Cov cuab yeej tiv thaiv yuav tsum tau hnav thaum raug cov dej qab ntsev ntau ntau, thiab cov khaub ncaws ua haujlwm lossis lub kaus mom ua haujlwm yuav tsum yog cov paj rwb lossis cov khoom siv hluavtaws tsim nyog. Cov neeg ua haujlwm yuav tsum hnav khaub ncaws ua haujlwm, qhov ncauj qhov ntswg, tsom iav tiv thaiv, hnab looj tes roj hmab, roj hmab aprons, khau looj plab hlaub ntev thiab lwm yam khoom siv tiv thaiv kev ua haujlwm thaum ua haujlwm.
Ib qho tshuaj tsw qab thiab hydrophobic yuav tsum tau siv rau ntawm daim tawv nqaij. Thaum hu rau flake lossis granular caustic soda, qhov cua yuav tsum tau muab rau hauv qhov chaw ua haujlwm, thiab qhov siab tshaj plaws tso cai nyob rau hauv cov huab cua sab hauv tsev yog Tuam Tshoj MAC 0.5 mg / m3 (xws li NaOH) thiab American ACGIH TLVC 2 mg / m3 . Thaum koj tuaj yeem ntsib nrog nws cov plua plav, koj yuav tsum hnav lub hood-type powered air-purifying dust respirator. Thaum tsim nyog, hnav lub tshuab ua pa. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug nquahu kom tus neeg teb xov tooj hnav lub hood-hom hluav taws xob cua lim plua plav nqus pa, hnav roj hmab acid thiab alkali resistant khaub ncaws, thiab hnav roj hmab acid thiab alkali resistant hnab looj tes. Khaws kom deb ntawm cov khoom siv hluav taws xob thiab hluav taws kub. Tsis txhob tsim cov hmoov av. Tsis txhob sib cuag nrog cov kua qaub. Thaum tuav, nws yuav tsum maj mam thauj khoom thiab tshem tawm kom tsis txhob muaj kev puas tsuaj rau cov ntim thiab ntim. Nruab nrog cov khoom siv kho mob thaum muaj xwm ceev. Cov thawv khoob yuav ua rau muaj teeb meem seem. Thaum diluting los yog npaj cov kev daws teeb meem, lub hauv paus yuav tsum tau ntxiv rau hauv dej kom tsis txhob boiling thiab splashing. Hnav cov tsom iav thiab hnab looj tes tiv thaiv kom tsis txhob muaj qhov nchuav, cheb nws, hliv rau hauv cov dej ntau maj mam, yaug hauv av nrog dej, thiab muab cov dej phwj tso rau hauv cov dej khib nyiab. Yog tias cov lye kov cov tawv nqaij, nws tuaj yeem ntxuav nrog 5-10 feem pua magnesium sulfate tov; Yog hais tias nws splashes rau hauv lub qhov muag, nws yuav tsum tau ntxuav tam sim ntawd nrog ib tug loj npaum li cas ntawm boric acid aqueous tov; Neutralize nrog kua txiv kab ntxwv los yog txiv qaub kua txiv, haus qe dawb, mis nyuj los yog zaub roj thiab nrhiav kev kho mob tam sim ntawd. Emesis thiab gastric lavage yog contraindicated.
Cov khoom siv sodium hydroxide tuaj yeem ntim rau hauv 0.5 hli tuab steel nruas thiab kaw kom nruj, nrog rau qhov hnyav tsis tshaj 100kg; hnab yas los yog ob txheej kraft ntawv hnab nrog puv lossis nruab nrab qhib steel nruas; ntsia hlau-sab saum toj iav fwj, hlau hau iav fwj, yas hwj los yog hlau chim (cov kaus poom) sab nraum lub thawv ntoo zoo tib yam; ntsia hlau-sab saum toj iav fwj, lub raj mis yas los yog tin-plated sheet hlau chim (cov kaus poom) sab nraum cov thawv ntim hauv qab, cov thawv fiberboard lossis cov thawv plywood; tin-plated sheet hlau chim (cov kaus poom), hlau nruas (cov kaus poom), lub raj mis yas lossis hlau hoses sab nraum lub thawv corrugated. Lub thawv ntim khoom yuav tsum ua kom tiav thiab kaw, thiab yuav tsum muaj lub cim meej ""corrosive" . Thaum thauj los ntawm kev tsheb ciav hlau, steel nruas tuaj yeem thauj tau hauv gondolas. Kev ntim khoom yuav tsum ua kom tiav thiab qhov chaw thau khoom yuav tsum ruaj ntseg thaum lub sijhawm xa khoom. Thaum lub sij hawm kev thauj mus los, xyuas kom meej tias lub thawv tsis xau, tawg, poob, lossis puas, thiab tiv thaiv los ntawm ya raws thiab nag. Yog tias lub thawv ntim tau pom tias muaj xeb, tawg, qhov, melted thiab dripped, thiab lwm yam, lub ntim yuav tsum tau hloov tam sim ntawd los yog xa mus sai li sai tau, thiab lub thawv puas tuaj yeem kho tau los ntawm kev sib tsoo. Nws yog nruj me ntsis txwv tsis pub sib xyaw thiab thauj nrog cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob, cov kua qaub, cov tshuaj siv tau, thiab lwm yam. Lub tsheb thauj mus los yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev. Tsis txhob khaws thiab thauj ua ke nrog cov nplaim taws thiab cov kua qaub. Nyob rau hauv cov ntaub ntawv ntawm hluav taws kub, dej, xuab zeb thiab ntau yam hluav taws tua hluav taws yuav siv tau los tua hluav taws, tab sis cov neeg tua hluav taws yuav tsum xyuam xim rau cov corrosiveness ntawm caustic soda yaj nyob rau hauv dej.
