Yuav ua li cas xaiv Lim Daim Qauv Lim rau ib nrab ntawm lub ntsej muag ua pa raws li cov chaw ua haujlwm
I. Cov Txheej Txheem Tseem Ceeb rau XaivLim cartridges
Txheeb xyuas cov hom phom sij
Tshuaj Tshuaj Muaj Zog: Gases (piv txwv li, chlorine, ammonia), vapaces (piv txwv li cov kuab tshuaj organic, mercury), particulous), thiab cov pa luam yeeb).
Cov siab ntau: Cov ntxaij lim tsuas yog ua tau zoo thaum muaj kuab paug siab nyob hauv qab Idlh (qis qis rau lub neej thiab qib noj qab haus huv).
Cov pa oxygen: Cov ntxaij lim dej tsis tuaj yeem siv hauv cov pa oxygen tsis txaus (<19.5% O₂; switch to supplied-air respirators).
Ii. Lim Cartridge Hom thiab Cov Ntawv Sau Npe
| Lim Hom | Xim code | Kev Tiv Thaiv Lub Hom Phiaj | Cov chaw ua haujlwm raug ua haujlwm |
|---|---|---|---|
| Ntaus ib (organic vapor) | Xim kas fes | Benzene, roj av, acetone, pleev xim rau fumes | Txau cov duab, petrochemical cov chaw |
| Ntaus B (Acid Gases) | Xim txho | Chlorine, Hydrogen Sulfide, Sulphur Dioxide | Cov Kev Kho Kom Qhuav, Electroplating |
| Hom E (Alkaline Gases) | Xim daj | Ammonia, methylramine | Chiv Ntau Lawm, Tub Yees Dej |
| Hom K (ammonia & derivatives) | Xim ntsuab | Ammonia, methylramine | Ua liaj / teb, tsiaj txhu ua liaj ua teb |
| Hom co (carbon monoxide) | Xim liab | Carbon monoxide | Kev tua hluav taws, cov pa tsheb kho |
| Partetulation lim lim (P100 / N95) | Dawb / Txiv kab ntxwv | Hmoov av, haus luam yeeb, pathogens | Woodworking, Kev Kho Mob |
| Ntau nkas roj + particulate (abek + p3) | Txaij | Ua ke tiv thaiv (organic + acid + alkaline + hais) | Chaw ua hauj lwm chaw ua hauj lwm, sib xyaw-cov chaw muaj kev phom sij |
III. Scenario raws li kev xaiv cov txheej txheem
Cov xwm txheej 1: Txau xim (organic vapors + particulates)
Kev Ntsuam Xyuas Kev Ruaj Ntseg: Benzene cov tebchaw (VOCS) + xim pleev xim rau cov lus.
Lus teb:
Ntaus ib (xim av) cartridge + P100 particulate lim lim(piv txwv li, 3m 6001 cartridge + 5 l11 lim).
Rau formaldehyde tiv thaiv, sivNtaus A + formaldehyde-specyst catalyst Cartridge(piv txwv li, msa 817661).
Cov xwm txheej 2: chlorine xau hauv cov nroj tsuag tshuaj (kua roj acid)
Kev Ntsuam Xyuas Kev Ruaj Ntseg: Chlorine (cl 0.) siab<30ppm (NIOSH limit).
Lus teb:
Hom B (Grey) Cartridge(piv txwv li, Honeywell 7580P1002B), Tshawb xyuas Clau Max concentration ntsuas ntsuas.
Ntxiv cov particulations lim yog sulphuricic acid yog tam sim no.
Cov xwm txheej 3: ammonia raug nyob hauv kev ua liaj ua teb
Kev Ntsuam Xyuas Kev Ruaj Ntseg: Ammonia (nh₃) concentration<300ppm (EN 14387 standard).
Lus teb:
Hom K (Ntsuab) Cartridge(piv txwv li, drager x-plore 8100 k; ua ntej ammonia-lim tshwj xeeb tshaj li General hom e).
Scenario 4: Kev phom sij sib xyaw hauv Chaw Muag Khoom Siv
Kev Ntsuam Xyuas Kev Ruaj Ntseg: Muaj peev xwm nthuav tawm rau cov kua qaub / alkali gases, cov kuab tshuaj, thiab particulates.
Lus teb:
AFFEK + P3 muaj roj cartridge(piv txwv li, Scott Pro2000 ABEK1); ua kev ntsuas kev phom sij.
IV. Kev txiav txim siab tseem ceeb
Kev Pabcuam Lub Neej:
Ntaus ib (organic vapor): Hloov tsis pub dhau 30 hnub tom qab qhib, txawm tias tsis siv cov roj carbon ua haujlwm tsis tau vim yog noo noo).
Ntaus B (Acid Gases): Halve pab txoj kev ua neej nyob rau hauv cov av noo ib puag ncig.
Cov tshev nyiaj ntau:
Xyuas kom cov cartridge-rau-npog interface sib ncab (piv txwv li, 40mm xov los yog bayonet mount; MSA cartridges yog tsis sib xws nrog 3m 6000 series).
Qhov kawg-ntawm-kev pab cuam:
Cov ntxhiab xav tau: Tawm tam sim ntawd yog tias roj tsw tau raug kuaj pom (siv tsuas yog siv roj nrog cov khoom ceeb toom).
Smart Timers: Siv rfid-enledled cartridges (piv txwv li, 3m 6000 series) los taug cov xuaj moos siv tau.
