Khaws cia rau hauv ib lub tsev rau khoom kom qhuav thiab muaj cua sov.
1. Thawv: Khw TMG hauv cov thawv ntim kaw kom tiv thaiv kom tsis txhob muaj kev sib kis thiab evaporation. Siv cov thawv ua los ntawm cov ntaub ntawv uas tau tshaj nrog cov hauv paus khov kho.
2. Kub: Khaws TMG hauv qhov chaw txias, qhuav qhov chaw kom deb ntawm kev tshav ntuj ncaj qha thiab kub. Chav sov feem ntau haum, tab sis yuav tsum cia qis dua 25 ° C (77 ° F) thaum ua tau.
3. Cov av noo: vim TMG yog hygroscopic (nws nqus ya raws los ntawm huab cua), nws yog ib qho tseem ceeb kom khaws nws hauv cov av noo ib puag ncig kom tiv thaiv nws los ntawm nqus ya raws.
4. Kev ceev faj kev nyab xeeb: Ua kom cov chaw muag khoom tau zoo thiab ua kom muaj kev ntsuas kev nyab xeeb zoo li TMG tej zaum yuav ua rau tawv nqaij thiab qhov muag.
5. Daim ntawv lo: daim ntawv lo qhia kom meej nrog lub npe tshuaj lom neeg, kev xav, thiab qee cov ntaub ntawv cuam tshuam kev phom sij.
Tetramethylguzidine (tmg) tuaj yeem ua rau muaj kev phom sij rau tib neeg lub cev yog tias tsis muaj kev ceeb toom kev nyab xeeb. Nov yog qee cov ntsiab lus tseem ceeb txog nws cov tshuaj lom thiab kev nyab xeeb:
1. Iritation: TMG tuaj yeem ua rau tawv nqaij, ob lub qhov muag, thiab ua pa ua pa. Sib cuag ncaj qha nrog kua yuav ua rau cov tshuaj hlawv lossis khaus.
2. Inhalation: nqus tau ntawm TMG vapor yuav ua rau muaj kev cuam tshuam ua pa thiab lwm yam kev tsis zoo.
3. Kev noj: Kev noj ntshav ntawm TMG tej zaum yuav raug mob thiab yuav ua rau muaj kev cuam tshuam pa taws lossis lwm yam cuam tshuam.
4. Kev ceev faj kev nyab xeeb: Thaum tuav TMG, ib txwm siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) xws li hnab looj tes, khawm, thiab lub tsho ntev. Ua haujlwm hauv qhov chaw muaj cua zoo lossis siv cov lus ua suab paj nruag kom txo qis kev raug.
5. Thawj pab: Yog tias raug tshuaj, coj mus ua ntej kev ntsuas kev pab tsim nyog, xws li yaug qhov chaw cuam tshuam nrog dej thiab nrhiav kev kho mob yog tias tsim nyog.
Thaum thauj tetramethylguzidine (tmg), qee qhov kev ceev faj yuav tsum tau ua kom muaj kev nyab xeeb thiab ua raws li cov cai. Nov yog qee qhov kev txiav txim siab tseem ceeb los coj mus rau hauv tus account:
1. Kev tswj hwm ua raws: Tshawb xyuas thiab ua raws li cov kev tswj hwm hauv zos, thiab thoob ntiaj teb hais txog kev thauj mus los ntawm cov khoom phom sij. Tus TMG tej zaum yuav raug cais raws li cov khoom tsim kev puas tsuaj, yog li txhua yam ntaub ntawv thauj khoom muaj tseeb thiab ua tiav.
2. Ntim: Siv cov ntaub ntawv ntim uas tsim nyog uas tau sib xws nrog TMG. Cov ntim khoom yuav tsum yog cov khoom lag luam thiab ua cov khoom siv uas tuaj yeem tiv taus cov yam ntxwv ntawm cov tshuaj. Siv cov ntsaws ruaj ruaj los tiv thaiv kom togage thaum kev thauj mus los.
3. Sau npe: Sau npe kom meej meej daim ntawv nrog lub npe tshuaj lom neeg, cim kev phom sij, thiab cov ntaub ntawv muaj kev phom sij. Qhov no suav nrog cov lus qhia daws teeb meem thiab cov ntaub ntawv tiv toj thaum muaj xwm ceev.
4. Kev tswj kub: xyuas kom meej tias kev xa khoom kom muaj qhov kub ruaj khov, li huab cua sov ruaj khov tuaj yeem cuam tshuam qhov ruaj khov ntawm TMG.
5. Zam kev yaa dej: txij li TMG yog Hygroscopic, thov xyuas kom cov ntim yog noo noo-pov thawj kom tiv thaiv kev nqus dej thaum thauj mus los.
6. Hom kev thauj: Xaiv hom tsim nyog ntawm thauj (av, huab cua, hiav txwv) uas ua raws li cov kev cai txaus ntshai. Nco ntsoov tias lub tsheb thauj tau nruab nrog cov khoom tsim nyog los ua kom muaj kev phom sij.
7. Cov txheej txheem thaum muaj xwm ceev: Muab cov ntaub ntawv ntawm cov txheej txheem thaum muaj xwm txheej ceev thaum muaj dej ntws los yog xau thaum thauj khoom. Ua kom ntseeg tau cov neeg ua haujlwm pabcuam hauv kev thauj yog kev cob qhia los daws cov khoom siv txaus ntshai.
8. Cov ntaub ntawv: Qhov no suav nrog txhua daim ntawv thauj khoom uas tsim nyog xws li Bill of Lading, SDS cov ntaub ntawv nyab xeeb (SDS) thiab cov ntawv tshaj tawm.
