Hazardous Materials
The term hazardous materials is applied to all substances and objects whose transport may represent a potential threat to the environment, humans, animals and public safety and order. The transportation of hazardous materials is therefore subject to various legal regulations depending on the mode of transport. The regulations concerning classification for the relevant mode of transport determine whether a substance or object is a hazardous material. Differences are made between the following modes of transport:
- Road (ADR)
- Rail (RID)
- Inland waterway (ADN))
- Ocean (IMDG Code)
- Air (IATA-DGR)
Efforts aimed at harmonization mean that the regulations governing classification for the various modes of transport are being brought into line. However, differences still exist.
ADR/RID divides hazardous materials in to 13 categories of dangerous goods:
| Class | Class description |
|---|---|
| 1 | Explosive materials and objects |
| 2 | Gases |
| 3 | Flammable liquids |
| 4.1 | Flammable solids |
| 4.2 | Spontaneously combustible solids |
| 4.3 | Substances that emit a flammable gas when wet or react violently with water |
| 5.1 | Inflammatory (oxidizing) agents |
| 5.2 | Organic peroxides |
| 6.1 | Poisonous substances |
| 6.2 | Biohazardous substances |
| 7 | Radioactive substances |
| 8 | Corrosive substances |
| 9 | Miscellaneous substances and objects |
