Where can the OSHA definition of a hazardous substance be found?

The correct answer highlights the connection between the legal definitions of hazardous substances in environmental regulations. Specifically, 40 CFR 261.3 provides criteria for identifying hazardous waste, which is crucial for understanding what materials are regulated under the Resource Conservation and Recovery Act (RCRA). Meanwhile, Section 101(14) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) defines hazardous substances to facilitate the cleanup of contaminated sites.

These two references are essential because they establish comprehensive legal frameworks regarding the management and disposal of hazardous materials. Understanding these definitions is vital for professionals working in hazardous waste operations, as they need to know what substances are classified as hazardous to ensure compliance with safety standards and proper waste management practices. The relationship between these definitions is important for the effective regulation of hazardous substances in various contexts, particularly for emergency response efforts and cleanup operations.
