Hauv lub ntiaj teb ntawm kev lag luam thiab kev lag luam ib puag ncig, muaj qee qhov chaw uas muaj cov khoom phom sij xws li cov pa hluav taws xob, vapors, thiab cov kua dej tam sim no. Cov chaw muaj kev phom sij no tuaj yeem pom nyob rau hauv qhov chaw xws li refineries, tshuaj nroj tsuag, khw muag xim, petrochemical chaw, thiab lwm yam.
Txhawm rau txo qhov kev pheej hmoo ntawm kev tawg lossis hluav taws uas tshwm sim los ntawm cov khoom siv hluav taws xob, suav nrog cov khoom siv teeb pom kev zoo, cov khoom siv hluav taws xob tawg yuav tsum muaj nyob rau hauv cov chaw muaj kev phom sij no. Cov khoom tawg-pov thawj teeb pom kev zoo yog tsim los nrog cov ntaub thaiv tshwj xeeb uas muaj peev xwm muaj qhov tawg uas yuav tshwm sim, kom cov khoom siv phom sij tsis raug hluav taws xob los ntawm cov khoom siv hluav taws xob.
Tab sis dab tsi raws nraim yog cov hom kev phom sij uas yuav tsum tau tawg-pov thawj teeb pom kev zoo? Cia peb saib ntxiv:
Chav Kawm I, Division 1 Qhov chaw:Cov no yog cov chaw uas muaj cov pa hluav taws xob, vapors, thiab cov kua dej muaj nyob rau hauv kom muaj nuj nqis txaus rau ignite thiab tawg. Piv txwv ntawm cov chaw no muaj xws li cov chaw khaws roj av, refineries, thiab natural gas processing plant.
Chav Kawm I, Division 2 Qhov chaw:Cov no yog cov chaw uas muaj cov pa hluav taws kub, vapors, thiab cov kua dej tam sim no, tab sis tsuas yog muaj me me thiab nyob rau hauv ib txwm muaj. Txawm li cas los xij, nyob rau hauv cov xwm txheej txawv txav, xws li cov khoom siv tsis ua haujlwm lossis cov dej nchuav, cov chaw no tuaj yeem ua rau muaj kev phom sij. Piv txwv ntawm cov chaw no muaj xws li cov khw pleev xim thiab cov nroj tsuag tshuaj.
Chav Kawm II, Division 1 Qhov chaw:Cov no yog cov chaw uas muaj cov plua plav hluav taws xob, xws li thee, hmoov nplej, lossis sawdust, muaj ntau txaus rau ignite thiab tawg. Piv txwv ntawm cov chaw no muaj xws li grain elevators thiab thee tuav cov chaw.
Chav II, Division 2 Qhov chaw:Cov no yog cov chaw uas muaj cov plua plav combustible, tab sis tsuas yog nyob rau hauv me me thiab nyob rau hauv tej yam kev mob. Txawm li cas los xij, nyob rau hauv cov xwm txheej txawv txav, xws li cov khoom siv tsis ua haujlwm lossis cov dej nchuav, cov chaw no tuaj yeem ua rau muaj kev phom sij. Piv txwv ntawm cov chaw no suav nrog cov chaw tsim khoom uas tsim cov hmoov hlau lossis tshuaj.
Chav Kawm III Qhov Chaw:Cov no yog cov chaw uas yooj yim ignitable fibers lossis cov ntaub ntawv tam sim no, xws li paj rwb lint lossis ntoo shavings. Piv txwv ntawm cov chaw no suav nrog cov nroj tsuag textile lossis cov chaw ua haujlwm ntoo.
Hauv kev xaus, yog tias koj tab tom ua haujlwm hauv qhov chaw muaj kev phom sij uas muaj cov pa hluav taws xob, vapors, kua, lossis cov plua plav uas tuaj yeem tshwm sim, cov khoom siv hluav taws xob tawg yog qhov yuav tsum muaj. Cov teeb pom kev zoo tshwj xeeb no yog tsim los tiv thaiv qhov hluav taws kub ntawm cov khoom siv phom sij, muab qhov chaw nyab xeeb rau cov neeg ua haujlwm thiab tiv thaiv kev puas tsuaj rau cov khoom.
