二氧化碳 Detection
Formula CO₂ · CAS 124-38-9 · 窒息性 / 大气污染物
Hazards & Toxic Symptoms
Carbon dioxide is a colorless, odorless, slightly acidic gas that is 1.5 times heavier than air. Concentrations in the air > 1% can cause headaches, > 5% can lead to breathing difficulties, and > 10% can result in loss of consciousness or even death. It is the primary greenhouse gas.
Occupational Exposure Limits (GBZ 2.1-2019)
| PC-TWA (Time-Weighted Average) | 9000 mg/m³ |
|---|---|
| IDLH (Immediately Dangerous to Life or Health) | 40000 ppm (4%) |
