Portable fuel tank safety

Portable fuel tanks are a convenient option for many, but they can pose serious safety risks if not handled properly. Here are some important safety tips to follow when using and storing portable fuel tanks:

Ventilation and Fumes

It is crucial to ensure proper ventilation when using portable fuel tanks. Fuel tanks should never be placed in enclosed spaces without adequate ventilation. Fuel fumes can accumulate and lead to a risk of ignition or explosion. If a portable fuel tank must be used in an enclosed area, it is recommended to install a blower system or provide external ventilation by venting to the outside.

Distance and Separation

Portable fuel tanks should be kept at a safe distance from buildings and other flammable materials. The recommended distance is a minimum of 20 feet away from any structure. Additionally, when grouping multiple portable fuel tanks together, ensure a clear separation of at least 5 feet between tanks, especially if the combined capacity exceeds 2,200 gallons.

Approved Containers and Fuel Type

Only approved containers and portable fuel tanks specifically designed for the type of fuel in use should be utilized. Plastic containers are generally discouraged as they often do not meet the safety requirements for storing flammable liquids. Always use containers that comply with the latest standards and regulations, such as the Portable Fuel Container Safety Act (PFCSA) and its associated voluntary standards.

Spark and Heat Sources

Avoid any potential spark or heat sources near portable fuel tanks. When refuelling, always place the tank on the ground and keep it away from vehicles to prevent static electricity build-up, which can lead to sparks and explosions. Keep portable fuel tanks protected from heat radiating from engines or exhaust systems.

Signage and Identification

Proper signage and identification are crucial for portable fuel tanks. Display conspicuous contents stickers indicating the type of fuel ("Diesel Fuel", "Kerosene", etc.) and large National Fire Protection Association (NFPA) diamond placards so that emergency personnel can quickly identify flammable materials from a distance.

By following these safety guidelines and staying informed about regulatory requirements, users can help minimize the risks associated with portable fuel tanks and ensure a safer environment for themselves and others.

How to fill a portable fuel tank

Filling a portable fuel tank can be a tricky process, but there are some best practices to follow to ensure safety and efficiency. Here is a step-by-step guide on how to fill a portable fuel tank:

Prepare the Tank and Work Area:

Before filling, it is essential to place the portable fuel tank on the ground in a well-ventilated area. Avoid filling the tank inside a vehicle or boat, as static electricity can build up and cause a spark, leading to a potential explosion. Ensure that the tank is stable and secure to prevent accidental spills.

Use the Correct Equipment:

Utilize a suitable fuel nozzle designed for portable fuel tanks. Ensure that the nozzle fits securely onto the tank's filling port. If you're using a fuel pump, choose one that is compatible with the type of fuel and that has an automatic shut-off mechanism to prevent overfilling.

Fill the Tank Safely:

When filling the tank, maintain contact between the nozzle and the tank. This practice helps dissipate any static electricity buildup. It is also important not to overfill the tank, as gasoline expands and contracts with temperature changes. Leave some space in the tank to accommodate these fluctuations and prevent spills.

Monitor the Filling Process:

Pay close attention to the filling process. Some modern tanks have features like vent whistles or fuel flow meters that indicate when the tank is full. If your tank does not have these features, use a logbook to track hours of fuel consumption and refuelling intervals. Always follow safety guidelines, such as allowing sufficient time for ventilation after fuelling.

Handle Fuel Spills and Ventilation:

In the event of a fuel spill, ensure that the area is well-ventilated to prevent the buildup of flammable vapours. Gasoline vapours are heavier than air and tend to settle in low-lying areas. If your boat or vehicle has an installed blower, use it as per the manufacturer's recommendations after fuelling.

By following these steps and staying vigilant, you can safely and effectively fill a portable fuel tank. Remember always to prioritize safety and adhere to local regulations and guidelines when handling flammable liquids.

How to store a portable fuel tank

When storing a portable fuel tank, there are several important safety precautions to keep in mind. Firstly, ensure that the tank is stored outdoors in a well-ventilated area. Storing the tank in a closed space can allow fuel vapours to escape and concentrate, creating a risk of ignition from a spark. Keep the tank in a flat, level, outdoor area that is out of direct sunlight and away from other flammable materials. Maintain a distance of at least 10 feet between the tank and any flammable items.

It is also crucial to keep the portable fuel tank upright and secure during storage. Use ropes or straps to stabilise the tank and prevent it from sliding or tipping over. If possible, avoid using chains or similar materials that could damage the tank's surface. Additionally, always place the tank on the ground when filling it and ensure that the gas pump nozzle remains in contact with the tank during the filling process. Never fill a portable tank while it is inside a vehicle, as static electricity can build up and cause a spark, leading to a potential explosion.

To ensure the safety of the surrounding area, it is recommended to use only approved containers for your portable fuel tank and to maintain a consistent colour-coding scheme for different types of fuel. For example, the standard colour code is blue for kerosene, red for gasoline, and yellow for diesel fuel. Mixing up containers or introducing the wrong type of fuel into a tank can have dangerous consequences. Regularly rotate your fuel cans to ensure that you always have reasonably fresh fuel on hand.

Lastly, always follow basic safety guidelines when handling portable fuel tanks. Prohibit smoking or carrying smoking materials within a safe distance of the fuel tank, and ensure that any electrical fixtures are "explosion-proof" and properly sealed to prevent sparks. Clean up any spills promptly and only use equipment that is approved for the specific type of fuel you are handling. By adhering to these guidelines, you can safely store and utilise your portable fuel tank.
