Cov lus qhia kev nyab xeeb
Cov ntsiab lus thaum muaj xwm txheej ceev: Tsis muaj xim, pungent tsw roj. Tsawg concentration ntawm ammonia tuaj yeem ua rau cov mucosa, siab concentration tuaj yeem ua rau cov ntaub so ntswg lysis thiab necrosis.
Mob hnyav: mob me me ntawm kua muag, mob caj pas, hnov qab, hnoos, phlegm thiab lwm yam; Congestion thiab edema nyob rau hauv conjunctival, qhov ntswg mucosa thiab pharynx; Kev tshawb pom hauv lub hauv siab X-ray yog zoo ib yam nrog bronchitis lossis peribronchitis.
Cov tshuaj lom nruab nrab ua rau cov tsos mob saum toj no ua rau mob plab thiab cyanosis: kev tshawb pom hauv siab X-ray zoo ib yam nrog mob ntsws lossis mob ntsws interstitial. Nyob rau hauv cov xwm txheej hnyav, cov tshuaj lom pulmonary edema tuaj yeem tshwm sim, lossis muaj mob ua pa nyuaj, cov neeg mob hnoos hnyav, ntau cov hnoos qeev liab, ua pa nyuaj, delirium, coma, poob siab thiab lwm yam. Laryngeal edema lossis bronchial mucosa necrosis, exfoliation thiab asphyxia tuaj yeem tshwm sim. High concentrations ntawm ammonia tuaj yeem ua rau reflex ua pa nres. Kua ammonia lossis siab concentration ammonia tuaj yeem ua rau qhov muag hlawv; Cov kua ammonia tuaj yeem ua rau tawv nqaij kub hnyiab. Flammable, nws cov vapor tov nrog huab cua tuaj yeem tsim cov khoom tawg.
GHS Hazard Class: Raws li Kev Ntsuas Tshuaj, Cov Ntawv Ceeb Toom thiab Cov Lus Ceeb Toom Cov Qauv Txheej Txheem, cov khoom raug cais raws li cov pa roj carbon monoxide-2: cov pa roj siab - roj liquefied; Daim tawv nqaij corrosion / khaus-1b; Qhov muag mob hnyav / qhov muag khaus-1; Kev phom sij rau dej ib puag ncig - mob 1, mob toxicity - inhalation -3.
Lus ceeb toom: Danger
Cov ntaub ntawv pov thawj: cov pa roj tsw qab; Gas nyob rau hauv siab, yog rhuab tuaj yeem tawg; Kev tuag los ntawm nqos; Ua rau mob hnyav ntawm daim tawv nqaij thiab qhov muag puas; Ua rau qhov muag loj heev; Muaj tshuaj lom rau cov kab mob hauv dej; Toxic los ntawm inhalation;
Cov kev ceev faj:
Kev tiv thaiv:
- Cia kom deb ntawm cov nplaim taws, qhov chaw kub, qhov hluav taws xob, qhov hluav taws kub, qhov chaw kub. Txwv tsis pub siv cov cuab yeej uas tuaj yeem ua kom tawg tau yooj yim; - Ceev faj tiv thaiv kom tsis txhob muaj hluav taws xob zoo li qub, hauv av thiab kev sib txuas ntawm cov ntim khoom thiab txais cov khoom siv;
- Siv cov khoom siv hluav taws xob tawg, qhov cua, teeb pom kev zoo thiab lwm yam khoom siv;
- Khaws lub thawv kaw; Tsuas yog ua haujlwm sab nraum zoov lossis hauv qhov chaw muaj cua zoo;
- Tsis txhob noj, haus lossis haus luam yeeb hauv chaw ua haujlwm;
- Hnav cov hnab looj tes tiv thaiv thiab tsom iav.
Cov lus teb raug xwm txheej: txiav tawm qhov xau kom ntau li ntau tau, tsim nyog qhov cua, ua kom nrawm nrawm. Nyob rau hauv cov cheeb tsam uas muaj kuab paug siab, tshuaj tsuag dej nrog hydrochloric acid thiab pos huab. Yog tias ua tau, cov pa roj seem lossis cov pa xau raug xa mus rau lub tshuab ntxhua khaub ncaws lossis txuas nrog lub tshuab ua pa nrog lub tshuab nqus tsev.
Kev ruaj ntseg cia: sab hauv tsev yuav tsum muab tso rau hauv qhov chaw txias thiab qhov cua; Cais cia nrog cov tshuaj, sub-acid bleach thiab lwm yam acids, halogens, kub, nyiaj, calcium, mercury, 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 phom sij rau lub cev thiab tshuaj lom neeg: cov pa taws ua pa; Sib tov nrog huab cua los ua ib qho kev sib xyaw tawg; Nyob rau hauv cov ntaub ntawv ntawm qhib hluav taws, lub siab kub zog yuav ua rau combustion tawg; Kev sib cuag nrog cov tshuaj fluorine, chlorine thiab lwm yam tshuaj lom neeg yuav tshwm sim.
Kev phom sij rau kev noj qab haus huv: ammonia rau hauv tib neeg lub cev yuav cuam tshuam lub voj voog tricarboxylic acid, txo lub luag haujlwm ntawm cytochrome oxidase; Ua rau lub hlwb muaj zog ammonia, tuaj yeem tsim cov teebmeem neurotoxic. High concentration ntawm ammonia tuaj yeem ua rau cov ntaub so ntswg lysis thiab necrosis.
Kev phom sij ib puag ncig: kev phom sij loj rau ib puag ncig, yuav tsum tau saib xyuas tshwj xeeb rau cov pa phem ntawm cov dej saum npoo av, av, huab cua thiab dej haus.
Kev phom sij tawg: ammonia yog oxidized los ntawm huab cua thiab lwm yam oxidizing neeg ua hauj lwm los tsim nitrogen oxide, nitric acid, thiab lwm yam, thiab acid los yog halogen drastic cov tshuaj tiv thaiv thiab tawg txaus ntshai. Kev sib cuag tsis tu ncua nrog qhov hluav taws kub kub thiab tuaj yeem tawg.
