The safe transportation of dangerous goods in the logistics and transportation industry is both a legal obligation and a critical issue for human life and the environment.

Therefore, standards such as ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road) and IMDG (Maritime Dangerous Goods Codes) are applied in international transportation.

Below is the classification of hazardous materials , examples of substances found in each class, and safe stacking rules.

 

 

1 – Explosives

Explosives react suddenly with high pressure and temperature, creating an explosive effect.

Stowage: On ships, they are stored under hatch covers, away from crew areas and the hull.

Examples: Black powder, cartridges, smoke bombs, ammunition, dynamite.

 

Class 2 – Gases

2.1 Flammable Gases Gas )

Keep away from heat sources and personnel areas.

Examples: Acetylene, ethane , ethylene, methane, hydrogen, lighter fluid.

Toxic Gases Gas )

Store away from heat sources, personnel areas, and foodstuffs.

Examples: Ammonia, fluoride, prussic acid, chloride, carbon monoxide.

Non-Flammable Compressed Gases Compressed Gas )

Store in well-ventilated, cool areas. Risk of explosion due to pressure increase when heated.

Examples: Argon, helium, carbon dioxide, coal gas, oxygen.

 

Class 3 – Flammable Liquids

It is divided into 3 subclasses according to its flash point:

• 3.1 Gasoline: Flash point is below 18°C. Always stowed on deck.
• 3.2 Diesel: The burning point is between 18°C and 23°C. It can be stacked on or below deck.
• 3.3 Diesel: Its burning point is between 23°C and 61°C. It is stored under deck.

 

 

Flammable Solids Solids

4.1 Flammable Solids

Keep away from living areas.

Examples: Aluminum powder, celluloid , naphthalene, red phosphorus.

Spontaneously Combusting Solids Combustible

It is stacked by ensuring air circulation.

Examples: Copra , fish meal, dried grass, charcoal.

4.3 Solids That Burn When Wet (Dangerous When Wet)

They exhibit burning properties when in contact with water.

Examples: Alkaline alloys, barium, carbide, sodium, magnesium.

 

Oxidizing Agents Substances

5.1 Oxidizing Agents

Keep separate from flammable materials.

Examples: Nitrates, artificial fertilizers, ammonium sulfate.

5.2 Organic Peroxides ( Organic Peroxide )

May be flammable or explosive. Should be stored in cool, dry places.

Example: All types of peroxide.

 

Class 6 – Toxic Substances

6.1 Toxic Substances

May be fatal to human health. Should be kept away from food and drink.

Examples: Arsenic, aniline, phenol, nicotine, cyanide, mercury products.

6.2 Biologically Hazardous Materials ( Infectious Substances

Contains disease-causing microorganisms. Health authorities must be informed.

Examples: Bone, blood meal, animal skins.

 

Class 7 – Radioactive Substances

It is transported in special containers, which must be undamaged.

It is stored away from personnel areas, food, and sensitive materials.
