Yuav Ua Li Cas Txhim Kho Laboratory Laser Safety Protection?

Kab lus no suav nrog cov txheej txheem ntawmLaser Kev Tiv Thaiv Kev Nyab Xeebnyob rau hauv lub tsev kawm ntawv lub chaw soj nstuam, nrog rau cov qauv tsim thiab layout ntawm laser ceeb toom cov cim, kev xaiv ntawm laser kev ruaj ntseg cov cuab yeej, tshwj xeeb tshaj yog xaiv thiab siv cov laser kev ruaj ntseg tsom iav.

Engineering Control
Kev tswj xyuas engineering yog hais txog kev ntsuas kev nyab xeeb ntawm cov qauv ntawm lub laser qhov chaw thiab cov txheej txheem ntawm kev xa tawm thiab tsom rau cov kab teeb ci laser, feem ntau suav nrog: kev tiv thaiv npog, baffle thiab kev ruaj ntseg interlock, kev nyab xeeb kho qhov muag txoj kev, beam terminator, thiab lwm yam. hais txog txoj kev kho qhov muag uas kaw cov hluav taws xob laser uas yuav ua rau combustion los yog lwm yam hluav taws xob, thiab ib qho kev tiv thaiv npog thiab cov cuab yeej tswj yuav tsum tau nruab rau ntawm txhua lub tshuab laser. Beam stoppers lossis attenuators tuaj yeem siv los tiv thaiv lub teeb laser los ntawm kev ncua dhau ntawm thaj chaw ua haujlwm. Txhua lub tshuab laser uas muaj nyob rau hauv chav kawm 3B thiab 4 yuav tsum muaj ib lossis ntau dua cov khoom siv hluav taws xob ntxiv mus tas li.

Kev Tiv Thaiv Tus Kheej
Cov khoom siv tiv thaiv tus kheej muaj xws li tsom iav, tiv thaiv khaub ncaws thiab hnab looj tes tiv thaiv. Rau cov neeg ua haujlwm uas tuaj yeem raug hluav taws xob ntau dhau ntawm qhov Maximum Permissible Exposure (MPE) rau ntawm daim tawv nqaij, cov khaub ncaws tiv thaiv tsim nyog yuav tsum tau muab rau qhov twg los tau. Cov khaub ncaws tiv thaiv laser feem ntau yog ua los ntawm cov khoom siv hluav taws kub-resistant thiab kub-resistant thiab npog tag nrho cov tawv nqaij. Laser tsom iav kev nyab xeeb tuaj yeem tiv thaiv lossis txo cov laser puas rau tib neeg lub qhov muag, thiab yog ib yam ntawm cov tsom iav zoo thiab muaj kev nyab xeeb. Cov hauv qab no yog cov ncauj lus kom ntxaws qhia txog cov ntsiab lus tseem ceeb thiab hom laser tiv thaiv cov ntaub ntawv thiab xaiv cov iav tiv thaiv.

Cov ntaub ntawv pov thawj Laser
Tus yuam sij rau cov khoom siv tiv thaiv laser yog cov ntaub ntawv tiv thaiv laser, thiab nws cov cim tseem ceeb suav nrog:
(1) Lub laser wavelength tsom los ntawm cov khoom tiv thaiv, uas yog, tiv thaiv wavelength;
(2) Optical density (OD), uas ntsuas cov hluav taws xob laser ntawm qhov kev tiv thaiv wavelength
Lub cev kom muaj nuj nqis ntawm cov degree ntawm attenuation ntawm lub zog, cov mis laij lej ntawm optical ntom yog
OD =log₁₀(1 / T_λ) =log₁₀(I_i/I_t), qhov twg T_λyog lub laser transmittance ntawm kev tiv thaiv wavelength, I_iyog qhov xwm txheej laser siv, I_tyog qhov tawm laser siv;
(3) Pom pom lub teeb xa hluav taws xob (VLT), uas cuam tshuam rau tus neeg siv qhov kev soj ntsuam ntawm ib puag ncig ib puag ncig;
(4) Lub kaum sab xis saib ntawm lub laser tiv thaiv, uas yog, lub kaum sab xis tiv thaiv;
(5) Qhov tsawg kawg nkaus lub zog ntawm lub zog yuav tsum tau ua rau cov khoom puas tsuaj, uas yog, qhov pib puas tsuaj;
(6) Lub sijhawm luv tshaj plaws uas cov khoom siv tuaj yeem ua lub luag haujlwm tiv thaiv tom qab raug irradiated los ntawm laser, uas yog, lub sij hawm teb.

Muaj ntau hom laser tiv thaiv cov ntaub ntawv, thiab cov ntsiab lus tseem ceeb yog raws li hauv qab no: absorbing cov ntaub ntawv tiv thaiv, cov ntaub ntawv tiv thaiv kev xav, cov ntaub ntawv tiv thaiv sib xyaw, cov ntaub ntawv tiv thaiv coherent thiab cov ntaub ntawv tiv thaiv holographic. Laser kev tiv thaiv cov ntaub ntawv yog tsim nyob rau hauv cov kev taw qhia ntawm multi-band kev tiv thaiv, nthuav lub kaum sab xis tiv thaiv, thiab ua kom pom lub teeb transmittance.

Laser Safety Glasses
Tam sim no, cov khoom tseem ceeb ntawm laser tiv thaiv cov ntaub ntawv paub tab siv nyob rau hauv laser tiv thaiv tsom iav yog hom nqus, hom kev xav thiab hom sib xyaw. Absorbing tiv thaiv cov ntaub ntawv yog tsuas yog tov nrog ib tug nruab nrab uas absorbs lub teeb ntawm ib tug tshwj xeeb wavelength nyob rau hauv lub lens kom txo tau lub teeb transmittance ntawm lub wavelength tiv thaiv. Vim nws hnav tsis kam, kev tiv thaiv lub kaum sab xis loj thiab tus nqi qis, nws tau dhau los ua qhov tseem ceeb tam sim no. coj mus muag laser kev ruaj ntseg tsom iav khoom. Ntxiv cov khoom sib txawv sib txawv nrog cov kev nqus dej muaj zog ntawm cov yoj tshwj xeeb rau polycarbonate lossis iav tuaj yeem tsim cov iav tiv thaiv laser uas tuaj yeem tiv thaiv ntau lub yoj bands.

Thaum xaiv cov tsom iav tiv thaiv laser, koj yuav tsum tau xyuam xim rau cov ntsiab lus hauv qab no:
(1) Xaiv qhov kev tiv thaiv wavelength uas tsim nyog, thiab xaiv cov iav tiv thaiv laser nrog cov hlua tiv thaiv raws li lub laser;
(2) Xaiv cov qib kev tiv thaiv laser tsim nyog. Rau cov tsis-chav kawm 4 lasers, feem ntau xaiv laser tiv thaiv iav nrog ib tug OD nqi ntawm 4 thiab saum toj no. Yog tias nws yog chav kawm 4 laser, xaiv cov iav tiv thaiv laser nrog tus nqi OD ntau dua rau cov khoom sib txuas;
(3) Xaiv lub teeb pom kev zoo, yog tias pom lub teeb pom kev tsawg dhau, nws yuav cuam tshuam rau kev soj ntsuam ntawm ib puag ncig ib puag ncig. Feem ntau, cov tsom iav tiv thaiv yog tsom rau qee qhov wavelength, thiab ib lub lens yuav tsum tsis txhob siv rau ntau lub hom phiaj.

Lwm yam khoom siv tiv thaiv Laser
Lub laser tiv thaiv screen lossis laser tiv thaiv kab hlau rhuav tuaj yeem muab tso rau hauv thaj chaw ib puag ncig lub laser. Nws nto feem ntau muaj lub teeb dub-absorbing txheej los nqus cov emission lossis reflected laser thiab tiv thaiv ntau qhov kev xav ntawm lub laser los ntawm kev ua rau muaj teeb meem.
nrog rau foreseeable txim. Hais lus nruj me ntsis, lub zog loj lasers tuaj yeem tawm lub teeb tsuas yog nyob rau hauv qhov chaw kaw. Feem ntau qhov chaw tiag tiag tsis raug kaw. Hnav cov khaub ncaws tiv thaiv kom tsis txhob muaj kev puas tsuaj los ntawm cov hluav taws xob hluav taws xob siab hluav taws xob tawg.

Laser Warning Sign
Cov khoom lag luam laser uas muaj qib sib txawv yuav tsum tau tshaj tawm cov cim ceeb toom sib xws. Cov cim ceeb toom yuav tsum tau muab tso rau sab nraum lub laser tswj cheeb tsam lossis ntawm qhov nkag ntawm chav kuaj kom ceeb toom txog kev phom sij ua ntej. Lub laser ceeb toom kos npe muaj cov cim ceeb toom thiab ib qho kev piav qhia. Lub thav duab ntawm daim duab ceeb toom yog daim duab peb sab sib npaug, qhov nruab nrab yog lub voj voog concentric radiating rau ib puag ncig, cov ncej thiab cov cim yog xim dub, thiab keeb kwm yav dhau yog daj. Cov ciam teb ntawm cov lus piav qhia yog ib daim duab plaub nrog cov lus piav qhia sab hauv, raws li pom hauv daim duab 1. Cov lus piav qhia cov cim tau muab faib ua laser cov khoom piav qhia cov cim, cov cim qhov rai, cov cim baffle, cov cim kev ruaj ntseg interlock, thiab lwm yam. Tsis tas li ntawd, ntxiv rau Chav Kawm. 1 cov khoom siv laser, cov khoom siv hluav taws xob thiab cov qauv piav qhia ntawm cov khoom siv laser yuav tsum tau txuas rau ntawm cov ntawv qhia lossis cov khoom siv laser, uas tuaj yeem suav nrog lub zog siab tshaj plaws ntawm lub laser, mem tes dav, emission wavelength, thiab cov khoom lag luam laser. Cov qauv raws li thiab hnub tshaj tawm, thiab lwm yam.

Laser cov khoom yuav tsum tau affixed nrog laser ceeb toom cim. Yog tias tsim nyog, ntau cov paib tuaj yeem muab tso tawm, suav nrog cov khoom siv laser ceeb toom, hluav taws xob qhov rai ceeb toom cov paib, baffle ceeb toom cov paib, thiab lwm yam. Cov ntawv qhia kev nyab xeeb yuav tsum tau muab tso rau hauv qhov chaw uas Class 3B thiab Class 4 cov khoom laser ua haujlwm. Cov cim ceeb toom yuav tsum tau muab tso rau qhov twg tib neeg lub qhov muag pom tau meej meej thiab qhov twg lawv yuav tsis raug mob los ntawm lub teeb laser. Hauv thaj chaw tiv thaiv laser mus tas li, cov paib ceeb toom yuav tsum tau teeb tsa ntawm qhov nkag thiab tawm. Ua lub luag haujlwm ceeb toom txaus ntshai tshaj plaws.

Hauv kev tswj hwm kev nyab xeeb ntawm laser, ua ntej ntawm tag nrho cov, nws yog ib qho tsim nyog los txhim kho kev paub txog kev nyab xeeb thiab kev tiv thaiv kev paub ntawm cov neeg siv laser, thiab ua tiav cov kev paub txog kev nyab xeeb tsim nyog thiab kev ntsuam xyuas nkag; thib ob, ua haujlwm zoo hauv laser engineering tswj chaw, tshaj tawm laser ceeb toom cov paib thiab piav qhia, thiab muab cov cuab yeej tiv thaiv tus kheej. khoom siv; Thaum kawg, cov kev siv laser thiab kev tswj xyuas yuav tsum tau tsim los tsim kom muaj kev sib koom ua ke thiab ua kom muaj kev nyab xeeb ua haujlwm zoo thiab txuas ntxiv txhim kho nrog cov kev hloov pauv hauv cov khoom thiab chaw ua haujlwm.
