Qhuav thiab khaws cia ntawm chav tsev kub
1. Thawv: Siv airtight ntim ua los ntawm cov khoom siv tau tshaj, xws li iav lossis qee yam plastics. Nco ntsoov tias cov thawv tau sau kom pom tseeb.
2. Chaw cia khoom: khw Perc nyob rau hauv qhov chaw txias, muaj kev pom zoo ntawm lub hnub ncaj qha los ntawm tshav ntuj ncaj qha, cua sov thiab qhib cov nplaim taws. Nws yuav tsum tau muab cia rau hauv cov khoom siv hluav taws xob tsim khoom.
3. Qhov kub thiab txias: khaws cia kub nyob hauv cov kev pom zoo, feem ntau ntawm 15 ° C (59 ° F thiab 86 ° F).
4. Tsis meej: Thov khaws cia kom deb ntawm cov muaj zog oxidants, acids thiab cov hauv paus, thiab cov hlau ua kom tiv thaiv kev phom sij.
5.
6. Cov cuab yeej tiv thaiv tus kheej (PPE): Thaum tuav lossis hloov hnab looj tes, suav nrog hnab looj tes tsim nyog, suav nrog hnab looj tes thiab hnab looj tes, kom txo qis kev raug.
7. Kev tswj hwm ua raws li: Ua raws cov cai hauv nroog thiab cov lus qhia rau kev khaws cov khoom siv phom sij, suav nrog cov kev cai tshwj xeeb rau perchlorethylene.

Yog lawm, Tetrachlorethylene yog kev puas tsuaj rau tib neeg. Nov yog qee cov ntsiab lus tseem ceeb txog nws cov teebmeem kev noj qab haus huv:
1. Inhalation ntawm tetrachlorethylene vapors tuaj yeem ua rau muaj teeb meem ua pa, kiv taub hau, mob siab, yuav ua rau muaj kev kub siab nruab nrab.
2. Cov tawv nqaij thiab qhov muag tsis voos: Saib xyuas ncaj qha nrog tetrachlorethylene tuaj yeem ua rau tawv nqaij voos thiab yuav ua rau muaj kev txob ntswg lossis puas tsuaj.
3. Kev ua kom ntev ntev los yog ua rau tib neeg mob siab rau cov kev tshawb fawb txog kabmob (ooc).
4. Ib puag ncig cov teeb meem: Tetrachlorethylene tuaj yeem ua paug pa, dej, thiab av, coj mus rau cov teeb meem kev noj qab haus huv ib puag ncig kev noj qab haus huv.
