I-Environmental Protection Agency iphakamise ukuvimbela ukusetshenziswa okuningi kwe-methylene chloride, ikhemikhali abathi iyingozi empilweni futhi ibulala ngisho nangokwengeziwe, ukuze kuvikelwe impilo yomphakathi.
Lesi siphakamiso sizovimbela ukusetshenziswa kwe-dichloromethane kuzo zonke izimo zabathengi kanye nezinjongo eziningi zezimboni nezentengiselwano. I-Dichloromethane isetshenziswa kuma-degreaser e-aerosol, kuma-brush cleaner opende nokumboza, kuma-glue anamathelayo nakuma-sealant ezentengiselwano, kanye nokukhiqizwa kwamanye amakhemikhali ezindaweni zezimboni.
Lokhu kuvinjelwa kwethulwa njengengxenye yoMthetho Wokulawula Izinto Ezinobuthi, owanikeza i-EPA ikhono lokudinga ukubika, ukugcinwa kwamarekhodi, kanye nokuhlolwa, phakathi kweminye imikhawulo. Ngo-2019, i-EPA yavimbela ukusetshenziswa kwe-dichloromethane ngabathengi ngokuyisusa kuma-paint strippers.
Okungenani abantu abangu-85 bashonile ngenxa yokuchayeka kule khemikhali kusukela ngo-1980, ngokusho kwe-EPA. I-Environmental Protection Agency ithe amacala ahilela kakhulu abasebenzi abenza umsebenzi wenkontileka yokuthuthukisa ikhaya. Le nhlangano ithe kunabantu "abaningi kakhulu" abaye babhekana nemiphumela emibi yezempilo ngemuva kokuchayeka ku-methylene chloride. I-EPA iphinde yathola imiphumela emibi yezempilo, okuhlanganisa ubuthi be-neurological, imiphumela yesibindi, kanye nomdlavuza ngokuphefumula kanye nokuxhumana nesikhumba.
I-ejensi inqume ukuthi i-dichloromethane ibeka “ingozi engafanele yokulimaza impilo ngaphansi kwezimo zokusetshenziswa” ngenxa yezingozi kubasebenzi abachayeke ngokuqondile noma ngokungaqondile kumakhemikhali, abathengi abasebenzisa amakhemikhali, kanye nabantu abachayeke kumakhemikhali.
“Isayensi ngemuva kwe-methylene chloride icacile, futhi ukuchayeka kungabangela imiphumela emibi yezempilo ngisho nokufa, okuyinto eyenzeka emindenini eminingi kakhulu elahlekelwe abathandekayo bayo ngenxa yobuthi obuyingozi,” kusho umhlangano womphathi we-EPA uMichael S. Regan. owamemezela lokhu. “Yingakho i-EPA ithatha isinyathelo ngokuphakamisa ukuvikela impilo yabasebenzi ngokuletha izilawuli eziqinile zomsebenzi ezizovimbela ukusetshenziswa kwaleli khemikhali futhi zinciphise ukuchayeka kuzo zonke ezinye izimo.”
I-EPA ithe umgomo wokuvinjelwa okuhlongozwayo ukuvikela abantu engcupheni futhi kuvunyelwe kuphela i-methylene chloride ukuthi isetshenziswe ngaphansi kwezimo zomsebenzi ezilawulwa kakhulu, okuzonciphisa ukuvezwa. Ukukhiqizwa, ukucubungula kanye nokusatshalaliswa kwe-dichloromethane kuzophela zingakapheli izinyanga eziyi-15 ezizayo. Lapho isiphakamiso sivimbe khona ikhemikhali, ukuhlaziywa kwe-EPA kuthole ukuthi imikhiqizo ehlukile "enezindleko ezifanayo kanye nokusebenza kahle ... ngokuvamile iyatholakala."
“Lokhu kuvinjelwa okuhlongozwayo okungokomlando kubonisa intuthuko ebalulekile esiyenzile ekusebenziseni izindlela ezintsha zokuphepha kwamakhemikhali kanye nokuthatha izinyathelo ezithathe isikhathi eside ukuvikela impilo yomphakathi kangcono,” kusho uReagan.
