I-Arhente yoKhuseleko lweNdalo icebise ukuba ithintelwe ukusetyenziswa kwe-methylene chloride, ikhemikhali abathi iyingozi empilweni kwaye ide ibulale, ukuze kukhuselwe impilo yoluntu.
Esi siphakamiso siza kuthintela ukusetyenziswa kwe-dichloromethane kuzo zonke iimeko zabathengi nakwimisebenzi emininzi yemizi-mveliso neyezorhwebo. I-Dichloromethane isetyenziswa kwizixhobo zokucoca ii-aerosol, kwizixhobo zokucoca iibhrashi zepeyinti nezogqumayo, kwizixhobo zokuncamathelisa kunye nezivali zorhwebo, nakwimveliso yezinye iikhemikhali kwiindawo zoshishino.
Olu thintelo lwaziswa njengenxalenye yoMthetho woLawulo lweZinto ezinobungozi, owanika i-EPA amandla okufuna ingxelo, ukugcinwa kweerekhodi, kunye nokuvavanywa, phakathi kweminye imiqathango. Ngo-2019, i-EPA yathintela ukusetyenziswa kwe-dichloromethane ngabathengi ngokuyisusa kwi-paint strippers.
Ubuncinane abantu abangama-85 basweleke ngenxa yokudibana nale khemikhali ukususela ngo-1980, ngokutsho kwe-EPA. I-Arhente yoKhuseleko lweNdalo ithe la matyala abandakanya kakhulu abasebenzi abenza umsebenzi wekontrakthi yokuphucula ikhaya. Le arhente ithi kukho abantu "abaninzi" abaye bafumana iziphumo zempilo ezibi nezihlala ixesha elide emva kokudibana ne-methylene chloride. I-EPA ikwachonge iziphumo ezibi zempilo, kubandakanya ubuthi be-neurotoxic, iziphumo zesibindi, kunye nomhlaza ngokuphefumla kunye nokunxibelelana nolusu.
Le arhente ifumanise ukuba i-dichloromethane ibeka “umngcipheko ongafanelekanga wokwenzakalisa impilo phantsi kweemeko zokusetyenziswa” ngenxa yemingcipheko kubasebenzi abachaphazeleka ngokuthe ngqo okanye ngokungathanga ngqo yikhemikhali, abathengi abasebenzisa le khemikhali, kunye nabantu abachaphazeleka yikhemikhali.
“Isayensi engasemva kwe-methylene chloride icacile, kwaye ukuvezwa kunokubangela iziphumo ezibi zempilo kwanokufa, nto leyo iyinyani kwiintsapho ezininzi ezilahlekelwe ngabantu ababathandayo ngenxa yetyhefu ebukhali,” utshilo umphathi we-EPA uMichael S. Regan. inkomfa eyabhengeza oko. “Yiyo loo nto i-EPA ithatha inyathelo ngokucebisa ukukhusela impilo yabasebenzi ngokungenisa ulawulo olungqongqo lwendawo yokusebenza oluya kuthintela ukusetyenziswa kwesi sikhemikhali kwaye lunciphise ukuvezwa kuzo zonke ezinye iimeko.”
I-EPA ithe injongo yokuvalwa okucetywayo kukukhusela abantu kwingozi kwaye ivumele kuphela i-methylene chloride ukuba isetyenziswe phantsi kweemeko zomsebenzi ezilawulwa kakhulu, nto leyo eya kunciphisa ukuvezwa. Ukuveliswa, ukucutshungulwa kunye nokusasazwa kwe-dichloromethane kuya kuyeka kwiinyanga ezili-15 ezizayo. Apho isindululo sathintela 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 kweendlela ezintsha zokukhusela iikhemikhali kunye nokuthatha amanyathelo asele edlulile ixesha elide okukhusela ngcono impilo yoluntu,” utshilo uReagan.
