Kuletsa dichloromethane kwayambitsidwa, kutulutsidwa koletsedwa kugwiritsidwa ntchito m'mafakitale

Pa Epulo 30, 2024, bungwe la United States Environmental Protection Agency (EPA) linapereka lamulo loletsa kugwiritsa ntchito dichloromethane yogwiritsidwa ntchito m'njira zosiyanasiyana motsatira malamulo okhudza kupewa zoopsa a Toxic Substances Control Act (TSCA). Cholinga cha lamuloli ndikuwonetsetsa kuti dichloromethane yogwiritsidwa ntchito mozama ingagwiritsidwe ntchito mosamala kudzera mu pulogalamu yonse yoteteza antchito. Lamuloli lidzayamba kugwira ntchito mkati mwa masiku 60 kuchokera pamene lafalitsidwa mu Federal Register.

Dichloromethane ndi mankhwala oopsa, omwe angayambitse khansa zosiyanasiyana komanso mavuto aakulu azaumoyo, kuphatikizapo khansa ya chiwindi, khansa ya m'mapapo, khansa ya m'mawere, khansa ya muubongo, khansa ya m'magazi ndi khansa ya m'mitsempha yapakati. Kuphatikiza apo, ilinso ndi chiopsezo cha poizoni wa mitsempha ndi kuwonongeka kwa chiwindi. Chifukwa chake, chiletsochi chikufuna makampani oyenerera kuti achepetse pang'onopang'ono kupanga, kukonza, ndi kufalitsa dichloromethane pazinthu zambiri zamafakitale ndi zamalonda, kuphatikizapo kukongoletsa nyumba. Kugwiritsa ntchito kwa ogula kudzathetsedwa mkati mwa chaka chimodzi, pomwe kugwiritsa ntchito mafakitale ndi zamalonda kudzaletsedwa mkati mwa zaka ziwiri.

Pa zochitika zingapo zomwe zimagwiritsidwa ntchito kwambiri m'malo otukuka kwambiri, chiletsochi chimalola kuti dichloromethane isungidwe ndipo chimakhazikitsa njira yofunika kwambiri yotetezera antchito - Ndondomeko Yoteteza Mankhwala Pantchito. Dongosololi limakhazikitsa malire okhwima okhudzana ndi kukhudzana ndi anthu, zofunikira pakuwunika, komanso maphunziro a antchito ndi zidziwitso za dichloromethane kuti ateteze antchito ku chiopsezo cha khansa ndi mavuto ena azaumoyo omwe amayamba chifukwa cha kukhudzana ndi mankhwala otere. Kwa malo ogwirira ntchito omwe apitiliza kugwiritsa ntchito dichloromethane, makampani ambiri ayenera kutsatira malamulo atsopano mkati mwa miyezi 18 atatulutsidwa malamulo oyang'anira zoopsa ndikuchita kuwunika nthawi zonse.

Ntchito zazikuluzi zikuphatikizapo:

Kupanga mankhwala ena, monga mankhwala ofunikira oziziritsira omwe pang'onopang'ono amatha kuchotsa ma hydrofluorocarbons oopsa motsatira Bipartisan American Innovation and Manufacturing Act;

Kupanga zida zolekanitsira mabatire a magalimoto amagetsi;

Zothandizira kukonza zinthu m'makina otsekedwa;

Kugwiritsa ntchito mankhwala a labotale;

Kupanga pulasitiki ndi rabara, kuphatikizapo kupanga polycarbonate;

Kuwotcherera kwa zosungunulira.
