Il- “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).
Kategorija ta' Kundizzjoni | Klassifikazzjoni tal-Gass | Gassijiet rappreżentattivi | Enerġija Minima ta' Spark ta' Tqabbid |
---|---|---|---|
Taħt Il-Minjiera | I | Metanu | 0.280mJ |
Fabbriki Barra Il-Minjiera | IIA | Propan | 0.180mJ |
IIB | Etilene | 0.060mJ | |
IIC | Idroġenu | 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, aċetilena, disulfide tal-karbonju, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, u idroġenu sulfide. The IIA classification includes gases such as methane, etan, benżin, u diżil.
