The “abc” gaz tasniflarini ifodalaydi, uch darajaga bo'lingan - IIA, Ko'mir, va IIC - maksimal eksperimental xavfsiz bo'shliqqa ko'ra (MESG) yoki minimal yonish oqimi (MIC).
| Vaziyat toifasi | Gaz tasnifi | Reprezentativ gazlar | Minimal yonish uchqun energiyasi |
|---|---|---|---|
| Kon ostida | I | Metan | 0.280mJ |
| Kondan tashqaridagi zavodlar | Iia | Propan | 0.180mJ |
| Ko'mir | Etilen | 0.060mJ | |
| IIC | Vodorod | 0.019mJ |
Shulardan, IIC tasnifi eng xavfli hisoblanadi, IIB va IIA bilan xavfning kamayishi tartibida. IIC tasnifiga kiruvchi gazlarga vodorod kiradi, asetilen, uglerod disulfidi, etil nitrat, va suv gazi. IIB toifasidagilar etilenni o'z ichiga oladi, koks gazi, propin, va vodorod sulfid. IIA tasnifiga metan kabi gazlar kiradi, etan, benzol, va dizel.
