Hazmat question
What is Appendix A of the hazmat table?
Appendix A to §172.101 is the Reportable Quantity (RQ) list — a separate supplement to the main Hazardous Materials Table. While the main table covers shipping classification (hazard class, UN number, packing group), Appendix A answers a narrower question: how much of a specific substance can be released before it has to be reported to the National Response Center.
