You can typically put up to 20 litres of diesel in a standard metal fuel can. This limit is often mandated by safety regulations to ensure the safe handling and transport of fuel.
Understanding Fuel Can Capacity for Diesel
When it comes to portable fuel storage, especially for diesel, the capacity of the container is a critical factor governed by safety and practical considerations. Specifically, common regulations often stipulate that the maximum capacity for a metal container designed for fuel storage is 20 litres. This information is crucial for anyone looking to transport or store diesel safely.
Why 20 Litres? Safety and Practicality
The 20-litre maximum capacity for metal fuel containers is not arbitrary. It's a widely adopted standard based on several key factors:
- Weight Management: 20 litres of diesel weighs approximately 17 kilograms (roughly 37.5 pounds). This weight is generally considered manageable for an average adult to lift, carry, and pour without significant strain or risk of injury. Larger quantities would quickly become unwieldy.
- Fire Safety: In the event of a spill or fire, smaller quantities of fuel contained within a 20-litre can reduce the overall hazard. It limits the spread of fuel and the intensity of a potential blaze compared to larger volumes.
- Ease of Handling and Storage: A 20-litre can is compact enough to be secured properly in a vehicle's boot or on a truck bed. It also fits easily into typical storage spaces like garages or sheds, without requiring specialized lifting equipment.
- Legal Compliance: Many jurisdictions, across various countries, have established this 20-litre limit for portable fuel containers to ensure public safety and minimize environmental risks associated with fuel transport and storage.
Choosing the Right Can for Diesel
While the capacity is crucial, selecting the correct type of can for diesel is equally important. Always use a fuel-specific, certified container.
- Material: For diesel, robust metal containers (steel or aluminium) are highly recommended. They are durable, less prone to static electricity buildup (a fire risk), and comply with the 20-litre capacity standard. While plastic cans exist, they may have different specifications or be better suited for other liquids.
- Colour Coding: Although not universally mandated, diesel cans are often yellow, black, or blue. This helps distinguish them from gasoline cans, which are typically red.
- Certification: Look for stamps or labels indicating compliance with safety standards, such as UN (United Nations) markings, or specific national standards (e.g., ANSI/UL in the US, CSA in Canada, TÜV in Germany).
Practical Tips for Filling and Storing Diesel
Adhering to best practices when handling diesel in cans is vital for safety.
| Aspect | Recommendation |
|---|---|
| Filling | Always place the fuel can on the ground before filling to dissipate static electricity. Never fill it inside a vehicle or on carpet. |
| Fill Level | Do not fill the can completely to the brim. Leave approximately 5-10% empty space (known as "headroom") to allow for thermal expansion of the diesel, especially in warm weather. For a 20-litre can, this means filling it with around 18-19 litres. |
| Transport | Secure the can upright in a well-ventilated area of your vehicle. Prevent it from tipping, sliding, or rolling. Avoid transporting fuel inside the passenger compartment if possible. |
| Storage | Store the can in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, open flames, and ignition sources (e.g., water heaters, furnaces, electrical motors). Keep it out of reach of children and pets. |
| Maintenance | Regularly inspect the can for any signs of damage, corrosion, cracks, or leaks. Replace any damaged containers immediately. |
By following these guidelines and adhering to the 20-litre capacity limit for metal containers, you can safely and effectively transport and store diesel for your needs.
