SOLID 

. CLASS 4.1  FLAMMABLE SOLID: They should be stacked on deck or under deck. They should be kept away from accommodations. Example substances included in this class: Aluminum Powder, Celluloid, Naphthalene, Red Phosphorus, Films, Naphtha Oil, Dry Fibers etc.

 CLASS 4.2  SPONTENOUSLY COMBUSTIBLE SOLID: They should be stacked in very well ventilated areas, and the stack spaces should be suitable for air circulation. Example substances included in this class: Copra, Fish Meal, Dry Grass, Charcoal etc.

. SINIF 4.3  DANGEROUS WHEN WET: Solids that burn when gets in contact with water or when wet. It should be stacked in well-ventilated dry places and contact with water should be absolutely avoided. 

Substances in this class: Alkaline alloys, Barium, Carbide, Ferro Silicon, Natrium, Magnesium etc.

CLASS 5: OXIDIZING SUBSTANCES 

. CLASS 5.1 OXIDIZING AGENTS: OXIDIZING AGENT: Substances in this class create an environment that facilitates combustion by releasing oxygen. Due to these features, they should not be stacked near flammable materials. Example substances included in this class: Nitrate, Fertilizer, Ammonium Sulphate, Barium Chlorate etc.

. CLASS 5.2   ORGANIC PEROXIDES: Substances in this class can be flammable as well as explosive. They should be placed in dry and cool places, covered on the deck. Substances in this class :All peroxides are included in this class.

CLASS 6: TOXIC 

. CLASS 6.1    TOXIC SUBSTANCES: Toxic substances can enter the human body orally and cause death. For this reason, they should be stacked away from food, beverages, accommodations, and moisture-producing substances such as tobacco. Substances in this class: Arsenic, Aniline, Barium Oxide, Phenol, Nicotine, Lead, Cyanide, Mercury products etc.

. CLASS 6.2      INFECTIOUS SUBSTANCES: These substances cause diseases because they contain microbes. They should be stacked away from food, beverages, accommodations. The nearest health authority should be notified in dangerous situations. Substances in this class :Bone, Bone Fat, Compressed Meat Wastes, Animal Skins, Blood Powder, etc.

CLASS 7   RADIOACTIVE SUBSTANCES 

These substances are transported in special containers. Containers must be absolutely undamaged. They should preferably be stacked on the deck, away from personnel sites, foodstuffs, undeveloped films, drugs and chemicals.
