I-Arhente yoKhuseleko lweNdalo yase-US icebisa ukuba kuthintelwe ukusetyenziswa kwe-methylene chloride, ikhemikhali ethi inokubangela iingozi zempilo kwanokufa, ukuze kukhuselwe impilo yoluntu.
Esi siphakamiso siza kuthintela ukusetyenziswa kwe-methylene chloride kuzo zonke iimeko zabathengi kunye nokusetyenziswa kakhulu kwimizi-mveliso nakwimizi-mveliso. I-methylene chloride isetyenziswa kwizixhobo zokucoca i-aerosol, kwizixhobo zokucoca iibhrashi zepeyinti kunye ne-coating, kwizixhobo zokuncamathelisa kunye ne-sealants zorhwebo, nakwimveliso yezinye iikhemikhali kwiindawo zoshishino.
Ukuvalwa kwacetywa njengenxalenye yoMthetho woLawulo lweZinto eziTyhefu, othi, phakathi kwezinye izithintelo, unike i-Arhente yoKhuseleko lweNdalo igunya lokumisela iimfuno zengxelo, ukugcinwa kweerekhodi kunye novavanyo. Ngo-2019, i-Arhente yoKhuseleko lweNdalo yathintela umthengi omnye ekusebenziseni i-methylene chloride ngokuyisusa kwi-paint strippers.
Ubuncinane abantu abangama-85 basweleke ngenxa yokuchatshazelwa yile khemikhali ukusukela ngo-1980, ngokutsho kwe-US Environmental Protection Agency. I-EPA ithe uninzi lwamatyala abandakanya abasebenzi abakwizivumelwano zokuphucula amakhaya. Le arhente ithe kukho amatyala "amatsha" abantu abafumana iziphumo zempilo ezinzulu nezihlala ixesha elide emva kokuchatshazelwa yi-methylene chloride. I-Environmental Protection Agency ikwachonge iziphumo ezimbi zempilo ezivela ekuphefumleni nasekunxibelelaneni nolusu, kubandakanya ubuthi bemithambo-luvo, iziphumo zesibindi, kunye nomhlaza.
Le arhente igqibe kwelokuba i-methylene chloride “ibeka umngcipheko ongafanelekanga wokwenzakalisa impilo phantsi kweemeko zokusetyenziswa” ngenxa yeengozi kubasebenzi abachaphazeleka ngokuthe ngqo okanye ngokungathanga ngqo yikhemikhali, abathengi abasebenzisa le khemikhali, kunye nabantu abachaphazeleka yikhemikhali.
“Isayensi kwi-methylene chloride icacile, kwaye ukuchatshazelwa yi-methylene chloride kunokubangela iziphumo ezibi zempilo kwanokufa,” utshilo uMlawuli we-EPA uMichael S. Regan kwingxelo yabezindaba. Le yinyani kwiintsapho ezininzi ezilahlekelwe ngabantu ababathandayo ngenxa yetyhefu ebukhali,” itsho njalo isiphakamiso. “Yiyo loo nto i-Arhente yoKhuseleko lweNdalo ithatha inyathelo ngokucebisa ukuba kuthintelwe ukusetyenziswa kwesi sikhemikhali kwaye kusetyenziswe ulawulo olungqongqo kwiindawo zokusebenza ukukhusela impilo yabasebenzi kunye nokunciphisa ukuchatshazelwa kuzo zonke ezinye iindawo.”
Injongo yokuvalwa okucetywayo kukukhusela abantu kwiingozi nokunciphisa ukuvezwa ngokuvumela ukusetyenziswa kwe-methylene chloride kuphela phantsi kweemeko ezilawulwa ngokungqongqo kwiindawo zokusebenza, itsho i-Environmental Protection Agency. Ukuveliswa, ukucutshungulwa kunye nokusasazwa kwe-methylene chloride kuya kuyeka kwiinyanga ezili-15 ezizayo. Kwimeko apho isindululo sithintela le khemikhali, uhlalutyo lwe-EPA lufumanise ukuba "ezinye iimveliso ezinexabiso elifanayo kunye nokusebenza kakuhle...zifumaneka ngokubanzi."
“Olu thintelo lucetywayo lwembali lubonisa inkqubela phambili ebalulekileyo esiyenzileyo ekuphunyezweni kokhuseleko olutsha lweekhemikhali kunye nokuthatha amanyathelo asele edlulile ukuze kukhuselwe ngcono impilo yoluntu,” utshilo uRegan.
