Kev pov tseg thiab kev cia khoom thiab kev thauj mus los ua haujlwm:
Kev ceev faj ua haujlwm:Kev ua haujlwm kaw, txhawb kom muaj cua nkag. Cov neeg ua haujlwm yuav tsum tau kawm tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug pom zoo kom cov neeg ua haujlwm hnav lub ntsej muag lim plua plav uas muaj peev xwm nqus tau tus kheej, cov tsom iav tiv thaiv kev nyab xeeb tshuaj, cov khaub ncaws ua haujlwm uas nkag mus rau hauv lub tshuab ua pa, thiab cov hnab looj tes roj hmab. Tsis txhob ua kom muaj plua plav. Tsis txhob kov cov kua qaub. Thaum tuav, yuav tsum tau thauj khoom me me thiab tshem tawm kom tiv thaiv kev puas tsuaj rau cov ntim khoom thiab cov thawv. Nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev. Lub thawv khoob yuav muaj cov khoom seem tsis zoo.
Kev ceev faj txog kev khaws cia:Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag tau zoo. Khaws cia kom deb ntawm hluav taws thiab cua sov. Khaws lub thawv kom kaw. Yuav tsum khaws cia cais ntawm cov kua qaub, tsis txhob sib xyaw ua ke. Qhov chaw khaws cia yuav tsum muaj cov khoom siv tsim nyog los tswj cov dej xau.
Txoj kev ntim khoom:Lub thawv ntoo ib txwm sab nraum lub raj mis ampoule; Lub raj mis iav uas muaj xov, lub hau hlau nias lub raj mis iav, lub raj mis yas lossis cov thoob hlau (cov kaus poom) sab nraum lub thawv ntoo ib txwm. Tsis muaj dej noo thiab kaw cia. Khoom ntim: 25KG/HNAB.
Kev ceev faj txog kev thauj mus los:Cov tsheb thauj khoom yuav tsum tau nruab nrog ntau yam thiab ntau npaum li cas ntawm cov khoom siv tua hluav taws thiab cov khoom siv kho mob thaum muaj xwm txheej ceev. Thaum lub caij ntuj sov, nws yog qhov zoo tshaj plaws los xa khoom thaum sawv ntxov thiab yav tsaus ntuj. Lub tsheb thauj khoom (tank) siv rau hauv kev thauj mus los yuav tsum muaj cov saw hlau av, thiab ib qho kev faib qhov tuaj yeem npaj rau hauv lub qhov kom txo cov hluav taws xob static tsim los ntawm kev poob siab. Nws raug txwv tsis pub sib xyaw nrog oxidizer. Thaum lub sijhawm thauj mus los, nws yuav tsum tau tiv thaiv los ntawm tshav ntuj, nag thiab kub siab. Nyob deb ntawm nplaim taws, qhov chaw kub thiab thaj chaw kub siab thaum lub sijhawm nres. Cov kav dej tso pa tawm ntawm cov tsheb thauj khoom yuav tsum tau nruab nrog cov khoom siv hluav taws kub. Kev thauj khoom thiab tshem tawm nrog cov khoom siv kho tshuab thiab cov cuab yeej uas yooj yim tsim hluav taws xob raug txwv. Kev thauj mus los ntawm txoj kev yuav tsum ua raws li txoj kev tau teev tseg, tsis txhob nyob hauv thaj chaw nyob thiab thaj chaw muaj neeg coob coob. Nws raug txwv tsis pub muab lawv tso rau hauv kev thauj mus los ntawm tsheb ciav hlau. Cov nkoj ntoo thiab cov nkoj cement raug txwv tsis pub thauj khoom ntau.
