Thaum thauj N-methyl-n ', n'-diphenylenea, nws yog ib qho tseem ceeb kom ua raws cov lus qhia kom muaj kev nyab xeeb thiab ua raws li kev cai. Nov yog qee qhov kev txiav txim siab tseem ceeb rau kev thauj cov tshuaj no:
1.Kev tswj hwm ua raws: kom cov khoom xa tuaj ua raws li cov kev tswj hwm hauv zej zog, thiab thoob ntiaj teb cov cai hais txog cov khoom tsim kev puas tsuaj. Qhov no suav nrog cov kev cai los ntawm cov koom haum xws li Asmeskas Lub Tuam Tsev Txhawb Kev Thauj Mus Los (DOT) lossis European Chemical Lub Chaw Haujlwm (chacha).
2.Ntim: Siv cov ntaub ntawv ntim uas tsim nyog uas tau sib xws nrog n-methyl-n ', n'-diphenylurea. Lub khob ntim yuav tsum yog khov kho, sau npe thiab sau npe kom meej. Siv cov ntsaws ruaj ruaj los tiv thaiv kom tsis txhob muaj roj thaum thauj mus los.
3.Daim Ntawv Sau Npe: Sau npe kom meej rau lub hnab ntim tshuaj, lub npe, cov cim kev phom sij, thiab cov ntaub ntawv kev nyab xeeb. Qhov no suav nrog cov lus qhia daws teeb meem thiab cov ntaub ntawv tiv toj thaum muaj xwm ceev.
4. Cov kev thauj mus los: Zam kev thauj mus los ntau, noo noo, thiab kev puas tsuaj ntawm lub cev thaum thauj cov tshuaj. Zam kev tshav ntuj ncaj qha thiab khaws cia rau hauv qhov chaw muaj cua zoo.
5. Cov Ntaub Ntawv: Npaj thiab nqa tag nrho cov ntaub ntawv tsim nyog, suav nrog cov ntaub ntawv ntaub ntawv tsim nyog, nrog rau cov ntaub ntawv kev nyab xeeb (SDS), cov ntaub ntawv xa khoom, thiab cov ntawv tshaj tawm.
6.Kev Kawm: Xyuas kom cov neeg ua haujlwm tau koom nrog kev phom sij rau n-methyl-n ', n'-diphenylenya.
7.Cov Txheej Txheem Ceev: Muaj cov txheej txheem thaum muaj xwm ceev hauv qhov chaw nchuav lossis tsoo thaum thauj khoom. Qhov no suav nrog kev muaj cov khoom siv tshuaj dawb thiab cov khoom tiv thaiv tus kheej (PPE) npaj txhij.
8.Hom kev thauj: Xaiv cov qauv tsim nyog ntawm thauj (kev, huab cua, huab cua lossis hiav txwv) raws li kev deb, kev cai maj.
