Cov lus qhia kev nyab xeeb
Thaum muaj xwm txheej ceev: Oxidizing gas, combustion pab. Lub cylinder thawv yog nquag overpressure thaum rhuab, thiab muaj kev pheej hmoo ntawm tawg. Cryogenic kua yog yooj yim conductive.
Ua rau frostbite.
GHS Hazard Class: Raws li Kev Ntsuas Tshuaj, Daim Ntawv Ceeb Toom thiab Ceeb Toom Specification series cov qauv, cov khoom yog oxidizing gas Class 1; Gas nyob rau hauv siab compressed gas.
Lus ceeb toom: Danger
Cov ntaub ntawv pov thawj: tej zaum yuav ua rau lossis ua rau muaj kev kub ntxhov ntau dua; Oxidizing tus neeg sawv cev; Gases nyob rau hauv siab uas tuaj yeem tawg yog tias cua sov:
Cov kev ceev faj:
Kev ceev faj: Khaws kom deb ntawm qhov chaw kub, qhib nplaim taws, thiab qhov chaw kub. Tsis haus luam yeeb hauv chaw ua haujlwm. Txuas nrog li qub, kav dej, twj paj nruag, thiab lwm yam, yog nruj me ntsis txwv tsis pub roj. Tsis txhob siv cov cuab yeej uas yuav ua rau lub txim taws. Siv cov kev ntsuas los tiv thaiv hluav taws xob zoo li qub. Cov thawv ntim hauv av thiab cov khoom siv txuas nrog. Cov lus teb raug xwm txheej: txiav tawm qhov xau, tshem tawm tag nrho cov phom sij hluav taws, tsim nyog qhov cua, ua kom nrawm nrawm.
Kev ruaj ntseg cia: Tsis txhob tshav ntuj thiab cia rau hauv qhov chaw muaj cua zoo. Khaws nyob rau hauv kev sib cais los ntawm kev txo cov neeg ua hauj lwm thiab cov nplaim taws/combustibles.
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: cov pa roj muaj combustion-txhawb thiab oxidizing zog. Compressed roj, lub tog raj kheej thawv yog yooj yim rau overpressure thaum rhuab, muaj kev pheej hmoo ntawm tawg. Yog hais tias lub qhov ncauj ntawm lub raj mis oxygen yog stained nrog roj, thaum cov pa tawm sai sai, cov roj sai sai oxidizes, thiab cov cua sov tsim los ntawm kev sib txhuam ntawm cov cua kub siab thiab lub qhov ncauj ntawm lub raj mis ntxiv ua rau cov tshuaj tiv thaiv oxidation, cov roj paug ntawm lub raj mis oxygen los yog lub siab txo valve yuav ua rau combustion los yog tawg, kua oxygen yog lub teeb xiav kua, thiab muaj zog paramagnetism. Cov pa oxygen ua kua ua rau cov khoom nws kov heev. Cov pa oxygen kuj tseem muaj zog oxidizing tus neeg sawv cev: cov organic teeb meem kub hnyiab hauv cov kua. Qee yam khoom tuaj yeem tawg yog tias muab tso rau hauv cov pa oxygen rau lub sijhawm ntev, suav nrog asphalt. Kev phom sij rau kev noj qab haus huv: Thaum lub siab ib txwm muaj, cov tshuaj lom pa oxygen tuaj yeem tshwm sim thaum cov pa oxygen ntau dua 40%. Thaum nqus tau 40% mus rau 60% oxygen, muaj qhov tsis xis nyob retrosternal, hnoos qeev, thiab tom qab ntawd hauv siab nruj, retrosternal kub hnyiab, thiab hnoos hawb pob: pulmonary edema thiab asphyxia tuaj yeem tshwm sim rau qhov mob hnyav. Thaum cov pa oxygen concentration siab dua 80%, cov leeg ntawm lub ntsej muag twitch, daj ntseg ntsej muag, kiv taub hau, tachycardia, vau, thiab tom qab ntawd tag nrho lub cev tonic convulsions, coma, ua pa tsis ua haujlwm thiab tuag. Kev sib cuag ntawm daim tawv nqaij nrog cov pa oxygen tuaj yeem ua rau mob hnyav heev.
Environmental hazard: harmless rau ib puag ncig.
