Which federal agency has regulations that include approved timers for tanning units?

The correct answer is the FDA, which is the U.S. Food and Drug Administration. The FDA is responsible for regulating various products, including tanning devices. One of the critical aspects of their regulation involves ensuring the safety and efficacy of tanning units, which includes the approval of timers used on these devices. Timers are essential for restricting exposure time to UV radiation, helping to minimize the risk of overexposure and potential health hazards such as skin damage and increased cancer risk.

In contrast, Health Canada serves a similar regulatory function in Canada but is not involved in U.S. federal regulations regarding tanning equipment. The FTC, or Federal Trade Commission, primarily focuses on consumer protection and preventing deceptive practices in marketing, rather than on safety standards for tanning units. The Competition Bureau Canada also deals with business practices and competition law, rather than product safety and regulations associated with tanning devices. Thus, the FDA is the agency explicitly tasked with establishing regulations that include the approval of timers for tanning units in the United States.
