Musi waKubvumbi 30, 2024, iyo United States Environmental Protection Agency (EPA) yakapa kurambidzwa kwekushandiswa kweakawanda-chinangwa dichloromethane zvinoenderana nenjodzi yekudzora mirau yeToxic Substances Control Act (TSCA). Iyi nhanho ine chinangwa chekuona kuti kushandiswa kwakakosha dichloromethane kunogona kushandiswa zvakachengeteka kuburikidza nehurongwa hwekuchengetedza vashandi hwakakwana. Kurambidzwa kuchaita mukati memazuva makumi matanhatu mushure mekuburitswa kwayo muFederal Register.
Dichloromethane ikemikari ine njodzi, inogona kukonzera akasiyana siyana egomarara uye matambudziko akakomba ehutano, anosanganisira kenza yechiropa, kenza yemapapu, kenza yemazamu, kenza yeuropi, leukemia uye yepakati tsinga system cancer. Mukuwedzera, inotakurawo njodzi yeurotoxicity uye kukuvara kwechiropa. Naizvozvo, kurambidzwa kunoda kuti makambani akakodzera aderedze zvishoma nezvishoma kugadzirwa, kugadzirisa, uye kugovera dichloromethane kune vatengi uye mazhinji maindasitiri uye ekutengesa zvinangwa, kusanganisira kushongedza kwemba. Kushandiswa kwevatengi kuchabviswa mukati megore rimwe, nepo kushandiswa kwemaindasitiri nekutengesa kuchizorambidzwa mukati memakore maviri.
Kune mashoma mashoma ane mashandisirwo akakosha munzvimbo dzakanyanya indasitiri, kurambidzwa uku kunobvumira kuchengetwa kwedichloromethane uye kumisa yakakosha nzira yekudzivirira yevashandi - iyo Workplace Chemical Protection Plan. Urongwa uhwu hunoisa miganho yekuratidzira, yekutarisa zvinodiwa, uye kudzidziswa kwevashandi uye zvisungo zvekuzivisa zve dichloromethane kuchengetedza vashandi kubva mukutyisidzirwa kwegomarara uye mamwe matambudziko ehutano anokonzerwa nekusangana nemakemikari akadaro. Kune nzvimbo dzebasa dzicharamba dzichishandisa dichloromethane, ruzhinji rwemakambani anofanirwa kutevedzera mirairo mitsva mukati memwedzi gumi nemasere mushure mekuburitswa kwemitemo yekutarisira njodzi uye kuita yekutarisa nguva dzose.
Izvi zvakakosha zvinoshandiswa zvinosanganisira:
Kugadzira mamwe makemikari, akadai semakemikari anokosha efiriji anogona zvishoma nezvishoma kubvisa mahydrofluorocarbons anokuvadza pasi peBipartisan American Innovation and Manufacturing Act;
Kugadzirwa kwemagetsi emagetsi bhatiri separators;
Kugadzirisa aids mumasisitimu akavharwa;
Kushandiswa kwemakemikari emurabhoritari;
Kugadzirwa kwepurasitiki uye rabha, kusanganisira kugadzirwa kwepolycarbonate;
Solvent welding.
