Kev taw qhia txog kev khiav hauj lwm cov pa roj toxic detectors underground
Cov lus qhia rau kev khiav hauj lwm cov pa tshuaj lom neeg nyob hauv av: Lub luag haujlwm tseem ceeb rau txhua tus neeg ua haujlwm hauv av yog hypoxia thiab suffocation, hydrogen sulfide lom, thiab cov roj combustible explosion, ntawm cov phenomenon yog hydrogen sulfide lom. Lub tshuab hluav taws xob sib xyaw tuaj yeem tshawb xyuas lub sijhawm ntawm cov pa phem thiab cov pa phem hauv lub qhov dej, thiab tuaj yeem tswb.
1. Cov pa roj carbon dioxide thiab roj suffocation. Kev raug mob los ntawm cov pa roj carbon dioxide thiab cov pa roj suffocation uas tau simulated tuag, ntxiv rau kev ua pa ua pa thiab oxygen resuscitation, kuj yuav tsum tau txhuam lawv cov tawv nqaij lossis ua rau lawv hnov ntxhiab ammonia los txhawb kev rov ua pa. Cov pa roj carbon monoxide lom.
2. Hydrogen sulfide lom. Hydrogen sulfide lom: Ntxiv nrog rau kev ua pa los yog kev kho pa oxygen nrog lub tshuab tsim dua tshiab, paj rwb swabs, phuam so tes, thiab lwm yam. soaked hauv dej tshuaj chlorine tuaj yeem muab tso rau hauv lub qhov ncauj. Chlorine yog ib yam khoom zoo ntawm hydrogen sulfide.
3. sulfur dioxide lom. Vim muaj cov tshuaj tiv thaiv muaj zog ntawm sulfur dioxide rau ntawm lub ntsws vim nws tsim cov sulfuric acid thaum nws los rau hauv dej, nws yuav ua rau kub hnyiab heev. Yog li ntawd, ntxiv rau kev ua pa ua pa lossis oxygen infusion los ntawm cov cuab yeej resuscitation, cov neeg muaj tshuaj lom yuav tsum tau muab mis nyuj, zib ntab, los yog yaug nrog dej qab zib kom txo tau qhov khaus.
4. Ua pa phem los ntawm atmospheric dioxide. Cov pov thawj tseem ceeb tshaj plaws ntawm cov tshuaj lom dioxin yog daj ntawm cov ntiv tes thiab cov plaub hau, nrog rau cov tsos mob xws li hnoos, xeev siab, thiab ntuav. Vim tias nitrogen dioxide lom tuaj yeem ua rau lub ntsws edema hauv cov neeg raug mob, kev ua pa tsis tuaj yeem siv tau. Yog tias tsim nyog siv cov cuab yeej rov yug dua tshiab, cov pa roj carbon dioxide tsis tuaj yeem ntxiv rau cov pa ntshiab kom tsis txhob ua rau lub ntsws ntawm cov neeg raug mob * Qhov zoo yog ua kom tus neeg raug mob ua pa autonomously nrog oxygen muab los ntawm tus resuscitator.
5. Cov pa roj carbon monoxide lom, ua pa qis thiab ua pa nrawm, cov pob liab liab ntawm lub puab tsaig thiab lub cev thaum tsis nco qab, thiab daim di ncauj liab. Cov neeg mob uas muaj tshuaj lom tuaj yeem kho nrog kev ua pa ua pa lossis kev kho pa oxygen siv lub resuscitator. Thaum lub sij hawm oxygen infusion, 5 feem pua rau 7 feem pua cov pa roj carbon dioxide tuaj yeem nkag mus rau kev ua pa thiab txhawb kev rov ua haujlwm ntawm kev ua pa.
