Cov lus qhia kev nyab xeeb
Thaum muaj xwm txheej ceev: cov pa hluav taws kub hnyiab, sib xyaw nrog huab cua tuaj yeem tsim cov khoom sib tov sib xyaw, thaum tshav kub lossis qhib nplaim tawg, cov pa roj yog sib dua li huab cua, siv hauv tsev thiab khaws cia, cov dej ntws tawm thiab nyob twj ywm ntawm lub ru tsev tsis yooj yim rau paug, nyob rau hauv cov ntaub ntawv ntawm Mars yuav ua rau tawg.
GHS Risk Pawg:Flammable gas 1, Pressurized gas - Compressed gas, self-reactive substance -D, tshwj xeeb lub hom phiaj organ system toxicity thawj tiv tauj -1, mob qhov muag loj / qhov muag khaus -2, mob toxicity - tib neeg nqus tau pa -1
Lus ceeb toom: Danger
Cov lus piav qhia txog kev phom sij: cov pa taws heev; Gas nyob rau hauv siab, yog rhuab tuaj yeem tawg; Cua sov tuaj yeem ua rau combustion - kev sib cuag thib ob thiab kev puas tsuaj ntawm lub cev; Ua rau qhov muag khaus heev; Ntxub neeg tuag.
Cov kev ceev faj:
· Kev ceev faj: - Khaws kom deb ntawm qhov hluav taws kub, qhov hluav taws kub thiab qhov chaw kub. Tsis haus luam yeeb. Siv cov cuab yeej nkaus xwb uas tsis tsim hluav taws xob - siv cov khoom siv hluav taws xob tawg, qhov cua thiab teeb pom kev zoo. Thaum lub sij hawm hloov cov txheej txheem, lub thawv yuav tsum tau muab tso rau hauv av thiab txuas kom tsis txhob muaj hluav taws xob zoo li qub,
- Khaws lub thawv kaw
- Siv cov cuab yeej tiv thaiv tus kheej raws li xav tau,
- Tiv thaiv cov pa tawm mus rau hauv chaw ua haujlwm huab cua thiab tsis txhob nqus cov pa tib neeg.
- Tsis txhob noj, haus lossis haus luam yeeb hauv chaw ua haujlwm.
- Txwv tsis pub tawm mus rau ib puag ncig,
· Cov xwm txheej teb
Thaum muaj hluav taws kub, dej pos huab, ua npuas ncauj, carbon dioxide thiab hmoov qhuav yog siv los tua hluav taws.
- Thaum nqus tau, sai sai tawm ntawm qhov chaw mus rau qhov chaw uas muaj huab cua ntshiab, ua kom txoj hauv kev tsis muaj kev cuam tshuam, yog tias ua tsis taus pa nyuaj, muab cov pa oxygen, ua pa, lub plawv nres, ua haujlwm tam sim cardiopulmonary resuscitation, kho mob.
· Kev ruaj ntseg cia:
- Khaws cov thawv ntim khoom kaw thiab khaws cia rau hauv qhov chaw txias, cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov thiab tsis txhob sib cuag nrog oxidants. Cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua tshuab tau txais yuav. Nruab nrog ntau yam thiab ntau ntawm cov khoom siv hluav taws xob thiab cov khoom siv kho mob thaum muaj xwm ceev.
· Kev pov tseg cov khoom pov tseg: - Kev pov tseg raws li lub teb chaws thiab hauv cheeb tsam cov cai, lossis tiv tauj nrog cov chaw tsim khoom los txiav txim siab txoj kev pov tseg Lub cev thiab tshuaj lom neeg muaj kev phom sij: flammable, tuaj yeem tsim cov khoom tawg thaum sib xyaw nrog huab cua, thaum muaj cua sov lossis qhib hluav taws tawg. yog sib dua li huab cua, nyob rau hauv tsev siv thiab cia, cov pa roj paug nce thiab nyob twj ywm ntawm lub ru tsev yog tsis yooj yim rau paug, nyob rau hauv cov ntaub ntawv ntawm Mars yuav ua rau tawg.
Kev phom sij rau kev noj qab haus huv:Ntawm lawv, phosphine Cheebtsam feem ntau ua rau lub paj hlwb, ua pa, plawv, raum thiab siab. 10mg / m raug rau 6 teev, cov tsos mob ntawm kev lom; Ntawm 409 ~ 846mg / m, kev tuag tshwm sim 30min rau 1h.
Mob me me lom lom, tus neeg mob muaj mob taub hau, qaug zog, xeev siab, insomnia, nqhis dej, qhuav qhov ntswg thiab caj pas, hauv siab nruj, hnoos thiab kub taub hau; Cov tshuaj lom nruab nrab, cov neeg mob me me ntawm kev nco qab, ua tsis taus pa, myocardial puas; Cov tshuaj lom neeg mob hnyav ua rau coma, convulsions, pulmonary edema thiab pom tseeb myocardial, daim siab thiab lub raum puas. Kev sib cuag ntawm daim tawv nqaij ncaj qha nrog kua tuaj yeem ua rau frostbite.
Environmental hazards:Nws tuaj yeem ua paug rau huab cua, nws tuaj yeem ua rau muaj kuab lom rau hauv dej.
