Kodi Kununkhira kwa Sodium Cyanide Ndikoopsa?

Sodium cyanide ndi pawiri poizoni kwambiri ntchito njira zosiyanasiyana mafakitale, kuphatikizapo migodi golide, electroplating, ndi kaphatikizidwe mankhwala. Mukakumana ndi chinyezi kapena acid, sodium cyanide akhoza kumasula hydrogen cyanide mpweya, amene ali osiyana chowawa amondi - ngati fungo. Funso loti ngati fungo la Sodium Cyanide Choyipa ndi chofunikira kwambiri, chifukwa chimaphatikizapo kumvetsetsa mtundu ndi machitidwe a chinthu chowopsachi.

Kuopsa kwa Hydrogen Cyanide

Fungo logwirizana ndi Sodium cyanide zimachitika makamaka chifukwa cha kutulutsa mpweya wa hydrogen cyanide. Hydrogen cyanide ndi mpweya wapoizoni kwambiri womwe umatha kulowa mwachangu m'thupi kudzera pakukoka mpweya, kumeza, kapena kuyamwa pakhungu. Akalowa m'thupi, haidrojeni cyanide imamangiriza ku cytochrome oxidase m'maselo, ndikusokoneza kupuma kwabwino kwa ma cell. Izi zimalepheretsa maselo kuti asagwiritse ntchito mpweya wabwino, zomwe zimapangitsa kuti pakhale zovuta zambiri zaumoyo.

Kuwonetsa ngakhale kuchepa kwa hydrogen cyanide kungayambitse zizindikiro monga mutu, chizungulire, nseru, kusanza, kupuma mofulumira, ndi chisokonezo. Kuchulukirachulukira kungayambitse zizindikiro zazikulu, kuphatikizapo kukomoka, kukomoka, kulephera kupuma, ndipo pamapeto pake imfa. Kununkhira kwa hydrogen cyanide kumasiyanasiyana pakati pa anthu, ndipo anthu ena sangathe kuzindikira konse fungo la amondi, zomwe zimapangitsa kudalira fungo lokhalo kuti liwoneke kukhala loopsa kwambiri.

Njira Zowonetsera

Kukoka mpweya ndiyo njira yodziwika kwambiri komanso yowopsa yofikira ku hydrogen cyanide yotulutsidwa kuchokera ku sodium cyanide. M'mafakitale momwe sodium cyanide imagwiritsidwa ntchito, mpweya wosakwanira kapena kutayika mwangozi kungayambitse kutulutsa mpweya wochuluka wa hydrogen cyanide mumlengalenga. Ngakhale kachulukidwe kakang'ono ka sodium cyanide kakuchita ndi madzi kapena asidi mu malo otsekedwa amatha kupanga malo owopsa.

Kukhudzana pakhungu ndi sodium cyanide kapena mankhwala omwe ali nawo kungakhale kowopsa. Sodium cyanide imatha kuyamwa kudzera pakhungu, ndipo ngati khungu lanyowa kapena lonyowa, kuchuluka kwa mayamwidwe kumawonjezeka. Izi zingayambitse poizoni wa systemic, monga cyanide imalowa m'magazi ndipo imakhudza ziwalo zosiyanasiyana. Kulowetsedwa kwa sodium cyanide, ngakhale kuti sikofala kwambiri pazochitika zosadzipha, kumatha kuchitika ngati njira zotetezera sizitsatiridwa, mwachitsanzo, ngati chakudya kapena zakumwa zaipitsidwa ndi sodium cyanide m'mafakitale kapena labotale.

Chitetezo

Poganizira kuopsa kwa sodium cyanide ndi mpweya wa hydrogen cyanide, chitetezo champhamvu chiyenera kutengedwa pogwira mankhwalawa. Ogwira ntchito m'mafakitale omwe amagwiritsa ntchito sodium cyanide ayenera kuphunzitsidwa njira zoyenera zogwirira ntchito, kuphatikiza kuvala zida zodzitetezera (PPE). Izi zikuphatikizapo gasi - suti zothina, zida zopumira zokha (SCBA), ndi magolovesi oletsa kutulutsa mpweya, kukhudzana ndi khungu, ndi kuyamwa.

Kuonjezera apo, malo ogwirira ntchito omwe sodium cyanide amagwiritsidwa ntchito ayenera kukhala ndi mpweya wabwino kwambiri kuti achotse mwamsanga mpweya uliwonse wa hydrogen cyanide. Ndondomeko zoyankhira zadzidzidzi ziyenera kukhazikitsidwa, kuphatikiza njira zotulutsira malowo ngati kutayikira kapena kutayikira, komanso kupereka chithandizo chamankhwala mwachangu kwa anthu omwe ali pachiwopsezo. Malo opangira ma laboratories ndi mafakitale ayeneranso kukhala ndi malo oyenera osungiramo sodium cyanide, kuonetsetsa kuti imasungidwa kutali ndi magwero a chinyezi ndi zidulo kuti asatulutse hydrogen cyanide.

Kutsiliza

Pomaliza, fungo la sodium cyanide ndilovulazadi, chifukwa limasonyeza kutulutsidwa kwa mpweya wapoizoni wa hydrogen cyanide. Kuwonetsedwa ndi hydrogen cyanide kumatha kukhala ndi zotsatira zoyipa komanso zowopsa paumoyo wamunthu. Kaya m'mafakitale, labotale, kapena malo ena aliwonse omwe sodium cyanide ingakhalepo, ndikofunikira kudziwa kuopsa kwake ndikuchita zonse zofunikira zotetezera kuti musamawonekere. Ngati mukukayikira kuti muli ndi sodium cyanide kapena hydrogen cyanide, pitani kuchipatala mwamsanga ndipo tulukani m'deralo kuti musavulazenso.
