Menene Matsayin Tabbacin Fashewa ABC yake nufi

The “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).

Matsayin Yanayin	Rarraba Gas	Gas na wakilci	Mafi qarancin Ignition Spark Energy
Karkashin The Mine	I	Methane	0.280mJ
Masana'antu A Waje Ma'adanan	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	Hydrogen	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, acetylene, carbon disulfide, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, kuma hydrogen sulfide. The IIA classification includes gases such as methane, ethane, benzene, kuma diesel.
