Yuav ua li cas xaiv qhov kev tshawb pom zoo ntawm cov tshuaj lom thiab phom sij ntawm cov pa phem
1) Paub meej tias hom roj yuav tsum tau kuaj thiab cov concentration ntau:
Txhua lub tuam tsev tsim khoom ntsib ntau hom roj av. Thaum xaiv lub ntsuas roj nws yog ib qho tseem ceeb uas yuav tau xav txog txhua yam tshwm sim. Yog tias methane thiab lwm yam tshuaj lom alkanes tsawg dua, qhov kev xaiv ntawm LEL detector yog qhov tsim nyog tshaj plaws. Qhov no tsis yog vim LEL ntes tau yooj yim thiab siv dav, tab sis kuj vim tias nws yooj yim los tswj thiab ntsuas. Yog tias muaj cov pa phem xws li cov pa roj carbon monoxide, hydrogen sulphide, thiab lwm yam, nws yog ib qho tseem ceeb uas yuav tsum tau ua qhov tseem ceeb rau cov khoom siv hluav taws xob tshwj xeeb txhawm rau ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Yog tias muaj cov pa roj carbon monoxide ntau dua thiab muaj kev phom sij, suav nrog lawv qhov qis qis uas yuav ua rau cov neeg ua haujlwm lom lom, xws li cov pa roj carbon monoxide, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, lipids, thiab lwm yam. tshooj dhau los yuav tsum tau xaiv es tsis txhob siv lub ntsuas LEL los tiv thaiv lawv, uas yuav ua rau raug mob lossis tuag.
Yog hais tias cov roj hom npog cov pawg saum toj no, yuav ua li cas xaiv cov khoom siv tshuaj lom thiab phom sij
Rau txhua yam kev tsim khoom sib txawv thiab kev tshawb nrhiav yuav tsum tau ua, xaiv cov khoom siv hluav taws xob zoo yog txhua tus neeg koom nrog kev nyab xeeb thiab kev tshawb nrhiav haujlwm yuav tsum tau ua tib zoo saib xyuas. Ntawm no peb yuav ua qhov kev nthuav qhia ntawm qee qhov tshwj xeeb rau koj siv.
Yog tias koj siv cov cuab yeej no los ua lub tswb nrov hauv cov xwm txheej qhib, xws li lub rooj cob qhia qhib, koj tuaj yeem siv lub tshuab hluav taws xob diffusion gas detector vim nws tuaj yeem ua haujlwm tsis tu ncua, lub sijhawm tiag tiag thiab ua kom pom tseeb ntawm cov pa phem thiab cov pa phem ntawm qhov chaw. Qee yam ntawm cov cuab yeej tshiab no kuj tseem haum nrog kev co lub tswb txuas - kom tsis txhob hnov qab tsis hnov tsw suab nrov hauv ib puag ncig tsis muaj suab nrov - thiab lub khoos phis tawj lub computer kom sau cov ncov siab, STEL (15-feeb luv luv Theem Tawm) thiab TWA (8- teev Statistical Weighted Average). - Muab cov lus qhia tshwj xeeb rau cov neeg ua haujlwm noj qab haus huv thiab kev nyab xeeb.
