Ukuvalwa kwe-dichloromethane yaziswa, ukukhutshwa okuthintelweyo kusetyenziso lwemizi-mveliso

Ngomhla wama-30 ku-Epreli 2024, i-Arhente yoKhuseleko lweNdalo yase-United States (i-EPA) yakhupha isithintelo sokusetyenziswa kwe-dichloromethane eneenjongo ezininzi ngokwemigaqo yolawulo lwengozi yoMthetho woLawulo lweZinto eziyityhefu (TSCA). Eli nyathelo lijolise ekuqinisekiseni ukuba ukusetyenziswa okubalulekileyo kwe-dichloromethane kunokusetyenziswa ngokukhuselekileyo ngenkqubo ebanzi yokukhusela abasebenzi. Ukuvalwa kuya kusebenza kwiintsuku ze-60 emva kokupapashwa kwayo kwiRejista ye-Federal.

I-Dichloromethane yikhemikhali eyingozi, enokuthi ibangele iintlobo zomhlaza kunye neengxaki ezinzulu zempilo, kubandakanya umhlaza wesibindi, umhlaza wemiphunga, umhlaza wamabele, umhlaza wobuchopho, i-leukemia kunye nomhlaza we-nervous system. Ukongeza, ikwathwala umngcipheko we-neurotoxicity kunye nomonakalo wesibindi. Ngoko ke, ukuvinjelwa kufuna ukuba iinkampani ezifanelekileyo zinciphise ngokuthe ngcembe imveliso, ukusetyenzwa, kunye nokuhanjiswa kwe-dichloromethane kubathengi kunye neenjongo ezininzi zoshishino kunye nezorhwebo, kubandakanywa nokuhombisa ikhaya. Ukusetyenziswa kwabathengi kuya kupheliswa kwisithuba sonyaka omnye, ngelixa ukusetyenziswa kwemizi-mveliso nezorhwebo kuya kuvalwa kwisithuba seminyaka emibini.

Kwiimeko ezimbalwa ezinokusetyenziswa okubalulekileyo kwiindawo eziphakamileyo kakhulu, oku kuvinjelwa kuvumela ukugcinwa kwe-dichloromethane kunye nokuseka indlela yokukhusela umsebenzi obalulekileyo - iSicwangciso soKhuseleko lweMichiza yoMsebenzi. Esi sicwangciso sibeka imida engqongqo yokuvezwa, iimfuno zokubeka iliso, kunye noqeqesho lwabasebenzi kunye nezibophelelo zesaziso se-dichloromethane ukukhusela abasebenzi kwisisongelo somhlaza kunye nezinye iingxaki zempilo ezibangelwa kukuchanabeka kwimichiza enjalo. Kwiindawo zokusebenza eziya kuqhubeka zisebenzisa i-dichloromethane, uninzi lweenkampani kufuneka zithobele imimiselo emitsha kwiinyanga ezili-18 emva kokukhululwa kwemithetho yokulawula umngcipheko kunye nokubeka iliso rhoqo.

Olu setyenziso luphambili lubandakanya:

Ukuvelisa ezinye iikhemikhali, ezifana neekhemikhali ezibalulekileyo zefriji ezinokuthi ngokuthe ngcembe zikhuphe ii-hydrofluorocarbons ezinobungozi phantsi kwe-Bipartisan American Innovation and Manufacturing Act;

Ukuveliswa kwezahluli zebhetri yemoto yombane;

Ukuncedisa ukucubungula kwiinkqubo ezivaliweyo;

Ukusetyenziswa kweekhemikhali zaselabhoratri;

Ukuveliswa kweplastiki kunye nerabha, kubandakanywa nokuveliswa kwe-polycarbonate;

Ukuwelda okunyibilikayo.
