Shenhai Kuputika-Uchapupu
Kuputika-proof midziyo mukati meKirasi II yakakamurwa kuita: Kirasi IIA, Kirasi IIB, uye Kirasi IIC. Iwo maresheni anotevera hierarchy: IIC > IIB > IIA.
| Condition Category | Gasi Classification | Anomiririra magasi | Minimum Ignition Spark Energy |
|---|---|---|---|
| Under The Mine | I | Methane | 0.280mJ |
| Mafekitori Kunze Kwemugodhi | IIA | Propane | 0.180mJ |
| IIB | Ethylene | 0.060mJ | |
| IIC | Hydrogen | 0.019mJ |
Magetsi emagetsi akatemerwa IIC kuputika-proof mamiriro akakodzera kune ese anopfuta magasi; zvisinei, IIB detectors inotadza kuona H2 (hydrogen), C2H2 (acetylene), uye CS2 (carbon disulfide), izvo hunhu hweIIC kirasi.
