Which organization requires knowledge of safe handling, mixing, storing, and disposal of pesticides?

The Environmental Protection Agency (EPA) is the correct choice because it is the federal agency responsible for regulating the use of pesticides to ensure they are handled safely and effectively. The EPA sets guidelines and standards for the safe handling, mixing, storage, and disposal of pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). This includes establishing safety protocols and providing training resources to minimize risks to human health and the environment during pesticide application and management.

While other organizations like the Department of Agriculture may provide local implementation guidance or regulations regarding agriculture and pesticide use, the EPA specifically focuses on national standards and safety measures associated with pesticide chemicals. The Chemical Safety Board and OSHA are concerned with chemical safety and workplace health regulations, but they do not specifically regulate pesticide usage in the same way the EPA does.
