Mumitemo yakarongwa yakaburitswa musi wa3 Chivabvu, EPA yakaronga kurambidza kushandiswa kwakawanda kwe dichloromethane, inozivikanwawo se dichloromethane, chinhu chinobatsira pakugadzirisa zvinhu. Inoshandiswa mumhando dzakasiyana dzemashandisirwo evatengi nevemabhizinesi, kusanganisira zvinonamira nezvisimbiso, zvigadzirwa zvemotokari, uye zvinobvisa pendi nependi. Kemikari iyi inogadzirwa yakawanda - pakati pemamiriyoni zana nemakumi mashanu emapaunzi pakati pa2016 na2019, zvichienderana neChemical Data Report (CDR) - saka kurambidzwa, kana kukapasiswa, kwaizova nemigumisiro mikuru kumaindasitiri mazhinji. Kukanganisa kukuru.
Chikumbiro cheEPA chinotaura nezve "njodzi isina musoro yekukuvadza hutano hwevanhu kubva ku dichloromethane pasi pemamiriro ekushandiswa, sezvakanyorwa mutsananguro dzenjodzi dzeEPA pasi peToxic Substances Control Act (TSCA)". kana nharaunda yakatsanangurwa muongororo yenjodzi yeTSCA uye shandisa zvinodiwa kusvika padanho rinodiwa kuitira kuti makemikari asazove nenjodzi isina musoro.
Pamusoro pezvo, mutemo weEPA unoda Chemical Workplace Protection Plan (WCPP), iyo inosanganisira zvinodiwa zvekutevedzera miganhu yekufema uye kutarisa kusvibiswa kwemamiriro ezvinhu ekushandisa nguva dzose dichloromethane. Ichaisawo zvinodiwa zvekuchengetedza zvinyorwa uye zvekuzivisa mamiriro ezvinhu akati wandei ekushandisa uye inopa zvimwe zvisingatarisirwi kwenguva pfupi kune zvinodiwa zvekushandisa zvinogona kukonzera kukuvara kukuru kuchengetedzeka kwenyika nezvivakwa zvakakosha.
Makambani anogadzira, anopinza, anogadzirisa, anogovera, anoshandisa kana kurasa methylene chloride kana zvigadzirwa zvine methylene chloride anogona kukanganiswa nemutemo wakarongwa. Mutemo wakarongwa unoratidza mapoka anopfuura makumi mana emaindasitiri anogona kutevedzera mutemo uyu, anosanganisira: makemikari akawanda; nzvimbo dzekutakura mafuta; kugadzirwa kwemakemikari epakutanga neezvinhu zvisina kugadzirwa; kuraswa kwemarara ane njodzi; makambani ekugadzirisa zvinhu; pendi nependi. vagadziri; makondirakita epombi nemhepo inotonhodza; makondirakita ekupenda nemadziro; zvitoro zvezvikamu zvemotokari nezvishongedzo; kugadzirwa kwemidziyo yemagetsi nezvikamu; kugadzirwa kwemidziyo yekubatanidza nekusonesa; vatengesi vemotokari itsva nedzakamboshandiswa; mabasa ekuchenesa nekuwachira; pamwe nemadhori, matoyi nemitambo. kugadzirwa.
Mutemo wakarongwa unotaura kuti "Inenge 35 muzana yekugadzirwa kwemethylene chloride pagore inoshandiswa pakurapa uye haitungamirirwi kana kudzorwa neTSCA." )(B) Chero chinhu chisiri tsananguro ye "makemikari" mundima (ii)-(vi). Izvi zvinoregererwa "zvinosanganisira ... chero chikafu, chinowedzera kudya, mushonga, chizoro, kana mudziyo, sezvakatsanangurwa muChikamu 201 cheFederal Food, Drug, and Cosmetic Act, inogadzirwa, inogadziriswa, kana kutengeswa sechikafu, chinowedzera chikafu, mushonga, chizoro kana mudziyo…"
Kune maindasitiri anogona kunge akanganiswa nekurambidzwa uku, zvakakosha kutanga kufunga nezvedzimwe nzira. Kuongororwa kweEPA kwedzimwe nzira dzekushandisa methylene chloride kwakaratidza dzimwe nzira dzekushandisa dzakasiyana-siyana dzakadai semaglues, sealants, degreasers, pendi ne coating removers, sealants, uye mafuta nemafuta. Zvisinei, zvinofanira kucherechedzwa kuti hapana dzimwe nzira dzekuwedzera tekinoroji (kusanganisira) dzakawanikwa. Kuongororwa kwedzimwe nzira "hakurudzire zvigadzirwa zvinofanirwa kushandiswa panzvimbo pe dichloromethane; asi, chinangwa chayo ndechekupa runyorwa rwezvigadzirwa nemakemikari zvinogona kushandiswa uye njodzi dzazvo zvichienzaniswa ne dichloromethane, kuitira kuti pave nekuongorora dzimwe nzira dzinogona kushandiswa. Mhedzisiro yacho inoonekwa sechikamu cheTSCA Section 6(a) dichloromethane rule." Mhinduro pamusoro pemutemo wakarongwa dzinofanira kugamuchirwa pasati papera Chikunguru 3 uye dziripo kuburikidza ne federal electronic rulemaking portal pa https://www.regulation.gov.
Chiziviso: Nekuda kwehunhu hwekuvandudzwa uku, ruzivo rwuri pano runogona kusashanda mumamiriro ese ezvinhu, uye harufanirwe kushandiswa pasina zano repamutemo rakanangana nemamiriro ako chaiwo.
