What is your classification in transport?


Today we will tell you everything dangerous goods. Let’s first define this term. Next, we’ll go over the different categories and types of dangerous goods that exist. We will discover more subdivisions than we usually take into account. Let’s get started!

Definition of dangerous goods

Many products that reach our consumption were previously treated by logistics as dangerous goods. We can think of drugs, drugs, cleaning products, or gases and fuels, such as gasoline and coal. In addition, chemicals with harmful effects on health or the environment are treated with extreme care.

Dangerous goods are defined as any material that may present a risk to human health or the environment. It should also be noted that a commodity becomes dangerous when it exists a rule that determines it.

Currently, we find over 12,000 substances that are considered dangerous goods. To facilitate handling and classification, they are divided into 9 groups.

Classification of dangerous goods

1 – Explosives

The explosions come from a rapid change in the state of molecules. In general, it is generally from the solid state to the gaseous state. For example, if we heat certain liquids such as gasoline, it explodes.

There are 6 subdivisions here that correspond to different types of explosives. These items are assigned different letters as established by the compatibility group. These allow carriers to know the Explosive substances which can be carried together and which cannot. In addition, we find the subdivisions:

  1. Risk of massive explosion
  2. Risk of projection
  3. Possibility of fire and slight explosion or slight risk of projection
  4. Minimal risk
  5. Explosive agents
  6. Very insensitive triggers

2 – Gas

They are dangerous goods because are transported under high pressure. This can greatly reduce its volume, thus saving storage space. However, this generates a very high risk, because if this gas is released suddenly, it emits a strong pressure. In this way, can explode your containers and cause a lot of damage. In addition, there are gases which can become flammable or poisonous.

There are three gas subdivisions here:

  1. Flammable
  2. Non-flammable, non-toxic
  3. Toxic

3 – Flammable liquids

Those which derive mainly from petroleum such as gasoline or kerosene have a high risk of flammability. Other liquids of natural or artificial origin are also added, such as the different types of alcohol.

dangerous goods

The danger of these substances lies in the steam emission they work with heat. When they are mixed with air and if they reach a high temperature, they can catch fire or explode. The most dangerous substances in this group are those with a very low evaporation point.

There are also subdivisions, although in this case they are classified according to the packaging that the materials require. The different packing groups are:

  • I: boiling point less than 35 ° C
  • II: boiling point above 35 ° C and flash point (or evaporation) below 23 ° C
  • III: boiling point above 35 ° C and flash point (or evaporation point above 23 ° C.

4 – Flammable solids, spontaneous combustion materials and dangerous in contact with water

Within this group of dangerous goods we find 3 different groups:

Solids flammable, which are self-reactive solids and desensitized explosives. This type is made up of materials that ignite more easily than ordinary fuel such as paper or wood. Its combustion is generally violent, rapid and reaches very high temperatures. An example of this commodity could be the TNT.

Also in this category we find elements that burn spontaneously on contact with oxygen. They are always stored in airtight containers or with a liquid coating that insulates them from contact with air.

Finally, enter the materials which, in contact with water, emit flammable gases. The reaction generated on contact with water may be sufficient to ignite transported contents. The only way to transport these goods is to use airtight containers that isolate them from moisture and water vapor.

5 – Oxidizing agents

These are materials with a high oxygen content. These materials can react with others flammable materials and start to burn. A high oxygen content causes violent combustion which is difficult to extinguish. Because? Because combustion does not require oxygen from the air to fuel the fire since these products already contain large amounts of oxygen. The most common of these are fertilizers used in agriculture.

6 – Toxic and infectious substances

In this subdivision we find chemical elements and poisons that can be seriously harmful for human health and the environment. When transporting this type of material, the operators in charge must ensure that they do not ingest or breathe the substances or their vapors. Also, do not allow their contact with the outside world. It is therefore important to have packaging suitable for this type of product, as for all.

7 – Radioactive

Are those materials made up of unstable atoms. These change their structure randomly and spontaneously every certain period of time. Thus, radiation is generated which can cause damage to living things that are exposed to it for a long time. They must be transported by packaging capable of isolating radiation emitted by the bodies they contain inside.

dangerous goods

8 – Corrosive

We hear by corrosive materials all these substances that cause damage to all the tissues (usually living) with which it comes into contact, and even destroy them. While the toxic elements we discussed in Group 6 destroy the tissues of an organism from the inside, the corrosive elements work from the outside.


Dangerous goods require a significant commitment. Therefore, in Trade Journal we work with responsibility and professionalism for a quarter of a century, becoming a leading company in the sector. Our clients already know the great commitment and dedication that characterizes us, and that is why they continue to choose us. And you, what are you waiting for? We are here to advise you!
