It is used in the plastics industry in the manufacture of polyvinyl chloride (PVC) to terminate the polymerization process.[2][3] It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.[4] References1. ^Acetone thiosemicarbazone, chemicalland21.com 2. ^{{US patent reference | number = 3637632 | y = 1972 | m = Jan | d = 25 | inventor = Traynor, Lee | title = Agents for shortstopping free radical polymerization of vinylidene monomers}} 3. ^Acetone thiosemicarbazone (ATSC) {{webarchive |url=https://web.archive.org/web/20120227155656/http://www.88chem.com/product-Other-Chemicals/23356/Acetone-thiosemicarbazone-ATSC-.html |date=February 27, 2012 }}, 88chem.com 4. ^{{Cite journal | publisher = Government Printing Office | title = 40 C.F.R.: Appendix A to Part 355—The List of Extremely Hazardous Substances and Their Threshold Planning Quantities | url = http://edocket.access.gpo.gov/cfr_2008/julqtr/pdf/40cfr355AppA.pdf | edition = July 1, 2008 | accessdate = October 29, 2011 | postscript=.}} 3 : Hydrazines|Thioureas|Thiosemicarbazone |
