1. Ngaphakathi kwegumbi elihlanzekile, izinhlobo ezahlukene zamakamelo okugcina nokusabalalisa amakhemikhali kufanele zimiswe ngokusekelwe ezidingweni zenqubo yokukhiqiza umkhiqizo kanye nezakhiwo zomzimba nezamakhemikhali zamakhemikhali. Amapayipi kufanele asetshenziswe ukuhlinzeka ngamakhemikhali adingekayo emishinini yokukhiqiza. Amakamelo okugcina nokusabalalisa amakhemikhali ngaphakathi kwegumbi elihlanzekile ngokuvamile atholakala endaweni yokukhiqiza esekelayo, ngokuvamile phansi kwesakhiwo esinesitezi esisodwa noma esinezitezi eziningi, eduze kodonga lwangaphandle. Amakhemikhali kufanele agcinwe ngokwezakhiwo zawo zomzimba nezamakhemikhali. Amakhemikhali angahambisani kufanele abekwe emakamelweni okugcina nokusabalalisa amakhemikhali ahlukene, ahlukaniswe yizingxenye eziqinile. Amakhemikhali ayingozi kufanele agcinwe emakamelweni okugcina noma okusabalalisa ahlukene anesilinganiso sokumelana nomlilo okungenani amahora angu-2.0 phakathi kwamakamelo aseduze. Lawa makamelo kufanele abekwe ekamelweni esitezi sokuqala sesakhiwo sokukhiqiza, eduze kodonga lwangaphandle.
2. Amakamelo ahlanzekile embonini ye-elekthronikhi avame ukuba namakamelo okugcina nokusabalalisa ama-asidi nama-alkali, kanye namakamelo okususa izinto ezivuthayo. Amakamelo okugcina nokusabalalisa ama-asidi avame ukuba nezinhlelo zokugcina nokusabalalisa ama-sulfuric acid, i-phosphoric acid, i-hydrofluoric acid, kanye ne-hydrochloric acid. Amakamelo okugcina nokusabalalisa ama-alkali avame ukuba nezinhlelo zokugcina nokusabalalisa ama-sodium hydroxide, i-hydroxide cake, i-ammonium hydroxide, kanye ne-tetramethylammonium hydroxide. Amakamelo okugcina nokusabalalisa ama-solvent avuthayo avame ukuba nezinhlelo zokugcina nokusabalalisa ama-solvent e-organic njenge-isopropyl alcohol (IPA). Amakamelo ahlanzekile ezitshalweni zokukhiqiza ama-wafer e-circuit ehlanganisiwe nawo anamagumbi okugcina nokusabalalisa ama-slurry acwebezelayo. Amakamelo okugcina nokusabalalisa amakhemikhali avame ukuba sezindaweni zokukhiqiza noma zokusekela eziseduze noma eduze kwezindawo zokukhiqiza ezihlanzekile, ngokuvamile esitezi sokuqala lapho kufinyelela ngqo ngaphandle.
3. Amakamelo okugcina nokusabalalisa amakhemikhali afakwe imiphongolo yokugcina noma amathangi anezikhwelo ezahlukene ngokusekelwe kuhlobo, ubuningi, kanye nezici zokusetshenziswa kwamakhemikhali adingekayo ekukhiqizweni komkhiqizo. Ngokwezindinganiso nemithethonqubo, amakhemikhali kufanele agcinwe ngokwehlukana futhi ahlukaniswe. Umthamo wemiphongolo noma amathangi asetshenziswayo kufanele wanele ukusetshenziswa kwamakhemikhali izinsuku eziyisikhombisa. Imiphongolo noma amathangi ansuku zonke kufanele futhi ahlinzekwe, enomthamo owanele ukumboza ukusetshenziswa kwamakhemikhali amahora angama-24 adingekayo ekukhiqizweni komkhiqizo. Amakamelo okugcina nokusabalalisa izinyibilikisi ezivuthayo namakhemikhali akhipha i-oxidizing kufanele ahlukaniswe futhi ahlukaniswe namakamelo aseduze ngodonga oluqinile olungashisi umlilo olunesilinganiso sokumelana nomlilo samahora angu-3.0. Uma etholakala esitezi sokuqala sesakhiwo esinezitezi eziningi, kufanele ahlukaniswe kwezinye izindawo ngezitezi ezingashisi ezinomlinganiselo wokumelana nomlilo okungenani amahora angu-1.5. Igumbi lokulawula eliphakathi nendawo lokuphepha kwamakhemikhali nohlelo lokuqapha ngaphakathi kwegumbi elihlanzekile kufanele libekwe ekamelweni elihlukile.
4. Ukuphakama kwamakamelo okugcina nokusabalalisa amakhemikhali ngaphakathi kwegumbi elihlanzekile kufanele kunqunywe ngokusekelwe ezidingweni zokuhlelwa kwemishini namapayipi futhi ngokuvamile akufanele kube ngaphansi kwamamitha angu-4.5. Uma kutholakala endaweni yokukhiqiza esekelayo yegumbi elihlanzekile, ukuphakama kwegumbi lokugcina nokusabalalisa amakhemikhali kufanele kuhambisane nokuphakama kwesakhiwo.
