Imco Degrees

Class 1.1: Mass and Explosion

It contains explosives that can cause a mass explosion. It affects almost all loads during an explosion.

Class 1.2: Throwing Pieces, but Not Exploding in Mass

Contains explosives that are at risk of launching parts but will not cause a mass explosion.

Class 1.3: Flaming Blasts

Includes explosives that have a risk of fire, slight explosion severity, a small risk of throwing parts, but will not cause mass explosions.

Class 1.4: Low Harm Explosives

Includes explosives with a slight risk of explosion, the effects of which will not exceed the container, which will not cause an explosion or fire outside.

Class 1.5: Difficult to Explode but Can Explode in Mass

Includes explosives that can explode in mass but very hard to explode.

Class 1.6: Hard to Explosion and Non-Explosive Hazards in Mass

It includes explosives that can explode very hard, have low sensitivity and also do not have a mass explosion hazard.

Class 2.1: Flammable Gases

These are substances which are 454 kg (1001 lbs) and are in gaseous state below 20 ° C (68 ° F). The pressures of these substances are 101.3 kPa (14.7 psi) and the boiling points under this pressure are 20 ° C (68 ° F) or below. They are flammable at 101.3 kPa (14.7 psi) pressure and air mixtures below 13%. Or they are flammable in at least 12% air mixture and 101.3 kPa (14.7 psi) pressure regardless of the lower limit.

Class 2.2: Flammable and Nontoxic Gases

This class includes pressurized gases, liquefied gases, pressurized cryogenic gases, compressed gases contained in a solution inert and oxidizing gases. Flammable and non-toxic gases are gases not included in class 2.1 and 2.3 with a pressure content of 280 kPa (40.6 psia) at a temperature of 20 ° C (68 ° F).

Class 2.3: Toxic Gases

It is known to be harmful to human health and creates health hazard during transportation.
Toxic gases are found at temperatures of 20 ° C and below, 101.3 kPa pressure (boiling points under this pressure of 20 ° C or below), although the hazards to human health are not strictly proven, they are substances with an LC50 value above 5000 ml / m3 in animal tests.

Flammable liquids are substances with a flash degree of not more than 60.5 ° C (141 ° F), or in a liquid state, heated for transport and a flash degree of 37.8 ° C (100 ° F) and above.

Class 4.1: Flammable Solids

Flammable solids as they are. These substances can ignite by friction and their burning rate is more than 2.2 mm (0.087 inch) per second. Metal powders that can ignite and react in 10 minutes or less are also included in this class.
Substances which are thermally unbalanced, have a strong exothermic reaction without air participation and are self-igniting are also in this category.
These are explosives that belong to class 1 but have been removed, or substances specifically included in this class by the manufacturer.

Class 4.2: Self-Flammable Solids

Spontaneously flammable substances are pyrophoric substances. These are substances that ignite in the fifth minute of contact with air or heat up without the need for an additional energy source when in contact with air.

Class 4.3: Hazardous Persons When Contacting Water

These substances are substances that produce flammable or poisonous substances in contact with water. Hazard measure is to extract more than 1 Liter of gas per hour for 1 kg of substance.

Class 5.1: Oxidizing Agents

These are substances that secrete or accelerate other substances by releasing oxygen to this type of substance.

Class 5.2: Organic Peroxides

Organic peroxides (Class 5.2) are substances that contain oxygen in the form of O-O. These can be considered as a derivative of hydrogen peroxide, they are produced by replacing one or more hydrogen atoms in the water with organic radicals.

Class 6.1: Toxic (Toxic) Substances

Substances known to be harmful to humans during transport are classified as toxic substances. In addition, substances that are found to be poisonous in the plants made on animals are considered as dangerous for humans and included in this category.

Class 6.2: Microbe Contaminants

Infectious diseases are substances known or suspected to carry a pathogen. Pathogens are microorganisms (bacteria, viruses, fungi, etc.) or other factors that cause disease in animals or humans.

Radioactive

Substances bearing the yellow RADIOACTIVE III (LSA-III) label. In some radioactive substances, even if this label is not used, they should have a poster showing radioactivity.

corrosive

These are substances that have an abrasive and thickness reducing effect on human skin in contact for a certain period of time. Substances that have an abrasive effect on steel and aluminum also enter this class.

Other Hazardous Substances
Substances that are dangerous during transportation but do not comply with any of the defined classes are included in this class. This class includes the following items: – Anesthetic or other types of harmful substances. These are substances that may cause discomfort to the flight crew or ship crew, which prevent them from performing their duties.
