Musi wa30 Kubvumbi, 2024, United States Environmental Protection Agency (EPA) yakarambidza kushandiswa kwe dichloromethane ine mabasa akawanda zvichienderana nemitemo yekutonga njodzi yeToxic Substances Control Act (TSCA). Danho iri rine chinangwa chekuona kuti dichloromethane inoshandiswa zvakanyanya inogona kushandiswa zvakachengeteka kuburikidza nechirongwa chakazara chekudzivirira vashandi. Kurambidzwa uku kuchatanga kushanda mukati memazuva makumi matanhatu mushure mekuburitswa kwayo muFederal Register.
Dichloromethane ikemikari ine njodzi, iyo inogona kukonzera mhando dzakasiyana dzekenza nematambudziko makuru ehutano, anosanganisira kenza yechiropa, kenza yemapapu, kenza yemazamu, kenza yeuropi, leukemia uye kenza yetsinga dzepakati. Pamusoro pezvo, inewo njodzi yekukuvadzwa netsinga uye kukuvara kwechiropa. Nokudaro, kurambidzwa uku kunoda kuti makambani akakodzera aderedze zvishoma nezvishoma kugadzirwa, kugadziriswa, uye kugoverwa kwe dichloromethane kune vatengi uye maindasitiri nemabhizimisi akawanda, kusanganisira kushongedza dzimba. Kushandiswa kwevatengi kuchabviswa mukati megore rimwe chete, ukuwo kushandiswa kweindasitiri nemabhizimisi kucharambidzwa mukati memakore maviri.
Kune zvimwe zviitiko zvine mashandisirwo akakosha munzvimbo dzakabudirira zvikuru, kurambidzwa uku kunobvumira kuchengetedzwa kwe dichloromethane uye kunogadza nzira huru yekudzivirira vashandi - iyo Workplace Chemical Protection Plan. Iyi hurongwa inoisa miganhu yakaoma yekusvibiswa, zvinodiwa zvekutarisa, uye kudzidziswa kwevashandi uye zvisungo zvekuzivisa nezve dichloromethane kudzivirira vashandi kubva mukutyisidzirwa kwegomarara nezvimwe zvinetso zvehutano zvinokonzerwa nekusvibiswa nemakemikari akadaro. Kune nzvimbo dzebasa dzicharamba dzichishandisa dichloromethane, makambani mazhinji anofanirwa kutevedzera mitemo mitsva mukati memwedzi gumi nemisere mushure mekuburitswa kwemitemo yekutarisira njodzi uye kuita nguva dzose kutarisa.
Mashandisirwo aya akakosha anosanganisira:
Kugadzira mamwe makemikari, akadai semakemikari akakosha ekufiriji anogona kubvisa zvishoma nezvishoma mahydrofluorocarbon ane njodzi pasi peBipartisan American Innovation and Manufacturing Act;
Kugadzirwa kwezviparadzanisa mabhatiri emotokari zvemagetsi;
Zvibatsiro zvekugadzirisa mumasisitimu akavharwa;
Kushandiswa kwemakemikari emurabhoritari;
Kugadzira mapurasitiki nerabha, kusanganisira kugadzirwa kwepolycarbonate;
Kusonta zvinonyungudutsa.
