Cov haujlwm hauv qab no yog txwv rau cov neeg uas tau nyob hauv chav kuaj txhua xyoo puag ncig.Xiao Bian tau txheeb xyuas lawv hnub no thiab xa lawv sai sai rau txhua tus kawm!
1. Lub tub yees foob pob
Thaum lub sij hawm rho tawm lossis lim ntshav, cov organic reagents yog siv thiab muab tso rau hauv lub tub yees qhib.Raws li cov organic gas mus txog qhov tseem ceeb concentration, nws yog ignited los ntawm hluav taws xob spark thaum lub tub yees compressor pib.
Lub Kaum Hli 6, 1986, lub tub yees hauv lub koom haum tshawb fawb ntawm Suav Academy ntawm Kev Tshawb Fawb tau tawg;
Thaum Lub Kaum Ob Hlis 15, 1987, lub tub yees hauv chav kuaj ntawm Ningxia Academy ntawm Kev Tshawb Fawb Txog Kev Ua Liaj Teb tau tawg;
Thaum Lub Xya Hli 20, 1988, "Shasong" tub yees hauv tsev ntawm tus kws qhia ntawv hauv Nanjing Normal University tawg.
Tsuas yog ob peb xyoos xwb, muaj ntau tshaj 10 tshaj tawm cov tub yees tawg.Qhov ua rau muaj kev sib tsoo tsis yog qhov zoo ntawm lub tub yees nws tus kheej, tab sis cov tshuaj xws li roj av ether, acetone, benzene thiab butane gas tau muab tso rau hauv lub tub yees.Peb paub tias qhov kub ntawm lub tub yees yog qis.Yog hais tias cov tshuaj flammable thiab explosive chemicals uas tsis muaj boiling point thiab flash point muab tso rau hauv lub tub yees, lawv yuav volatilize flammable gas nyob rau hauv qis kub tej yam kev mob.Txawm hais tias lub hau lub raj mis yog nruj nreem, qhov kub tsis tshua muaj feem ntau ua rau lub plhaub lub raj mis kom qis, cov roj valve kom xoob lossis txawm tias lub plhaub lub raj mis tawg.Cov roj uas tsis muaj hluav taws xob sib xyaw ua ke nrog huab cua los ua ib qho kev sib xyaw tawg thiab ua rau lub tub yees.Cov hluav taws xob hluav taws xob tsim tawm thaum lub ntsuas kub tswj (lossis lwm yam tswj cov keyboards) qhib lossis kaw yog qhov yooj yim heev rau tawg.Yog li ntawd, cov neeg siv tub yees yuav tsum tsis txhob khaws cov tshuaj hauv lub tub yees.
2. Ncuav dej cawv nrog qhib hluav taws
Qhib qhov kub nyhiab ntawm lub teeb cawv nrog cov pliers, thiab ncuav cawv rau hauv lub teeb cawv nrog ib txhais tes, uas yuav ua rau tag nrho lub raj mis cawv hlawv thiab tawg.
3. Kua nitrogen foob pob
Siv iav thiab buckle npog centrifuge raj los ntim cov qauv thiab muab tso rau hauv cov kua nitrogen tso tsheb hlau luam.Thaum lawv raug muab tshem tawm, cov khoom ntawm cov yeeb nkab phab ntsa tau hloov pauv, thiab lawv tsis tuaj yeem tiv taus cov pa nthuav dav, lossis lub siab tsis sib xws thaum lawv tau sov so sai, ua rau tawg.
Yog li ntawd, cov neeg uas hnav tsom iav muaj qhov zoo dua - "Lub iav nyob ntev!"
Cov neeg ua haujlwm uas nquag nqa cov kua nitrogen yuav tsum hnav cov tsom iav yas.
Hazard Txheej txheem cej luam
Kev phom sij rau kev noj qab haus huv: Cov khoom no yog incombustible thiab asphyxiant, thiab daim tawv nqaij sib cuag nrog kua nitrogen yuav ua rau frostbite.Yog hais tias cov nitrogen uas ua los ntawm vaporization yog ntau dhau nyob rau hauv ib txwm kub, ib feem ntawm cov pa oxygen nyob rau hauv cov huab cua yuav poob, ua rau anoxic asphyxia.
Kev pab thawj zaug
Tiv tauj daim tawv nqaij: Yog tias muaj frostbite, nrhiav kev kho mob.
Inhalation: sai sai tawm ntawm qhov chaw mus rau huab cua ntshiab thiab ua pa kom du.Yog ua pa nyuaj, muab cov pa oxygen.Yog tias ua tsis taus pa, ua pa ua pa tam sim ntawd thiab nrhiav kev kho mob.
Kev ntsuas hluav taws kub
Hazard: Thaum tshav kub kub, lub siab sab hauv ntawm lub thawv yuav nce, uas yuav ua rau tawg thiab tawg.
Extinguishing method: Cov khoom no yog incombustible, thiab cov ntim rau hauv qhov chaw tua hluav taws yuav tsum cia txias nrog pos huab.Lub vaporization ntawm cov kua nitrogen tuaj yeem nrawm nrawm los ntawm kev txau dej hauv daim ntawv ntawm huab cua, thiab cov phom dej yuav tsum tsis txhob tua kua nitrogen.
Kev kho mob thaum muaj xwm ceev
Kev kho mob thaum muaj xwm txheej ceev: tshem tawm cov neeg ua haujlwm sai sai hauv qhov chaw xau cov kab mob mus rau qhov chaw cua, cais lawv, thiab txwv kev nkag mus.Cov neeg ua haujlwm kub ntxhov yuav tsum hnav lub tshuab ua pa zoo rau tus kheej thiab cov khaub ncaws txias.Tsis txhob kov cov xau ncaj qha.Txiav tawm qhov dej ntws tawm kom ntau li ntau tau.Tiv thaiv cov pa roj los ntawm kev sib sau ua ke hauv qhov chaw qis thiab tawg thaum ntsib qhov chaw tshav kub.Siv tus kiv cua tso pa xa cov pa tawm mus rau qhov chaw qhib.Cov thawv ntim dej yuav tsum tau kho kom zoo, kho thiab tshuaj xyuas ua ntej siv.
Kev tuav thiab ruaj khov
Kev ceev faj rau kev ua haujlwm: kaw kev ua haujlwm, muab qhov zoo ntawm qhov cua.Cov neeg ua haujlwm yuav tsum raug cob qhia thiab ua raws li cov txheej txheem ua haujlwm.Nws raug nquahu kom cov neeg ua haujlwm hnav cov hnab looj tes tiv thaiv khaub thuas.Tiv thaiv kom tsis txhob muaj roj paug rau hauv huab cua ntawm qhov chaw ua haujlwm.Lub tog raj kheej thiab cov khoom siv yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj kev puas tsuaj.Muab cov khoom siv thaum muaj xwm ceev rau cov dej xau.
Kev ceev faj rau kev khaws cia: Khaws rau hauv qhov chaw txias thiab qhov cua zoo, thiab qhov kub yuav tsum tsis pub tshaj 50 ℃.
Kev tiv thaiv tus kheej
Kev tiv thaiv kab mob ua pa: feem ntau yuav tsum tsis muaj kev tiv thaiv tshwj xeeb.Txawm li cas los xij, thaum cov pa oxygen concentration hauv qhov chaw ua haujlwm qis dua 19%, lub tshuab ua pa, cov pa oxygen thiab lub qhov ncauj qhov ntswg ntev yuav tsum tau hnav.
Kev tiv thaiv qhov muag: hnav daim npog qhov ncauj kev nyab xeeb.
Kev tiv thaiv tes: hnav cov hnab looj tes tiv thaiv khaub thuas.
Lwm yam kev tiv thaiv: Tsis txhob nqus cov pa siab kom tiv thaiv frostbite.
