The jerrycan, a ubiquitous symbol of fuel and utility, has transcended its military origins to become an essential tool for adventurers, homeowners, and even emergency response teams. But what exactly is a jerrycan, and how did this seemingly simple container become so widely adopted? This article delves into the history, design, and uses of the jerrycan, addressing some of the most common questions people search for online.
From Battlefield Necessity to Global Icon
The jerrycan’s story begins in 1930s Germany. With the rise of mechanized warfare, the German military needed a reliable and portable way to transport fuel for their growing fleet of tanks and vehicles. Existing containers were cumbersome, prone to leakage, and often made of flammable materials. In response, Germany’s Ministry of War commissioned a new design.
Engineer Johann Flick emerged with a revolutionary concept: a rectangular, stackable container made of pressed steel. This design offered several advantages. The steel was strong and durable, protecting the fuel from punctures and harsh environments. The rectangular shape allowed for efficient packing and storage, while the three handles (one on top and one on each side) made it easy to carry even when full. Perhaps most importantly, the jerrycan incorporated a clever spout with a self-closing mechanism, virtually eliminating the risk of spills or leaks.
The new container, initially called the Wehrmachtskanister (German Army Canister), proved to be a game-changer. Its efficiency and durability gave German forces a logistical advantage during the early years of World War II. Allied troops quickly recognized the jerrycan’s superiority and began capturing and using them themselves. The name “jerrycan” likely originated as a colloquial term used by Allied soldiers, possibly derived from the slang term “jerry” for anything German.
After the war, the jerrycan’s design became public domain, and its production spread worldwide. Manufacturers began offering variants in different sizes and materials, with high-density polyethylene (HDPE) becoming a popular choice due to its lighter weight and resistance to corrosion. Today, jerrycans are available in a wide range of sizes, typically from 5 liters to 20 liters, catering to various needs.
Beyond Fuel: The Versatility of the Jerrycan
While fuel transportation remains a primary use for jerrycans, their usefulness extends far beyond gasoline and diesel. Here’s a glimpse into the diverse applications of the jerrycan:
Water Storage: Jerrycans are excellent for storing and transporting clean water. They are ideal for camping trips, emergency preparedness kits, and situations where access to clean water is limited.
Chemical Transportation: Specially designed jerrycans made from HDPE are suitable for storing and transporting various chemicals, including oil, lubricants, and antifreeze. These containers often come with specific labeling and certifications to ensure safe handling.
Emergency Response: Emergency response teams rely on jerrycans to transport water, fuel, and other essential supplies to disaster zones. The durability and portability of jerrycans make them invaluable in such situations.
Off-Road Adventures: Off-road enthusiasts use jerrycans to carry extra fuel for their vehicles, allowing them to explore remote areas without worrying about running out of gas.
Home Use: Homeowners use jerrycans for various purposes, such as storing rainwater for gardening, transporting kerosene for heaters, or holding emergency supplies like gasoline for generators.
Safety First: Important Considerations When Using Jerrycans
The contents of a jerrycan can pose safety hazards if not handled properly. Here are some key points to remember:
Always use jerrycans designed for the specific liquid you are storing. Not all jerrycans are created equal. Ensure the material and design are appropriate for the intended content.
Never store flammable liquids near heat sources or open flames. The vapors from gasoline and other fuels can easily ignite, posing a serious fire risk.
Label your jerrycans clearly. This helps identify the contents quickly and avoid accidental misuse.
Transport jerrycans securely. Ensure they are properly fastened in your vehicle to prevent spills or leaks during transport.
Dispose of empty jerrycans responsibly. Do not simply throw them away. Many recycling centers accept HDPE jerrycans.
Never reuse jerrycans that have held hazardous chemicals. Residues can linger and contaminate future contents.
FAQ’S
What is a jerrycan?
A jerrycan is a portable, leak-proof container typically made of high-density polyethylene (HDPE) plastic or galvanized steel. Its rectangular shape with a tapered top and flat bottom makes it easy to stack and transport. Jerrycans come in various sizes, with the most common being 5 liters (around 1.3 gallons) and 20 liters (around 5.3 gallons).
Where does the name “jerrycan” come from?
The name “jerrycan” is derived from the German word “Jerrican,” which itself is believed to be a wartime adaptation of the proper noun “Gerry,” a shortening of “Germane.” The origin story reflects the jerrycan’s development during World War II by the German military for transporting fuel.
What can you store in a jerrycan?
Jerrycans are ideal for storing and transporting a variety of liquids, including:
Fuel: Gasoline, diesel, and kerosene are commonly stored in jerrycans. However, it’s crucial to use cans specifically designed for fuel, as they often have flame arrestors and are made with materials that prevent leaks and static build-up.
Water: Jerrycans are a popular choice for storing drinking water, especially for emergencies or outdoor activities. Opt for food-grade plastic jerrycans for safe water storage.
Other liquids: Depending on the jerrycan’s material and certifications, you can also store non-flammable liquids like oil, antifreeze, or even some chemicals (always check the manufacturer’s recommendations).
What are the different types of jerrycans?
There are two main types of jerrycans:
Plastic jerrycans: These are the most common and affordable option. They are lightweight, resistant to rust and corrosion, and come in various translucent or opaque colors. However, they may not be suitable for storing highly volatile liquids or for long-term fuel storage, as some plastics can degrade over time.
Metal jerrycans: Traditionally made of galvanized steel, these jerrycans offer superior durability and are ideal for long-term fuel storage. They are also more resistant to punctures and extreme temperatures. However, they are heavier and more expensive than plastic options.
What are some safety precautions to take when using jerrycans?
Safety is paramount when handling jerrycans. Here are some key points to remember:
Always use the jerrycan for its intended purpose. Don’t store food or beverages in a jerrycan previously used for fuel or chemicals.
Never store a jerrycan near open flames or heat sources.
Open and close jerrycans carefully to avoid spills. Ensure the cap and spout are secure when not in use.
Vent pressure buildup before refueling. Most jerrycans have a small spout on the side for this purpose.
Label your jerrycans clearly. This is especially important if you’re storing multiple liquids.
Dispose of empty jerrycans responsibly. Check with your local authorities for proper disposal guidelines.
Can you transport jerrycans in your car?
Yes, you can transport jerrycans in your car, but there are regulations to follow. These regulations can vary depending on your location, so it’s best to check with your local authorities. Generally, you’ll need to:
Secure the jerrycans properly to prevent them from tipping over or rolling around.
Ensure the jerrycans are upright and not leaking.
Transport only the amount of fuel you legally can (usually limited quantities).
Where can I buy a jerrycan?
Jerrycans can be purchased from various retailers, including hardware stores, automotive stores, online marketplaces, and camping/outdoor gear stores. Prices will vary depending on the size, material, and brand of the jerrycan.
Are there any interesting facts about jerrycans?
The jerrycan’s design is so iconic and functional that it has remained virtually unchanged since its World War II origins.
Jerrycans have played a significant role in humanitarian efforts, delivering clean water to remote areas and providing emergency fuel supplies during disasters.
The jerrycan’s durability is legendary. Stories abound of jerrycans surviving explosions, fires, and even being buried for decades before being unearthed in perfectly usable condition.
