Patlamaya Dayanıklı Seviye ABC Ne Demektir?

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).

Durum Kategorisi	Gaz Sınıflandırması	Temsili gazlar	Minimum Ateşleme Kıvılcım Enerjisi
Madenin Altında	BEN	Metan	0.280mJ
Maden Dışındaki Fabrikalar	IIA	Propan	0.180mJ
	IIB	Etilen	0.060mJ
	IIC	Hidrojen	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, asetilen, karbon disülfür, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, Ve hidrojen sulfide. The IIA classification includes gases such as methane, etan, benzen, Ve diesel.
