Kubata Kwakachengeteka kweYakanyanya Toxic Cyanides/ Sodium Cyanide

ziviso

MaCyanides, kunyanya Sodium Cyanide , zvinhu zvine chepfu zvakanyanya. Kusashandiswa zvakanaka kunogona kukonzera njodzi huru kuhutano, kusvibiswa kwezvakatipoteredza, uye kutoisa hupenyu panjodzi. Nokudaro, zvakakosha zvikuru kuva nekunzwisisa kwakadzama uye kutevedzera mitemo yekuchengetedza pakubata nemakemikari aya.

Chidziviriro Chekushandisa (PPE)

Kudzivirirwa kwekufema

Zvinodiwa kushandisa mudziyo wekufema wega (SCBA) une mask yekumeso yakazara. Zvichienderana nekuti maCyanides anogona kufemedzwa neguruva, utsi, kana gasi, chiyero ichi chakakosha zvikuru. SCBA inofanira kunge ine firita yemhepo ine simba repamusoro (HEPA) kudzivirira chero zvidimbu zvine cyanide kuti zvisapinde muhurongwa hwekufema.

Inodzivirira Kupfeka

Pfeka sutu isingapindi mishonga yakagadzirwa nezvinhu zvakaita seTyvek kana neoprene. Sutu yacho inofanira kufukidza muviri wese, kusanganisira maoko, tsoka, nemusoro. Zvinokurudzirwa kupfeka magirovhosi asingapindi mvura akagadzirwa nerabha yebutyl kudzivirira maoko. Bhutsu dzekuchengetedza dzine zvigunwe zvesimbi uye pasi dzisingapindi mishonga zvakakoshawo kudzivirira tsoka kuti dzisabate cyanides.

Kuchengetedzwa Kwameso

Pamusoro peiyo SCBA kumeso mask, makemikari - splash goggles anofanirwawo kuve akashongedzerwa. Aya magogi anogona kupa imwezve dura redziviriro kuvharira cyanide mhinduro kubva mukupfapfaidza mumaziso.

Kubata matanho ekudzivirira

chengetedzo

MaCyanides anofanira kuchengetwa munzvimbo yakatarwa uye ine mhepo yakanaka, kure nemhepo inodziya, maacid, uye zvinhu zvinooxidisa. MaCyanides anoita zvine simba nemaacids kuti abudise gasi rine chepfu rehydrogen cyanide. Magaba ekuchengetera anofanira kuvharwa zvakasimba uye kunyorwa zvakajeka nezita remakemikari, yambiro dzenjodzi, uye mirairo yekubata.

Kutamisa uye Kushandisa

Paunenge uchiendesa macyanides kubva kune imwe mudziyo uchienda kune imwe, shandisa akakosha funnels uye ekutamisa michina inoenderana necyanides. Kudira kwakananga nemaoko kunorambidzwa zvachose. Murabhoritari kana nharaunda yeindasitiri, mashandiro ese anosanganisira cyanides anofanirwa kuitwa mufume hood kudzivirira utsi hune chepfu kubva kupararira kunzvimbo yebasa rose.

Shandisa zvikero zvakayerwa kuyera kana midziyo yevhoriyamu kuyera nema cyanides. Dzivisa pamusoro-kuyera kana kuvuza, nekuti kunyange cyanide shoma shoma inogona kuunza njodzi huru.

Emergency Response Plan

kudzidza

Vashandi vese vanogona kusangana necyanides vanofanira kudzidziswa nezvenzira dzekupindura nekukurumidza . Zviri mukudzidziswa zvinosanganisira kuziva zviratidzo zvecyanide chepfu (zvakadai semusoro, dzungu, kufema nekukurumidza, kurasikirwa nepfungwa, nezvimwewo) uye kugona nzira dzekushandisa matanho ekubatsira kutanga.

Emergency Equipment

Imwe yekukurumidzira eyewash station uye yekugezera yekuchengetedza inofanira kupihwa munzvimbo yebasa. Kana ganda kana ziso richisangana ne cyanides, kukurumidza kubhururuka nemvura yakawanda ndiyo kiyi. Uye zvakare, yakakosha cyanide antidotes senge hydroxocobalamin, sodium nitrite, uye sodium thiosulfate inofanirwa kuiswa panzvimbo, asi inofanirwa kushandiswa pasi pekutungamirwa nenyanzvi dzekurapa.

Nzira dzakajeka dzekubuda uye nzira dzinofanirwa kugadzirwa. Muchiitiko chekudonhedza kana kuburitswa kwecyanide yakakura, vashandi vanofanirwa kuziva nzira yekubuda nayo munzvimbo nekukurumidza uye zvakachengeteka.

Kuraswa kweCyanides

Kemikari Kurapa

Imwe yedzakajairika nzira dzekurapa cyanide - ine tsvina ndeyemakemikari oxidation. Sodium hypochlorite (bleach) inogona kushandiswa kuita oxidize cyanides kuita zvinhu zvishoma zvine chepfu. Kuita uku kunofanira kunyatsodzorwa munzvimbo inofefetera zvakanaka. Iyo general reaction formula ndeyotevera:

2NaCN + 5NaClO + H₂O → N₂ + 2NaHCO₃ + 5NaCl

Imwe sarudzo ndeye kushandisa hydrogen peroxide pasi pechiito checatalyst. Iyi nzira inogona zvakare kushandura cyanides kuita isiri-chepfu zvigadzirwa.

Neutralization

Mushure mekurapa oxidation, mhinduro inogona kudikanwa kuderedzwa. Kana iyo yakagadziriswa mhinduro iine acidic nekuda kweiyo oxidation process, hwaro hwakadai sesodium hydroxide inogona kushandiswa kugadzirisa iyo pH kukosha kune kwayakarerekera renji (pH 6 - 9).

Compliance Disposal

Mushure mekunge ma cyanides arapwa uye akaderedzwa, tsvina inogadzirwa inofanirwa kuraswa zvinoenderana nenharaunda, yenyika, uye yemubatanidzwa mitemo yezvakatipoteredza. Izvi zvinowanzoreva kutumira marara kunzvimbo ine rezinesi yekurasa tsvina ine ngozi.

mhedziso

Kubata macyanides, kunyanya sodium cyanide , kunoda kungwarira kukuru uye kutevedzera mitemo yekuchengetedza. Kubva pakusarudza michina yekudzivirira yakakodzera, kugadzira hurongwa hwekupindura nekukurumidza , kusvika kune nzira dzakachengeteka dzekurasa, nhanho yega yega mukubata inofanira kufungwa nezvayo. Nekutevera nhungamiro idzi, tinogona kuderedza njodzi dzinosanganisirwa nezvinhu izvi zvine chepfu uye kuona kuti vashandi nenzvimbo zvakachengetedzeka vakachengeteka.
