HazmatTable Guide
What Are F, K and D Hazardous Waste Codes?
Appendix A includes waste-stream entries identified by D, F and K numbers in addition to individual chemical names.
Short answer
Appendix A includes waste-stream entries identified by D, F and K numbers in addition to individual chemical names.
Appendix A includes waste-stream entries identified by D, F and K numbers in addition to individual chemical names.
Why this matters
These codes can be much easier to search directly than long waste descriptions. The supplied Appendix A explicitly says the waste streams appear in numerical sequence and are referenced by the appropriate D, F or K numbers.
A better workflow
If you know the waste code, search it directly. Then review the full waste-stream description and RQ rather than relying only on the short code.
Check your material in HazmatTable
Search the table, compare the listed RQ, and see the source in seconds.
What HazmatTable helps with
- Search a chemical, synonym, waste code or radionuclide.
- See the listed RQ and units without scanning a long PDF.
- Preserve important Appendix A footnotes and source context.
- Compare an entered package quantity with the listed RQ.
- Continue into related shipping and classification guides.
Important: HazmatTable is a reference and workflow tool, not a legal certification of a shipment. The shipper must verify the current HMR and the actual material, quantity, packaging and mode.
