The U.S. Consumer Product Safety Commission (CPSC) has issued a notice of proposed rulemaking under the Consumer Product Safety Improvement Act of 2008 to establish a mandatory safety standard for frame child carriers. Defining a frame child carrier as “a product normally of sewn fabric construction on a tubular metal or other frame, which is designed to carry a child, in an upright position, on the back of the caregiver,” the agency has determined that the voluntary standard on which the proposal is based—ASTM F2549-14, Standard Consumer Safety Specification for Frame Child Carriers—is sufficient to address the hazards it has identified, but has proposed one modification “to specify requirements for the retention system performance test to provide clear pass/fail criteria for the carrier’s restraints.” CPSC also proposes amending 16 C.F.R. Part 1112 to add frame child carriers to the list of children’s product safety rules for which CPSC has issued a notice of requirements. Comments will be accepted until July 30, 2014.
