Classification of Dangerous Goods
The classification of dangerous goods is a fundamental aspect of ensuring their safe transport by road. Dangerous goods are substances or materials that pose significant risks to health, safety, property, or the environment during transport. To manage these risks effectively, dangerous goods are categorized into specific classes based on the type of hazard they present. This classification system is internationally recognized and is crucial for determining the appropriate handling, packaging, and labeling requirements.
Each dangerous good is assigned a unique UN number, which serves as an identifier for the substance or material. Along with this number, a proper shipping name is used to describe the goods during transport. These identifiers are critical for ensuring the correct handling and emergency response procedures are followed.
1. Class 1: Explosives
This class includes substances and articles that can explode or cause a rapid release of gas and heat under certain conditions.
Examples of Class 1 and their UN number:
- UN 0027: Dynamite
- UN 0336: Fireworks
- UN 0009: Ammunition
2. Class 2: Gases
Gases that are compressed, liquefied, or dissolved under pressure. They can be flammable, non-flammable, toxic, or corrosive.
Examples of Class 2 and their UN number:
- UN 1978: Propane
- UN 1072: Oxygen, compressed
- UN 1017: Chlorine
3. Class 3: Flammable Liquids
Liquids that can easily ignite and burn, creating fire hazards during transport.
Examples of Class 3 and their UN number:

8. Class 8: Corrosive Substances
Substances that can destroy or irreversibly damage other materials, including human tissue, on contact.
Examples of Class 8 and their UN number:
- UN 1830: Sulfuric acid
- UN 1789: Hydrochloric acid
- UN 1823: Sodium hydroxide, solid
9. Class 9: Miscellaneous Dangerous Goods
Goods that present a danger during transport but do not fit into the other classes. This includes environmentally hazardous substances and items with other specific risks.
Examples of Class 9 and their UN number:
- UN 3480: Lithium-ion batteries
- UN 1845: Carbon dioxide, solid (dry ice)
- UN 2212: Asbestos, amphibole (amosite, tremolite, actinolite, anthophyllite, crocidolite)
Legal Requirements and Regulations for transporting dangerous goods by road
The transportation of dangerous goods by road is governed by a complex framework of legal requirements and regulations designed to ensure safety and minimize risks. These regulations are enforced at both international and national levels, and they impose specific obligations on all parties involved in the transport process, including shippers, carriers, and consignors. Understanding and complying with these regulations is crucial for legal and operational safety.
1. International Guidelines: ADR Agreement
The European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) is a key international treaty that regulates the transport of dangerous goods across European borders. It sets out requirements for classification, packaging, labeling, and documentation.
ADR applies to all member states of the agreement and influences the transport regulations in non-member countries as well. It covers everything from the design and construction of transport vehicles to the training of personnel involved in the transport of dangerous goods.
2. National Regulations and Compliance
While ADR provides a framework for international transport, each country may have its own specific regulations that supplement or differ from ADR guidelines. For example, in the US, the Department of Transportation (DOT) regulates hazardous materials through the Hazardous Materials Regulations (HMR).
Many countries require special permits or licenses for transporting certain classes of dangerous goods. These permits ensure that the carrier has the necessary qualifications and equipment to transport hazardous materials safely.
3.Local Regulations
In addition to national regulations, local laws may impose further restrictions, such as designated routes for hazardous materials, curfews, or additional documentation requirements.
Packaging and Labeling Requirements
The packaging and labeling of dangerous goods are critical components of safe transport, ensuring that these materials are securely contained and easily identifiable throughout their journey. Compliance with these requirements not only protects those handling the goods but also helps prevent accidents that could have serious consequences for public safety and the environment.
Packaging Requirements
- UN Approved Packaging: Use only UN-certified containers for dangerous goods.
- Packaging Types: Choose the right type, like drums or boxes, based on the material.
- Drop Test: Packaging must pass a drop test to ensure it won’t break.
- Stack Test: Ensure packaging can bear weight when stacked.
- Leakproof Test: Packaging must be leakproof to prevent spills.
- Material Compatibility: Packaging materials must not react with the goods.
- Sealing and Closure: Ensure all containers are tightly sealed and secure.
Labeling and Marking Standards
- Hazard Labels: Display a primary hazard label for each dangerous good.
- Subsidiary Labels: Use additional labels for goods with multiple hazards.
- UN Number: Clearly mark the UN number on the package.
- Proper Shipping Name: Include the proper shipping name on the package.
- Handling Marks: Add handling instructions like “Keep Upright.”
- Vehicle Placards: Place placards on all four sides of vehicles transporting dangerous goods.
- Mixed Loads: Use multiple or mixed load placards for different hazards.
Documents required for road transport of dangerous goods
Proper documentation is crucial for the safe and compliant transport of dangerous goods by road. These documents provide essential information about the nature of the goods, handling procedures, and emergency measures, ensuring that all parties involved are informed and prepared. Here are the key documents required:
- Dangerous Goods Declaration: Confirms compliance with regulations and includes the UN number, shipping name, and hazard class.
- Transport Document: Accompanies the shipment and lists consignor, consignee, quantity, and handling instructions.
- Safety Data Sheets (SDS): Provides hazard information and emergency procedures, including first aid and firefighting measures.
- Emergency Contact Information: Ensures quick access to contacts for shippers and responders, listing essential phone numbers.
- Certificate of Packaging Conformance: Certifies packaging standards, detailing the type, materials, and test results.
- Driver Instructions and Training Records: Confirms driver training and includes specific handling and emergency response instructions.
- Container/Vehicle Packing Certificate: Certifies proper loading, listing stowage details and securing methods.
- Incident Report Form: Documents transport incidents, detailing the event, actions taken, and any resulting damage or injuries.
- Permits and Licenses: Legal authorization for transport, including specific permits for high-risk goods.
- Record Keeping Requirements: Ensures documentation is stored for future reference, including all transport and training records.
Vehicle and Equipment Standards for Transporting Dangerous Goods by Road
Transporting dangerous goods by road freight requires adherence to strict vehicle and equipment standards to ensure safety and regulatory compliance.
Vehicles must be specifically designed or equipped for the type of dangerous goods being transported, featuring robust construction to withstand physical and chemical hazards.
Regular maintenance and inspections are essential to keep vehicles in safe working condition, with documented records of all maintenance activities.
Safety equipment, including appropriate fire extinguishers, spill kits, and first aid kits, must be onboard and in good working order.
Vehicles should be equipped with communication devices for constant contact with dispatchers and emergency services, and an emergency response plan should be readily accessible.
Proper marking and placarding, including hazard placards and matching labels, are necessary for clear hazard communication.
Dangerous goods must be securely loaded and segregated to prevent shifting and reactions, and drivers must be trained and certified in handling hazardous materials.
All documentation must be up-to-date and accessible.
For liquid goods, tank vehicles should be designed to prevent leaks, while container vehicles must securely transport solids and packages.
