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).
Condition Category | Gasi Gulu | Woimira mpweya | Minimum Ignition Spark Energy |
---|---|---|---|
Pansi pa Mgodi | Ine | Methane | 0.280mJ |
Mafakitole Kunja Kwa Mgodi | IIA | Propane | 0.180mJ |
IIB | Ethylene | 0.060mJ | |
IIC | haidrojeni | 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, ndi haidrojeni sulfide. The IIA classification includes gases such as methane, ethane, benzene, ndi dizilo.
