Using gas equipment requires buying, maintaining, and storing gasoline. When done in small quantities, this involves some type of portable fuel container (PFC), or gas can. A gas can is a container designed to safely store liquid fuel. It's mandated by law in some areas and subject to design regulations by the Environmental Protection Agency (EPA). Though using a gas can is simple in theory, there are many things that go into using one safely and effectively.
The spout is the piece that dispenses and funnels the gas from the container into a machine’s gas tank. It’s also where gas is likely to leak or spill. In 2009, the EPA began requiring all gas cans to adhere to a series of regulations. All gas cans manufactured and sold in the United States must:
These regulations aim to enhance safety, prevent spills, and reduce environmental damage. Today, gas cans and their spouts vary in design, but are all manufactured to adhere to EPA regulations. Gas cans manufactured and sold prior to January 1, 2009 remain legal to use; however, newer designs are strongly recommended.
When filling a gas can, remember that gas is volatile and easy to ignite. Take all necessary precautions to keep the gas can away from flames, vehicles, and people. Make sure that all static electricity is discharged prior to filling.
When cleaning a gas can, first make sure that it’s completely empty of gasoline. If it is not empty, then safely dispose of the gas according to local or state regulations. After cleaning, it is imperative that no water is left in the can. If need be, rinse out with gas after cleaning and before using the can for storage.
If the interior of the can requires more heavy-duty cleaning, try using a bent brush or even a chain. Both can help loosen and scrape off debris, as can gravel or aquarium rock. Just make sure to remove it completely before filling the can with gas.
Gas cans present dangers directly related to flammability, so proper storage is imperative. The length of storage can also affect the integrity of the gas, rendering it ineffective after long-term storage. Make sure to pay attention to how gas cans are stored and for how long. Follow all recommended guidelines.
Remember that gas is extremely flammable and expands with heat. When storing a can of gas, keep it somewhere cool, dry, and well-ventilated. Recommended storage locations include sheds, detached garages, and other out-buildings.
Storing gas in a utility room, basement, or attached garage puts the entire business or house in danger if the fuel catches fire. These areas also often include a furnace and other electrical equipment that can serve as an ignition source.
Storing gas cans outdoors is genereally not recommended, unless housed in an out-building or shed. The location must be cool, dry, and shielded from direct sunlight.
Spill-proof gas cans are designed to help conserve gasoline and increase safety. Multiple designs are available on the market, ranging from spouts that twist open to those with buttons to control pouring.
One particular design uses a spring mechanism that allows gas to pour only when the button is depressed and pushed backwards. If pressure is lifted from the button, the spring pushes it forward and stops the flow of gasoline.
Red Gas Can
Use a red gas can for gasoline. It is perhaps the most commonly seen color, but should not be used as a "universal" color for just any fuel type.
Blue Gas Can
Use a blue gas can for kerosene. Though flammable, kerosene is less flammable and volatile than either gasoline or diesel fuel.
Yellow Gas Can
Use a yellow gas can for diesel fuel. It should never be used to store any other liquid fuel.
