I-Ejensi yokuVikelwa kweBhoduluko iphakamise ukukhandela ukusetjenziswa kwe-methylene chloride, ikhemikhali abathi iyingozi epilweni begodu iyabulala, ukuvikela ipilo yomphakathi.
Isiphakamiso sizokukhandela ukusetjenziswa kwe-dichloromethane kibo boke ubujamo babathengi begodu neenhloso ezinengi zezebubulo nezamabhizinisi. I-dichloromethane isetjenziselwa ukukhipha amafutha we-aerosol, ukuhlanza ibhrashi yokupenda nokugcoba, ukunamathelana kwezokuthengisa nokuvala, kanye nokukhiqizwa kwamanye amakhemikhali eendaweni zamabubulo.
Ukuvinjelwa kwethulwe njengengcenye yomThetho wokulawula iindakamizwa ezinobuthi, owanikela i-EPA ikghono lokufuna ukubika, ukugcinwa kwamarekhodi, nokuhlolwa, hlangana neminye imikhawulo. Ngomnyaka ka-2019, i-EPA yavimbela ukusetjenziswa kwabathengi kwe-dichloromethane ngokuyisusa eensetjenzisweni zokukhipha ipende.
Okungenani abantu abangama-85 bahlongakele ngokuvezwa kulekhemikhali solo kwango-1980, ngokuya nge-EPA. I-Ejensi yokuVikelwa kweBhoduluko ithe amacala la aphathelene nabasebenzi abenza umsebenzi wekontraga yokuthuthukisa amakhaya. I-ejensi ithe kunabantu "banengi" abahlangabezane nemiraro yepilo yesikhathi eside ngemva kokuvezwa ku-methylene chloride. I-EPA nayo ikhombe imiphumela emimbi yezamaphilo, okufakahlangana ukulimala kwemizwa, imiphumela yesibindi, kanye nomdlavuza ngokuphefumula nokuthintana nesikhumba.
I-ejensi inqume bona i-dichloromethane ibeka "ingozi engazwakaliko yokulimaza ipilo ngaphasi kwemibandela yokusetjenziswa" ngebanga lobungozi ebasebenzini abavezwe ngqo nofana ngokungakaqondi kukhemikhali, abathengi abasebenzisa ikhemikhali, nabantu abavezwe kukhemikhali.
"Isayensi ngemuva kwe-methylene chloride icacile, begodu ukuvezwa kungabanga imiphumela emimbi khulu yezamaphilo ngitjho nokuhlongakala, okuyinto ekhona emindenini eminengi khulu elahlekelwe babantu abayithandako ngebanga lokutjhejwa," kutjho umlawuli we-EPA u-Michael S. Regan. umhlangano owamemezela lokho. "Kungakho i-EPA ithatha amagadango ngokuphakamisa ukuvikela ipilo yabasebenzi ngokwethula imithetho eqinileko emsebenzini engavimbela ukusetjenziswa okunengi kwalekhemikhali begodu yehlise ukuvezwa kizo zoke ezinye iimeko."
I-EPA ithe umnqopho wokuvinjelwa okuphakanyisiweko kukuvikela abantu ebungozini begodu kuvumele i-methylene chloride bona isetjenziswe ngaphasi kweemeko ezilawulwa khulu zendawo yokusebenza, okuzokunciphisa ukuvezwa. Ukukhiqizwa, ukusetjenziswa nokusabalaliswa kwe-dichloromethane kuzokuphela eenyangeni ezili-15 ezizako. Lapho isiphakamiso sivimbele khona ikhemikhali, ukuhlaziywa kwe-EPA kwathola bona eminye imikhiqizo “eneendleko ezifanako nokusebenza kuhle ... iyatholakala ngokuvamileko.”
"Ukuvinjelwa okuphakanyisiweko okungumlando kutjengisa ituthuko ekulu esiyenzileko ekusebenziseni iindlela ezitjha zokuvikela amakhemikhali nokuthatha amagadango ebegade sele alindele ukuvikela ngcono ipilo yomphakathi," kutsho u-Reagan.
