Which of the following agencies requires strict labeling on chemicals by the manufacturer?

The agency that requires strict labeling on chemicals by the manufacturer is the Environmental Protection Agency (EPA). The EPA focuses on protecting human health and the environment, which includes regulating the use and labeling of toxic chemicals. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the EPA mandates that pesticides and certain chemicals must have labels that provide information about safe handling, usage instructions, and potential hazards. This ensures not only compliance with safety standards but also helps in preventing accidental exposure to harmful substances.

In contrast, while the other agencies play crucial roles in public health and safety, they focus on different aspects. The Centers for Disease Control and Prevention (CDC) primarily deals with disease prevention and control rather than chemical labeling. The Food and Drug Administration (FDA) regulates food, drugs, and medical devices, focusing on their safety and efficacy rather than on labeling chemicals directly. The Occupational Safety and Health Administration (OSHA) oversees workplace safety and health standards, which include the Hazard Communication Standard that requires labeling; however, sourcing strict labeling directly falls under the jurisdiction of the EPA for chemicals specifically.
