氟气 Detection
Formula F₂ · CAS 7782-41-4 · 极强氧化性 / 极腐蚀 / 极毒
Hazards & Toxic Symptoms
Fluorine gas is a light yellow irritating gas, the strongest oxidant, and reacts with almost all elements (except for a few inert gases). It is extremely toxic and corrosive. Skin contact can cause immediate chemical burns. Even 1 ppm can cause irritation.
Occupational Exposure Limits (GBZ 2.1-2019)
| PC-TWA (Time-Weighted Average) | 0.2 mg/m³ |
|---|---|
| IDLH (Immediately Dangerous to Life or Health) | 25 ppm |
