Txawm hais tias nws yog ib lub hoobkas kuaj los yog ib qho kev sim los sis ib qho kev sim tswj los ntawm tsoomfwv, nws yog qhov tsis txaus ntseeg tias yuav tsis muaj qhov tsis zoo ntawm qhov kev sim. Yog tias muaj tej yam tsis zoo tshwm sim, nws yuav cawm tau neeg li cas?
Ntawm no yog cov ntsiab lus ntawm yuav ua li cas nrog hluav taws hauv lub chaw kuaj ntshav thaum nws tuaj txog cov hluav taws hauv qhov chaw kuaj ntshav. Cov "raug mob" hauv txoj kev sim
Ua ntej tshaj plaws, tsis muaj dab tsi zoo li hluav taws, thawj lub sij hawm yuav tsum tau txiav tawm lub hwj chim, kom tsis txhob muaj kev tsim hluav taws kub, thaum muaj kev ruaj ntseg, thiab yuav tsum tau hu xov tooj rau 119 hluav taws hauv sij hawm.
1. Thaum lub tshuab sodium muaj hluav taws, cov xuab zeb tuaj yeem nchuav rau nws.
2. Thaum haus dej cawv thiab nws cov dej-soluble kua hluav taws kub, siv dej kom tua cov hluav taws.
3. Thaum cov xov hluav taws kub, nws tsis pub siv dej thiab roj carbon dioxide tua hluav taws. Lub hwj chim yuav tsum tau muab txiav tawm los yog cov pa roj carbon tetrachloride tua hluav taws.
4. Xyuam xim rau kev tiv thaiv ntawm lub tsev kawm ntawv thaum muaj hluav taws. Ib qho teeb meem loj ntawm hluav taws yuav tsum qhia tam sim ntawd.
5. Thaum lub khaub ncaws kub, tsis txhob khiav. Koj tuaj yeem qhwv koj lub cev nrog khaub ncaws los yog tsho tiv no los yog pw rau hauv av kom tua cov hluav taws.
6. Thaum cov tshuaj hnyav xws li roj av, hluav taws xob lossis toluene nyob rau hluav taws, siv cov ntaub asbestos lossis xuab zeb los tua. Tsis txhob siv dej, txwv tsis pub nws yuav ua rau thaj chaw kub nyhiab.
7. Thaum kua flammable kub kub, tshem tawm txhua yam khoom kub hnyiab hauv qhov chaw tua hluav taws thiab tua lub tshuab nqus cua kom tiv thaiv kom txhob muaj kev loj hlob ntxiv. Yog tias qhov chaw tua hluav taws me me, npog nws cov ntaub qhwv, cov ntaub so ntub, ntawv hlau lossis xuab zeb, thiab thaiv cov cua kom tua tau nws.
Txawm li cas los xij, nws yuav tsum maj mam them kom tsis txhob khob los sis khob cig ntim cov iav uas muaj cov kuab tshuaj, ua kom hnyav ntxiv ntws tawm thiab ntes hluav taws.
BOKA yog ib lub lag luam lag luam tshwj xeeb hauv kev npaj tsim dav dav thiab tsim kho ntawm kev sim. Cov khoom muaj xws li: sim raug tshem tawm, haj fume, chaw nres tsheb central, sab nraum rooj, roj fwj txee, ntuj nruab nrab, qhov cua tshuab, pneumatic system. Laboratory rooj tog thiab kuaj tshuab engineering xws li ntxuav tshuab.
