CPSC Requires Lifesaving Flame Mitigation Devices on Gas Cans and Other Portable Fuel Containers

Release Date: January 17, 2023

WASHINGTON, D.C. –The U.S. Consumer Product Safety Commission (CPSC) is making gas cans and other fuel containers safer by requiring flame mitigation devices. The new mandatory safety standard will go into effect in July 2023. Congress required the agency to put rules into place to protect consumers under the Portable Fuel Container Safety Act (PFCSA) of 2020.

Each year, thousands of people go to emergency departments with burn injuries related to flammable liquids. Many burn incidents involve liquid fuel used on a backyard fire pit, a campfire, a bonfire or burning trash. Vapors from these liquids are invisible and dangerous. 

Flame mitigation devices, such as flame arrestors, protect against flame jetting and container rupturing. Flame jetting is a phenomenon where an external ignition source – such as an open flame – causes a sudden ignition of fuel within a container and forcefully expels burning vapor and liquid from the mouth of the container, resulting in a blowtorch-like effect. Container rupturing is like flame jetting, except the burning vapor and liquid are expelled through a rupture in the container.

Flame mitigation devices will be required on new gas cans and other containers that are sold empty, such as for kerosene and diesel, and on new containers that are sold pre-filled with fuels such as charcoal lighter fluid, liquid fireplace fuels and pre-mixed gasoline and engine fuel. Most fuel containers already have the safety device.

By a 4-0 vote, the CPSC made mandatory three existing voluntary standards:

  • ASTM F3326-21, Standard Specification for Flame Mitigation Devices on Portable Fuel Containers;
  • ANSI/CAN/UL/ULC 30:2022, Standard for Safety Metallic and Nonmetallic Safety Cans for Flammable and Combustible Liquids and;
  • ASTM F3429/F3429M-20, Standard Specification for Performance of Flame Mitigation Devices Installed in Disposable and Pre-Filled Flammable Liquid Containers.

In December 2022, the Commission also voted to update child resistance requirements for closures on portable gas cans, and diesel and kerosene containers. These requirements became effective on December 22, 2022. The revisions update the existing standard to reflect current gasoline container designs, remove ambiguities in the child test requirements, and create an adult test that reflects usage patterns. The revisions also apply requirements to aftermarket products such as pour spouts.

About the U.S. CPSC
The U.S. Consumer Product Safety Commission (CPSC) is charged with protecting the public from unreasonable risk of injury or death associated with the use of thousands of types of consumer products. Deaths, injuries, and property damage from consumer product-related incidents cost the nation more than $1 trillion annually. CPSC's work to ensure the safety of consumer products has contributed to a decline in the rate of injuries associated with consumer products over the past 50 years. 

Federal law prohibits any person from selling products subject to a Commission ordered recall or a voluntary recall undertaken in consultation with the CPSC.
