Which Appendix Section lists self-reactive substances from Division 4.1 and organic peroxides from Division 5.2?

• A. Appendix B Nomenclature
• B. Appendix C Currently Assigned Substances
• C. Appendix D Competent Authorities
• D. Appendix E Packaging Test Facilities, Manufacturers and Suppliers

Answer: (A)

Appendix B Nomenclature is where the official names and identifiers for dangerous goods are listed, with cross-references for the substances defined in the DGR. Self-reactive substances from Division 4.1 and organic peroxides from Division 5.2 appear there because the nomenclature provides standardized terms, UN numbers, and classification details needed for consistent labeling and transport. The other appendices serve different roles—Appendix C covers substances currently assigned to classifications, Appendix D lists competent authorities, and Appendix E provides details on packaging test facilities, manufacturers, and suppliers.
