Imithetho Ye-sodium Cyanide Nokuhambisana

Isingeniso

Sodium i-cyanide iyikhemikhali enobuthi kakhulu futhi eyingozi. Ngenxa yengozi yayo enkulu, eqinile Imithetho nemigomo zisungulwe emhlabeni jikelele ukuphatha ukukhiqizwa, ukugcinwa, ukuthutha, ukusetshenziswa, nokulahlwa kwayo. Ukuqinisekisa Compliance ngale mithethonqubo ibaluleke kakhulu hhayi ekuvikelweni kwemvelo kuphela kodwa nasekuvikelekeni komphakathi. Lesi sihloko sicubungula imithetho nemigomo ehlukahlukene ehlobene I-sodium cyanide futhi ihlola izici zokuthobela.

Imithetho Nezimiso Ezilawula I-Sodium Cyanide

Imithetho Yamazwe Ngamazwe

1.Ingqungquthela yaseRotterdam

• Lesi sivumelwano samazwe ngamazwe sigxile enqubweni yemvume enolwazi kusengaphambili yamakhemikhali athile ayingozi nezibulala-zinambuzane ekuhwebeni kwamazwe ngamazwe. Nakuba I-Sodium Cyanide angeke ifakwe ohlwini ngokuqondile ngaphansi kwezinto eziwumongo zeSivumelwano Sase-Rotterdam, ukuhweba nokunyakaza kwayo kuthintwa ngokungaqondile uhlaka lulonke lokulawulwa kwamakhemikhali ayingozi. Umhlangano uhlose ukuqinisekisa ukuthi amazwe ayazi ngezingozi ezingaba khona ezihlobene namakhemikhali awathenga kwamanye amazwe, okunomthelela ekweqa imingcele i-sodium cyanide.

2.IsiVumelwano saseStockholm Sokungcolisa Okuqhubekayo Kwezinto Eziphilayo

• Nakuba i-sodium cyanide ingeyona into ephikelelayo engcolisa izinto eziphilayo, izimiso ezivamile zokuvikela imvelo kanye nokunciphisa ubungozi ezishiwo kulo mhlangano zithonya indlela yokulawula izinto ezinobuthi obuphezulu njenge-sodium cyanide. Ukugcizelela kwengqungquthela ekunciphiseni ukukhishwa kwezinto eziyingozi endaweni kunomthelela wokuchitheka - phezu kokuthi i-sodium cyanide ilawulwa kanjani mayelana nokugcinwa nokulahlwa ukuze kuvinjelwe ukungcoliswa kwemvelo.

Imithetho Kazwelonke - Yezinga e-United States

1.I-Toxic Substances Control Act (TSCA)

• I-TSCA inika i-US Environmental Protection Agency (EPA) igunya lokulawula ukukhiqizwa, ukungenisa, ukusetshenziswa, kanye nokulahlwa kwezinto zamakhemikhali, okuhlanganisa i-sodium cyanide. Abakhiqizi nabangenisi be-sodium cyanide kudingeka babike ulwazi oluningiliziwe mayelana nekhemikhali, njengevolumu yokukhiqiza, ukusetshenziswa okuhlosiwe, kanye nemiphumela engaba khona yezempilo nemvelo. Lokhu kusiza i-EPA ukuthi ihlole futhi ilawule izingozi ezihlobene ne-sodium cyanide.

2. Umthetho Wokongiwa Kwezinsiza kanye Nokubuyisela (RCRA)

• Lapho i-sodium cyanide iba udoti, i-RCRA iqala ukusebenza. Ihlukanisa imfucuza eyingozi futhi ibeke izindinganiso zokuphathwa kwayo, okuhlanganisa ukugcinwa, ukuthutha, nokulahlwa. Imfucuza ye-sodium cyanide kumele isingathwe ngokuhambisana ne-RCRA - izinqubo ezishiwo ukuvimbela ukungcoliswa kwemvelo nokuvikela impilo yabantu. Isibonelo, izixazululo ze-cyanide ezingcolile kufanele ziphathwe ukuze kukhishwe ubuthi be-cyanide ngaphambi kokulahlwa.

Imithetho ku-European Union

1.Ukubhaliswa, Ukuhlola, Ukugunyazwa, kanye Nokukhawulelwa Kwamakhemikhali (REACH)

• I-REACH idinga izinkampani ukuthi zibhalise izinto zamakhemikhali ezizenzayo noma zingenise e-EU. Nge-sodium cyanide, izinkampani kufanele zinikeze ulwazi olubanzi mayelana nezakhiwo zayo, ukusetshenziswa, nezinyathelo zokuphepha. Lokhu kwenza i-EU iqonde kangcono izingozi ezihlobene ne-sodium cyanide futhi ithathe izinyathelo ezifanele zokulawula. Inqubo yokuhlola ngaphansi kwe-REACH ingase iholele emikhawulweni yokusetshenziswa okuthile kwe-sodium cyanide uma ubungozi buthathwa njengobungamukelekile.

2.Iziqondiso Ezintweni Eziyingozi Namalungiselelo

• Lezi ziqondiso, njenge-Dangerous Substances Directive (67/548/EEC) kanye ne-Dangerous Preparations Directive (1999/45/EC), zihlukanisa i-sodium cyanide njengento eyingozi kakhulu. Babeka izimfuneko zokulebula, ukupakishwa, kanye namaphepha edatha yokuphepha. Lokhu kuqinisekisa ukuthi abasebenzi nabathengi bayazazi izingozi ezihlobene ne-sodium cyanide futhi bangathatha izinyathelo zokuphepha ezifanele.

Ukucatshangelwa kokuhambisana

Izikhungo Zokukhiqiza

1.Izinyathelo Zokuphepha Nokuqeqeshwa

• Izikhungo zokukhiqiza eziphethe i-sodium cyanide kumele zisebenzise izinyathelo zokuphepha eziqinile. Lokhu kubandakanya ukufaka ukuvuza - amasistimu okubona, umoya ofanele, kanye nemishini yokusabela ezimweni eziphuthumayo. Abasebenzi abathintekayo ohlelweni lokukhiqiza kufanele bathole ukuqeqeshwa okuphelele mayelana nokuphatha i-sodium cyanide, okuhlanganisa nezinqubo zokuphepha, usizo lokuqala uma kwenzeka bechayeka, kanye nezinqubo zokubhekana nezimo eziphuthumayo. Ukuthobela lezi zidingo akunciphisi nje kuphela ingozi yezingozi kodwa futhi kuhlangabezana nezibopho ezingokomthetho.

2.Ukuvikelwa Kwemvelo

• Izakhiwo zokukhiqiza zidinga ukuqinisekisa ukuthi akukho kukhishwa kwe-sodium cyanide endaweni ezungezile. Lokhu kungase kuhlanganise ukusetshenziswa kobuchwepheshe obuthuthukisiwe bokulawula ukungcoliswa komhlaba, njengezikhuhla ukuze zithwebule noma yimaphi amagesi e-cyanide - aqukethe. Ukuqapha kwemvelo okuvamile nakho kuyadingeka ukuze kuboniswe ukuhambisana nemithetho yemvelo. Isibonelo, ukuqapha amazinga e-cyanide emanzini angcolile akhishwa endaweni yokukhiqiza ukuze kuqinisekiswe ukuthi angaphakathi kwemikhawulo evunyelwe.

Isitoreji Nezokuthutha

1.Izimfuneko Zesitoreji

• I-sodium cyanide kumele igcinwe ezindaweni ezivikelekile, ezinomoya okahle ezenzelwe ukuvikela ukuvuza nokuchitheka. Iziqukathi zokugcina kufanele zenziwe ngezinto ezikwazi ukumelana nokugqwala nge-sodium cyanide. Ukwengeza, izindawo zokugcina kufanele zimakwe ngokucacile njengeziqukethe izinto eziyingozi, futhi ukufinyelela kufanele kukhawulelwe kubasebenzi abagunyaziwe kuphela. Ukuhambisana nalezi zidingo zokulondoloza kubalulekile ukuze kuvinjelwe ukukhishwa ngephutha kwe-sodium cyanide.

2.Imithetho Yezokuthutha

• Ngesikhathi sokuthutha, i-sodium cyanide kufanele ihanjiswe ngokuhambisana nemithetho eqinile. Lokhu kuhlanganisa ukusetshenziswa kwezimoto zokuthutha ezigunyaziwe ezinezinhlelo zokuvikela ukuchitheka. Abashayeli balezi zimoto kumele baqeqeshelwe ukuphatha izinto eziyingozi futhi balandele imizila ethile ukuze banciphise ubungozi bokuchayeka emphakathini uma kwenzeka ingozi. Izidingo zokubhalwa kwemibhalo yokuthuthwa kwe-sodium cyanide, njengezikweletu zokulayisha kanye namaphepha edatha yokuphepha, kufanele nazo zihlangatshezwe.

Ukulahlwa Kwemfucumfucu ye-Sodium Cyanide

1.Izindlela Zokwelapha kanye Nokulahla

• Lapho i-sodium cyanide iba udoti, ayikwazi ukulahlwa endaweni evamile yokulahla imfucumfucu. Esikhundleni salokho, kufanele iphathwe ukuze ikhiphe ubuthi be-cyanide. Izindlela zokwelashwa ezijwayelekile zihlanganisa i-chemical oxidation, njengokusebenzisa i-hydrogen peroxide noma i-chlorine ukuze uhlukanise i-cyanide ibe izinto eziyingozi kancane. Ngemva kokwelashwa, udoti kufanele ulahlwe endaweni egunyaziwe yokulahla imfucuza eyingozi. Ukuhambisana nalezi zindlela zokulahla kubalulekile ukuze kuvinjelwe ukukhululwa kwe-cyanide enobuthi endaweni ezungezile.

2.Imibhalo kanye nokubika

• Izinsiza zokulahla imfucuza ye-sodium cyanide ziyadingeka ukuze kugcinwe amarekhodi anemininingwane yokuphathwa kwemfucuza kanye nenqubo yokulahla. Lokhu kuhlanganisa ulwazi ngenani lemfucuza, indlela yokwelapha esetshenzisiwe, nendawo yokulahla. Ukubika njalo kuziphathimandla ezifanele zezemvelo nakho kuyadingeka ukuze kuboniswe ukuhambisana nemithetho yokulawulwa kwemfucuza.

Imiphumela Yokungathobeli

Ukungathobeli imithetho nemithetho ehlobene ne-sodium cyanide kungaba nemiphumela emibi kakhulu. Endabeni yokwephulwa kwemvelo, izinkampani zingase zibhekane nezinhlawulo ezibalulekile. Ngokwesibonelo, e-United States, ukwephulwa kwe-RCRA kungase kubangele inhlawulo efinyelela ezigidini ezimbalwa zamaRandi ngosuku. Ngaphezu kwezinhlawulo zezezimali, ukungathobeli imithetho kungaholela ekuvalweni kwezikhungo, amacala obugebengu abhekiswe kubantu abanomthwalo wemfanelo, futhi kulimaze isithunzi senkampani. Ezimweni ezimbi kakhulu, ukungathobeli kungabangela izinhlekelele zemvelo futhi kufake engozini impilo yomphakathi, njengoba kubonakala kwezinye izingozi zomlando zezimboni ezibandakanya i-sodium cyanide.

Isiphetho

I-sodium cyanide iyikhemikhali edinga ukulawulwa okuqinile ngenxa yobuthi bayo obukhulu. Imithetho nemithetho yamazwe ngamazwe, kazwelonke, neyesifunda isisunguliwe ukuze kulawuleke zonke izici ze-sodium cyanide, kusukela ekukhiqizweni kuye ekulahleni. Ukuthobela le mithetho akusona nje isibopho esingokomthetho kodwa futhi kuwumthwalo wemfanelo wokuvikela imvelo nokuphepha komphakathi. Izinkampani nabantu abathintekayo ekuphatheni i-sodium cyanide kumele baqaphe ukuze baqinisekise ukuthi bahlangabezana nazo zonke izidingo zokulawula ukuze bagweme imiphumela emibi yokungathobeli imithetho. Njengoba ukuqonda kwethu izingozi ezihlobene ne-sodium cyanide kuguquka, imithetho ingase ithuthukiswe ngokwengeziwe, futhi imizamo yokuhambisana nayo izodinga ukuhambisana nesivinini.
