The Children's Gasoline Burn Prevention Act (CGBPA or the Act) adopted as a consumer product safety rule, the child-resistance requirements for closures on portable gasoline containers published in the ASTM voluntary standard, Standard Specification for Determination of Child Resistance of Portable Fuel Containers for Consumer Use, ASTM F2517-05. ASTM F2517 was revised in 2015. These revisions became law under the Act, which the Commission codified through a direct final rule in 2015. On November 13, 2017, the Commission received notice from ASTM that a revision to ASTM F2517 was published in November 2017. In this direct final rule the Commission reviews and evaluates the revised ASTM F2517, finding that the revisions carry out the purposes of the CGBPA's requirements. Accordingly, the 2017 revisions to the child- resistance requirements will be automatically incorporated and apply as the statutorily mandated standard for closures on portable gasoline containers. This direct final rule updates the Commission's regulation to reflect that the requirements for closures on portable gasoline containers must meet the requirements in ASTM F2517-17.
