Kuletsa kwa dichloromethane kunayambika, kumasulidwa koletsedwa kugwiritsidwa ntchito m'mafakitale

Pa Epulo 30, 2024, bungwe la United States Environmental Protection Agency (EPA) lidaletsa kugwiritsa ntchito dichloromethane wamitundu ingapo molingana ndi malamulo oyendetsera ngozi a Toxic Substances Control Act (TSCA). Kusunthaku kukufuna kuwonetsetsa kuti dichloromethane yofunikira ingagwiritsidwe ntchito mosamala kudzera mu pulogalamu yoteteza ogwira ntchito. Chiletsocho chidzayamba kugwira ntchito mkati mwa masiku 60 pambuyo pofalitsidwa mu Federal Register.

Dichloromethane ndi mankhwala owopsa, omwe angayambitse mitundu ingapo ya khansa komanso mavuto akulu azaumoyo, kuphatikiza khansa ya chiwindi, khansa ya m'mapapo, khansa ya m'mawere, khansa ya muubongo, leukemia ndi khansa yapakati yamanjenje. Kuphatikiza apo, imakhalanso ndi chiopsezo cha neurotoxicity ndi kuwonongeka kwa chiwindi. Choncho, kuletsa kumafuna makampani oyenerera kuti achepetse pang'onopang'ono kupanga, kukonza, ndi kugawa kwa dichloromethane kwa ogula ndi mafakitale ndi malonda ambiri, kuphatikizapo zokongoletsera kunyumba. Kugwiritsa ntchito kwa ogula kudzathetsedwa mkati mwa chaka chimodzi, pomwe kugwiritsa ntchito mafakitale ndi malonda kudzaletsedwa mkati mwa zaka ziwiri.

Kwa zochitika zochepa zogwiritsira ntchito zofunikira m'madera otukuka kwambiri, kuletsa kumeneku kumalola kusungidwa kwa dichloromethane ndikukhazikitsa njira yofunika kwambiri yotetezera ogwira ntchito - Workplace Chemical Protection Plan. Dongosololi limakhazikitsa malire owonetsetsa, zofunikira zowunikira, komanso maphunziro a antchito ndi zidziwitso za dichloromethane kuteteza ogwira ntchito ku chiwopsezo cha khansa ndi zovuta zina zathanzi zomwe zimadza chifukwa chokhudzidwa ndi mankhwalawa. Kwa malo ogwirira ntchito omwe apitilize kugwiritsa ntchito dichloromethane, makampani ambiri ayenera kutsatira malamulo atsopano mkati mwa miyezi 18 atatulutsidwa malamulo owongolera zoopsa ndikuwunika pafupipafupi.

Ntchito zazikuluzikulu izi zikuphatikizapo:

Kupanga mankhwala ena, monga mankhwala ofunikira a firiji omwe amatha kuchotsa pang'onopang'ono ma hydrofluorocarbons owopsa pansi pa Bipartisan American Innovation and Manufacturing Act;

Kupanga olekanitsa batire ya galimoto yamagetsi;

Zothandizira pokonza mu machitidwe otsekedwa;

Kugwiritsa ntchito mankhwala a laboratory;

Kupanga pulasitiki ndi mphira, kuphatikizapo kupanga polycarbonate;

Kuwotchera zosungunulira.
