Nws muaj peev xwm rau ib lub chaw tsim khoom siv dav dav, xws li lub Hoobkas khaub ncaws, los ua lub chaw tsim khoom siv npog ntsej muag, tab sis muaj ntau yam teeb meem uas yuav tsum kov yeej. Nws kuj tsis yog ib qho txheej txheem ib hmos, vim tias cov khoom yuav tsum tau txais kev pom zoo los ntawm ntau lub koom haum thiab cov koom haum. Cov teeb meem suav nrog:
Kev tshawb nrhiav cov koom haum qauv kev xeem thiab daim ntawv pov thawj.Ib lub tuam txhab yuav tsum paub txog lub vas sab ntawm cov koom haum kuaj thiab cov chaw muab ntawv pov thawj thiab leej twg tuaj yeem muab cov kev pabcuam rau lawv. Cov koom haum tsoomfwv suav nrog FDA, NIOSH, thiab OSHA teeb tsa cov kev cai tiv thaiv rau cov neeg siv khoom kawg xws li lub ntsej muag, thiab tom qab ntawd cov koom haum xws li ISO thiab NFPA teeb tsa cov kev cai ua haujlwm nyob ib puag ncig cov kev cai tiv thaiv no. Tom qab ntawd cov koom haum txoj kev kuaj xws li ASTM, UL, lossis AATCC tsim cov txheej txheem txheem los xyuas kom meej tias cov khoom muaj kev nyab xeeb. Thaum lub tuam txhab xav kom daim ntawv pov thawj cov khoom muaj kev nyab xeeb, nws xa nws cov khoom mus rau lub koom haum pov thawj xws li CE lossis UL, uas tom qab ntawd kuaj cov khoom nws tus kheej lossis siv lub chaw kuaj thib peb uas tau lees paub. Cov kws ua haujlwm soj ntsuam cov txiaj ntsig ntawm kev xeem raws li cov lus qhia kev ua tau zoo, thiab yog tias nws dhau, lub koom haum muab nws lub cim rau ntawm cov khoom los qhia tias nws muaj kev nyab xeeb. Tag nrho cov koom haum no muaj kev sib raug zoo; cov neeg ua haujlwm ntawm cov koom haum pov thawj thiab cov chaw tsim khoom zaum ntawm cov thawj coj ntawm cov koom haum qauv nrog rau cov neeg siv khoom kawg ntawm cov khoom. Ib lub chaw tsim khoom tshiab yuav tsum muaj peev xwm taug kev hauv lub vas sab ntawm cov koom haum uas tswj hwm nws cov khoom tshwj xeeb kom ntseeg tau tias lub ntsej muag lossis lub tshuab ua pa uas nws tsim tau ntawv pov thawj zoo.
Kev taw qhia txog cov txheej txheem ntawm tsoomfwv.FDA thiab NIOSH yuav tsum pom zoo rau cov ntaub npog qhov ncauj phais thiab cov ntaub npog ua pa. Vim tias cov no yog cov koom haum tsoomfwv, qhov no tuaj yeem yog ib qho txheej txheem ntev, tshwj xeeb tshaj yog rau thawj lub tuam txhab uas tsis tau dhau los ntawm cov txheej txheem ua ntej. Tsis tas li ntawd, yog tias muaj dab tsi tsis raug thaum lub sijhawm tsoomfwv pom zoo, lub tuam txhab yuav tsum pib dua. Txawm li cas los xij, cov tuam txhab uas twb muaj cov khoom zoo sib xws dhau los ntawm cov txheej txheem tuaj yeem ua raws li lawv txoj hauv kev los ntawm kev pom zoo yav dhau los kom txuag lub sijhawm thiab kev ua haujlwm.
Paub txog cov qauv uas yuav tsum tau tsim cov khoom.Cov chaw tsim khoom yuav tsum paub txog kev sim uas cov khoom yuav dhau mus kom lawv thiaj li ua tau zoo ib yam thiab xyuas kom meej tias nws muaj kev nyab xeeb rau tus neeg siv kawg. Qhov xwm txheej phem tshaj plaws rau cov chaw tsim khoom kev nyab xeeb yog kev rov qab hu dua vim nws ua rau lawv lub koob npe puas tsuaj. Cov neeg siv khoom PPE tuaj yeem nyuaj rau nrhiav vim lawv feem ntau siv cov khoom uas tau lees paub lawm, tshwj xeeb tshaj yog thaum nws txhais tau tias lawv lub neej nyob ntawm txoj kab.
Kev sib tw tawm tsam cov tuam txhab loj.Tau kaum xyoo dhau los no, cov tuam txhab me me hauv kev lag luam no tau raug yuav thiab sib sau ua ke ua cov tuam txhab loj dua xws li Honeywell. Cov ntaub npog qhov ncauj phais thiab cov khoom siv ua pa yog cov khoom tshwj xeeb uas cov tuam txhab loj dua uas muaj kev paub hauv thaj chaw no tuaj yeem tsim tau yooj yim dua. Ib feem ntawm qhov yooj yim no, cov tuam txhab loj dua kuj tuaj yeem ua rau lawv pheej yig dua, thiab yog li ntawd muab cov khoom lag luam ntawm tus nqi qis dua. Tsis tas li ntawd, cov polymers siv hauv kev tsim cov ntaub npog qhov ncauj feem ntau yog cov mis tshwj xeeb.
Kev Tshawb Fawb Txog Tsoom Fwv Txawv Teb ChawsRau cov chaw tsim khoom uas xav muag rau cov neeg yuav khoom Suav tom qab muaj kev sib kis kab mob coronavirus xyoo 2019, lossis qhov xwm txheej zoo sib xws, muaj cov kev cai lij choj thiab cov koom haum tsoomfwv uas yuav tsum tau ua raws li.
Tau txais cov khoom siv.Tam sim no muaj cov khoom siv npog ntsej muag tsis txaus, tshwj xeeb tshaj yog cov ntaub uas yaj. Ib lub tshuab yaj yuav siv sijhawm ntau lub hlis los ua thiab teeb tsa vim nws xav tau los tsim cov khoom zoo heev. Vim li no nws nyuaj rau cov chaw tsim khoom ntaub yaj kom nthuav dav, thiab qhov kev thov loj heev thoob ntiaj teb rau cov ntaub npog ntsej muag ua los ntawm cov ntaub no tau ua rau muaj kev tsis txaus thiab nqi nce siab.
