The Consumer Product Safety Improvement Act of 2008 ("CPSIA") authorizes the U.S. Consumer Product Safety Commission ("Commission," "CPSC," or "we") to specify, by rule, for any consumer product or class of consumer products, characteristics whose existence or absence shall be deemed a substantial product hazard under certain circumstances. We are issuing a final rule to determine that any hand-supported hair dryer without integral immersion protection presents a substantial product hazard.
