Kab lus no yuav muab cov lus qhia dav dav txog yuav ua li cas kom nyab xeeb thiab pov tseg cov ntim zoo li no.

Kev phom sij ntawm Cov Thawv Sodium Cyanide tso tseg

Sodium cyanide yog tshuaj lom heev. Txawm tias me me tuaj yeem ua rau tuag taus yog tias noj, nqus pa, lossis yog tias nws nkag mus rau ntawm daim tawv nqaij. Cov thawv tso tseg tej zaum tseem muaj cov seem seem sodium cyanide, uas tuaj yeem xau thaum lub sijhawm. Thaum twg Sodium cyanide los rau hauv kev sib cuag nrog dej los yog acids, nws muaj peev xwm tsim hydrogen cyanide gas, ib tug volatile thiab lom tshuaj lom heev. Cov pa roj no hnyav dua li huab cua thiab tuaj yeem khaws cia rau hauv qhov chaw qis qis, ua rau muaj kev phom sij rau cov neeg nyob ib puag ncig. Tsis tas li ntawd, yog tias cov seem ntawm sodium cyanide nkag mus rau hauv cov av lossis cov dej, nws tuaj yeem cuam tshuam rau ib puag ncig, ua rau muaj kev puas tsuaj rau ecosystems ntev thiab muaj peev xwm nkag mus rau cov khoom noj.

Kev Cai Ua Raws Cai

Ua ntej pib cov txheej txheem pov tseg, nws yog ib qho tseem ceeb kom paub txog thiab ua raws li tag nrho cov kev cai hauv zos, teb chaws, thiab thoob ntiaj teb. Cov cheeb tsam sib txawv muaj cov cai tshwj xeeb hais txog kev tuav thiab pov tseg cov pov tseg uas muaj kev phom sij, tshwj xeeb tshaj yog cov tshuaj lom xws li sodium cyanide. Cov kev cai no muaj xws li kev sau cov ntawv pov tseg kom raug, cov ntaub ntawv ntawm cov txheej txheem pov tseg, thiab kev siv cov chaw pov tseg uas tau tso cai. Kev tsis ua raws cai tuaj yeem ua rau muaj kev nplua hnyav, suav nrog kev nplua nyiaj ntau thiab kev lav phib xaub. Piv txwv li, nyob rau hauv lub tebchaws United States, lub Environmental Protection Agency (EPA) muaj cov kev cai nruj raws li Txoj Cai Tswj Kev Tiv Thaiv thiab Rov Qab Los (RCRA) uas tswj xyuas kev tswj cov khoom pov tseg, uas sodium cyanide - ntsig txog cov khib nyiab poob hauv qab.

Kauj ruam - los ntawm - Kauj Ruam Pov Tseg

1. Kev soj ntsuam thawj zaug

Ua ntej, pom qhov muag tshuaj xyuas lub thawv tso tseg. Tshawb xyuas cov cim qhia txog kev xau, corrosion, lossis puas. Yog tias pom cov dej xau, tsis txhob sim txav lub thawv yam tsis muaj kev ceev faj kom raug. Kos thaj tsam ib ncig ntawm lub thawv kom tiv thaiv kev nkag mus tsis tau.

Sim txiav txim kom muaj nuj nqis ntawm sodium cyanide seem hauv lub thawv. Cov ntaub ntawv no yuav muaj txiaj ntsig zoo rau cov kauj ruam pov tseg tom ntej, tshwj xeeb tshaj yog thaum xaiv txoj kev pov tseg uas tsim nyog thiab tus nqi ntawm cov tshuaj reagents xav tau rau kev kho mob (yog tias tsim nyog).

2. Ceev Faj Txog Kev Nyab Xeeb

Hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE). Qhov no suav nrog tshuaj - cov hnab looj tes tiv thaiv, lub cev tag nrho lub cev hazmat, tsom iav kev nyab xeeb, thiab lub tshuab ua pa nrog lub tshuab ua pa siab (HEPA) lim lossis cov roj tsim nyog - daim cartridge rau kev tiv thaiv cyanide.

Ua haujlwm nyob rau hauv qhov chaw uas muaj qhov cua, zoo dua sab nraum zoov lossis hauv lub hood fume yog tias muaj. Yog tias ua haujlwm sab nraum zoov, xaiv qhov chaw nyob deb ntawm thaj chaw muaj neeg nyob, qhov chaw dej, thiab cov kav dej.
