Ngo-Ephreli 30, 2024, i-United States Environmental Protection Agency (EPA) yakhipha umthetho wokuvinjelwa kokusetshenziswa kwe-dichloromethane enezinhloso eziningi ngokuhambisana nemithethonqubo yokuphathwa kwezingozi yoMthetho Wokulawula Izinto Ezinobuthi (TSCA). Lesi sinyathelo sihlose ukuqinisekisa ukuthi ukusetshenziswa okubucayi kwe-dichloromethane kungasetshenziswa ngokuphephile ngohlelo oluphelele lokuvikela abasebenzi. Lo mthetho uzoqala ukusebenza zingakapheli izinsuku ezingama-60 ngemuva kokushicilelwa kwawo kwi-Federal Register.
I-Dichloromethane iyikhemikhali eyingozi, engabangela izinhlobo ezahlukene zomdlavuza kanye nezinkinga ezinkulu zempilo, okuhlanganisa umdlavuza wesibindi, umdlavuza wamaphaphu, umdlavuza webele, umdlavuza wobuchopho, i-leukemia kanye nomdlavuza wesistimu yezinzwa ephakathi. Ngaphezu kwalokho, futhi ithwala ingozi yobuthi bemizwa kanye nokulimala kwesibindi. Ngakho-ke, ukuvinjelwa kudinga izinkampani ezifanele ukuthi zinciphise kancane kancane ukukhiqizwa, ukucubungula, kanye nokusatshalaliswa kwe-dichloromethane ngezinjongo zabathengi kanye nezimboni eziningi nezentengiselwano, okuhlanganisa nokuhlobisa ikhaya. Ukusetshenziswa kwabathengi kuzoqedwa phakathi nonyaka owodwa, kanti ukusetshenziswa kwezimboni nezentengiselwano kuzovinjelwa phakathi neminyaka emibili.
Ezimweni ezimbalwa ezinokusetshenziswa okubalulekile ezindaweni ezithuthuke kakhulu, lokhu kuvinjelwa kuvumela ukugcinwa kwe-dichloromethane futhi kusungula indlela ebalulekile yokuvikela abasebenzi - Uhlelo Lokuvikela Amakhemikhali Emsebenzini. Lolu hlelo lubeka imikhawulo eqinile yokuchayeka, izidingo zokuqapha, kanye nezibopho zokuqeqeshwa kwabasebenzi kanye nezaziso ze-dichloromethane ukuvikela abasebenzi engcupheni yomdlavuza nezinye izinkinga zempilo ezibangelwa ukuchayeka kumakhemikhali anjalo. Ezindaweni zokusebenza ezizoqhubeka nokusebenzisa i-dichloromethane, iningi lezinkampani kudingeka zilandele imithetho emisha zingakapheli izinyanga ezingu-18 ngemuva kokukhishwa kwemithetho yokuphathwa kwezingozi futhi zenze ukuqapha njalo.
Lokhu kusetshenziswa okubalulekile kufaka phakathi:
Ukukhiqiza amanye amakhemikhali, njengamakhemikhali abalulekile okuqandisa angaqeda kancane kancane ama-hydrofluorocarbon ayingozi ngaphansi koMthetho Wokusungula Nokukhiqiza WaseMelika i-Bipartisan;
Ukukhiqizwa kwezihlukanisi zamabhethri ezimoto zikagesi;
Izinsiza zokucubungula ezinhlelweni ezivaliwe;
Ukusetshenziswa kwamakhemikhali asebenza elabhorethri;
Ukukhiqizwa kwepulasitiki nerabha, okuhlanganisa nokukhiqizwa kwe-polycarbonate;
Ukushisela isinyibilikisi.
