Which of the following organizations regulates laboratory chemical hazards and exposure

The Drug Enforcement Administration (DEA) primarily focuses on controlling and regulating the distribution and use of narcotics and other controlled substances. While it may intersect with laboratory practices regarding controlled substances, it does not oversee general chemical hazards or exposure regulations in laboratories.

The Food and Drug Administration (FDA) regulates food safety, pharmaceuticals, and medical devices, but its focus is not on workplace safety or chemical hazards in laboratories. While the FDA may impose regulations on products that could be tested in laboratories, it does not specifically regulate laboratory working conditions related to chemical exposure.

The Clinical Laboratory Improvement Amendments (CLIA) regulate laboratory testing and laboratory quality assurance, primarily in clinical settings. However, CLIA does not address chemical hazards or exposure regulations that apply broadly across laboratory environments.
