Ukuphathwa Okuphuthumayo Kwezingozi Zokuvuza Kwe-Sodium Cyanide

1. Isingeniso

Sodium i-cyanide iyinhlanganisela enobuthi kakhulu futhi esebenzayo. Uma kwenzeka a ukuvuza kwengozi, kungaba usongo olukhulu empilweni yabantu, endaweni ezungezile, nasezimpahleni. Ngakho-ke, kubalulekile ukuba kube nohlelo lokusabela ezimeni eziphuthumayo oluchazwe kahle futhi olusebenzayo ukuze kusingathwe izimo ezinjalo ngokushesha nangempumelelo.

2. Impendulo Esheshayo Ephuthumayo

2.1 Isaziso kanye ne-alamu

• Ngokushesha nje lapho a i-sodium cyanide ukuvuza kutholwa, isinyathelo sokuqala ukwazisa iziphathimandla ezifanele ngokushesha. Lokhu kuhlanganisa amaqembu endawo asabela ezimeni eziphuthumayo, izinhlangano ezivikela imvelo, nomnyango wezomlilo. Isistimu ye-alamu yangaphakathi kufanele futhi icushwe ngaphakathi kwendawo ukuze yazise bonke abasebenzi.

• Nikeza ulwazi olucacile nolunembile mayelana nendawo yokuvuza, inani elilinganiselwe le I-Sodium Cyanide abathintekayo, kanye nanoma yiziphi izingozi ezingaba khona njengemithombo yamanzi eseduze noma imithombo yokuthungela.

2.2 Ukukhipha

• Khipha bonke abasebenzi abangabalulekile endaweni ezungeze indawo yokuvuza. Misa i-perimeter ephephile ngokusekelwe ekusakazekeni okungenzeka kwento ewubuthi. Sebenzisa izikhulisa-zwi, izexwayiso zesimo esiphuthumayo, noma ezinye izindlela zokuxhumana ukuze uqondise abantu ezindaweni eziphephile ezimisiwe.

• Qinisekisa ukuthi abasebenzi bajwayelene nemizila yokuphuma kusenesikhathi ngokusebenzisa izivivinyo ezijwayelekile eziphuthumayo. Nikeza usizo kulabo abakhubazekile noma abanezidingo ezikhethekile phakathi nenqubo yokuphuma.

3. Ku-Site Ukusingatha Izinyathelo

3.1 Ukuqukethwe

• Sebenzisa izinto zokuvimbela ukuchitheka kwegazi ukuze uvimbele ukusabalala I-sodium cyanide. Lawa makhithi ngokuvamile aqukethe izinto ezimuncayo njenge-vermiculite, ubumba, noma amaphedi amuncayo akhethekile. Beka izinto ezimunca endaweni evuzayo ukuze ucwilise uketshezi noma uqukathe izinhlayiya eziqinile.

• Ngokuchitheka koketshezi, dala izithiyo usebenzisa amasaka esihlabathi noma ezinye izinto ezifanele ukuvimbela uketshezi olungcolile ukuthi lungagelezi emiseleni, ezindaweni zamanzi, noma kwezinye izindawo ezibucayi. Uma ukuvuza kwenzeka esakhiweni, vala iminyango namafasitela ukuze unciphise ukusabalala kwemfucuza.

3.2 Ukungathathi hlangothi

• Kwezinye izimo, ukungathathi hlangothi kwe-sodium cyanide kungenzeka. Isibonelo, lapho uphendula nge-hydrogen peroxide (H₂O₂), i-sodium cyanide ingaguqulwa ibe izinto eziyingozi kancane. Izibalo zokusabela zimi kanje:

• Lapho i-hydrogen peroxide intula: NaCN + H₂O₂ = NaCNO + H₂O

• Uma i-hydrogen peroxide yeqile: NaCN + H₂O₂ + H₂O = NaHCO₃+ NH₃

• Kodwa-ke, ukungathathi hlangothi kufanele kwenziwe kuphela ochwepheshe abaqeqeshiwe abanemishini yokuphepha efanele, njengoba ukusabela kungase kukhiqize ukushisa kanye nemikhiqizo engase ibe yingozi.

3.3 Ukuqoqwa nokulahlwa

• Ngemva kokubamba kanye nokunciphisa (uma kusebenza), qoqa ngokucophelela izinto ezimuncayo ezingcolile kanye nanoma iyiphi i-sodium cyanide esele. Zibeke ezitsheni ezivaliwe, ezibhalwe ukuthi eziklanyelwe udoti oyingozi.

• Hlela ukulahlwa okufanele kwezinto eziqoqiwe ngokusebenzisa izindawo ezigunyaziwe zokulahla imfucuza eyingozi. Qinisekisa ukuthi zonke izinqubo zokulahla zihambisana nemithetho yendawo, kazwelonke, kanye neyomhlaba jikelele yezemvelo.

4. Ukuvikelwa Kwabasebenzi

4.1 Izinto Zokuzivikela Zomuntu Siqu (PPE)

• Bonke abezimo eziphuthumayo kanye nabasebenzi abathintekayo ekusingatheni ukuvuza kufanele bagqoke i-PPE efanele. Lokhu kuhlanganisa amasudi amelana namakhemikhali, amagilavu, amabhuzu, ama-respirator agcwele ubuso anama-cartridge afanelekile okuvikela i-cyanide, nezibuko zokuphepha.

• I-PPE kufanele ihlolwe njalo futhi inakekelwe ukuze kuqinisekiswe ukusebenza kwayo. Abasebenzi kufanele futhi baqeqeshwe ukuthi banganikela kanjani futhi bayivale kahle i-PPE ukuze bagweme ukuzingcolisa.

4.2 Usizo Lokuqala kanye Nokuqapha Kwezempilo

• Yiba nethimba losizo lokuqala kokubekwe eceleni eduze nendawo evuzayo. Esimeni sokuchayeka kwe-cyanide, izinyathelo zosizo lokuqala kufanele zithathwe ngokushesha. Izimpawu zobuthi be-cyanide zihlanganisa ikhanda, isiyezi, ubuthakathaka, ukuphefumula ngokushesha, futhi ezimweni ezimbi kakhulu, ukulahlekelwa ukwazi nokufa.

• Uma umuntu echayeke ku-sodium cyanide, msuse endaweni engcolile umfake emoyeni omusha ngokushesha. Uma isikhumba singcolile, susa izingubo ezithintekile futhi ugeze isikhumba kahle ngamanzi okungenani imizuzu engu-15 - 20. Uma amehlo ethintekile, wageza ngamanzi amaningi. Nikeza umoya-mpilo uma ukuphefumula kunzima.

• Ukuqapha kwezokwelapha kwabasebenzi abavelile kufanele kuqhubeke isikhathi esifanele, njengoba eminye imiphumela yokuchayeka kwe-cyanide ingase ibambezeleke.

5. Ukuqapha Imvelo

5.1 Ukuqapha Umoya

• Sebenzisa okokusebenza okukhethekile okuhlonza igesi ukuqapha ukugcwala kwegesi ye-hydrogen cyanide (HCN) emoyeni. I-HCN igesi enobuthi obukhulu engakhululwa lapho i-sodium cyanide ihlangana nama-asidi noma ezimweni ezithile zemvelo.

• Hlala uqapha ikhwalithi yomoya ngaphakathi naseduze kwendawo okuvuzayo, futhi ubeke imikhawulo yokuchayeka ephephile. Uma ukugxiliswa kwe-HCN kweqa imikhawulo ephephile, thatha izinyathelo ezengeziwe ezifana nokwandisa umoya wokungenisa umoya noma ukukhipha ngokuqhubekayo indawo.

5.2 Ukuqapha Amanzi

• Uma ukuvuza kunamandla okungcolisa imithombo yamanzi, njengemifula eseduze, amachibi, noma amanzi angaphansi komhlaba, misa iziteshi zokuqapha amanzi. Hlola amanzi ukuze uthole ukugcwala kwe-cyanide ngezikhathi ezithile.

• Ukuqalisa izinyathelo zokuvimbela amanzi angcolile ukuthi angangeni ohlelweni lokuphakelwa kwamanzi. Lokhu kungase kuhlanganise ukuvala umthamo wamanzi, ukuphambukisa ukugeleza kwamanzi angcolile, noma ukuhlanza amanzi ukuze kukhishwe i-cyanide ngaphambi kokuba afinyelele emanzini.

6. Okuthunyelwe - Ukulandelela Ingozi - Up

6.1 Uphenyo

• Yenza uphenyo olunzulu ngembangela yengozi yokuvuza kwe-sodium cyanide. Lokhu kuhlanganisa ukuhlola ukugcinwa, ukuphatha, nezinqubo zokuthutha ze-sodium cyanide ukuze kutholakale noma yikuphi ukusilela noma ukwephulwa kwemithetho yezokuphepha.

• Imiphumela yophenyo kufanele isetshenziselwe ukuthuthukisa izinqubo zokuphepha futhi kuvinjwe izingozi ezifanayo ukuthi zenzeke esikhathini esizayo.

6.2 Ukubuyiselwa Kwemvelo

• Uma indawo ezungezile ingcoliswe i-sodium cyanide, thuthukisa futhi usebenzise uhlelo lokubuyisela imvelo. Lokhu kungase kuhlanganise ukulungiswa kwenhlabathi, ukugezwa kwamanzi, nokubuyiselwa kwezimiso zemvelo ezithintekile.

• Ukuqapha inqubekelaphambili yokubuyiselwa kwemvelo ukuqinisekisa ukuthi indawo ethintekile ibuyela esimweni esiphephile nesamukelekayo.

Ekuphetheni, i ukuphathwa kwezimo eziphuthumayo yezingozi zokuvuza kwe-sodium cyanide kudinga umzamo ohlangene ovela ezinhlangothini eziningi, ukubambelela ngokuqinile ezinkambisweni zokuphepha, nokuqapha okuqhubekayo ukuze kuncishiswe umthelela empilweni yomuntu kanye nemvelo.
