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).
Kitengo cha Masharti | Uainishaji wa gesi | Mwakilishi wa gesi | Nishati ya Kima cha chini cha Cheche cha Kuwasha |
---|---|---|---|
Chini ya Mgodi | I | Methane | 0.280mJ |
Viwanda Nje ya Mgodi | IIA | Propane | 0.180mJ |
IIB | Ethilini | 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, asetilini, carbon disulfide, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, na hidrojeni sulfide. The IIA classification includes gases such as methane, ethane, benzene, na diesel.
