IHOUSTON, eTexas (KTRK) — Ukuchitheka kweekhemikhali kwiziko lemizi-mveliso eLa Porte kubulale abantu ababini kwaza kwenzakalisa abantu abaninzi ngoLwesibini ebusuku. Le khemikhali ineendlela ezahlukeneyo zokusetyenziswa, kuquka nokusetyenziswa ngabantu. Kodwa xa ikwimo yayo ecocekileyo, inokuba yingozi, itsha kwaye ibulale.
Ingozi eyenzeka kwisakhiwo saseLyondellBasell ikhuphe malunga neekhilogram ezili-100,000 ze-acetic acid, nto leyo ebangele ukutsha kunye neengxaki zokuphefumla kwabasindileyo.
I-acetic acid lulwelo olungenambala, i-organic compound enevumba elimnandi esetyenziswa ekwenzeni iipeyinti, izitywini, kunye nezincamathelisi. Ikwayeyona nto iphambili kwiviniga, nangona uxinaniso lwayo lumalunga ne-4–8% kuphela.
Ngokweengxelo ezikwiwebhusayithi kaLyondellBasell, ivelisa ubuncinane iintlobo ezimbini ze-glacial acetic acid. Ezi mveliso zichazwa njenge-anhydrous.
Ngokwephepha ledatha yokhuseleko lenkampani, le khemikhali inokutsha kwaye ingenza umphunga oqhumayo kumaqondo obushushu angaphezu kwama-102 degrees Fahrenheit (39 degrees Celsius).
Ukudibana ne-glacial acetic acid kunokubangela ukurhawuzelelwa emehlweni, elukhumbeni, empumlweni, emqaleni, nasemlonyeni. I-American Chemistry Council ithi ubuninzi bale khemikhali bunokubangela ukutsha.
Umgangatho ophantsi wokuvezwa omiselwe yi-Occupational Safety and Health Administration yi-10 parts per million (ppm) kwixesha leeyure ezisibhozo.
IZiko loLawulo lweZifo licebisa ukuba ukuba uchaphazeleke yintsholongwane, kufuneka ufumane umoya omtsha ngoko nangoko, ukhulule zonke iimpahla ezingcolisiweyo, kwaye uhlambe indawo engcolisiweyo ngamanzi amaninzi.
