What You'll Learn
Diesel fuel is classed as a dangerous good
The classification of diesel fuel as a dangerous good varies depending on the specific regulations and standards in place in a particular country or region. For instance, in Australia, diesel fuel is classified as a C1 combustible substance, which is considered a dangerous good under most state and territory regulations. This classification is based on the fuel's chemical properties, flash point, and potential risks.
The Transportation of Dangerous Goods (TDG) regulations in some countries require that containers holding dangerous materials, including diesel fuel, be marked with TDG placards to indicate the nature of the hazard. These placards provide quick identification of the container contents and hazard class, especially during emergencies or accidental releases. They also inform transportation and loading dock workers about the materials they are handling.
The storage requirements for diesel fuel also reflect its classification as a dangerous good. In Australia, for example, diesel fuel must be stored in compliance with the Australian Standard AS1940-2017, which outlines the safe storage requirements for flammable and combustible liquids. This standard specifies different specifications for indoor and outdoor storage, including the use of safety cabinets or outdoor dangerous goods stores, respectively. The storage requirements are designed to mitigate the potential hazards associated with diesel fuel, such as its flammability.
Overall, while the classification of diesel fuel as a dangerous good may vary depending on the specific regulations and standards in place, it is generally recognized as a substance that requires careful handling, transportation, and storage due to its potentially dangerous properties. Organizations that use diesel fuel should refer to the relevant regulations and standards in their jurisdiction to ensure compliance and maintain safety.

TDG Placards must be displayed on containers of dangerous goods
The Transportation of Dangerous Goods (TDG) regulations require that containers holding dangerous materials be marked to show the nature of the danger. These dangerous materials are defined as any material that presents a danger to life, property, or the environment under normal conditions of transport. TDG placards are diamond-shaped and must be displayed as illustrated by Transport Canada. The UN Number must be displayed within a white rectangle on the primary class label itself or next to the primary class.
The TDG Regulations require dangerous goods marks to be displayed on a means of containment containing dangerous goods in transport. A dangerous goods mark can be a label, placard, orange panel, sign, mark, letter, word, number, or abbreviation, or any combination of these things. The size of the placard can be reduced to 100 mm per side if the size or irregular shape of the container does not allow for a larger size. The only exception is for Class 7, Radioactive Materials, whose placard and label cannot be reduced under any circumstances.
The primary class placard for each of the dangerous goods contained in a large means of containment, other than a vessel or an aircraft, must be displayed on each side and each end of the large means of containment. If two or more dangerous goods have different UN numbers but are identified by the same placard, the placard is required to be displayed only once on each side and on each end. In the case of a large means of containment that is a trailer unit, the placard may be displayed on the front of the vehicle attached to the trailer unit.

Diesel fuel has a higher flash point than gasoline
Diesel fuel is considered to be less volatile than gasoline due to its higher flashpoint, which typically ranges between 52 to 93 degrees Celsius (126 to 200 degrees Fahrenheit), with some sources giving a maximum value of 96 °C (205 °F). Gasoline, on the other hand, has a significantly lower flashpoint of -43 degrees Celsius, making it more volatile and prone to ignition.
The flash point of a material is defined as the lowest temperature at which vapours are produced in sufficient quantities to form an ignitable mixture with air. This distinction is crucial, as it determines the ease of ignition and the safety implications associated with the fuel. Diesel, with its higher flashpoint, is less likely to ignite under typical storage and handling conditions, making it safer to transport and handle than gasoline.
The difference in flash points between diesel and gasoline is due to their distinct ignition requirements. Gasoline, also known as petrol, is used in spark-ignition engines, where the fuel-air mixture is ignited by a spark plug. To function effectively, gasoline must have a low flash point to ignite with the spark. However, to prevent preignition caused by residual heat, it also needs a high autoignition temperature.
In contrast, diesel fuel is designed for compression-ignition engines. In these engines, air is compressed to increase temperature, and then the diesel fuel is injected as a high-pressure spray. Since diesel engines lack an external ignition source, diesel fuel can have a higher flash point while still functioning effectively. However, to avoid preignition from compression heating, diesel fuel must have a low autoignition temperature.
The understanding of flash points is not just a technical detail but carries significant safety implications for the petroleum industry and industries reliant on diesel fuel, such as transportation and heavy machinery. It guides the design of storage facilities and the choice of transportation methods, ensuring the safety of workers and the environment. Additionally, knowledge of flash points helps establish fire safety protocols and select the appropriate firefighting methods and equipment for potential emergencies.

No need for double-walled IBCs for diesel fuel
Diesel fuel is classed as a dangerous good, and as such, it must be handled and transported with care. Transportation of Dangerous Goods (TDG) regulations require that containers holding dangerous materials be marked to indicate the nature of the danger. This is to ensure the safety of individuals and the environment in the event of an accident or emergency.
Intermediate Bulk Containers (IBCs) are large, industrial containers used for the transportation and storage of bulk liquids. They are often used for hazardous liquids and are subject to strict regulations and inspections to ensure they are secure and do not leak. While double-walled IBCs provide extra protection and are ideal for storing fuel, they are not always necessary for diesel fuel.
Single-walled IBCs can be safely used for diesel fuel as long as they meet the necessary regulations and standards. For example, Western Global's TransCube range is IBC-compliant and designed for safe, portable fuel storage without leaks or spillages. Additionally, IBCs from companies like Western Global and elmag.eu are manufactured to meet local and global testing standards, ensuring safe and compliant bulk fuel storage.
It is important to note that IBCs must be regularly inspected and maintained to ensure they remain in good condition and comply with regulations. This includes checking for corrosion, stress cracks, or damaged welds, as well as conducting leakproof tests. Proper handling, storage, and transportation of IBCs are also crucial to ensure safety and compliance.
In conclusion, while double-walled IBCs provide extra protection, they are not always necessary for diesel fuel. Single-walled IBCs can be safely used as long as they meet the required standards, regulations, and inspections. However, it is essential to prioritize safety and comply with all relevant guidelines when handling and transporting diesel fuel.
