Whether fuel tanks need to be placarded depends on the type of fuel, the type of packaging, and the regulatory body involved. For example, diesel fuel in non-bulk packaging is typically not subject to USDOT regulations, and therefore does not require placards. However, when transported in bulk packaging, diesel fuel is often regulated and requires placarding. In addition, there are specific requirements for the identification numbers on multi-compartment tanks, with some sources suggesting that loads containing both gasoline and diesel may need to be placarded separately.

Placarding requirements for fuel tanks vary based on the type of fuel being transported
The placarding requirements for fuel tanks depend on the type of fuel being transported, the quantity of the material, and the type of packaging used. Diesel fuel, for instance, is classified as a flammable liquid and is considered a hazardous material. However, it can be reclassified as a combustible liquid if its flashpoint is at or above 38°C (100°F). When diesel is transported in non-bulk packaging (less than 119 gallons), it is not subject to USDOT regulations, and placards are typically not required. On the other hand, when diesel is transported in bulk packaging, it is regulated and does require placarding.
Similarly, the MultiCube, a transfer tank for diesel fuel transportation, eliminates the need for hazmat placarding as it falls under the exemption specified in 49 CFR 173.150(f). Each of its six independent tanks has a maximum capacity of 105 gallons, meeting the criteria for non-bulk packaging.
In contrast, fuel tanks containing larger quantities of diesel fuel, ranging from 800 to 5,000 gallons, are subject to the Hazardous Materials Regulations (HMR) and require placarding. These tanks are typically strapped or chained to the transport vehicle and are used to power generators, compressors, and other diesel-powered equipment at their destination.
It is important to note that placarding requirements may vary based on local and state regulations. For instance, the requirements for a Hazmat Endorsement, necessary for transporting hazardous materials, can differ from state to state, and certain criminal offenses may disqualify an applicant. Therefore, it is essential to consult local officials and adhere to the specific regulations applicable to the operation.

Bulk packaging requires placarding, while non-bulk packaging typically doesn't
The need for placarding typically depends on whether the fuel tanks are classified as bulk or non-bulk packaging. This distinction is important for the transport and storage of hazardous materials, including diesel fuel.
Bulk packaging refers to the transport of large quantities of chemicals or materials, often shipped together to reduce per-unit costs. This type of packaging typically contains hazardous or non-hazardous materials and is subject to specific regulations and requirements. For instance, in the event of an emergency, first responders need to quickly identify the contents of a container to ensure proper treatment.
Non-bulk packaging, on the other hand, usually refers to smaller quantities and is often not subject to the same regulations as bulk packaging. For example, diesel fuel, a flammable liquid, may be reclassified as a combustible liquid if it has a flashpoint above 38°C. In non-bulk packaging, diesel fuel is generally not subject to hazardous material regulations and does not require placarding.
However, when diesel fuel is transported in bulk packaging, it is regulated and typically requires placarding. This is because bulk packaging often contains hazardous materials that pose risks during handling, storage, and transportation. Placarding helps identify the potential hazards of the contents, guiding safety protocols and emergency response procedures.
It's important to note that the specific regulations and requirements for placarding may vary based on federal, local, and international standards. Additionally, the terms "labels" and "markings" have distinct definitions and applications in the context of bulk and non-bulk packaging, with labels referring to standard diamond-shaped placards indicating hazard types.

The flashpoint of the fuel determines the placard used for multi-compartment tanks
When transporting fuel, it is important to determine whether placards are required for the tanks. This is influenced by factors such as the type of fuel, its packaging, and the regulations in place. In the case of diesel fuel, the requirements for placarding can vary.
For diesel fuel, the need for placards depends on the classification of the fuel and the packaging type. Diesel is typically classified as a flammable liquid, but it can be reclassified as a combustible liquid if its flashpoint is at or above 100° F (38° C). When transported in non-bulk packaging, diesel fuel is generally not subject to hazardous material regulations, and placards are not required. However, when transported in bulk packaging, diesel fuel is regulated and does require placarding. The capacity of the packaging dictates the requirements, with a threshold of 119 gallons distinguishing between bulk and non-bulk packaging.
The flashpoint of the fuel plays a crucial role in determining the placard used, especially for multi-compartment tanks. According to the PHMSA (Pipeline and Hazardous Materials Safety Administration), a multi-compartment tank loaded with multiple liquid petroleum distillate fuels should display the identification number of the fuel with the lowest flashpoint being transported. This means that the placard used on the tank will correspond to the fuel with the lowest flashpoint, indicating the overall hazard level of the contents.
For example, consider a multi-compartment tank transporting diesel fuel and another liquid petroleum distillate fuel with a lower flashpoint. In this case, the tank would be placarded with the identification number corresponding to the fuel with the lower flashpoint, as it presents a greater hazard. This placarding system ensures that the potential risks associated with the fuels are clearly communicated during transportation.
It is important to note that regulations and requirements may vary based on geographical location and specific industry standards. Therefore, it is essential to refer to the relevant authorities and guidelines for the most accurate and up-to-date information regarding placarding requirements for fuel tanks.

UN ID numbers are not required on the ends of multi-compartment tanks
The display of UN identification numbers on vehicles, tanks, or containers is an integral part of hazard communication. Shippers and carriers of hazardous materials are responsible for including identification numbers on shipping papers and package markings. The United Nations (UN) and North American (NA) identification numbers are listed in Column 4 of the hazardous materials table (HMT). The UN ID numbers are used for both international and domestic transportation, while the NA ID numbers are only for domestic transportation.
In most cases, diesel fuel is classified as a flammable liquid, but it can be reclassified as a combustible liquid if its flashpoint is at or above 38° C (100° F). When transported in non-bulk packaging, diesel fuel is not considered a hazardous material and does not require placarding. However, when transported in bulk packaging, it is regulated and requires placarding.
For compartmented cargo tanks carrying different types of fuel, the US DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed a rule in 2016 to update the hazardous materials marking requirements. This proposal was in response to the Protecting our Infrastructure of Pipelines and Enhancing Safety (PIPES) Act, which requires PHMSA to address ID number markings on cargo tanks. According to the proposal, DOT does not require marking the ID number for every type of fuel being transported, only the ID number for the distillate fuel with the lowest flash point.
In the case of hazardous materials with different identification numbers being transported in portable tanks, tank cars, or cargo tanks with multiple compartments, the identification numbers are not required on the ends of the tanks. The identification numbers must be displayed on the sides of such tanks in the same sequence as the compartments containing the materials they identify. This rule applies to tanks with a capacity of 3,785 liters (1,000 gallons) or more, requiring identification numbers on each side and end. Smaller tanks only need identification numbers on two opposing sides.

Petroleum products containing both gasoline and diesel may require separate placards
When it comes to transporting petroleum products that contain both gasoline and diesel, it's important to understand the placarding requirements to ensure compliance with safety regulations. The need for separate placards depends on various factors, including the hazard classification, quantity of materials, and type of packaging used.
Firstly, let's discuss hazard classification. Gasoline is typically classified as a flammable liquid, while diesel can be classified as either flammable or combustible, depending on its flash point. A flash point at or above 38°C (100°F) qualifies diesel as a combustible liquid. This classification is important because it determines the applicable regulations and, consequently, the need for placarding.
Now, let's consider the quantity of materials being transported. The distinction between bulk and non-bulk packaging plays a crucial role in determining the need for placards. Bulk packaging refers to containers with a maximum capacity greater than 119 gallons for hazardous liquids, while non-bulk packaging refers to containers with a capacity of 119 gallons or less. When diesel is transported in non-bulk packaging, regardless of its classification as flammable or combustible, it generally does not require placarding. On the other hand, when transported in bulk packaging, diesel is subject to regulations and does require placarding.
The specific details of the petroleum products being transported are crucial. If the petroleum product contains a mixture of gasoline and diesel, the classification and placarding requirements may vary. In some cases, the mixture may be classified differently from pure gasoline or diesel, which could impact the placarding requirements. It's important to consult the relevant hazardous materials regulations and seek expert advice to ensure compliance.
Lastly, the type of packaging used can also influence the need for separate placards. If the gasoline and diesel are packaged separately within the same shipment, they may have distinct placarding requirements. For example, if the gasoline is in bulk packaging while the diesel is in non-bulk packaging, the gasoline may require placarding, but the diesel may not. It's important to carefully assess the packaging configurations to determine the appropriate placarding needs for each component of the petroleum product.
