Nyob rau niaj hnub no' kev tsim khoom lag luam zoo tshaj plaws, daim ntawv thov laser tau nthuav dav ntau dua, xws li laser vuam, tin soldering, txiav, cim, kos duab, kos duab, tu, thiab lwm yam Cia' sau qee qhov kev phiv tsim tawm hauv cov txheej txheem txheej txheem laser sib txawv, rau kev siv thiab ceeb toom. Nws vam tias feem ntau ntawm cov neeg siv khoom siv laser, EHS cov tuam tsev thiab cov thawj tswj hwm laus, cov khoom siv laser, thiab lwm yam.
1. Kev ua hlau
Hnyav hlau ua pa tau tsim thaum cov hlau ua tiav. Cov pa no tuaj yeem ua rau lub cev puas tsuaj thiab cov ntaub so ntswg ntawm tib neeg lub cev. Los ntawm qhov chaw soj ntsuam kho mob, tsawg kawg yog cov hlau hauv qab no thiab nws cov sib txuas tau cuam tshuam: manganese Mn, chromium Cr, nickel Ni, cobalt CO, txhuas Al, zinc Zn, tooj liab Cu, beryllium BE, lead Pb, thiab antimony Sb. Cov kev kho mob muaj xws li:
Tshuaj lom (CR + 6, MN),
Kev ua xua (Zn, Cu),
Pulmonary fibrosis (IB),
Carcinogenic (Cr -6, NIO), thiab ntxiv rau.
2. yas txiav
Ntau yam tshuaj muaj peev xwm txaus ntshai tuaj yeem tshwm sim thaum txiav cov yas. Thaum qhov ntsuas kub tsawg, cov aliphatic hydrocarbon tau tsim, thiab qhov kub tau siab, thiab cov ntxhiab tsw hydrocarbon (zoo li benzene, PAH) thiab polyhalide polycyclic hydrocarbon (xws li dioxidin, furan) tau nce. Qee yam tshuaj yuav ua rau cyanide, isocyanate (PU), acrylate (PMMA), thiab hydrogen peroxide (PVC). Cov kev kho mob muaj xws li:
3. Kev ua tej hub
Aluminium oxide Al2O3, magnesium Mg, calcium Ca thiab silicon Si oxide; oxide BEO (lom heev).
4. Wafer ua
Silicon Si thiab cov khib nyiab silica ntab hauv cov huab cua (tejzaum nws nqus cov nplooj ntsws tuaj yeem ua rau mob silicosis).
5. Txiav ntawv thiab ntoo
General cellulose byproducts, esters, acids, ethanol, benzene, thiab lwm yam.
