What Does Explosion-Proof Level ABC Mean

Të “abc” represents gas classifications, categorized into three levels—IIA, IIB, and IIC—according to the maximum experimental safe gap (MESG) or the minimum igniting current (MIC).

Kategoria e gjendjes	Klasifikimi i gazit	Gazet përfaqësuese	Energjia minimale e ndezjes së ndezjes
Nën Minierën	I	Metani	0.280mJ
Fabrika jashtë minierës	IIA	Propani	0.180mJ
	IIB	Etileni	0.060mJ
	IIC	Hidrogjeni	0.019mJ

Of these, the IIC classification is deemed the most hazardous, with IIB and IIA following in decreasing order of risk. Gases falling under the IIC classification include hydrogen, acetilen, disulfidi i karbonit, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, dhe hidrogjeni sulfide. The IIA classification includes gases such as methane, ethane, benzenit, dhe diesel.
