Definition
The International Carriage of Dangerous Goods by Road (ADR) is a set of regulations that govern the transportation of hazardous materials by road. These regulations ensure the safe and secure transport of dangerous goods, protecting the environment and the public from potential hazards.
Background
The ADR was developed by the United Nations Economic Commission for Europe (UNECE) and was first adopted in 1957. It has since been updated and revised multiple times to keep up with advancements in technology and changes in the transportation industry.
Scope
The ADR applies to all road transport of dangerous goods. It covers all aspects of the transport process, from packaging and labeling to vehicle requirements and driver training.
Classification of dangerous goods
The ADR classifies dangerous goods into nine classes based on the type of hazard they pose:
- Class 1: Explosives
- Class 2: Gases
- Class 3: Flammable liquids
- Class 4: Flammable solids, substances liable to spontaneous combustion, and substances that emit flammable gases when in contact with water
- Class 5: Oxidizing substances and organic peroxides
- Class 6: Toxic and infectious substances
- Class 7: Radioactive materials
- Class 8: Corrosive substances
- Class 9: Miscellaneous dangerous substances and articles
Requirements for transport
The ADR sets out specific requirements for the packaging, labeling, and documentation of dangerous goods being transported by road. It also specifies the types of vehicles and equipment that must be used for different classes of dangerous goods.
Driver training and safety measures
The ADR requires all drivers involved in the transport of dangerous goods to undergo specialized training and obtain a dangerous goods safety adviser (DGSA) certificate. This training covers topics such as recognizing and responding to hazards, emergency procedures, and safe handling and storage of dangerous goods.
Conclusion
The ADR plays a crucial role in ensuring the safe and secure transport of dangerous goods by road. By setting strict regulations and standards, it helps to protect the environment and the public from potential hazards. It is important for all parties involved in the transport of dangerous goods to adhere to these regulations to prevent accidents and protect public safety.
