Dab tsi ntawm cov pa roj tuaj yeem kuaj tau los ntawm lub tshuab ntsuas roj?
Daim ntawv thov ntau ntawm cov khoom siv roj av tau dhau los ua qhov dav. Nws yog dav siv hauv kev lag luam petrochemical, kev lag luam kho dej, kev lag luam tshuaj, thiab kev lag luam zaub mov.
Hauv ntau lub lag luam kws tshuaj, vim muaj ntau yam khoom siv raw thiab cov khoom nruab nrab yog flammable, explosive los yog toxic chemicals, muaj ib tug leakage ntawm cov tshuaj lom, teeb meem los yog flammable gases nyob rau hauv cov tshuaj thiab cov txheej txheem tshuaj. Xaiv lub tswb hluav taws xob tsim hluav taws xob lossis lub ntsuas hluav taws xob rau kev tshawb nrhiav, uas tuaj yeem tshawb xyuas qee cov pa roj carbon monoxide zoo, ua kom muaj kev soj ntsuam zoo, thiab ua kom muaj kev nyab xeeb.
Gas detector yog ib qho cuab yeej cuab tam rau kev kuaj los yog ceeb toom roj to concentration, feem ntau muab faib ua handheld / tsau roj detectors. Nws siv cov pa roj sensors los xyuas cov hom roj uas muaj nyob hauv ib puag ncig, feem ntau yog siv los kuaj cov pa roj carbon monoxide, cov roj hluav taws xob sib txuas, lossis cov roj pa oxygen.
Combustible gas yog ib qho roj uas peb feem ntau ntsib hauv kev siv cov khoom siv roj ntsha. Lub tswv yim ntawm cov roj combustible yog hais txog cov roj uas tuaj yeem sib xyaw nrog huab cua (lossis oxygen) nyob rau hauv ib qho kev concentration ntau los tsim cov roj premixed. Thaum ntsib qhov hluav taws kub, nws yuav tawg thiab tso tawm ntau lub zog thaum lub sij hawm combustion txheej txheem.
Cov pa roj no feem ntau muaj nyob hauv thaj chaw ua haujlwm ntawm kev lag luam xws li petrochemicals thiab tshuaj tsim khoom. Cov pa roj carbon monoxide muaj xws li hydrogen (H2), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), acetylene (C3H4), acetylene (C4H6), thiab lwm yam.
Cov pa phem yog hais txog cov pa roj uas ua rau muaj kev hem thawj rau tib neeg lub cev thiab tuaj yeem ua rau lom. Lawv feem ntau muab faib ua cov pa roj carbon monoxide (xws li cov pa roj uas tuaj yeem ua rau lub qhov muag thiab ua pa mucosa) thiab asphyxiating gases (hais txog cov pa phem uas tuaj yeem ua rau hypoxia hauv lub cev, uas tuaj yeem muab faib ua cov pa ntshiab asphyxiating gases, ntshav asphyxiating gases, thiab cell asphyxiating gases). Cov pa roj no tuaj yeem ua rau tib neeg lub cev raug mob thiab tseem txaus ntshai heev. Cov pa roj carbon monoxide (CO), hydrogen sulfide (H2S), ammonia (NH3), chlorine (CL2), sulfur dioxide (SO2), nitrogen dioxide (NO2), nitric oxide (NO), carbon dioxide (CO2), thiab lwm yam.
