شنهای ضد انفجار
این “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).
| دسته بندی وضعیت | طبقه بندی گاز | گازهای نماینده | حداقل انرژی جرقه اشتعال |
|---|---|---|---|
| زیر معدن | من | متان | 0.280mJ |
| کارخانه های خارج از معدن | IIA | پروپان | 0.180mJ |
| IIB | اتیلن | 0.060mJ | |
| IIC | هیدروژن | 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, استیلن, دی سولفید کربن, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, و هیدروژن sulfide. The IIA classification includes gases such as methane, ethane, بنزن, و دیزل.
