Nyob rau hauv cov ntaub ntawv no, yuav tsum tau siv ib tug ua npuas ncauj los yog qhuav hmoov extinguisher, raws li lawv yog tsim los smother qhov hluav taws kub thiab tsim ib tug barrier ntawm cov roj thiab cov pa.
3. Ua Cov Roj thiab Roj Hluav Taws Xob:
Thaum cov roj los yog roj ua rau hluav taws kub, nws tuaj yeem ua rau muaj kev phom sij heev thiab nyuaj rau kev tua. Cov dej siv rau roj lossis roj hluav taws tuaj yeem ua rau muaj hluav taws kub hnyiab, ua rau cov roj hlawv thiab ua kom hluav taws kub. Rau cov roj ua noj thiab roj hluav taws kub, nws raug nquahu kom siv daim pam hluav taws lossis Chav K tua hluav taws tshwj xeeb tsim rau hluav taws kub hauv chav ua noj.
4. Combustible Metals:
Dej yuav tsum tsis txhob siv rau ntawm cov hluav taws kub uas muaj hlau xws li magnesium, titanium, lithium, lossis potassium. Cov hlau no hnov mob hnyav nrog dej, ua rau muaj kev cuam tshuam tawg. Rau cov hluav taws kub uas muaj cov hlau combustible, cov hmoov qhuav tshwj xeeb tua hluav taws yuav tsum tau ua kom muaj hluav taws kub thiab tiv thaiv kom tsis txhob kis tau.
5. Cov neeg tsis tau kawm:
Txawm hais tias cov dej tua hluav taws tuaj yeem ua haujlwm tau zoo ntawm cov neeg tau txais kev cob qhia zoo, nws tseem ceeb heev uas yuav tsum tau ceev faj. Cov neeg tsis paub dhau los lossis tsis tau txais kev cob qhia yuav ua yuam kev siv dej tsis tsim nyog, ua rau muaj kev phom sij ntxiv thiab txaus ntshai. Tshwj tsis yog tias tau txais kev cob qhia kom raug, nws raug nquahu rau cov neeg tsis paub txog kev khiav tawm ntawm thaj chaw thiab tso cai rau cov kws tshaj lij los daws qhov xwm txheej.
Lwm txoj hauv kev tua hluav taws:
Hauv cov xwm txheej uas cov dej tua hluav taws tsis tsim nyog, nws yog ib qho tseem ceeb uas yuav tsum siv lwm txoj kev tua hluav taws:
1. Cov pa roj carbon dioxide (CO2) Extinguishers:
CO2 extinguishers yog tshwj xeeb tshaj yog zoo rau hluav taws xob hluav taws xob thiab hluav taws kub ua kua.
