1. Nyob rau hauv chav tsev huv si, cov chav sib txawv ntawm cov khoom siv tshuaj thiab cov chaw faib khoom yuav tsum tau teeb tsa raws li cov txheej txheem tsim khoom thiab cov khoom siv tshuaj lom neeg lub cev thiab tshuaj lom neeg. Cov kav dej yuav tsum tau siv los muab cov tshuaj xav tau rau cov khoom siv ntau lawm. Cov chaw khaws tshuaj thiab cov chaw faib khoom hauv chav huv si feem ntau yog nyob rau hauv qhov chaw pabcuam tsim khoom, feem ntau nyob rau hauv pem teb ntawm ib-zaj dab neeg lossis ntau zaj dab neeg, nyob ze ntawm phab ntsa sab nrauv. Cov tshuaj yuav tsum tau khaws cia nyias raws li lawv lub cev thiab tshuaj. Cov tshuaj tsis sib xws yuav tsum tau muab tso rau hauv cov chaw khaws tshuaj thiab faib khoom cais, sib cais los ntawm cov khoom sib cais. Cov tshuaj phom sij yuav tsum tau muab cia rau hauv cov chav sib cais lossis chav faib khoom nrog qhov ntsuas hluav taws kub tsawg kawg 2.0 teev ntawm cov chav nyob ib sab. Cov chav no yuav tsum nyob rau hauv ib chav nyob rau hauv thawj pem teb ntawm lub tsev tsim khoom, nyob ze ntawm phab ntsa sab nrauv.
2. Cov chav huv huv hauv kev lag luam hluav taws xob feem ntau muaj chav cia thiab faib cov kua qaub thiab alkalis, nrog rau cov kuab tshuaj tua hluav taws. Acid cia thiab faib chav tsev feem ntau hauv tsev cia khoom thiab faib tshuab rau sulfuric acid, phosphoric acid, hydrofluoric acid, thiab hydrochloric acid. Alkali cia thiab faib chav tsev feem ntau hauv tsev cia thiab faib tshuab rau sodium hydroxide, hydroxide ncuav mog qab zib, ammonium hydroxide, thiab tetramethylammonium hydroxide. Flammable solvent cia thiab faib chav tsev feem ntau hauv tsev cia thiab faib tshuab rau cov kuab tshuaj organic xws li isopropyl cawv (IPA). Cov chav huv huv hauv kev sib xyaw ua ke wafer fabrication nroj tsuag kuj muaj polishing slurry cia thiab faib chav. Chemical cia thiab faib chav tsev feem ntau yog nyob rau hauv pab tsim khoom los yog kev txhawb nqa cheeb tsam nyob ze los yog nyob ib sab ntawm cov chaw tsim khoom huv si, feem ntau nyob rau hauv pem teb nrog ncaj qha mus rau sab nraum zoov.
3. Chemical cia thiab faib cov chav tsev yog nruab nrog cov thoob khib nyiab los yog lub tank sib txawv raws li hom, kom muaj nuj nqis, thiab kev siv cov yam ntxwv ntawm cov tshuaj uas yuav tsum tau ua rau kev tsim khoom. Raws li cov qauv thiab cov kev cai, cov tshuaj yuav tsum tau muab cais thiab cais. Lub peev xwm ntawm cov thoob los yog cov tso tsheb hlau luam siv yuav tsum txaus rau xya hnub kev noj cov tshuaj. Txhua hnub cov thoob lossis cov tso tsheb hlau luam yuav tsum tau muab, nrog lub peev xwm txaus los npog 24-teev kev siv tshuaj uas xav tau rau kev tsim khoom. Kev khaws cia thiab faib chav rau cov kuab tshuaj flammable thiab cov tshuaj oxidizing yuav tsum tau muab cais tawm thiab sib cais los ntawm cov chav uas nyob ib sab los ntawm cov phab ntsa uas muaj hluav taws kub-resistant nrog qhov ntsuas hluav taws kub ntawm 3.0 teev. Yog hais tias nyob rau hauv thawj pem teb ntawm ib tug ntau-zaj dab neeg lub tsev, lawv yuav tsum tau muab cais los ntawm lwm qhov chaw los ntawm cov uas tsis yog-combustible plag tsev nrog ib tug hluav taws kub ntsuas ntawm tsawg kawg yog 1.5 teev. Lub hauv paus tswj kev tswj cov tshuaj lom neeg kev nyab xeeb thiab kev saib xyuas hauv chav huv huv yuav tsum nyob hauv ib chav cais.
4. Qhov siab ntawm cov khoom siv tshuaj thiab cov khoom faib tawm hauv chav huv huv yuav tsum tau txiav txim siab raws li cov khoom siv thiab cov kav dej layout yuav tsum thiab feem ntau yuav tsum tsis pub tsawg tshaj 4.5 meters. Yog hais tias nyob rau hauv qhov chaw pab tsim khoom ntawm chav huv huv, qhov siab ntawm cov khoom siv tshuaj thiab chav faib khoom yuav tsum ua raws li qhov siab ntawm lub tsev.
