Shenhai Explosion-Proof
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).
| Шарт категориясы | Газдын классификациясы | Өкүл газдар | От алдыруу учкунунун минималдуу энергиясы |
|---|---|---|---|
| Кендин астында | И | Метан | 0.280мЖ |
| Кендин сыртындагы заводдор | IIA | Пропан | 0.180мЖ |
| IIB | Этилен | 0.060мЖ | |
| IIC | Суутек | 0.019мЖ |
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, ацетилен, carbon disulfide, ethyl nitrate, and water gas. Those in the IIB category encompass ethylene, coke oven gas, propyne, жана суутек sulfide. The IIA classification includes gases such as methane, этан, бензол, жана diesel.
