Txoj kev tsim khoom
Cov lus teb xwm txheej kub ntxhov rau qhov nchuav
Kev tiv thaiv cov neeg ua haujlwm, cov cuab yeej tiv thaiv thiab cov txheej txheem thaum muaj xwm txheej ceev: Nws raug nquahu kom cov neeg ua haujlwm thaum muaj xwm txheej ceev hnav lub tshuab ua pa, cov khaub ncaws tiv thaiv zoo li qub thiab cov hnab looj tes roj hmab.
Tsis txhob kov lossis hla qhov nchuav.
Tag nrho cov cuab yeej siv thaum lub sijhawm ua haujlwm yuav tsum tau earthed.
Tshem tawm qhov chaw ntawm qhov nchuav yog tias ua tau.
Tshem tawm txhua qhov chaw ntawm qhov hluav taws kub.
Txhais thaj chaw cordoned raws li thaj chaw cuam tshuam los ntawm cov kua ntws, vapor lossis plua plav dispersion thiab tshem tawm cov neeg tsis koom nrog mus rau thaj chaw nyab xeeb ntawm sab thiab sab saud.
Kev tiv thaiv ib puag ncig.
Khaws cov khoom nchuav kom tsis txhob muaj kev sib kis ntawm ib puag ncig.Tiv thaiv kom tsis txhob nchuav dej nkag mus rau hauv cov kav dej, dej saum npoo av thiab dej hauv av.
Cov txheej txheem ntawm kev ntim thiab tshem tawm cov tshuaj nchuav thiab cov khoom pov tseg siv: Cov nchuav me me: Sau cov kua uas nchuav rau hauv lub thawv ntim khoom yog tias ua tau.Ncua nrog xuab zeb, activated charcoal lossis lwm yam khoom siv inert thiab txav mus rau qhov chaw nyab xeeb.Kev tso dej rau hauv cov kav dej yog txwv tsis pub.Cov dej nchuav loj: Ua ib qho embankment los yog khawb ib lub qhov kom muaj nws.foob cov kav dej.Npog nrog ua npuas ncauj kom inhibit evaporation.Hloov mus rau lub tanker lossis cov khoom tshwj xeeb nrog lub twj tso kua mis tawg thiab rov ua dua lossis thauj mus rau qhov chaw kho mob pov tseg.
Kev tuav pov tseg thiab khaws cia
Kev ceev faj ua haujlwm:
Cov neeg ua haujlwm yuav tsum tau cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm nruj.
Kev tuav thiab pov tseg yuav tsum tau ua nyob rau hauv ib qho chaw uas muaj qhov cua hauv zos lossis dav dav.
Tsis txhob sib chwv qhov muag thiab tawv nqaij thiab nqus pa.
Khaws kom deb ntawm qhov hluav taws kub thiab cua sov thiab kev haus luam yeeb yog txwv tsis pub nyob hauv chaw ua haujlwm.
Siv cov tshuab ua pa tawm thiab cov khoom tawg.
Yog tias yuav tsum tau tanking, tswj tus nqi ntws thiab muaj cov khoom siv hauv av kom tsis txhob muaj qhov zoo li qub.
Tsis txhob sib cuag nrog cov khoom txwv tsis pub xws li oxidizing agents.
Ua tib zoo tuav kom tsis txhob muaj kev puas tsuaj rau lub ntim thiab ntim.
Cov thawv ntim khoom pov tseg tuaj yeem tso cov seem ntawm cov khoom tsis zoo.
Ntxuav tes tom qab siv thiab txwv tsis pub noj thiab haus hauv chaw ua haujlwm.
Ua kom muaj ntau yam thiab muaj nuj nqis ntawm cov khoom siv tua hluav taws thiab cov khoom siv hluav taws xob.
Kev ceev faj cia:
Khaws rau hauv ib lub khw muag khoom txias, ventilated.
Khaws cais los ntawm cov neeg ua haujlwm oxidizing thiab cov tshuaj noj tau thiab tsis txhob sib tov.
Khaws cov ntim ntim kaw.
Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
Cov cuab yeej tiv thaiv xob laim yuav tsum tau muab tso rau hauv chav cia khoom.
Cov pa hluav taws xob yuav tsum tau nruab nrog cov khoom siv hauv av los ua hluav taws xob zoo li qub.
Siv cov teeb pom kev tawg-pov thawj thiab qhov cua qhov chaw.
Kev siv cov khoom siv hluav taws xob thiab cov cuab yeej raug txwv tsis pub siv.
Qhov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv thaum muaj xwm txheej ceev thiab cov khoom siv vaj tse tsim nyog.
