Cov Lus Cim Khoom
Muaj zog corrosiveness: Sodium hydroxide yog corrosive heev thiab tuaj yeem ua rau tawv nqaij, qhov muag thiab khaub ncaws. Nco ntsoov hnav tsom iav tiv thaiv thiab cov hnab looj tes acid- thiab alkali-resistant kom tsis txhob muaj kev sib cuag ncaj qha.
Dilution thiab cia: Thaum diluting, alkali yuav tsum tau nchuav rau hauv dej kom tsis txhob boiling thiab splashing. Khaws rau hauv qhov chaw qhuav thiab qhov cua, kom deb ntawm qhov hluav taws kub thiab qhov cua sov, tiv thaiv los ntawm ya raws thiab nag, thiab muab cais los ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob thiab cov kua qaub.
Kev tiv thaiv tus kheej: Hnav cov khaub ncaws uas tiv taus cov kua qaub thiab alkali, tiv thaiv tsom iav thiab cov hnab looj tes tiv thaiv acid thiab alkali thaum ua haujlwm. Hnav cov pa lossis oxygen respirator thaum tsim nyog. Kev haus luam yeeb, noj mov thiab haus cawv yog txwv tsis pub nyob hauv chaw ua haujlwm.
Kev kho mob xwm txheej ceev: Yog tias koj tuaj yeem ntsib nrog sodium hydroxide, yaug tam sim ntawd nrog dej kom ntau thiab siv cov tshuaj boric acid. Yog tias koj tsis xis nyob, nrhiav kev kho mob tam sim ntawd.
