Which agency is responsible for developing guidelines related to hazardous materials such as asbestos and lead?

The Environmental Protection Agency (EPA) is the agency responsible for developing guidelines and regulations related to hazardous materials, including asbestos and lead. The EPA's primary mission involves protecting human health and the environment, which encompasses managing and regulating toxic substances found in various materials.

For example, the EPA has established rules regarding the handling, removal, and disposal of asbestos to minimize exposure risks to the public, particularly in older buildings where asbestos might be present. Similarly, the EPA has set guidelines for lead, especially concerning lead-based paints and lead contamination in water, further safeguarding public health.

While other agencies such as OSHA focus on occupational safety and health regulations (including those that may pertain to hazardous materials in the workplace), the EPA’s broader scope includes environmental exposure and public safety, making it the correct choice for guidelines on hazardous materials like lead and asbestos.
