Class 3 dangerous goods consist of flammable liquids that can ignite easily and pose serious risks during storage, handling, and transport. Improper management of these substances can lead to property and cargo damage, personal injury, environmental harm, insurance invalidation, and even criminal prosecution. Understanding their characteristics and following strict safety guidelines is essential to ensure compliance and protect people, assets, and the environment.
Common Types and Classification of Class 3 Dangerous Goods
Class 3 dangerous goods include a wide range of commonly used flammable liquids across industrial, commercial, and consumer sectors. Typical examples include alcohol-based products such as methanol and ethanol; fuels like petrol, gasoline, kerosene, and diesel; industrial products including adhesives, paints, turpentine, printing inks, varnishes, and perfumery items; and solvents such as methyl ethyl ketone (MEK) and acetone.
These liquids are classified into Packing Groups I, II, and III based on their flash point and boiling point, which indicate the level of danger they present. Some substances, such as paint, may fall into more than one packing group depending on their formulation. Correct classification is critical, as it determines packaging, labeling, storage, and transport requirements.
Key Handling, Storage, and Transport Guidelines
Safe management of flammable liquids begins with proper packing. Only approved tanks or packaging should be used, ensuring containers are undamaged, uncontaminated, and never overfilled. Spill response equipment must always be available, and ignition sources strictly controlled.
During storage, flammable liquids should be kept in well-ventilated, temperature-controlled areas, away from heat and ignition sources, and preferably close to ground level. Regular inspections are essential, and staff must be trained in emergency response procedures. Any issues should be promptly reported to the designated dangerous goods (DG) competent person.
When transporting Class 3 goods, cargo must be segregated from incompatible materials, securely fastened, and handled in accordance with the CTU Code and manufacturer’s instructions. Permissions may be required when moving through public or built-up areas. Throughout handling operations, exposure to extreme temperatures must be avoided, cargo should never be dropped, dragged, or mishandled, and clear communication across the supply chain is vital.
Class 3 dangerous goods play a crucial role in many industries, but their flammable nature demands rigorous control measures. By correctly classifying these substances, using approved packaging, maintaining safe storage conditions, and following strict handling and transport procedures, organisations can significantly reduce risks. Adhering to these best practices not only ensures regulatory compliance but also safeguards lives, property, and the environment.
