Dab tsi yog kev faib tawm ntawm compressed gas cylinders?

Compressed gas cylinders yog ib qho tseem ceeb ntawm ntau qhov kev lag luam, muab lub zog, roj thiab lwm yam khoom siv. Txawm li cas los xij, cov thooj voos kheej kheej no tuaj yeem ua rau muaj kev phom sij loj yog tias tsis ua haujlwm zoo, yog li nws yog qhov tseem ceeb kom nkag siab txog lawv cov kev faib tawm.

Compressed gases raug cais raws li lawv qhov muaj peev xwm txaus ntshai, uas yog txiav txim siab los ntawm kev ntsuas qhov tuag concentration (LC50) ntawm txhua cov pa hauv 50% ntawm cov tsiaj sim (nas). Cov txheej txheem kev faib tawm tau muab faib ua plaub pawg, nrog Pawg Kuv yog qhov txaus ntshai tshaj plaws thiab Qeb IV yog qhov txaus ntshai tshaj plaws.

Class I gases muaj xws li cov pa roj uas muaj tshuaj lom heev, kub heev, los yog ob qho tib si. Cov pa roj no ua rau muaj kev pheej hmoo loj rau tib neeg kev noj qab haus huv thiab kev nyab xeeb thiab yuav tsum tau ceev faj heev. Class I gases muaj xws li hydrogen cyanide, ammonia, thiab chlorine.

Class II gases kuj muaj tshuaj lom lossis flammable, tab sis tsawg dua li Class I gases. Cov pa roj no tseem suav tias muaj kev phom sij thiab yuav tsum tau ua tib zoo tuav. Class II gases muaj xws li carbon monoxide, propane, thiab acetylene.

Class III gases muaj teeb meem me ntsis thiab tej zaum yuav muaj irritants lossis asphyxiants. Txawm hais tias tseem muaj kev phom sij yog tias siv tsis raug, Class III gases feem ntau tsis tshua muaj tshuaj lom lossis ua rau muaj hluav taws ntau dua li Class I thiab II gases. Piv txwv ntawm Class III gases muaj xws li nitrogen, helium, thiab carbon dioxide.

Thaum kawg, Class IV gases yog suav tias yog tsis muaj kev phom sij thiab tej zaum yuav muaj xws li inert gases xws li argon los yog neon. Yog tias ua tau zoo, cov pa roj no ua rau muaj kev pheej hmoo me ntsis rau tib neeg kev noj qab haus huv lossis kev nyab xeeb.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum cov kev faib tawm no feem ntau lees txais, qee lub koom haum tswj hwm hauv zos yuav siv cov txheej txheem sib txawv. Tsis tas li ntawd, kev tuav thiab khaws cia ntawm lub tog raj kheej roj compressed yuav tsum tau ua raws li cov txheej txheem tsim nyog thiab cov cai. Kev tuav thiab khaws cia cov pa roj carbon monoxide zoo tuaj yeem pab tiv thaiv kev sib tsoo, suav nrog cov uas ua rau tawg, hluav taws kub, lossis tso tawm cov pa phem.

Nyob rau hauv cov ntsiab lus, compressed gas cylinders raug cais raws li lawv tej zaum yuav muaj kev phom sij, nrog Class I yog qhov teeb meem tshaj plaws thiab Class IV qhov teeb meem tsawg tshaj plaws. Kev nkag siab txog cov kev faib tawm no thiab cov txheej txheem tuav thiab khaws cia kom zoo tuaj yeem pab xyuas kom muaj kev nyab xeeb ntawm kev siv cov roj compressed hauv ntau qhov kev lag luam.
