Cov lus qhia kev nyab xeeb
Cov ntsiab lus thaum muaj xwm txheej ceev: Tsis muaj roj, lub tog raj kheej lub thawv yog yooj yim rau overpressure thaum rhuab, muaj kev pheej hmoo ntawm tawg. Frostbite yog yooj yim tshwm sim los ntawm kev sib cuag ncaj qha nrog kua ammonia. GHS tej pawg muaj kev phom sij: Raws li kev faib tshuaj lom neeg, daim ntawv ceeb toom thiab Ceeb toom cov qauv qauv; Cov khoom yog compressed gas nyob rau hauv siab.
Lus ceeb toom: ceeb toom
Cov ntaub ntawv txaus ntshai: Gas nyob rau hauv siab, yog tias cua sov 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: 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: tsis muaj roj, lub tog raj kheej lub thawv yog yooj yim rau overpressure thaum rhuab, thiab muaj kev pheej hmoo ntawm tawg. High concentration inhalation yuav ua rau suffocation.
Kev raug rau cov kua ammonia tuaj yeem ua rau frostbite.
Kev phom sij rau kev noj qab haus huv: cov ntsiab lus nitrogen hauv huab cua siab dhau, yog li cov pa oxygen ib feem ntawm cov pa nqus tau poob, ua rau tsis muaj asphyxia. Thaum cov concentration ntawm nitrogen tsis siab dhau lawm, tus neeg mob pib hnov lub hauv siab nruj, ua tsis taus pa, thiab tsis muaj zog. Tom qab ntawd muaj kev ntxhov siab, kev zoo siab heev, khiav, qw, trance, gait instability, hu ua "nitrogen moet tincture", tuaj yeem nkag mus rau hauv lub coma lossis coma. Nyob rau hauv siab concentration, cov neeg mob tuaj yeem ua tsis nco qab sai thiab tuag los ntawm kev ua pa thiab mob plawv.
Environmental harms: Tsis muaj kev puas tsuaj rau ib puag ncig.
