Toxic gas detector nyob rau hauv txoj kev ua haujlwm hauv av qhia
Cov pa roj carbon monoxide detector nyob rau hauv txoj kev ua haujlwm zoo kev taw qhia: lub luag haujlwm tseem ceeb ntawm txhua tus neeg ua haujlwm hauv lub qhov dej yog qhov tsis muaj oxygen asphyxia, hydrogen sulfide lom thiab cov pa tawg, uas * qhov tshwm sim tshwm sim yog hydrogen sulfide lom. Composite gas detector tuaj yeem ntes cov concentration ntawm cov pa phem thiab cov pa phem hauv lub qhov dej hauv lub sijhawm, thiab tuaj yeem ua lub tswb nrov.
1, carbon dioxide thiab roj asphyxiation. Cov pa roj carbon dioxide thiab roj asphyxiation tshwm sim los ntawm kev tuag tsis tseeb ntawm cov neeg raug tsim txom, ntxiv rau kev ua pa ntawm kev ua pa thiab suxan oxygen kis, tab sis kuj ua rau lawv cov tawv nqaij los yog ua rau lawv hnov ntxhiab ammonia, txhawm rau txhawb kev rov ua pa. Cov pa roj carbon monoxide lom.
2, hydrogen sulfide lom. Hydrogen sulfide lom ntxiv rau kev ua pa tawm lossis suxo hloov pauv ntawm cov pa oxygen, tuaj yeem tsau rau hauv cov tshuaj chlorine ntawm cov paj rwb, phuam phuam, thiab lwm yam rau hauv lub qhov ncauj, chlorine yog cov tshuaj hydrogen sulfide zoo.
3, sulfur dioxide lom. Raws li sulfur dioxide nyob rau hauv dej rau hauv sulfuric acid, lub ua pa system muaj ib tug muaj zog stimulating nyhuv, tej zaum yuav ua rau mob hnyav, yog li ntxiv rau kev siv cov pa ua pa los yog nqus cov pa oxygen, yuav tsum tau muab rau cov mis nyuj uas raug mob, zib ntab, los yog yaug. lub qhov ncauj nrog dej qab zib kom txo tau qhov stimulation.
4, dioxide lom. Dioxide lom * cov pov thawj tseem ceeb ntawm cov ntiv tes, cov plaub hau daj, thiab hnoos, xeev siab, ntuav thiab lwm yam tsos mob. Vim tias muaj nitrogen dioxide lom, yuav ua rau cov neeg mob ntsws pulmonary edema, thiab yog li ntawd tsis tuaj yeem siv ua pa ua pa, yog tias koj yuav tsum siv lub tshuab nqus tsev nqus, nyob rau hauv cov pa ntshiab tsis tuaj yeem tov nrog carbon dioxide, kom tsis txhob stimulation ntawm cov neeg raug mob lub ntsws. . * Nws yog qhov zoo los ua kom cov neeg raug mob tuaj yeem ua pa ntawm nws tus kheej hauv qab cov pa oxygen los ntawm lub tshuab nqus tsev.
5. Cov pa roj carbon monoxide lom, ua pa qis thiab ua pa nrawm, cov pob liab liab ntawm lub plhu thiab lub cev thaum tsis nco qab, thiab daim di ncauj xim peach. Artificial respiration tuaj yeem siv rau cov neeg raug mob lom lossis cov pa oxygen tuaj yeem siv nrog lub tshuab nqus tsev. Cov pa tuaj yeem nkag mus rau hauv 5% mus rau 7% ntawm cov pa roj carbon dioxide, txhawm rau txhawb kev ua pa zoo thiab txhawb kev rov ua haujlwm ntawm kev ua pa.
