Kev taw qhia txog kev siv cov tshuaj tua kab mob lom hauv kev ua haujlwm hauv av
Kev taw qhia txog yuav ua li cas khiav cov pa roj carbon monoxide hauv av: Lub luag haujlwm tseem ceeb rau cov neeg ua haujlwm hauv av yog anoxic asphyxiation, hydrogen sulfide lom thiab combustible gas explosions. Feem ntau tshwm sim yog hydrogen sulfide lom. Lub tshuab hluav taws xob sib xyaw tuaj yeem tshawb xyuas qhov concentration ntawm cov pa phem thiab cov pa phem hauv lub qhov dej tam sim ntawd thiab tau txais lub tswb.
1. Asphyxiation los ntawm carbon dioxide thiab roj. Ntxiv nrog rau kev ua pa ua pa thiab oxygen resuscitation rau cov neeg raug mob los ntawm carbon dioxide thiab gas suffocation, lawv cov tawv nqaij yuav tsum tau txhuam los yog ua kom hnov tsw ammonia los txhawb kev rov ua pa. lom los ntawm carbon monoxide.
2. Hydrogen sulfide lom. Nyob rau hauv cov ntaub ntawv ntawm hydrogen sulfide lom, ntxiv rau kev ua pa ua pa los yog resuscitating oxygen, koj muaj peev xwm muab paj rwb pob, phuam phuam, thiab lwm yam. soaked nyob rau hauv cov tshuaj chlorine rau hauv lub qhov ncauj. Chlorine yog ib qho tshuaj zoo ntawm hydrogen sulfide.
3. sulfur dioxide lom. Txij li thaum sulfur dioxide reacts nrog dej los tsim sulfuric acid, nws muaj zog stimulating nyhuv ntawm lub pa system thiab tej zaum yuav ua rau kub hnyiab nyob rau hauv mob hnyav. Yog li ntawd, ntxiv rau kev ua pa ua pa lossis cov pa oxygen resuscitator, cov tshuaj lom neeg raug mob yuav tsum tau muab mis nyuj, zib ntab los yog gargled nrog dej qab zib daws qhov mob. Txhawb nqa.
4. Dioxide huab cua lom lom. Cov tsos mob tseem ceeb tshaj plaws ntawm carbon dioxide lom yog daj ntawm lub ntsis ntiv tes thiab cov plaub hau, nrog rau hnoos, xeev siab, ntuav thiab lwm yam tsos mob. Vim hais tias nitrogen dioxide lom yuav ua rau pulmonary edema hauv qhov raug mob, kev ua pa tsis tuaj yeem siv tau. Yog tias tus resuscitator yuav tsum tau siv los resuscitate, carbon dioxide tsis tuaj yeem tov nrog cov pa ntshiab kom tsis txhob ua rau lub ntsws ntawm cov neeg raug mob. Nws yog qhov zoo tshaj plaws kom cov neeg raug mob ua pa ntawm lawv tus kheej nrog cov pa oxygen muab los ntawm resuscitator.
5. Cov pa roj carbon monoxide lom, ua pa qis thiab ua pa sai, cov pob liab liab ntawm lub plhu thiab lub cev, thiab daim di ncauj liab thaum tsis nco qab. Rau cov neeg raug mob lom, tuaj yeem siv ua pa ua pa lossis oxygen resuscitation. Thaum xa cov pa oxygen, 5% mus rau 7% carbon dioxide tuaj yeem nkag mus rau kev ua pa thiab txhawb nqa kev ua pa rov qab.
Cov khoom siv roj av muaj feem xyuam nrog cov khoom lag luam: Lub tswb ntsuas hluav taws xob sib xyaw, cov khoom siv hluav taws xob ruaj khov, cov khoom siv hluav taws xob ntev ntev standby waterproof thiab tawg-pov thawj portable gas detector
