Impendulo Ephuthumayo Ezingozini Zokuvuza Kwe-Sodium Cyanide

Isingeniso

Sodium i-cyanide ikhemikhali enobuthi kakhulu esetshenziswa kabanzi ezimbonini ezifana ne-metallurgy, i-electroplating, nezimayini zegolide. Kodwa-ke, ngenxa yobuthi bayo obukhulu, noma yikuphi ukuvuza kwe i-sodium cyanide kungaba usongo olukhulu empilweni yomuntu nasendaweni ezungezile. Ngakho-ke, kubalulekile ukuba nencazelo ecacile futhi ephumelelayo impendulo ephuthumayo hlela izigameko ezinjalo.

Izakhiwo Nezingozi Ze-Sodium Cyanide

I-sodium cyanide (NaCN) iyikristalu eqinile emhlophe. Incibilika kakhulu emanzini futhi ingakhulula igesi ye-hydrogen cyanide (HCN) lapho kukhona ama-asidi noma ngaphansi kwezimo ezithile zemvelo. IHydrogen cyanide iyigesi eguquguqukayo futhi enobuthi ngokwedlulele enesici esibabayo - iphunga le-alimondi (yize kungeyena wonke umuntu ongalizwa leli phunga).

Ukuchayeka ku I-Sodium Cyanide kungenzeka ngokuhogela, ukumunca, noma ukuthinta isikhumba. Ukuhogela igesi ye-hydrogen cyanide kungabangela izimpawu ngokushesha, okuhlanganisa isiyezi, ikhanda elibuhlungu, ukuphelelwa umoya, ukucinana kwesifuba, isicanucanu, ukuhlanza, futhi ezimweni ezimbi kakhulu, kungaholela ekulahlekelweni ukwazi, ukuquleka, nokufa. Ukungeniswa kwe I-sodium cyanide kungase futhi kubulale, futhi ukuthintana kwesikhumba kungase kubangele ukucasuka nokumuncwa kwento enobuthi emzimbeni.

Izinqubo Eziphuthumayo Zokusabela

1. Ukutholwa Kokuqala Nokubika

• Isaziso Esisheshayo: Ngokushesha nje lapho kusolwa ukuvuza kwe-sodium cyanide noma kutholwa, izisebenzi zokuqala endaweni yesehlakalo kufanele zibike ngokushesha isigameko emaqenjini afanele angaphakathi ezimo eziphuthumayo, njengomnyango wezokuphepha wesikhungo, kanye neziphathimandla zangaphandle, okuhlanganisa iminyango yendawo yokucima umlilo, izikhungo zokuvikela imvelo, namahhovisi okuphatha izimo eziphuthumayo. Nikeza ulwazi oluningiliziwe mayelana nendawo yokuvuza, inani elilinganiselwe le-sodium cyanide elihilelekile, nanoma yiziphi izimpawu ezibonakalayo zokulimala noma izingozi ezingaba khona.

• Ukuhlola Izingozi: Ochwepheshe abaqeqeshiwe kufanele benze ngokushesha ukuhlolwa kwengozi kokuqala. Lokhu kuhlanganisa ukunquma ukusabalala okungenzeka kwe-sodium cyanide evuzayo, amathuba okukhishwa kwegesi (uma izimo zivumela ukwakheka kwe-hydrogen cyanide), kanye nomthelela ongaba khona kubantu abaseduze, imithombo yamanzi, nezindawo ezibucayi zemvelo.

2. Ukuphuma kanye Nokuhlukaniswa

Sebenzisa amasistimu amakheli omphakathi, ama-alamu, nezimpawu ezibonakalayo ukuze uxwayise abantu. Nikeza usizo kulabo abakhubazekile noma abanezidingo ezikhethekile phakathi nenqubo yokuphuma.

• Ukuhlukaniswa Kwendawo: Misa umjikelezo ozungeze indawo yokuvuza ukuze uvimbele ukungena okungagunyaziwe. Usayizi wendawo yokuhlukanisa kufanele unqunywe ngokusekelwe kuzinto ezifana nenani le-sodium cyanide elivuzile, indawo, kanye nendawo yomoya. Thumela izimpawu nezithiyo ukuze umake ngokucacile indawo ekhawulelwe.

3. Izinto Zokuzivikela Zomuntu Siqu (i-PPE) Zabaphenduli

• Ukuvikelwa kokuphefumula: Abaphendulayo abangena endaweni engcolile kufanele bagqoke ukuvikeleka okufanele kokuphefumula. Lokhu kungase kuhlanganise izisetshenziswa zokuphefumula eziqukethwe ngokwazo (SCBA) ezimweni lapho kunobungozi obukhulu bokuhogela igesi ye-hydrogen cyanide. Ezimweni ezimbi kakhulu lapho ukugcwala kokungcola okuphuma emoyeni kuphansi, ama-respirator ahlanza umoya anama-cartridges afanelekile (aklanyelwe ukuhlunga ama-cyanide compounds) angasetshenziswa, kodwa kuphela ngemva kokuhlolwa kobungozi okufanele.

• Ukuvikelwa Komzimba: Gqoka amasudi amelana namakhemikhali amboza umzimba wonke, okuhlanganisa amagilavu, amabhuzu, nehood. Lawa masudi kufanele angangeneli ku-sodium cyanide kanye nanoma yimiphi imikhiqizo ehlobene nokusabela kwamakhemikhali. Qinisekisa ukuthi i-PPE ifakwe kahle futhi isesimweni esihle ngaphambi kokusetshenziswa.

4. Ukuquleka kokuvuza

• Ukuvuza Okuncane: Ngokuvuza okuncane kwe-sodium cyanide, izinto ezimuncayo ezifana nokusebenza I-Carbon, i-vermiculite, noma isihlabathi kungasetshenziswa ukumunca into echithekile. Khupha into emuncwe bese uyibeka ezitsheni ezivaliwe, ezinelebula ukuze ilahlwe kahle. Geza indawo ethintekile ngamanzi amaningi, uqaphela ukuvimbela amanzi ukuthi angangeni emifuleni yamanzi noma ezinhlelweni zokuhambisa indle.

• Ukuvuza Okukhulu: Endabeni yokuvuza okukhulu, kufanele kwenziwe imizamo yokuqukatha i-sodium cyanide kusetshenziswa izithiyo ezibonakalayo. Lokhu kungase kuhlanganise ukwakha amadikhi noma ukusebenzisa ama-boom amunca ukuvimbela ukusabalala kwe-sodium cyanide ewuketshezi. Uma ukuvuza kwenzeke eduze nomthombo wamanzi, cabanga ukusebenzisa amadamu aphefumulayo noma ezinye izindlela zokuphambukisa ukugeleza kwamanzi angcolile kude nezindawo ezibucayi. Ungazami ukuhlanza ukuvuza okukhulu ngaphandle kokuqeqeshwa okufanele kanye nemishini. Linda ukufika kwamaqembu akhethekile okuphendula izinto eziyingozi.

5. Ukukhipha ukungcola

• Ukususa Ukungcola Kwabantu: Noma ubani oke wachayeka ku-sodium cyanide, ngokuthintana ngokuqondile noma ngokuba seduze nalapho kuvuza khona, kufanele akhishwe ukungcola. Susa zonke izingubo ezingcolile ngokushesha futhi uzifake ezikhwameni zepulasitiki ezivaliwe. Geza umzimba kahle ngamanzi amaningi okungenani imizuzu engu-15, unake ngokukhethekile izindawo ezinjengobuso, izandla, nanoma imaphi amanxeba avulekile. Uma amehlo evuliwe, nisela ngamanzi ahlanzekile okungenani imizuzu eyi-15. Nikeza usizo lwezokwelapha kubantu abadaluliwe ngokushesha ngangokunokwenzeka.

• Ukususwa kokungcola Kwendawo: Ngemuva kokuthi ukuvuza sekuqediwe, indawo engcolile idinga ukungcoliswa. Lokhu kungase kuhlanganise ukugeza phansi izindawo ngesixazululo se-bleach (i-sodium hypochlorite) namanzi. Isilinganiso se-bleach namanzi kufanele sinqunywe ngokusekelwe kubukhulu bokungcoliswa kanye nokulandela imihlahlandlela yokuphepha efanele. Inqubo yokususa ukungcola kufanele yenziwe ngabasebenzi abaqeqeshiwe abagqoke i-PPE efanele.

6. Ukwelashwa Kwabantu Abadaluliwe

• Usizo Lokuqala ku-Site: Nikeza usizo lokuqala olusheshayo kulabo abaye bachayeka ku-sodium cyanide. Hlola izimpawu zokuphefumula nokushaya kwenhliziyo. Uma isisulu singaphefumuli, qalisa i-cardiopulmonary resuscitation (CPR) ngokushesha. Lawula i-oxygen uma ikhona. Ungalibali ukuthutha isisulu usiyise esikhungweni sezokwelapha.

• Ukwelashwa Ngezokwelapha: Esikhungweni sezokwelapha, iziguli zingase zelashwe ngezinqamuleli ezithile zobuthi be-cyanide, njenge-hydroxocobalamin noma izinhlanganisela ze-sodium nitrite/sodium thiosulfate. Ukukhethwa kwekhambi kuncike ebubini bokuchayeka kanye nesimo sesiguli. Okunye ukwelashwa okusekelayo, okunjengoketshezi olufakwa emthanjeni, ukulawula ukuquleka, nokulungiswa kwe-metabolic acidosis, nakho kungadingeka.

7. Ukuqapha Imvelo

• Air Monitoring: Ngokuqhubekayo uqaphe izinga lomoya endaweni ethintekile nasezizungezile ukuze uthole ukuba khona kwegesi ye-hydrogen cyanide. Sebenzisa izitholi zegesi eziphathwayo ukukala ukugcwala kwegesi ezindaweni ezihlukene nangezikhathi ezithile. Misa iziteshi zokuqapha ezingaguquki uma kunesidingo ukuze ulandelele ukusakazeka kwesikhathi eside kwegesi.

• Ukuqapha Amanzi: Uma ukuvuza kwe-sodium cyanide kunamandla okungcolisa imithombo yamanzi, qapha ikhwalithi yamanzi ezansi nomfula wendawo evuzayo. Hlola ukuba khona kwama-ion e-cyanide emanzini angaphezulu, emanzini angaphansi komhlaba, nanoma imaphi amanzi asetshenziselwa ukuphuza noma ezinye izinjongo ezibalulekile. Ukusebenzisana nezindawo zokuhlanza amanzi ukuze uqinisekise ukuthi kuthathwa izinyathelo ezifanele zokususa i-cyanide emanzini uma ithintekile.

8. Ukulahlwa Kwezinto Ezingcolile

• Imfucumfucu Eqinile: Izinto ezimunca izinto ezingcolile, i-PPE esetshenzisiwe, nanoma yiziphi ezinye izinto eziqinile ezihlangane ne-sodium cyanide kufanele zifakwe ezitsheni ezivaliwe, ezibhalwe phansi. Lezi zitsha kufanele zithuthwe ziyiswe endaweni enelayisensi yokulahla imfucuza eyingozi ukuze ziphathwe kahle futhi zilahlwe.

• Udoti Owuketshezi: Noma iyiphi imfucumfucu ewuketshezi ekhiqizwa ngesikhathi sokuhlanza, njengamanzi angcolile asuka ekungcolisweni noma agelezayo endaweni okuvuza kuyo, kufanele aqoqwe futhi alashwe. Izindlela zokwelapha zingabandakanya i-chemical oxidation (isb., ukusebenzisa i-hydrogen peroxide noma i-chlorine - oxidants esekelwe) ukuze kuhlukaniswe izinhlanganisela ze-cyanide zibe izinto eziyingozi kakhulu. Uma esekhishiwe, amanzi kufanele ahlolwe ukuze kuqinisekiswe ukuthi amazinga e-cyanide angaphakathi kwemingcele eyamukelekayo yemvelo ngaphambi kokuba akhishwe.

Ukuhlolwa kwesigameko

Ngemuva kokuthi impendulo ephuthumayo yokuvuza kwe-sodium cyanide isiqediwe, yenza ukuhlolwa okuphelele kwesigameko. Lokhu kuhlola kufanele kubandakanye ukuhlolwa kokusebenza ngempumelelo kohlelo lokubhekana nezimo eziphuthumayo, ukuhlonzwa kwanoma yikuphi ukushiyeka enqubweni yokusabela, nokunqunywa kwezindawo okufanele zenziwe ngcono.
