According to the Federal Institute for Risk Assessment, the register of internationally classified dangerous goods has 3,500 entries. When do goods pose a danger? What is a dangerous goods?
If dangerous goods are transported by road, rail, water or air, a dangerous goods safety advisor must be appointed. But which goods fall into the category of dangerous goods? Around 3,500 substances are listed in the catalog of dangerous goods with their UN number and must be handled with special care and under regulations, such as documentation, during transport or storage.
The classification of dangerous goods is regulated internationally according to model regulations of the United Nations. For transports across the border, uniform markings of dangerous goods transports are intended to increase safety. We will show you how dangerous goods are classified and how you can benefit from external dangerous goods safety advisors.
What is dangerous goods?
According to the law on the transport of dangerous goods also Gefahrgutbeförderungsgesetz (GGBefG), the definition of “dangerous goods” is met for substances and objects if they:
“by reason of their nature, characteristics or condition, in connection with the carriage, may present hazards to public safety or order, in particular to the general public, to important public property, to human life and health, and to animals and property.”
This “danger” for humans, animals and the environment emanates from many different substances. The classification of dangerous goods of the UN has prevailed, which divides dangerous goods into classes and prescribes a model for the labeling. I.e. every good that has a UN number is considered dangerous goods!
But where do you find the UN number? You can sometimes find it on the goods themselves – but the UN number doesn’t have to be there. The only reliable source is the safety data sheet. There you can find the UN number in the transport section.
Conversely, goods without a UN number are NOT dangerous goods.
What are the classes of dangerous goods?
There are 9 different classes of dangerous goods with subclasses, which are marked separately and for the transport of which certain regulations and precautions must be observed.
We show which dangerous goods classes there are and which examples of dangerous goods are in the class.
Dangerous goods class 1 – explosives
The class includes explosives and articles containing explosives.
Dangerous goods class 1 is subdivided into further subclasses. These depend on the sensitivity during transport and the effects in the event of an explosion.
Examples of dangerous goods of the class: TNT, airbags
Dangerous goods class 2 – gases
This class distinguishes between gases that are flammable (Class 2.1), non-flammable (Class 2.2) or toxic (Class 2.3).
Examples of dangerous goods of the class: helium, neon, nitrogen
Dangerous goods class 3 – Flammable liquids
Flammable or combustible are all substances that catch fire even when exposed to relatively low heat (low flash point).
Examples of dangerous goods of the class: gasoline, diesel, fuel oil, alcohol.
Dangerous goods class 4 – Flammable solids
Three subclasses are found in class 4:
Class 4.1 Flammable solids,
Class 4.2 Substances liable to spontaneous combustion
Class 4.3 Substances which form flammable gases with water
Examples of dangerous goods of the class: aluminum powder, phosphorus, calcium carbide.
Dangerous goods class 5 – flammable substances / oxidizing substances
There are two subclasses in dangerous goods class 5:
Class 5.1 Flammable (oxidizing) substances
Class 5.2 Organic peroxides
Examples of dangerous goods of the class: oxygen, cross-linking agents in the rubber industry
Dangerous goods class 6 – Toxic substances
There are two subclasses in grade 6:
Class 6.1 Toxic substances
Class 6.2 Infectious substances
Examples of dangerous goods of the class: agents for pest control, hospital waste.
Dangerous goods class 7 – Radioactive materials
This group includes all substances that emit radioactive, i.e. spontaneously ionizing, radiation.
Examples of dangerous goods in the class: spent fuel rods, medical equipment or medicines.
Dangerous goods class 8 – Corrosive substances
Substances in this class are corrosive due to their acidic or basic pH.
Examples of dangerous goods of the class: sulfuric acid
Dangerous goods class 9 – other dangerous substances and articles
This “catch-all” class contains hazardous substances that cannot be assigned to any other category.
Examples of dangerous goods of the class: asbestos, lithium batteries (class 9A)
Other classes subject to labeling:
- Environmentally hazardous substances
- Marking for materials transported in a heated state
What makes a hazardous material a dangerous goods?
Basically, hazardous materials and dangerous goods are not the same!
A substance is referred to as a hazardous MATERIAL if it poses a risk during use or storage. The legal basis is formed by the Hazardous Substances Ordinance and the Water Resources Act in the broader sense.
An object or substance is classified as a dangerous good if it poses a particular hazard during transport. In concrete terms, this means that in the event of a (traffic) accident, for example, further hazards emanate from a substance or object, for example because it is highly flammable or under pressure. The legal basis here is formed by the dangerous goods regulations of the respective transport carriers (ADR, GGVSEB, GGVSee, …). We explain the difference between hazardous substances and dangerous goods in detail in the blog article.
Different dangerous goods regulations per mode of transport
Agreements and regulations on the transport of dangerous goods are divided by mode of transport. There are regulations for the transport of dangerous goods by road, rail, air, sea or inland waterway. These apply internationally, within the UN or even worldwide. The agreement on the transport of dangerous goods by road (ADR) alone is recognized in more than 50 countries.
In addition to the international regulations, however, there are also special national regulations that are anchored in the respective national law, e.g. in Germany in the Dangerous Goods Ordinance for Road, Rail and Inland Navigation (GGVSEB). For example, for the transport of dangerous goods on the Danube.
Each mode of transport has its own dangerous goods legislation:
- Dangerous goods road: International Agreement concerning the International Carriage of Dangerous Goods by Road (ADR).
- Dangerous goods rail: Regulations concerning the International Carriage of Dangerous Goods by Rail (RID)
- Dangerous goods by sea: transport of dangerous goods by sea-going vessels (IMDG)
- Dangerous goods inland waterways: transport of dangerous goods by inland waterways (ADN)
- Dangerous goods air freight: International IATA Dangerous Goods Declaration
Checklist – What is dangerous goods?
If you are transporting hazardous materials, you may be subject to regulations governing the transportation of dangerous goods. To determine them, you need to analyze the type of goods and their quantity:
Is there a UN number?
If the safety data sheet of the product contains a UN number, then it is a dangerous goods. There you can also find out which dangerous goods class it is assigned to. The type of labeling and packaging to be used can be found in the dangerous goods tables of the respective regulations ADR, AND, RID IMDG or IATA. Any special regulations can also be found there. You are unsure or would like support from a professional? Then please contact us!
No UN number is assigned to the product? Then it is NOT dangerous goods. It’s that simple!
In what quantities are dangerous goods transported?
Depending on the quantity and UN number of the dangerous goods transported, special regulations can be applied that offer relief. For example, the regulations on limited quantity, the 1000 point rule, exemptions or exceptions for certain occupational groups.
Whether and which special regulations and facilitations apply in a specific case can basically be found out by looking up the respective tables in the legal texts of ADR, AND, RID, IMDG or IATA. Caution applies to own interpretations: Real legal certainty can only be obtained from experienced dangerous goods safety advisors. In many cases, the appointment of a dangerous goods safety advisor is even mandatory!
