Ibengineering tswj ntsuas kev nyab xeeb laserhais txog lub cev lossis kev tsim qauv tsim ua rau hauv lub tshuab laser lossis nws ib puag ncig rautxo lossis tshem tawm qhov raug rau cov hluav taws xob lasertsis tso siab rau tib neeg tus cwj pwm los yogCov khoom siv tiv thaiv tus kheej (PPE). Cov kev tswj hwm no suav hais tias yog txheej txheej tiv thaiv zoo tshaj plaws hauv hierarchy ntawm kev tswj hwm kev phom sij.
Common Engineering Control Measures rau Laser Safety:
Enclosures (Interlocked Protective Housing)
Txoj kev laser beam yog tag nrho nyob rau hauv ib qho kev tiv thaiv vaj tse uas tiv thaiv kev nkag tau thaum lub sijhawm ua haujlwm.
Yog tias lub qhov rooj qhib, ib qhointerlock system cia li lov tes tawlub laser los yog txo nws mus rau theem kev nyab xeeb.
Beam Stops thiab Attenuators
Cov cuab yeej muab tso rau ntawm qhov kawg ntawm txoj kab nqaj kom nyab xeeb nqus lossis thaiv cov hluav taws xob tsis siv laser.
Tiv thaiv kom tsis txhob muaj kev cuam tshuam los yog cuam tshuam cov kab teeb ntawm kev mus dhau qhov chaw ua haujlwm.
Ntsiab -Controlled Power Switch
Ib qho tseem ceeb tshem tau tiv thaiv tsis tau tso cai los yog ua kom yuam kev ntawm lub tshuab laser.
Tej thaj chaw deb Interlock Connector
Tso cai rau kev txuas mus rau qhov chaw nres tsheb thaum muaj xwm ceev, tswj kev nkag mus hauv chav, lossis teeb ceeb toom kom kaw lub laser yog tias muaj kev nyab xeeb ua txhaum cai.
Qhov cua thiab Fume Extraction Systems
Tshwj xeeb tshaj yog tseem ceeb nyob rau hauv laser txiav, engraving, los yog cov txheej txheem kho mob qhov twg cov kev sib tshuam ntawm lub nqaj nrog cov khoom ua rau muaj kev phom sij rau cov pa paug (xws li laser-tsim cov pa paug los yog LGACs).
Tsau lossis kho tau Beam Path Enclosures
Tubes, shrouds, los yog cov teeb meem nyob ib ncig ntawm lub beam txoj kev kom muaj reflections thiab txwv qhov chaw raug.
Tsis siv neeg kaw -Off lossis Emission qeeb
Lub laser tsuas emissions tom qab preset ncua sij hawm los yog nyob rau hauv ib tug tshwj xeeb sensor- pom zoo tej yam kev mob, txo kev pheej hmoo thaum teeb.
Kev ceeb toom Systems koom nrog kev ua haujlwm
Cov ntsuas pom tau los yog pom tau (piv txwv li, "Laser On" teeb) uas qhib tau thaum lub laser energized.
Vim li cas Engineering tswj qhov teeb meem
Raws li cov qauv kev nyab xeeb xws liANSI Z136.1 (Kev Nyab Xeeb Siv Lasers)thiabIEC 60825 (TSI), engineering controls are prioritized over administrative controls (xws li, kev cob qhia) thiab PPE (xws li, laser tsom iav) vim tias lawv:
Ua haujlwmtxiav txim,
Yogtsis nyob ntawm tus neeg siv kev ua raws cai,
Muabzoo ib yam, txhim khu kev qha tiv thaiv.
Piv txwv li, nyob rau hauv chav kawm 4 laser chaw ua haujlwm, txawm tias tus neeg teb xov tooj tsis nco qab hnav tsom iav kev nyab xeeb, lub kaw lus sib cuam tshuam zoo tuaj yeem tiv thaiv tau tag nrho.
Cov ntsiab lus
Engineering tswj yog ua - nyob rau hauv kev nyab xeeb ntauas lub cev cais tawm, thaiv, lossis tswj cov teeb meem laser ntawm qhov chaw. Lawv tsim lub hauv paus ntawm kev muaj zoglaser kev nyab xeebqhov kev pab cuam thiab yog qhov tseem ceeb rau kev ua raws li txoj cai kev noj qab haus huv thiab kev nyab xeeb hauv kev lag luam, kev kho mob, thiab kev tshawb fawb.
