I-Ethylene oxideiyinhlanganisela yemvelo enefomula yamakhemikhali ye-C2H4O, okuyigesi yokwenziwa evuthayo. Uma ukugxila kwayo kuphezulu kakhulu, izokhipha ukunambitheka okumnandi.I-Ethylene oxideincibilika kalula emanzini, futhi inani elincane le-ethylene oxide lizokhiqizwa lapho kushiswa ugwayi. Inani elincanei-ethylene oxideingatholakala emvelweni.

I-ethylene oxide isetshenziswa kakhulu ukwenza i-ethylene glycol, ikhemikhali esetshenziselwa ukwenza i-antifreeze ne-polyester. Ingasetshenziswa futhi ezibhedlela nasezikhungweni zokubulala amagciwane ukuze kubulawe amagciwane imishini yezokwelapha kanye nempahla; Iphinde isetshenziselwe ukubulala amagciwane ekudleni nasekulawuleni izinambuzane emikhiqizweni ethile yezolimo egciniwe (njengezinongo namakhambi).

I-ethylene oxide iyithinta kanjani impilo

Ukuchayeka kwesikhashana kwabasebenzi ekugxilweni okuphezulu kwei-ethylene oxideemoyeni (ngokuvamile izikhathi ezingamashumi ezinkulungwane zezikhathi zabantu abavamile) kuzoshukumisa amaphaphu. Abasebenzi abachayeke ekugxilweni okuphezulu kwei-ethylene oxideisikhathi esifushane futhi eside angase aphathwe ikhanda, ukulahlekelwa inkumbulo, ukuba ndikindiki, isicanucanu nokuhlanza.

Ucwaningo luye lwathola ukuthi abesifazane abakhulelwe bavezwa ekugxilweni okuphezulu kwei-ethylene oxideemsebenzini kuzodala ukuthi abanye besifazane baphuphunyelwe yizisu. Olunye ucwaningo alutholanga umphumela onjalo. Ucwaningo olwengeziwe luyadingeka ukuze kuqondwe ubungozi bokuchayeka ngesikhathi sokukhulelwa.

Ezinye izilwane zihogela umoyai-ethylene oxidengokugxila okuphezulu kakhulu emvelweni (izikhathi eziyi-10000 eziphakeme kunomoya ovamile wangaphandle) isikhathi eside (izinyanga kuya eminyakeni), okuzoshukumisa ikhala, umlomo namaphaphu; Kukhona nemiphumela yemizwa nentuthuko, kanye nezinkinga zokuzala zabesilisa. Ezinye izilwane ezahogela i-ethylene oxide izinyanga ezimbalwa nazo zaba nesifo sezinso kanye ne-anemia (ukuncipha kwamangqamuzana abomvu egazi).

Angakanani amathuba okuthi i-ethylene oxide ibangele umdlavuza

Abasebenzi abachayeka kakhulu, abanesikhathi sokuchayeka esiphakathi kweminyaka eyi-10, basengozini enkulu yokuphathwa izinhlobo ezithile zomdlavuza, njengomdlavuza wegazi nomdlavuza webele. Umdlavuza ofanayo nawo utholakale ocwaningweni lwezilwane. UMnyango Wezempilo Nezinkonzo Zabantu (DHHS) ukunqumile lokhoi-ethylene oxideiyi-carcinogen eyaziwayo yomuntu. I-US Environmental Protection Agency isiphethe ngokuthi ukuhogela i-ethylene oxide kunemiphumela edala umdlavuza kubantu.

Indlela yokunciphisa ingozi yokuchayeka ku-ethylene oxide

Abasebenzi bazogqoka izibuko zokuzivikela, izingubo kanye namagilavu ​​lapho besebenzisa noma benzai-ethylene oxide, futhi ugqoke izinto zokuzivikela eziphefumulayo uma kudingeka.
