Classification and identification
Dangerous goods are systematically categorized based on the hazards they present. Each hazardous product receives a unique UN code consisting of four numbers, displayed in an orange box outlined in black for easy identification. The classification system includes nine main categories and various sub-categories, covering explosives, flammable gases and liquids, toxic substances, infectious materials, and radioactive agents. This standardized approach ensures consistent handling and risk management across different transportation modes and international borders.
Regulatory framework
Transportation of dangerous goods operates under strict regulatory oversight that varies by mode of transport. Road transportation follows the European Agreement concerning the International Carriage of Dangerous Goods (ADR), ratified by 49 countries. Rail transport is governed by separate international regulations specific to railway operations. The United Nations plays a crucial role in harmonizing national regulations to facilitate safe multimodal transport across borders.
Safety requirements and specialized handling
Each dangerous product requires specific equipment for packaging, handling, transport, loading, unloading, and inspection. All personnel involved in dangerous goods transportation, including vehicle drivers, must complete specialized training at certified centers to ensure proper safety procedures are followed throughout the logistics chain.
Incident reporting and prevention
In countries like France, legislation mandates comprehensive accident reporting for incidents involving dangerous goods. Companies must submit declarations to relevant authorities such as the MTMD (dangerous goods transportation division) or ASN (nuclear safety authority) using standardized forms like Cerfa form no. 12252. These reports include detailed analysis of accident causes and preventive measures to avoid future occurrences. The company’s safety advisor, responsible for transport equipment preparation, typically handles these declarations, ensuring continuous improvement in safety protocols and risk mitigation strategies.
