Your Ultimate Guide to Jerry Cans: Everything You Need to Know

Introduction

Whether you're a seasoned outdoor enthusiast or a prepper planning for emergencies, jerry cans are an essential piece of gear. These rugged containers are designed to safely store and transport fuel, water, or other liquids in challenging environments. In this comprehensive guide, we'll delve into everything you need to know about jerry cans, from their history and different types to proper usage and maintenance.

A Historical Perspective

The jerry can's origins can be traced back to the early days of World War II. In 1939, Germany's Wehrmacht needed a reliable and robust container to fuel its rapidly expanding motorized forces. The resulting design, known as the Kraftstoffkanister 20 Liter, featured a distinctive rectangular shape, a carrying handle, and a spout with a cap that could be opened and closed with one hand.

Types of Jerry Cans

Over the years, numerous variations of the original jerry can have emerged, each designed for specific purposes. Here are some of the most common types:

  • Metal Jerry Cans: Made of heavy-duty metal, these cans offer excellent durability and puncture resistance. They are commonly used for transporting and storing fuels, such as gasoline, diesel, and kerosene.
  • Plastic Jerry Cans: Lightweight and resistant to corrosion, plastic jerry cans are ideal for safely storing and transporting liquids other than fuels, such as water, chemicals, or food.
  • High-Density Polyethylene (HDPE) Jerry Cans: These cans are made of extremely durable and chemical-resistant polyethylene plastic. They are widely used in military and industrial applications due to their ability to withstand harsh conditions.
  • NATO-Approved Jerry Cans: Meeting strict NATO standards, these cans are designed to safely store and transport fuel in military operations. They feature specific dimensions, materials, and markings to ensure compatibility with military equipment.

Choosing the Right Jerry Can

The best jerry can for your needs depends on several factors, including:

  • Purpose: What liquids will you be storing or transporting?
  • Volume: How much liquid do you need to accommodate?
  • Material: Are you looking for durability, corrosion resistance, or a combination of both?

Proper Usage and Maintenance

  • Handling: Always lift jerry cans by the handle and never by the spout. Avoid dropping or mishandling them as it can damage the container or cause leaks.
  • Filling: Slowly fill jerry cans while leaving some headspace at the top to allow for expansion and prevent spills during transport.
  • Transport: Secure jerry cans properly in your vehicle to prevent them from shifting or falling over. Use tie-downs or straps if necessary.
  • Storage: Store jerry cans in a cool, dry place away from heat sources and direct sunlight. Keep them upright to prevent leaks and contamination.

Safety Precautions

  • Never use jerry cans for storing drinking water unless they are specifically designed for that purpose.
  • Do not mix different types of liquids in the same jerry can.
  • Dispose of used fuel or other liquids responsibly according to local regulations.
