1. Kev ceev faj rau kev tuav nyab xeeb
Kev tiv thaiv kev tiv thaiv
Kov cov chaw muaj cua zoo. Tshem tawm txhua qhov chaw ntawm ignition, thiab tsis tsim cov nplaim taws lossis cov txim taws. Ua kev tawm tsam kev tawm tsam tawm tsam cov kab mob ib txwm muaj.
Cov lus qhia ntawm kev nyiam huv
Tsis txhob noj, haus thiab haus luam yeeb hauv cov chaw ua haujlwm. Ntxuav tes tom qab siv. Tshem cov khaub ncaws hnav thiab cov cuab yeej tiv thaiv ua ntej nkag mus noj thaj chaw.
2. Cov xwm txheej rau kev nyab xeeb, suav nrog kev ua tsis tiav
Txav deb ntawm tshav kub, txim taws, thiab nplaim taws. Cia kom deb ntawm cov khoom siv ntawm ignition. Khaws rau hauv lub thawv kaw ntom nti. Khaws rau hauv qhov chaw txias, qhuav, muaj cua zoo-muaj qhov chaw nyob deb ntawm cov tshuaj tsis sib xws.
1. Ashity:
Cov tshuaj yog ruaj khov nyob rau hauv ib txwm khaws cia thiab tuav cov xwm txheej.
2. Tshuaj Muaj Zog:
Ruaj khov nyob rau hauv ib txwm kub thiab kev ntsuas.
3. Muaj peev xwm muaj kev phom sij:
Nyob rau hauv ib txwm mob, tsis muaj kev phom sij yuav tshwm sim.
4. Cov xwm txheej zam kom tsis txhob:
Cov ntaub ntawv tsis sib xws, hluav taws xob, cov muaj zog oxidants.
5. Cov ntaub ntawv tsis sib xws:
Oxidizing cov neeg sawv cev.
6. Kev phom sij cov khoom siv dag zog:
Cov pa roj carbon monoxide, khaus thiab muaj kuab lom thiab roj av, carbon dioxide.
1. Kev tswj hwm ua raws: Tshawb xyuas thiab ua raws li cov kev cai hauv zos, thiab thoob ntiaj teb hais txog kev thauj khoom. Kev txiav txim siab lim horthoformate yuav raug faib ua cov khoom siv phom sij, yog li nco ntsoov ua raws li cov lus qhia tsim nyog (piv txwv, lub npe tsim nyog).
2. Ntim: Siv cov ntaub ntawv ntim uas tsim nyog uas tsim nyog nrog chimethyl orthoformate. Lub thawv yuav tsum tau ua cov ntaub ntawv uas tuaj yeem tiv thaiv cov tshuaj thiab yuav tsum tau muab kaw kom muaj kev tiv thaiv kom tiv thaiv kom tsis txhob to.
3. Sau npe: Sau npe kom meej meej daim ntawv nrog lub npe tshuaj lom neeg, cov cim kev phom sij thiab muaj cov lus qhia daws teeb meem cuam tshuam. Ua kom meej meej tag nrho cov ntawv sau ua kom raug thiab tau raws li kev cai tswj hwm.
4. Kev tswj kub: Yog tias tsim nyog, xyuas kom meej cov kev xa khoom kom muaj qhov kub ruaj khov kom tiv thaiv kev cuam tshuam lossis tsis muaj kev cuam tshuam.
5. Cov ntaub ntawv: suav nrog txhua cov ntaub ntawv thauj khoom uas xav tau xws li cov ntaub ntawv nyab xeeb (SDS), shipping manifest, thiab lwm yam ntaub ntawv muaj feem cuam tshuam.

8. Zam cov ntaub ntawv tsis sib xws: Xyuas kom cov chimethyl esters tsis tau thauj ua ke nrog cov ntaub ntawv tsis sib xws (xws li oxidants muaj zog lossis acids) los tiv thaiv kev phom sij.
Yog lawm, txiav Orheamormy yog txiav txim siab txaus ntshai. Nov yog qee cov ntsiab lus tseem ceeb txog nws cov kev phom sij:
1. Flammability: txiav luam yeeb yog cov nplaim taws thiab yuav ua rau hluav taws kub txaus ntshai yog tias muaj cua sov, txim taws lossis qhib cov nplaim taws.
2. Kev Noj Qab Haus Huv Daws: Tej zaum yuav tsim kev puas tsuaj yog tias nqus tau, ingested lossis nqus los ntawm daim tawv nqaij. Kev sib chwv yuav ua rau lub qhov muag, tawv nqaij thiab ua pa ua pa. Kev ntev lossis rov kis tau zoo dua tuaj yeem ua rau muaj kev puas tsuaj loj dua.
3. Ib puag ncig kev phom sij: yog tias tsis txaus ntseeg, nws yuav ua rau muaj kev pheej hmoo rau ib puag ncig, yog li tshem tau thiab pov tseg yog qhov tseem ceeb heev.
4. Kev tswj hwm kev faib tawm: nyob ntawm cov kev cai thiab cov kev cai tshwj xeeb hauv koj thaj chaw uas xav tau kev kov yeej, chaw cia khoom, thiab kev ntsuas tsheb thauj khoom.
