The United States Consumer Product Safety Commission is an independent agency of the United States government. The CPSC seeks to promote the safety of consumer products by addressing “unreasonable risks” of injury ; developing uniform safety standards ; and conducting research into product-related illness and injury. In part due to its small size, the CPSC attempts to coordinate with outside parties—including companies and consumer advocates—to leverage resources and expertise to achieve outcomes that advance consumer safety. The agency was created in 1972 through the Consumer Product Safety Act. The agency reports to Congress and the President; it is not part of any other department or agency in the federal government. The CPSC has five commissioners, who are nominated by the president and confirmed by the Senate for staggered seven-year terms. Historically, the commission was often run by three commissioners or fewer. Since 2009, however, the agency has generally been led by five commissioners, one of whom serves as chairman. The commissioners set policy for the CPSC. The CPSC is headquartered in Bethesda, Maryland.
