Cov lus qhia kev nyab xeeb
Thaum muaj xwm txheej ceev: Tsis muaj roj, lub tog raj kheej lub thawv yog yooj yim rau overpressure nyob rau hauv tshav kub, muaj kev pheej hmoo ntawm tawg. Cryogenic kua tuaj yeem ua rau frostbite.
Gas to, ntau inhalation yog yooj yim rau asphyxiate.
GHS Hazard Class: Raws li Kev Tshawb Fawb Tshuaj, Cov Ntawv Ceeb Toom thiab Cov Lus Ceeb Toom Qhia Tshwj Xeeb series, cov khoom lag luam yog cov roj hauv siab - cov roj liquefied.
Lus ceeb toom: ceeb toom
Cov ntaub ntawv txaus ntshai: Gas nyob rau hauv siab, yog tias raug tshav kub tuaj yeem tawg.
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.
Cov lus teb raug xwm txheej: txiav tawm qhov xau, 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. Kev pov tseg pov tseg: Cov khoom no lossis nws lub thawv yuav tsum muab pov tseg raws li cov cai hauv zos. Lub cev thiab tshuaj lom neeg muaj kev phom sij: nws tsis hlawv roj, thiab lub tog raj kheej lub thawv yog yooj yim rau overpressure thaum rhuab, thiab muaj kev pheej hmoo ntawm tawg. Cryogenic kua tuaj yeem ua rau frostbite. High concentration inhalation yuav ua rau suffocation.
Kev phom sij rau kev noj qab haus huv: Kev nqus tau ntev ntev tuaj yeem ua rau coma, ploj ntawm kev rov qab los, dilation lossis contraction ntawm cov menyuam kawm ntawv, incontinence, ntuav, ua pa nres, poob siab thiab tuag. Frostbite tuaj yeem tshwm sim thaum daim tawv nqaij lossis qhov muag raug rau cov dej khov qhuav lossis kua carbon dioxide.
Kev phom sij ib puag ncig: Cov pa roj carbon dioxide ntau ntau rau cov cua tuaj yeem rhuav tshem lub ntiaj teb ozone txheej, me me ntawm carbon dioxide emissions tuaj yeem tawm ncaj qha.
