Cov khoom siv hluav taws xob hluav taws xob txawb hluav taws xob tau siv ntau yam hluav taws kub thiab hluav taws kub ceev xwm txheej. Lawv lub luag haujlwm tseem ceeb yog kom tshem tawm cov pa taws sai sai, txhim kho kev pom thiab huab cua zoo, thiab tsim kom muaj chaw nyab xeeb rau kev tshawb nrhiav thiab cawm thiab tua hluav taws. Lawv txoj kev txav mus los thiab kev hloov pauv tau tso cai rau lawv ua lub luag haujlwm tseem ceeb hauv qhov chaw uas cov pa luam yeeb tshem tawm tsis yooj yim los npog lossis tsis tuaj yeem qhib tau sai.
Hauv kev tsim kho hauv nroog, lawv tau siv dav rau kev tshem tawm cov pa luam yeeb hauv cov tsev siab -nce, ntau-cov tsev nyob hauv tsev, cov chaw lag luam, thiab tsev so. Thaum cov stairwells, txoj kev hauv tsev, lossis txoj kev taug kev raug txwv los ntawm cov pa taws thiab hluav taws, lub tsev tshem tawm cov pa luam yeeb tuaj yeem txav tau nrog cov neeg tua hluav taws los tsim cov pa cua ib ntus ntawm cov hluav taws kub hauv pem teb thiab cov chaw uas nyob ib sab, txo lub sijhawm lub qhov rais rau kev khiav tawm thiab cawm cov neeg raug kaw. Cov chaw hauv av yog lwm qhov tseem ceeb ntawm daim ntawv thov, suav nrog cov chaw nres tsheb hauv av, subway platforms, tunnels, thiab warehouse basements. Cov chaw no muaj cov txheej txheem kaw thiab txwv txoj kev tshem tawm cov pa luam yeeb, ua rau nws nyuaj rau cov cuab yeej ruaj khov kom ncav cuag qhov ze ntawm qhov hluav taws kub. Cov pa luam yeeb ntawm lub xov tooj txawb tuaj yeem hloov pauv tau yooj yim ntawm kev nkag los yog nyob ze ntawm lub qhov cua kom muaj txiaj ntsig zoo cuam tshuam cov pa taws kub siab - kub.
Hauv kev lag luam thiab cov chaw tshwj xeeb, nws tsim nyog rau qhov loj lossis ib nrab -qhib qhov chaw xws li chaw ua haujlwm hauv chaw ua haujlwm, thaj chaw roj tank hauv tsev ntxiv, thiab cov chaw xa khoom thauj khoom. These environments often feature dense distribution of flammable materials and high heat release rates. Cov pa luam yeeb extractors, ua ke nrog kev ntsuas cua txias, tuaj yeem ua rau qeeb kis hluav taws thiab tsim cov xwm txheej rau kev tawm tsam sab hauv. Tsis tas li ntawd, nyob ze lossis ib nrab- qhov chaw kaw xws li lub nkoj cabins, dav hlau hangars, VIP chaw lossis cov khoom siv hauv tsev hauv cov chaw ntau pob kuj tuaj yeem suav nrog hauv nws daim ntawv thov, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ua haujlwm tsis ua haujlwm lossis kev tsim kho qeeb, qhov uas nws tuaj yeem ua haujlwm ntxiv rau kev tshem tawm cov pa taws thaum muaj xwm txheej ceev.
Los ntawm ib qho kev hloov pauv ntawm ib puag ncig, hluav taws xob hluav taws xob- tawm tsam cov pa luam yeeb tuaj yeem ua haujlwm rau lub sijhawm luv luv hauv ib puag ncig nrog qee qhov ntau ntawm cov plua plav, dej vapor, thiab cov pa phem me me. Txawm li cas los xij, qhov kub thiab txias heev, muaj zog corrosion, lossis oxygen- qhov chaw tsis txaus yuav txwv lawv lub sijhawm ua haujlwm tsis tu ncua thiab qhov chaw xa tawm. Roj- cov qauv siv hluav taws xob tsim nyog rau qhov chaw sab nraum zoov lossis thaj chaw deb yam tsis muaj hluav taws xob sab nraud thiab yuav tsum tau ua haujlwm ntev -, thaum cov qauv hluav taws xob tsim nyog rau cov chaw sab hauv tsev nrog cov suab nrov nruj thiab cov pa tawm.
Siv cov pa luam yeeb tshem tawm cov kiv cua hauv qhov chaw nres tsheb hauv av hluav taws tuaj yeem txo qhov pom kev rov kho lub sijhawm nyob rau hauv lub voj voog ua haujlwm tau zoo txog li 30% ntawm lub sijhawm qub thiab txhim kho qhov ua tiav ntawm kev tshawb nrhiav thiab cawm. Yog li ntawd, daim ntawv thov hluav taws xob hluav taws xob- tawm tsam cov kiv cua tshem tawm cov pa taws txuas ntxiv tshaj li cov vaj tse thiab cov chaw hauv av rau cov chaw tsim khoom thiab cov chaw tshwj xeeb. Lub ntsiab lus tseem ceeb yog kom xa lawv raws li cov qauv ntawm qhov chaw thiab cov yam ntxwv ntawm cov pa luam yeeb kom ua kom lawv cov pa luam yeeb ntau tshaj plaws thiab kev tiv thaiv kev nyab xeeb.
