5 Best Metal Gas Cans

The Buyer’s Guide

Understanding Safety Cans

Before we get into the nitty-gritty of safety cans, let’s first understand what they are and why you need one. There is a complete guide to understanding the differences between types of flammable liquid storage containers.

What Is Safety Can

A safety can is a portable container specifically designed to store and dispense flammable liquids. Safety cans are made of steel and have a double-wall construction with a pressure relief valve. The valves allow the contents of the can to be dispensed without opening the lid, which reduces the risk of fire or explosion.[8]

Gas Can Color Codes

There are four colors that are most commonly used for safety cans: red, yellow, blue, and green.

Of course, these are not the only color options available – you can find safety cans in just about any color imaginable. However, the four colors mentioned above are the most commonly used because they help to quickly identify what type of flammable liquid is inside.

When choosing a safety can, it’s important to select one that has a color that will be easily visible in your work area. This will help to ensure that everyone knows which type of flammable liquid is inside and can take the appropriate precautions.

Safety Can Materials

The most common type of safety can is made from galvanized steel, which is then coated with a layer of zinc. This makes the can rust-resistant and durable, able to withstand years of use.

There are also stainless steel safety cans available, which offer even more protection against corrosion and rust. However, these cans are often more expensive than their galvanized counterparts.

Finally, there are plastic safety cans available on the market. These are typically made from high-density polyethylene (HDPE), and they offer a number of benefits over metal cans. For one, they’re lighter in weight, making them easier to transport. They’re also less likely to dent or corrode over time. However, they’re not as fire-resistant as metal cans, so they may not be the best choice for storing flammable liquids.

Type I & Type II Safety Cans

There are two different types of safety cans available on the market: Type I and Type II. Here’s a quick overview of each type:

Type I Safety Cans are designed for storing and dispensing flammable liquids, such as gasoline or kerosene. They have a self-closing lid that opens automatically when the spout is depressed, and they’re equipped with a pressure-relief valve to prevent dangerous buildups of pressure inside the can.

Type II Safety Cans are designed for storing and dispensing both flammable and combustible liquids, such as paint thinners or solvents. They have a double-wall construction that helps to prevent heat transfer in the event of a fire, and they’re equipped with a spring-loaded release valve that opens to release pressure in the event of a fire.[7]

The Parts That Define a Type I Can

The most defining characteristic of a Type I can is its self-closing lid. A spring-loaded mechanism forces the lid shut as soon as the user takes their hand off the spout, making it impossible to accidentally leave the can open. This is important because it prevents vapors from escaping, which could lead to a fire or explosion if they came into contact with an ignition source.

Another defining feature of a Type I can is its pressure-relief valve. This valve is designed to release built-up pressure inside the can, preventing it from becoming a dangerous bomb in case of a fire.

Type I cans also have an extra layer of protection against static electricity. A metal screen covers the opening of the can, which prevents sparks from entering and igniting the contents.

Finally, all Type I cans are made of welded steel construction for durability and to prevent leaks.

The Parts That Define a Type II Can

Type II cans have a few defining features that make them different from other types of safety cans. For one, they have a self-closing lid. This is a big safety feature because it means that the can won’t accidentally spill its contents. The lid also has a pressure-relief valve to prevent the build-up of pressure inside the can. Finally, Type II cans are made from double-walled construction with a fire-resistant barrier in between the walls. This makes them much more resistant to heat and flames than other types of safety cans.

There are two main types of Type II safety cans: steel and aluminum. Steel cans are generally more durable and heavier duty than aluminum ones. However, they’re also more expensive. Aluminum cans are lighter and usually cost less, but they’re not as durable.

Components Of Safety Can

One of the most important things before purchasing or using a safety can is to understand its components. This will help you in not only identifying a good quality product but also aid you in maintaining it for the long term.

• All safety cans have three basic parts: the body, the lid, and the spout.
• The can’s body is where the flammable liquid is stored. It’s usually made of galvanized steel that has been coated with red paint to identify it as a flammable liquid container.
• The lid is used to cover the opening of the can and has a spring-loaded mechanism that automatically closes the lid when released.
• The spout is where you pour the flammable liquid out of the can. It’s usually made of brass or stainless steel and has a screen to filter out any debris.

There are also some safety cans that come with an additional feature, which is a pressure relief valve. This valve is used to release any build-up of pressure inside the can, preventing it from exploding.

Now that you know the components of a safety can, let’s look more closely at their features.

Spring-loaded or Self-Closing Cap

The next thing to consider when choosing a safety can is the type of closure. Spring-loaded, or self-closing, caps are going to be your best bet. These closures are designed to automatically close and seal the opening of the can if it’s tipped over. This is an important safety feature because it prevents flammable liquids from spilling out and igniting.

There are two main types of spring-loaded closures: push button and lever operated. Push button closures are the most common type. They’re easy to use and can be opened with one hand. Lever operated closures are a little more expensive, but they’re also easier to open and close.

Positive Pressure Release Valve

One of the most important features of a safety can is the positive pressure release valve. This valve is designed to automatically release any pressure that builds up inside the can, preventing it from exploding.[9]
Most safety cans will have this valve located near the top, so that any pressure is released before it has a chance to build up too much. However, some models may have the valve located on the side or bottom of the can.

If you are unsure where the valve is located on your particular model, be sure to consult the manufacturer’s instructions before using it.

It is also important to note that not all safety cans are equipped with this type of valve. If yours does not have one, you will need to be especially careful to avoid overfilling it, as this can cause the pressure to build up and potentially cause the can to explode.

If you are looking for a safe and effective way to store flammable liquids, a safety can is an excellent option. Be sure to choose one that is equipped with a positive pressure release valve to help prevent any accidents.

Flame Arrestor

Most safety cans have a flame arrestor in the spout. This is a small metal mesh screen that prevents any sparks or flames from entering the can. The arrestor also keeps out dirt and debris.

When using a safety can, always make sure the flame arrestor is in place and in good condition. A damaged or missing arrestor can allow dangerous fumes to escape from the can.

If you’re using a gas-powered engine near your safety can, be sure to shut off the engine before you start fueling. And always keep a fire extinguisher nearby, just in case.

Raised Bottom

Most safety cans have a raised bottom that keeps the can slightly elevated off the ground. This is important because it allows any liquids inside the can to flow towards the spout, making it easier to pour. It also prevents the can from tipping over and spilling its contents. Most safety cans also have a venting system that releases pressure build-up and prevents the can from exploding.

When choosing a safety can, make sure to select one that has both a raised bottom and a venting system. These two features are essential for preventing accidents and ensuring the safety of your flammable liquids.

Reinforcing Ribs

All metal safety cans have reinforcing ribs and beading to give the can body extra strength, making it resistant to denting and crushing. The beading also protects the can from corrosion by providing a physical barrier between the steel and any liquids that may come into contact with it.

Handle

Most safety cans have two handles – a carrying handle and a pouring spout.

The carrying handle is used to pick up and move the can when it is empty.

The pouring spout is used to control the flow of liquid when you are filling or emptying the can.

Some safety cans have a single handle that serves both purposes.

This type of handle is usually found on smaller cans, such as those that hold one gallon or less.

Both types of handles should be made from a material that will not conduct electricity, such as plastic or stainless steel.

Powder-Coat Finish

One feature to look for in a safety can is a powder-coat finish. This type of finish helps to protect the can from corrosion and also makes it easier to clean. A powder-coat finish will also give the can a long lasting, professional appearance.

Warning/Liquid Identification Label

All safety cans should have a prominent warning or liquid identification label. The label should be easy to read and understand, even in low light conditions. It should also be durable, so it doesn’t fade or peel over time.

There are two main types of labels: those that are printed directly on the can, and those that are affixed with adhesive. Printed labels are generally more durable, but they can be more difficult to read if they’re not placed in a conspicuous location. Adhesive labels, on the other hand, can be easily removed and replaced if they become damaged or unreadable.

Once you’ve selected the appropriate label for your needs, be sure to properly affix it to the can. If the label is not placed in a visible location, it may as well not be there at all.

In addition to a warning or liquid identification label, all safety cans should also have an expiration date. This will let you know when the contents of the can need to be replaced. Most safety cans have a lifespan of five years, but this can vary depending on the type of material they’re made from and how they’re used.

Be sure to check the expiration date on your safety can before using it. If the contents have expired, they may not be effective at extinguishing a fire.

FAQ

Which is better: a plastic or metal gas can?

Plastic gas cans are often cheaper than metal ones, but they have some serious disadvantages. Plastic is not as durable as metal, so it can easily crack or break. If you’re using a plastic gas can to store flammable liquids, there’s a greater risk of the contents leaking out.

Metal gas cans are more expensive, but they’re also much more durable and less likely to leak. If you’re going to be storing flammable liquids for any length of time, it’s worth investing in a metal safety can.

What type of valve is a safety valve?

A safety valve is a type of valve that is used to release pressure from a system. It is usually designed to open at a predetermined pressure, and will close when the pressure drops below that point. Safety valves are used in a variety of applications, including in boilers, compressors, and other systems where there is a risk of overpressure.

What is another name for a safety valve?

A safety valve is also known as a pressure relief valve. This type of valve is used to release pressure from a system that has become too pressurized. Safety valves are commonly found in boilers, pressure vessels, and other types of equipment that contain fluids under high pressure.

What is the difference between a safety valve and a pressure relief valve?

A safety valve is designed to release pressure before it becomes too high, while a pressure relief valve is designed to relieve pressure that has already reached an unsafe level. Both types of valves are used to protect equipment from over-pressurization.

What are some common problems with safety valves?

Some common problems with safety valves include corrosion, fatigue, and wear. Corrosion can cause the valve to stick or fail to open properly. Fatigue can cause the valve to leak or fail to close properly. Wear can cause the valve to become less sensitive and more likely to fail.

Will a gas explode in the sun?

This is a common question with a simple answer: yes. Gasoline, kerosene, and other petroleum-based products are highly volatile, meaning they easily evaporate and turn into vapor at relatively low temperatures. When these vapors come in contact with an ignition source – like a spark from the sun hitting the can – they can cause a dangerous explosion.

To avoid this, always store your flammable liquids in a cool, dark place away from any potential ignition sources. If you must keep them in the sun for any reason, make sure the cans are stored in a well-ventilated area so the vapors can dissipate quickly. And of course, always be sure to read and follow all warnings and instructions on the labels.

What are FMD gas cans?

FM-D gas cans are specially designed containers that are used to store flammable liquids. They are made from high-quality materials and have a number of safety features that make them ideal for use in hazardous environments.

FM-D gas cans are available in a variety of sizes and shapes, and can be fitted with a number of different accessories to suit your specific needs.

Can flammable liquids be stored in plastic containers?

The short answer is no. Flammable liquids should never be stored in plastic containers because they are highly combustible and can easily catch fire. Plastic containers can also release harmful chemicals when they burn, which can be dangerous to your health.

Should gas cans be vented?

Yes, all gas cans should be vented to allow air to enter the can as fuel is used. This prevents a dangerous build-up of pressure that could cause the can to explode. Most gas cans have a small vent hole near the top, but it’s a good idea to check before using one.

There are two types of vents available for gas cans: passive and active. Passive vents are typically small holes that allow air to enter as fuel is used, while active vents have a mechanism that allows the user to open and close the vent as needed.

Active vents are generally considered to be safer, as they give the user more control over when air can enter the gas can. However, both types of vents serve the same purpose and are effective at preventing pressure build-up.

Do galvanized gas cans rust?

Yes, galvanized gas cans will eventually rust. The zinc coating on the outside of the can protects the steel from rusting for a while, but eventually the zinc will wear away and the steel underneath will start to rust. If you have a galvanized gas can that is starting to rust, you can try to remove the Rust with sandpaper or a wire brush. If the rust is really bad, you might need to replace the can.
