Mumitemo yakarongwa yakaburitswa musi wa3 Chivabvu, US Environmental Protection Agency inokurudzira kurambidza kushandiswa kwe dichloromethane, inozivikanwawo se dichloromethane, chinhu chinobatsira pakugadzirisa zvinhu. Inoshandiswa mumhando dzakasiyana dzezvinhu zvinoshandiswa nevatengi nevemabhizinesi, kusanganisira zvinonamira nezvisimbiso, zvigadzirwa zvemotokari, uye zvinobvisa pendi nependi. Kemikari iyi inogadzirwa nehuwandu hwakawanda - pakati pe £100 miriyoni ne £500 miriyoni kubva muna 2016 kusvika 2019, zvichienderana neChemical Data Report (CDR) - saka kurambidzwa uku, kana kukapasiswa, kwaizokanganisa zvikuru maindasitiri mazhinji.
Chikumbiro cheEPA chinotaura nezve "njodzi isina musoro kuhutano hwevanhu iyo dichloromethane inokonzera pasi pemamiriro ekushandiswa, sezvakanyorwa mutsananguro dzenjodzi dzeEPA pasi peToxic Substances Control Act (TSCA)". Kuongororwa kwenjodzi dzeTSCA nekushandiswa kwezvinodiwa kusvika pamwero unodiwa kuona kuti kemikari iyi haichakonzere njodzi isina musoro.
Pamusoro pezvo, mutemo weEPA unoda Chemical Workplace Protection Plan (WCPP), iyo inosanganisira zvinodiwa zvekutevedzera mitemo yekufemerwa uye kutarisa kuratidzwa kwekushandiswa kwemethylene chloride nguva dzose. Ichaisawo zvinodiwa zvekuchengetedza zvinyorwa uye zvekuzivisa pasi pemamiriro akasiyana ekushandisa uye inopa zvimwe zvinorambidzwa 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 kuvharwa nemutemo uyu, anosanganisira: makemikari akawanda, nzvimbo dzemafuta nematerminal, kugadzirwa kwemakemikari epakutanga neezvinhu zvisina kugadzirwa, kuraswa kwemarara ane njodzi, kudzokorodzwa kwezvinhu, vagadziri vependi nependi; makondirakita epombi nemhepo inotonhodza; makondirakita ekupenda nekupenda madziro; zvitoro zvezvikamu zvemotokari nezvishongedzo; kugadzirwa kwemidziyo yemagetsi nezvikamu; kugadzirwa kwemidziyo yekusonesa; vatengesi vemotokari itsva nedzakamboshandiswa; mabasa ekuchenesa nekuwachira mbatya; kugadzira zvidhori, matoyi nemitambo.
Mutemo wakarongwa unotaura kuti "Inenge 35 muzana yekugadzirwa kwegore negore kwemethylene chloride inoshandiswa pamishonga isiri pasi peTSCA uye isiri pasi pemutemo uyu." yakabviswa kubva mutsanangudzo ye "makemikari" muzvikamu (B)(ii) kusvika (vi). Izvi zvinoregererwa "zvinosanganisira ... chero chikafu, chikafu chinowedzera, mushonga, chizoro, kana mudziyo, sezvakatsanangurwa muChikamu 201 cheFederal Food, Drug, and Cosmetic Act, kana chagadzirwa, chakagadziriswa, kana kugoverwa mukutengeserana kuti chishandiswe semishonga. , zvizoro kana zvishandiso…"
Kune maindasitiri achakanganiswa nekurambidzwa uku, zvakakosha kutanga kutsvaga dzimwe nzira. Kuongororwa kweEPA kwezvimwe zvinoshandiswa panzvimbo pemethylene chloride kwakaratidza dzimwe nzira dzekushandisa dzakasiyana-siyana dzakadai semaglues, sealants, degreasers, pendi ne coating removers, sealants, uye mafuta nemafuta. Zvisinei, zvinofanira kucherechedzwa kuti hapana zvinotsiva zve tekinoroji (pakati pezvimwe) zvakawanikwa. Kuongororwa kwezvimwe nzira "hakurudzire zvigadzirwa kuti zvishandiswe panzvimbo pe dichloromethane; asi, chinangwa chayo ndechekupa runyorwa rwezvigadzirwa zvinogona kushandiswa panzvimbo pe dichloromethane; asi, chinangwa chayo ndechekupa runyorwa rwezvigadzirwa zvinogona kushandiswa uye zvinhu zvine makemikari uye njodzi dzazvo zvine chekuita ne dichloromethane, kuve nechokwadi chekuti mhedzisiro yekuyedza dzimwe nzira dzinoonekwa sechikamu chemitemo yeTSCA Chikamu 6(a) yemethylene chloride." Mhinduro pamusoro pemutemo wakarongwa dzinofanira kugamuchirwa kwete mushure meChikunguru 3 uye dziripo pa federal electronic rulemaking portal pa https://www.regulations.gov.
Chiziviso: Nekuda kwehunhu hwekuvandudzwa uku, ruzivo rwuri pano runogona kusashanda mumamiriro ese ezvinhu, uye harufanirwe kushandiswa pasina zano repamutemo rakanangana nemamiriro ako chaiwo.
