Cov lus qhia kev nyab xeeb
Txheej txheem cej luam xwm ceev: Cov pa roj ntau heev. Nyob rau hauv cov ntaub ntawv ntawm huab cua tuaj yeem tsim cov khoom sib tov sib xyaw, thaum qhib hluav taws, muaj kev kub ntxhov kub kub kub heev.
GHS Hazard Class: Raws li kev faib tshuaj lom neeg, Daim Ntawv Ceeb Toom thiab Kev Ceeb Toom Cov Qauv Txheej Txheem series, cov khoom lag luam yog cov roj hluav taws xob: Chav Kawm 1; Gas nyob rau hauv siab: compressed gas.
Lus ceeb toom: Danger
Cov ntaub ntawv pov thawj: flammable heev. Cov pa hluav taws kub heev, muaj cov roj cua siab, tuaj yeem tawg thaum tshav kub.
Cov lus qhia ua ntej
Kev tiv thaiv kev tiv thaiv: Khaws kom deb ntawm qhov chaw tshav kub, qhov hluav taws xob, qhib nplaim taws, qhov chaw kub, thiab tsis txhob haus luam yeeb hauv chaw ua haujlwm. Hnav cov khaub ncaws hluav taws xob tiv thaiv zoo li qub thiab siv cov cuab yeej hluav taws kub tsis zoo thaum siv.
Cov lus teb raug xwm txheej: Yog tias cov pa xau hluav taws kub hnyiab, tsis txhob tua hluav taws tshwj tsis yog tias lub qhov hluav taws xob tuaj yeem raug txiav tawm kom nyab xeeb. Yog tias tsis muaj kev phom sij, tshem tawm tag nrho cov khoom siv hluav taws xob.
Kev ruaj ntseg cia: Tsis txhob tshav ntuj thiab cia rau hauv qhov chaw muaj cua zoo. Tsis txhob cia nrog oxygen, compressed cua, halogens (fluorine, chlorine, bromine), oxidants, thiab lwm yam
Kev pov tseg: Cov khoom no lossis nws lub thawv yuav tsum muab pov tseg raws li cov cai hauv zos.
Kev pheej hmoo ntawm lub cev thiab tshuaj lom neeg tseem ceeb: sib zog dua huab cua, qhov siab siab tuaj yeem ua rau ua pa ventricular yooj yim. Cov pa roj compressed, tsis tshua muaj hluav taws kub, roj tsis huv yuav tawg thaum ignited. Lub cylinder thawv yog nquag overpressure thaum rhuab, thiab muaj kev pheej hmoo ntawm tawg. Cov kaus mom kev nyab xeeb thiab cov khoom siv roj hmab poob siab yuav tsum muab ntxiv rau hauv lub tog raj kheej thaum lub sijhawm thauj mus los.
Kev phom sij rau kev noj qab haus huv: Kev sib sib zog nqus tuaj yeem ua rau hypoxia thiab asphyxia.
