Acid Gas Respirator: Txhais thiab Ua Haujlwm
Lub tshuab pa roj pa yog ib yam khoom siv tiv thaiv ua pa tshwj xeeb uas tsim los lim tawm cov pa phem, xws li hydrogen chloride (HCl), sulfur dioxide (SO₂), lossis chlorine (Cl₂). Cov pa roj no muaj nyob rau hauv ib puag ncig kev lag luam xws li cov nroj tsuag tshuaj, refineries, thiab cov chaw soj nstuam, qhov uas raug rau cov tshuaj lom lossis corrosive yog qhov txaus ntshai.
Nws ua haujlwm li cas:
Acid gas respirators feem ntau siv cov ntawv tshwj xeeb lossis cov lim dej uas muaj cov khoom xws li alkaline tshuaj uas ua rau cov kua qaub kua qaub thaum lawv hla. Qhov no yuav pab tiv thaiv kom tsis txhob nqus cov tshuaj phem, tiv thaiv kev ua pa. Lawv feem ntau yog ib feem ntawm lub tshuab ua pa kom huv, txhais tau tias lawv tso siab rau cov lim dej los ntxuav cov huab cua ua ntej tus neeg hnav nws ua pa.
Daim ntawv thov:
Cov tshuab ua pa no yog siv rau hauv ib puag ncig uas cov neeg ua haujlwm tuaj yeem raug cov pa roj carbon monoxide, suav nrog kev lag luam xws li:
Kev tsim tshuaj
Petrochemical refining
Pulp thiab ntawv ntau lawm
Laboratories soj ntsuam nrog corrosive chemicals
Kev tiv thaiv thiab kev txwv:
Txawm hais tias cov pa roj pa roj ua pa muaj kev tiv thaiv tseem ceeb tiv thaiv cov pa phem, lawv tsis haum rau ib puag ncig uas tsis muaj oxygen txaus lossis rau cov teeb meem hauv huab cua ntau dua li cov teeb meem me me. Nws tseem yog ib qho tseem ceeb los xyuas kom meej qhov haum thiab tsis tu ncua ntawm cov ntxaij lim dej kom muaj kev tiv thaiv zoo.
