Which organization regulates chemical security in the U.S.?

The Chemical Facility Anti-Terrorism Standards (CFATS) is the correct answer because it specifically focuses on the security of chemicals within the United States. CFATS is a regulatory program administered by the Department of Homeland Security (DHS) that requires facilities that possess certain chemicals to develop security plans to reduce the risk of terrorist attacks. These standards are critically important for enhancing security measures around high-risk chemicals and ensuring that facilities are prepared to prevent and mitigate potential chemical security threats.

The other organizations mentioned have important roles, but they do not primarily focus on chemical security. The Environmental Protection Agency (EPA) is primarily concerned with protecting human health and the environment through regulations on hazardous waste and pollution, while the Occupational Safety and Health Administration (OSHA) focuses on ensuring safe and healthy working conditions for employees across various industries, rather than security from chemical threats. The National Institutes of Health (NIH) primarily conducts and supports medical research and is not involved in regulatory aspects of chemical security. Therefore, CFATS is the most relevant organization when it comes to regulating chemical security in the U.S.
