What Does Explosion-Proof Level ABC Mean

Awọn “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).

Ipò Ẹka	Gaasi Classification	Awọn gaasi aṣoju	Kere iginisonu Spark Energy
Labẹ The Mi	I	Methane	0.280mJ
Factories Ita The Mine	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, erogba disulfide, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, ati hydrogen sulfide. The IIA classification includes gases such as methane, ethane, benzene, ati diesel.
