5. Kev nyab xeeb ceev faj:Khaws nws kom deb ntawm cov tshuaj uas tsis sib xws (xws li cov neeg sawv cev oxidizing muaj zog heev) thiab paub tseeb tias kom nws ncav cuag cov menyuam yaus thiab tsiaj.
Cov lus qhia dav dav
Sab laj tus kws kho mob. Muab cov ntaub ntawv kev nyab xeeb rau tus kws kho mob.
Ua pa
Yog nqus tau, txav tus neeg mob mus rau cua tshiab. Yog tias ua tsis taus pa nres, muab ua pa ua pa. Sab laj tus kws kho mob.
Daim tawv nqaij tiv tauj
Yaug nrog xab npum thiab dej kom ntau. Sab laj tus kws kho mob.
qhov muag hu
Yaug kom huv nrog cov dej kom ntau li 15 feeb thiab sab laj kws kho mob.
Kev noj
Tsis txhob muab dab tsi los ntawm qhov ncauj rau tus neeg tsis nco qab lawm. Yaug koj lub qhov ncauj nrog dej. Sab laj tus kws kho mob.
Tetrabutylammonium bromide (TBab) feem ntau suav tias muaj tsawg toxicity, tab sis nws tseem yuav ua rau qee qhov kev phom sij. Ntawm no yog qee cov ntsiab lus tseem ceeb txog nws kev nyab xeeb:
1. Kev txob khoom: TBAB tuaj yeem ua rau tawv nqaij, qhov muag thiab ua pa. Zam kev sib cuag ncaj qha nrog tawv nqaij lossis qhov muag thiab hnav cov cuab yeej tiv thaiv tus kheej (PPE) xws li hnab looj tes thiab gobgles thaum tuav.
2. Inhalation: nqus tau plua plav ntawm cov hmoov av Nws raug nquahu kom ua haujlwm hauv qhov chaw muaj pa tau zoo lossis siv kev tiv thaiv ua pa kom haum thaum tsim nyog.
3. Ib qho kev cuam tshuam ib puag ncig: zoo li ntau yam tshuaj lom neeg, TBAB yuav cuam tshuam rau ib puag ncig yog tias tau tso tawm rau hauv dej lub cev. Nws yog ib qho tseem ceeb kom ua raws li cov lus qhia raug pov tseg kom txo qis kev cuam tshuam ib puag ncig.
4. Handling ceev faj: Nco ntsoov saib rau TBAB cov ntaub ntawv kev nyab xeeb cov ntaub ntawv (sds) rau cov lus qhia kev nyab xeeb, kev ntsuas kev nyab xeeb, ntsuas kev ntsuas kev nyab xeeb.
Hauv kev xaus, txawm hais tias tus TBab tsis raug cais raws li cov tshuaj phem uas muaj kev phom sij, nws yuav tsum tau ua raws li kev saib xyuas thiab kev nyab xeeb yuav tsum tau ua raws li txo qee qhov phom sij txaus ntshai.
1. Ntim:
Siv cov thawv uas tsim nyog thiab muab khi lawv kom nruj kom tiv thaiv kom tsis txhob to feakage thiab noo noo nqus.
Ua kom cov ntim ntim tau sib haum nrog lub tbab thiab tuaj yeem tiv thaiv cov khoom xa tuaj.
2. Tag:
Daim ntawv sau kom meej meej nrog cov npe tshuaj, cov ntaub ntawv phom sij thiab cov lus qhia daws teeb meem cuam tshuam.
Suav nrog cov cim kev phom sij yog tias yuav tsum muaj.
3.Temperatature tswj:
TBAB yuav tsum tau muab cia rau hauv qhov chaw txias thiab qhuav thaum thauj mus los kom tiv thaiv kev tsis zoo lossis kev tawm tsam.
Zam kev ua kom sov siab.
4. Zam kev tsis sib haum xeeb:
Nco ntsoov tias TBAB tsis thauj ua ke nrog cov khoom siv tsis sib xws (xws li cov neeg sawv cev lossis cov acids muaj zog) los tiv thaiv qee qhov kev tshwm sim.
5. Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE):
Cov neeg ua haujlwm koom nrog hauv kev thauj mus los yuav tsum tau hnav cov khoom looj tes tsim nyog ntawm tus kheej, suav nrog hnab looj tes, hnab looj tes, thiab qhov ncauj qhov ntswg, txo qis kev raug.
6. Tus Txheej Txheem Ceev:
Muaj cov txheej txheem xwm ceev nyob rau hauv qhov chaw ntawm nchuav lossis raug nplua thaum thauj khoom. Qhov no suav nrog kev muaj cov khoom siv spill thiab cov khoom siv ua ntej npaj.
7. Kev tswj hwm ua raws li:
Ua raws li txhua lub zos, cov kev cai teb chaws thiab thoob ntiaj teb hais txog kev thauj cov tshuaj lom neeg, nrog rau cov khoom tshwj xeeb rau cov khoom lag luam txaus ntshai.
