Which agency is responsible for regulating the use of explosives in the United States?

The agency responsible for regulating the use of explosives in the United States is the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). The ATF is tasked with enforcing federal laws related to explosives and ensuring compliance with safety regulations. This includes the licensing of individuals and businesses that manufacture, import, or deal with explosives. The ATF also manages the legal framework surrounding explosives storage, transportation, and use, providing guidelines and enforcement to prevent accidents and unlawful activities.

The other agencies mentioned have different focuses and regulatory scopes. For example, the Environmental Protection Agency (EPA) primarily addresses environmental issues, including pollution control and hazardous waste management. The Occupational Safety and Health Administration (OSHA) is dedicated to ensuring worker safety in various industries but does not specifically regulate explosives themselves. The Federal Bureau of Investigation (FBI) concentrates on national security and law enforcement issues, particularly concerning criminal activities and terrorism but does not handle explosives regulation. Thus, the ATF is the designated agency for explosives oversight, making it the correct choice.
