Which two regulations define hazardous waste according to OSHA?

The definition of hazardous waste according to OSHA is outlined in specific regulations, primarily through guidance from the Resource Conservation and Recovery Act (RCRA). The regulation 40 CFR 261.3 details the criteria for identifying which wastes are considered hazardous. This regulation establishes the characteristics of hazardous waste, such as ignitability, corrosivity, reactivity, and toxicity.

The inclusion of 49 CFR 171.8 alongside 40 CFR 261.3 provides additional context, as it relates to the definition of hazardous materials in the context of transportation. This regulation is relevant because it aligns with the broader understanding of hazardous materials and complements how hazardous waste is managed, especially when it is in transit.

Therefore, the explanation of hazardous waste as defined by OSHA primarily hinges on the criteria set forth in 40 CFR 261.3 and pertains to how hazardous materials are classified and regulated during transportation as specified in 49 CFR 171.8. This comprehensive approach is essential for ensuring safety and compliance in hazardous waste operations, as it lays the groundwork for proper handling, storage, and transportation of hazardous waste materials.
