Puas yog UVC Safe?

Puas yog UVC Safe?

Sib sib zog nqus ultraviolet (UVC) lub teeb emitting diodes (LEDs) yog qhov chaw ntawm hluav taws xob thiab yuav tsum tau siv yam xyuam xim. Cov ntaub ntawv ntawm nplooj ntawv no yog tsim los rau cov neeg siv paub txog lub xeev kev paub txog qee qhov kev ceev faj thiab kev coj ua uas nquag qhia hauv cov ntaub ntawv ntawm UV irradiation qhov chaw (cov ntsiab lus ntxiv muaj nyob rau hauv daim ntawv thov no). Nws tsis yog npaj los muab kev txheeb xyuas meej ntawm qhov kev kawm.

Hais txog UVC ib puag ncig kev noj qab haus huv thiab kev nyab xeeb, tsis muaj ib qho chaw ua haujlwm ntsig txog cov cai thiab cov cai tam sim no tsim los ntawm Lub Koom Haum Ua Haujlwm Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA).

UV Teeb Qhov cuam tshuam rau kev noj qab haus huv

Los ntawm 10 nm mus rau 400 nm yog thaj tsam UV ntawm electromagnetic zog spectrum. UV hluav taws xob tuaj yeem raug mob ntawm daim tawv nqaij thiab ob lub qhov muag nyob ntawm lub wavelength thiab ntev ntawm kev raug.

Plaub ntu ua rau UV spectrum:

UVA (315-400 nanometers)
UVB (280-315 nanometers)
UVC (200-280 nanometers)
UV Nqus Tsev (nruab nrab ntawm 100 txog 200 nm)

Cov hluav taws xob ntau dua thiab ntau lub zog ntawm ib photon yog txuam nrog kev txo wavelength.

UV teeb qhov cuam tshuam rau cov khoom muaj sia

Txawm hais tias UVB hluav taws xob tau paub zoo txog nws qhov kev puas tsuaj rau tib neeg cov tawv nqaij thiab kev sib raug zoo rau cov qog nqaij hlav ntawm daim tawv nqaij, txhua qhov ntawm UV bands - UVA, UVB, thiab UVC - nthuav tawm cov kev pheej hmoo tshwj xeeb rau tib neeg.

UVC hluav taws xob txhais tau hais tias muaj wavelengths nyob rau hauv 280 nm. Peb cov huab cua absorbs tag nrho cov wavelengths, yog li tsis muaj UVC hluav taws xob mus txog lub ntiaj teb nto. Cov wavelengths no nkag tau los ntawm tib neeg tsim qhov chaw xws li UVC LEDs.

Thaum nws tau dhau qhov ntev ntawm qhov tawg, qhov kev siv los ntawm cov ntsiab lus xws li UVC LEDs txo qis exponentially. Nws txo qis li 1 tshaj qhov square ntawm qhov deb. Qhov no txhais tau hais tias 1) tus nqi ntawm UVC hluav taws xob ib tus neeg tau txais nyob ntawm seb qhov chaw nyob ze rau nws li cas, thiab 2) vim tias tib neeg cov tawv nqaij nqus tau ntev heev, UVC hluav taws xob tsawg heev tuaj yeem ncav cuag cov tawv nqaij ntawm lub cev. Hloov chaw, tag nrho cov kev nqus tau tshwm sim hauv cov txheej txheem ntawm tes tuag.

Tsis tshua muaj, ntev ntev raug rau UVC hluav taws xob tuaj yeem ua rau lub qhov muag thiab tawv nqaij puas tsuaj ib ntus, xws li pob txha raug mob (tseem hu ua "welder's eye"), tab sis cov xwm txheej no feem ntau daws lawv tus kheej hauv ob peb hnub. Yog li ntawd, kev tiv thaiv ntawm daim tawv nqaij (tshwj xeeb yog qhib qhov txhab) thiab, qhov tseem ceeb tshaj plaws, lub qhov muag los ntawm UVC hluav taws xob yog qhia thaum siv UVC LEDs.

Koj tuaj yeem pom ntawm no cov lus pom zoo txog kev nyab xeeb rau kev siv UVC los ntawm EU lub koom haum saib xyuas kev noj qab haus huv. Txoj kev tshawb nrhiav pom tshwj xeeb tias:

Txawm li cas los xij, UVC muaj zog heev los ntawm chromophores nyob rau hauv lub Upper epidermis (Young, 1997) thiab UVC-induced DNA puas nyob rau hauv lub basal txheej ntawm tib neeg epidermis yog tsis yooj yim nrhiav tau (Campbell li al, 1993; Chadwick li al, 1995), uas. tej zaum yuav piav qhia yog vim li cas qhov koob tshuaj tiv thaiv kab mob rau UVC erythema hauv tib neeg daim tawv nqaij yog qhov qis dua rau UVB (Diffey thiab Farr, 1991). UVC los ntawm cov khoom siv dag zog tsis zoo li yuav ua rau muaj kev pheej hmoo luv luv lossis ntev rau tib neeg cov tawv nqaij. Tab sis UVC tej zaum yuav ua rau mob photokeratitis ... UVC raug los ntawm ib qho khoom siv tanning yuav tsum tsis txhob raug tso cai vim tias nws tsis zoo li yuav ua rau mob hnyav lossis ntev mus ntev rau daim tawv nqaij tab sis tuaj yeem ua rau lub qhov muag loj heev.

Tib txoj kev tshawb nrhiav pom qhov tsawg kawg nkaus kev noj qab haus huv thiab kev nyab xeeb cov cai (2006/25/EC) rau cov neeg ua haujlwm raug kev phom sij los ntawm cov hluav taws xob hluav taws xob hluav taws xob, txawm tias rau txhua qhov UV bands ua ke: "Kev txwv qhov nqi rau UV (180-400nm) yog 30 J/m2 (= txhua hnub tus nqi ntawm 8h)"

Daim tawv nqaij nyhuv ntawm UVC

Kev mob hnyav (lub sij hawm luv luv) tej zaum yuav ua rau daim tawv nqaij liab los yog ua rau mob. Cov kub hnyiab no yuav hnyav heev yog tias tau raug ntau heev. Kuj tseem muaj kev pheej hmoo ntau ntxiv rau qhov raug mob ntev (ntev), uas yog raws li tag nrho lub neej raug. Kev sib kis loj loj ua rau muaj kev phom sij ntev rau ntawm daim tawv nqaij thiab kev laus ntawm daim tawv nqaij.

UV hluav taws xob los ntawm Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE) tau yooj yim nqus los ntawm cov ntaub ntawv xws li khaub ncaws, yas, thiab iav. UV hluav taws xob tsis ua haujlwm ntxiv lawm thaum nws tau nqus. Txhawm rau tiv thaiv txhua qhov chaw raug thaum ua haujlwm nrog qhib UV hluav taws xob thaum tu, kev pabcuam, lossis lwm yam xwm txheej, cov cuab yeej tiv thaiv tus kheej raug qhia. Ua haujlwm ze UVC cov cuab yeej xav tau ib qho:

Siv lub ntsej muag puv lossis UV thaiv qhov ncauj qhov ntswg.

Nws raug nquahu kom hnav tsom iav kev nyab xeeb nrog lub ntsej muag qhwv ib ncig kom tiv thaiv sab nraud vim cov tsom iav thiab tsom iav tsis tu ncua tsis thaiv lub qhov muag los ntawm UV hluav taws xob.

Siv cov tsho loj, hnab looj tes nitrile, lossis lwm yam khaub ncaws hauv chav kuaj los npog cov tawv nqaij uas raug.

Tsim, tswj, saib xyuas, thiab kev saib xyuas kev nyab xeeb

Los ntawm cov khoom tsim kev nyab xeeb tsim kev xav thiab tswj, UVC raug txo qis. Piv txwv li, kev ruaj ntseg keyboards wired nyob rau hauv series pab kom tig-tawm ntawm UVC qhov chaw yam tsis muaj kev cuam tshuam cov neeg ua hauj lwm rau UV teeb. Xwb, tso ON / OFF keyboards rau UVC lub teeb ci hauv qhov chaw uas tsuas yog siv tau rau cov neeg tau txais kev tso cai. Txhawm rau tiv thaiv UVC qhov chaw los ntawm kev tsis txhob txwm qhib, hloov chaw yuav tsum raug kaw lossis tiv thaiv tus password. Lub chaw saib xyuas yuav tsum yog qhov kev xaiv rau txhua qhov UVC system kom cov neeg ua haujlwm tuaj yeem tshawb xyuas lub teeb sib dhos yam tsis muaj kev pheej hmoo ntawm UVC ntau dhau.

Kev tiv thaiv overexposure tuaj yeem tiv thaiv nrog kev pab cuam ntawm kev teeb tsa kom zoo, kev saib xyuas, kev cob qhia rau cov neeg ua haujlwm tu, kos npe, thiab siv cov keyboards kev nyab xeeb. Txhawm rau txo qhov kev pheej hmoo tsawg, nws raug nquahu kom khaws UV system phau ntawv ua haujlwm thiab cov lus pom zoo rau kev siv ntawm tes. Qhov ntsuas kub thiab qhov txheeb ze ntawm qhov ntsuas tau teev tseg los ntawm kev tsim qauv yuav tsum suav nrog rau cov neeg ua haujlwm lossis cov neeg ua haujlwm saib xyuas kom pom tseeb txhawm rau ua kom muaj kev nyab xeeb. Hluav taws xob yuav tsum tau muab tua tas li kom tsis txhob muaj qhov tshwm sim tsis zoo. Kev tu yuav tsum tau ua raws li cov neeg tsim khoom cov lus qhia. Thaum muaj kev lag luam UV saib uas tuaj yeem ntes cov khoom tawm lossis xau, tsis muaj cov qauv tsim los saib xyuas cov khoom siv UV.

Adaptation rau UV raug

Cov teebmeem ntawm qhov raug mob UV hluav taws xob feem ntau yog me me, thiab ntau cov tsos mob yuav siv sij hawm los tshwm sim. Cov kauj ruam hauv qab no tau qhia thaum raug UV:

Nrog rau ophthalmologist yog tias koj xav tias qhov muag puas.

Daim tawv nqaij mob sai li sai tau

Saib xyuas cov txheej txheem qhia txog xwm txheej EHS rau koj lub tuam txhab. Cov no feem ntau xav tau cov ntaub ntawv ntawm qhov xwm txheej hnub tim thiab lub sijhawm, cov neeg koom, khoom siv, thiab hom kev raug mob.
