Cov khoom siv ua haujlwm yooj yim txheej txheem ua haujlwm
1, kom tsis yooj yim rau cov khoom hluav taws tso rau hauv qhov chaw hluav taws thiab chaw sim.
2, yuav tsum tsis muaj qhov hluav taws kub hauv kev khaws cov khoom hluav taws uas nyob ib puag ncig; kev tiv thaiv roj (haus dej cawv) teeb, hlawv ntais ntawv thiab lwm yam;
3, kev siv cov sublimation hauv cov distillation lossis yooj yim rau hluav taws cov khoom yuav tsum tau sau tseg:
(1) tsis pub siv hluav taws qhib muaj cua sov, cua sov muaj dej (roj) da dej, hluav taws xob kub lossis hluav taws xob xuab zeb, muaj ib puag ncig uas tsis qhib nplaim taws;
(2) cov cuab yeej kuaj yuav tsum nruj airtight;
(3) hauv qab cov khoom siv khov kho, yuav tsum muaj lub tais hlau, (ntug qhov siab 80-100 hli);
(4) qhov chaw ua haujlwm yuav tsum muaj qhov cua zoo, ib puag ncig los ntawm cov khoom siv hluav taws xob tsis tuaj yeem tso tsis tau.
(5) ua haujlwm coj iav.
4, nyob rau hauv qhov chaw kuaj cia ntawm ntau cov khoom sib txuas pub tsis pub tshaj peb kilo, txhua qhov yuav tsum tsis pub tshaj ib kilo. Nrog rau siv nrog, nrog rau sab nraum qab rau qhov chaw ntim tshwj xeeb.
5, yooj yim rau hluav taws nrog cov tshuaj dej (xws li daj phosphorus, sodium peroxide, hlau sodium, poov tshuaj, thiab lwm yam) txwv tsis pub rau hauv lub thoob khib nyiab. Qhov twg tuaj yeem ua rau hluav taws ntawm cov khoom siv (xws li cov roj khib nyiab, cov kuab tshuaj lom organic) yuav tsum tau nyob hauv lub thawv tshwj xeeb tso rau hauv qhov chaw nyab xeeb, tsis txhob txhaum cai.
6, thaum muaj hluav taws, ua ntej txhua yam yuav tsum tshem tag nrho cov cua sov, tua cov roj thiab qhov rooj hluav taws xob, thiab tom qab ntawd duav nrog cov xuab zeb lossis asbestos qhov chaw tua hluav taws lossis nrog carbon tetrachloride thiab lwm lub tshuab tua hluav taws. Ntxiv rau dej cawv, tshuaj lom neeg, hluav taws kub, tsis tiv thaiv kom tua hluav taws.
7, yuav tsum xyuas cov cuab yeej hluav taws ib txwm: cov tshuaj tua hluav taws, xuab zeb, av tshauv thiab hnov zoo.
8, thaum cua sov, muab cub thiab lwm yam kev ua haujlwm ntsig txog kev siv hluav taws, yuav tsum muaj tus neeg lub luag haujlwm rau kev tswj hwm, tsis pub khiav tawm, khiav tawm ntawm cua sov tom qab taws tua.
9, txhuam tau yooj yim, tshwj xeeb tshaj yog cov hluav taws xob tawg yooj yim, yuav tsum muab cia rau hauv lub thawv kaw, tsis pub siv cov thawv qhib lub thawv ntim khoom kaw cia.
10. Cov khoom uas lub luag hauj lwm rau hluav taws yog:
Cov dej cawv, ethers, acetone, benzene, toluene, phenol, roj av, carbon disulfide, phosphorus, sodium peroxide, potassium, sodium thiab magnesium, calcium carbide.
11. Txhawm rau ua kom pom kev txhawm rau ua kom huv los yog nqus mus rau hauv Lub Tsev khaws puav pheej, yuav tsum siv hluav taws xob qhib hluav taws, muaj pes tsawg zaus yuav tsum tsis pub tshaj 100 milliliters, nyob ze cov khoom khaws cia yuav tsum tsis muaj nyob rau tib lub sijhawm, yuav tsum muaj kev tiv thaiv hluav taws.
