What You'll Learn

Diesel fuel cans are yellow
Colour-coding of safety cans is a valuable safety feature and an effective way to keep people safe from the hazards associated with misusing certain fuels. It is now common practice to coordinate the colour of your safety can with the liquid inside. Diesel fuel cans are yellow. This is an industry standard.
The National Fire Protection Association (NFPA) is the world’s premier organisation with a mission to eliminate deaths, injuries, and property damage due to fire, electrical, and other related hazards. While the NFPA has no enforcement capability, many of its codes and standards are enforceable under OSHA, state, and local regulations.
The use of yellow for diesel fuel cans is also in line with OSHA and NFPA Code 30 requirements. The stark colour contrast from gas cans, which are red, makes it easier to recognise the difference in fuel types and reduces the risk of fuel mixing.
In the UK, the colour coding is different, with green commonly used for gasoline and black for diesel. It is important to be aware of the regulations and practices specific to your location before proceeding.

Gasoline fuel cans are red
While OSHA does not regulate the colour of the container, red gasoline cans are widely adopted as a manufacturer's standard. These cans are also designed and constructed according to strict guidelines put in place by regulatory agencies such as OSHA, EPA, NFPA, and DOT. The colour-coding system is a valuable safety feature that helps prevent confusion and potential mix-ups when handling multiple flammable liquids.
Red gasoline cans are typically marked with the word "GASOLINE" or "GAS" and are equipped with safety features such as no-weld bottoms and spark-proof flame arrestors. These cans are commonly used in warehouses and jobsites where multiple fuels are utilised for trucks, forklifts, and heating equipment.
It is worth noting that the standards for fuel can colours vary across different countries. For example, in the United Kingdom, green is commonly used for gasoline, while diesel is designated by black cans. Therefore, it is crucial to be well-acquainted with the regulations and practices specific to your location before handling fuel cans.
While gasoline fuel cans are typically red, it is not uncommon for them to fade over time, sometimes appearing more yellow in colour. Additionally, some individuals choose to wrap a section of the red gasoline can in yellow duct tape to indicate the presence of gasoline.

Kerosene fuel cans are blue
The colour of a fuel can is not just for aesthetic purposes. Each colour designates a specific type of fuel being stored. This colour-coding system is designed to enhance user safety and eliminate confusion regarding the contents of the can.
Diesel fuel cans are typically yellow. This is also an industry standard. It is important to use containers that are marked properly for the fuel to be stored in them. While diesel cans are usually yellow, some people have reported using red diesel cans without any issues.
Other colours used for fuel cans include red for gasoline and green for oils. These colours make it easy to identify the contents of the can and help prevent accidents caused by mishandling.

Oils are stored in green cans
The use of different colours for different fuels is a widely accepted standard and is recommended to avoid confusion when working. For example, gasoline is stored in red cans, diesel in yellow cans, and kerosene in blue cans. It is important to note that these standards are not universal, and certain places will use colours to designate different chemicals, operating on a system specific to their workplace. For example, in the UK, green is used for gasoline and black for diesel.
It is always best to use containers that are marked properly for the fuel to be stored in them. In addition to colour-coding, safety cans are designed and constructed according to strict guidelines put in place by regulatory agencies, with the goal of reducing injuries from using flammable substances.
While the use of colour-coding is a valuable safety feature, it is important to also clearly label oil cans with their specific contents. Oils can vary greatly, and the characteristics and composition of the oil within the can should be labelled clearly on the outside to avoid any confusion. When you see a green can, always read the label rather than assuming it is an oil with the exact composition you are looking for.
Furthermore, it is important to be well acquainted with the regulations and practices specific to your location before proceeding, as the laws and guidelines surrounding safety can colours are followed most closely in the United States.

Diesel fuel cans vary by country
The colour of diesel fuel cans varies by country and even by state. In the United States, diesel is widely assumed to be stored in yellow cans, with red cans being reserved for gasoline. However, some states may have different standards. For example, in the UK, green is commonly used for gasoline and black for diesel.
The colour-coding of safety cans is a valuable safety feature and an effective means of keeping people safe from the hazards associated with misusing certain fuels. It also provides clarification for first responders in the event of an accident. For instance, the National Fire Protection Association (NFPA) addresses the safe handling and use of flammable liquids, including safety can use.
In addition to colour-coding, safety cans are designed and constructed according to strict guidelines put in place by regulatory agencies, with the goal of reducing injuries from using flammable liquids. These cans should always be clearly labelled to avoid confusion.
The price of diesel fuel also varies across different states and cities. Taxes are a major reason for this discrepancy, as states tax gasoline at different rates, often depending on how much money each state needs to raise in highway funding. Other factors include emissions regulations, refinery maintenance, the switch to summer blend gas, and fluctuations in consumer demand. For example, fuel prices tend to be steeper in areas like the Northeast and West Coast, which rely more on imported oil.
Therefore, it is essential to be aware of the regulations and practices specific to your location when dealing with diesel fuel cans and their colours.

The yellow color is used to distinguish diesel from gasoline, which is stored in red cans. The stark color contrast makes it easier to recognize the difference in fuel types and reduces the risk of fuel mixing.
Blue cans are used for kerosene, a common fuel in the aviation industry. Kerosene is less volatile than gasoline and diesel, hence the use of a calming color. Green cans are used for mixed fuels and oils.
Yes, fuel cans should also have identification markings on the container and the spill-proof spout. It is best practice to use containers that are marked properly for the fuel they contain. Labels are also recommended, especially for oils, as their characteristics and composition can vary.
