Kev taw qhia txog txoj kev ua haujlwm ntawm cov pa roj toxic detector hauv av
Kev taw qhia txog kev ua haujlwm ntawm cov khoom siv tshuaj lom hauv cov mines hauv av: cov haujlwm tseem ceeb rau txhua tus neeg ua haujlwm hauv av yog hypoxia suffocation, hydrogen sulfide lom thiab combustible gas explosions, thiab feem ntau tshwm sim yog hydrogen sulfide lom. Cov khoom siv hluav taws xob sib xyaw tuaj yeem kuaj xyuas qhov concentration ntawm cov pa phem thiab cov pa phem hauv lub qhov dej hauv lub sijhawm, thiab tuaj yeem ua lub tswb nrov.
1. Cov pa roj carbon dioxide thiab roj suffocation. Ntxiv nrog rau kev ua pa ua pa thiab rov ua kom cov pa oxygen infusion, cov neeg raug mob los ntawm cov pa roj carbon dioxide thiab cov pa roj suffocation yuav tsum rub lawv cov tawv nqaij los yog cia lawv hnov tsw ammonia dej los txhawb kev rov ua pa. lom los ntawm carbon monoxide.
2. Hydrogen sulfide lom. Rau hydrogen sulfide lom, ntxiv rau kev ua pa tawm lossis cov pa oxygen resuscitator, cov khoom paj rwb thiab phuam so hauv cov tshuaj chlorine tuaj yeem muab tso rau hauv lub qhov ncauj. Chlorine yog ib yam khoom zoo rau hydrogen sulfide.
3. sulfur dioxide lom. Vim hais tias sulfur dioxide ntsib cov dej los tsim sulfuric acid, uas muaj zog stimulating nyhuv ntawm lub ntsws 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 gargle nrog dej qab zib daws kom txo tau cov tshuaj lom. Txhawb nqa.
4. Huab cua lom. Cov tsos mob tseem ceeb tshaj plaws ntawm atmospheric dioxide lom yog cov ntiv tes, daj ntawm cov plaub hau, thiab cov tsos mob xws li hnoos, xeev siab, thiab ntuav. 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 rau resuscitation, cov pa ntshiab tsis tuaj yeem tov nrog carbon dioxide kom tsis txhob ua rau lub ntsws ntawm cov neeg raug mob. Cia tus neeg raug mob ua pa tsis tu ncua, nyiam dua nrog cov pa oxygen los ntawm tus neeg sawv cev.
5. Carbon monoxide lom, ua pa ntiav thiab nrawm, erythema ntawm sab plhu thiab lub cev thaum tsis nco qab, daim di ncauj liab. Artificial respiration los yog oxygen xa nrog lub resuscitator tuaj yeem siv rau cov neeg raug mob lom. Thaum infusing oxygen, 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.
Cov khoom lag luam muaj feem xyuam ntawm cov khoom siv hluav taws xob: Cov khoom siv hluav taws xob sib xyaw thiab lub tswb ntsuas, 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
