Qhov txawv ntawm Explosion-Proof Level AT BT CT

Ua ntej, tag nrho peb cov khoom siv yog tsim los tiv thaiv plua plav tawg thiab poob rau hauv qeb ntawm cov khoom siv hluav taws xob tawg. Cov kev ntsuas tawg-pov thawj yog raws li hauv qab no: AT < BT < CT.

Hom mob	Gas Classification	Cov pa hluav taws xob	Yam tsawg kawg nkaus Ignition Spark Zog
Sub Kuv	Kuv	Methane	0.280mJ
Factories sab nraum lub Mine	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	Hydrogen	0.019mJ

CT cov cuab yeej muaj qhov zoo tshaj qhov pov thawj plua plav thiab tej zaum yuav siv tau rau hauv cov cheeb tsam uas tsim los rau AT thiab BT. Txawm li cas los, Cov khoom siv AT thiab BT tsis haum rau cov cheeb tsam uas xav tau cov qauv CT.

Hauv lwm lo lus, Cov khoom siv CT tuaj yeem hloov pauv rau AT thiab BT, tab sis AT thiab BT cov khoom siv tsis tuaj yeem hloov CT.
