Ngomhla wama-30 ku-Epreli, ngo-2024, i-United States Environmental Protection Agency (EPA) ikhuphe umthetho wokuthintela ukusetyenziswa kwe-dichloromethane eneenjongo ezininzi ngokuhambelana nemigaqo yolawulo lomngcipheko we-Toxic Substances Control Act (TSCA). Eli nyathelo lijolise ekuqinisekiseni ukuba i-dichloromethane esetyenziswa kakhulu ingasetyenziswa ngokukhuselekileyo ngenkqubo yokukhusela abasebenzi ebanzi. Lo mthetho uza kuqala ukusebenza zingadlulanga iintsuku ezingama-60 emva kokupapashwa kwayo kwi-Federal Register.
I-Dichloromethane yikhemikhali eyingozi, enokubangela iintlobo ngeentlobo zomhlaza kunye neengxaki zempilo ezinzulu, kubandakanya umhlaza wesibindi, umhlaza wemiphunga, umhlaza webele, umhlaza wobuchopho, i-leukemia kunye nomhlaza wenkqubo yemithambo-luvo ephakathi. Ukongeza, ikwanomngcipheko wobuthi bemithambo-luvo kunye nomonakalo wesibindi. Ke ngoko, ukuvinjelwa kufuna iinkampani ezifanelekileyo ukuba zinciphise kancinci imveliso, ukucubungula, kunye nokusasazwa kwe-dichloromethane kwiinjongo zabathengi kunye nezona mveliso kunye nezorhwebo, kubandakanya ukuhombisa ikhaya. Ukusetyenziswa kwabathengi kuya kupheliswa kungakapheli unyaka omnye, ngelixa ukusetyenziswa kwemizi-mveliso kunye nezorhwebo kuya kuvalwa kungakapheli iminyaka emibini.
Kwiimeko ezimbalwa ezinokusetyenziswa okubalulekileyo kwiindawo eziphucukileyo kwezoshishino, olu thintelo luvumela ukugcinwa kwe-dichloromethane kwaye lumisela indlela ephambili yokukhusela abasebenzi - iSicwangciso soKhuseleko lweeKhemikhali kwindawo yoMsebenzi. Esi sicwangciso sibeka imida engqongqo yokuvezwa, iimfuno zokubeka esweni, kunye noqeqesho lwabasebenzi kunye nezibophelelo zesaziso ze-dichloromethane ukukhusela abasebenzi kwingozi yomhlaza kunye nezinye iingxaki zempilo ezibangelwa kukuvezwa kwiikhemikhali ezinjalo. Kwiindawo zokusebenza eziza kuqhubeka nokusebenzisa i-dichloromethane, uninzi lweenkampani kufuneka zithobele imithetho emitsha zingadlulanga iinyanga ezili-18 emva kokukhutshwa kwemithetho yolawulo lomngcipheko kwaye ziqhube nokubeka esweni rhoqo.
Ezi ndlela ziphambili zokusetyenziswa ziquka:
Ukuvelisa ezinye iikhemikhali, ezifana neekhemikhali ezibalulekileyo zokukhenkcisa ezinokususa kancinci kancinci ii-hydrofluorocarbons eziyingozi phantsi koMthetho we-Bipartisan American Innovation and Manufacturing Act;
Ukuveliswa kwezinto zokwahlula iibhetri zezithuthi zombane;
Izixhobo zokucubungula kwiinkqubo ezivaliweyo;
Ukusetyenziswa kweekhemikhali zelebhu;
Ukwenziwa kweplastiki nerabha, kuquka ukuveliswa kwepolycarbonate;
Ukuwelda isinyibilikisi.
