Fuel Can Safety


Staying one step ahead of OSHA; the best practices for safely transporting gasoline


By Tim Walton 

Gas cans. Every contractor and landscaper has them in their truck, on the trailer or at the shop. You fill ‘em up, toss them in and go.

But I bet you have never given much thought to which portable gas cans are being used for your landscaping or construction business.

You should. There are actually a few government entities that are interested in which gas cans you use and how you transport them.

Their interests vary from saving the environment to preventing you from packing around a veritable bomb.

Not using the proper gas cans can be a costly mistake both physically and financially.

Here’s what we figured out that will hopefully give you some insight into staying safe and legal, or should we say, citation free.


Here’s the short take on the legal aspect. Occupational Safety and Health Administration (OSHA) requires that a gas can be a closed container that with a maximum capacity of 5 gallons.

The can must have a flash-arresting screen and a spring-closing lid, and be able to safely relieve internal pressure. “Safety cans,” which meet OSHA requirements, are exempt from most states’ spill-proof container regulations.

A legal fuel can must be approved by a nationally recognized testing laboratory, such as United Laboratory (UL), to satisfy OSHA requirements. Interestingly, flash-arresting screens are not included in the UL listing. (Note: being “UL Classified” is not the same as “UL Listed.”)


The Department of Transportation (DOT) considers flammable and combustible liquids to be hazardous materials and subject to strict transport rules.

Kolpin gas cans work excellent for landscaper’s needs.

There is, however, an exemption for Materials of Trade (MOT), which excludes gasoline used “to support the operation or maintenance of a motor vehicle (including its auxiliary equipment) or to directly support a principal business of a private motor carrier such as landscaping, pest control, painting, plumbing or welding. 

Gasoline is a medium or lower hazard and therefore the maximum package is 8 gallons for liquids (which is higher than the OSHA requirement).

Packages of MOT must be leak proof, closed and secured in the vehicle against movement and damage. For gasoline, the packaging must be made of metal or plastic and meet OSHA or USDOT regulations.

When it comes to transporting fuel in a pickup or trailer, DOT doesn’t allow a gross weight of more than 440 pounds for all containers of gasoline. (Gasoline weights about 6.15 pounds per U.S. gallon.)

That equates to about a dozen 5-gallon gas cans, and all the containers must be marked clearly with “Gasoline” or “Gas.”


If you work in California or other like-minded environmental states where the California Air Resources Board (CARB) and Environmental Protection Agency (EPA) play a heavy policing role there are additional requirements for consumer and homeowner type gas cans that differ from OSHA safety cans and DOT safety cans.

CARB calls gas cans Portable Fuel Containers (PFC) with regulations intended to address spillage and evaporative emissions with the goal being to minimize such spillage and emissions with spill-proof spouts and auto-closing lids.

CARB specifies that containers must have identification marks on the container and spill-proof spout and be color coded for specific fuels: red for gasoline; yellow for diesel and blue for kerosene.

Currently, OSHA safety cans and DOT safety cans are exempt from CARB regulations.

Basic Gas Can Safety

Common sense should also be a key guide when it comes to transporting fuel.

For instance, never fill a gas can when it’s in the trunk of a vehicle or in the back of a pickup because fuel vapors tend to gather at the lowest point of enclosed areas. Gas vapors in the bilge of a boat or bed of a pickup tend to go boom when exposed to a spark or open flame.

 Always place the can on the ground and keep the nozzle in contact with the can during the entire filling process to avoid ignition of vapors from static electricity.

Another safety tip: Don’t over-fill. Leave room in the container for expansion of the gas.

Vapor volume will increase as temperatures rise, so leaving open space for that expansion is important. (That’s why gas containers with vented lids is an OSHA requirement.)

Loaded and Locked

When transporting any kind of hazardous liquid it’s import to protect the containers from movement and potential damage. Gas cans sliding into hedge trimmers, mowers, shovel blades, rakes and other tools can be a big problem. Lock gas cans down before a wheel moves.

If CARB, DOT and OSHA regs don’t affect your business, the military-style (MIL-Spec) metal and poly gas cans work great because they take external abuse well and their mounting brackets are stout.

Kolpin also makes some nice poly gas cans designed for ATV/UTV use that work just as well in applications in a service body or trailer. They have special mounts that hold them secure, yet provide quick release.

Another route is custom fabricating brackets or cages specific for your pickup or trailer and to the gas cans you use.
