Nws tuaj yeem muab faib rau cov kab mob uas tsis sib raug zoo thiab tsis raug. Thaum cov pa roj paug, 15% lossis ntau tshaj ntawm cov huab cua yuav ua rau cov pa tsis muaj zog rau lub cev thiab lub paj hlwb raug mob, loj npaum li cas, nws yuav ua rau cov kab mob tuag tes tuag taw, coma, thiab tuag taus. Cov roj gas kuj yog ib qho tseem feem ntau flammable thiab explosives chemicals, nws cov pa hauv cov cua mus txog 3.6% ~ 6.5% thiab ntsib hluav taws yuav tawg. Yuav kom tsis txhob tshwm sim ntawm cov xwm txheej, nws yog qhov tsim nyog rau peb siv cov kev ntsuas ntawm concentration ntawm liquefied gas nyob rau hauv cov pa los tiv thaiv ua ntej.
LPG roj tswb yog ib qho cuab yeej tiv thaiv kom tsis txhob muaj teeb meem, ua kom muaj zog, tawg thiab tawg taus hauv cov txheej txheem ntawm cov khoom siv thiab kev siv.Qhov kev siv, lub tswb teem caij qis tshaj ntawm kev tawg (xws li 20% LEL) . Thaum muaj cov pa roj carbon dioxide tuaj txog qis qis qeeb (lub tswb nrov), lub tswb ceeb toom tam sim ntawd tswb, txiav tawm lub hwj chim, thiab qhib qhov cua tshuab tib lub sij hawm kom cov neeg ua haujlwm tuaj yeem ua haujlwm nrog thaum muaj xwm ceev hauv ib lub sij hawm twg.Thaum ib rab phom loj heev los tiv thaiv kom tsis muaj pa taws, lub tswb ntsuas tsis zoo rau tib neeg saib xyuas. Qhov no yuav muab piv rau lub tua hluav taws rau kev tiv thaiv kev ruaj ntseg. Qhov ntsuas hluav taws xob yog ib qho tseeb ntawm cov roj liquefied , nws yog mob siab, teb cov lus teb sai sai.Qhov kev tawm tsam roj yog dav siv nyob rau hauv chaw muaj xws li cov chaw muaj roj liquefied chaw nres tsheb, chaw filling tsheb, chav boiler, thiab lwm yam. Nws tuaj yeem tiv thaiv kev raug mob lom, tawg, thiab hluav taws, lav kev ruaj ntseg ntawm lub neej thiab vaj tse.
