环氧乙烷 Detection
Formula C₂H₄O · CAS 75-21-8 · 致癌物（IARC 1 类）/ 极易燃极易爆 / 高毒
Hazards & Toxic Symptoms
Ethylene oxide (EO/ETO) is a colorless, sweet-smelling gas that is carcinogenic, teratogenic, and mutagenic. It is highly flammable and forms explosive mixtures with air across almost the entire range (3-100%).
Occupational Exposure Limits (GBZ 2.1-2019)
| PC-TWA (Time-Weighted Average) | 2 mg/m³ |
|---|---|
| IDLH (Immediately Dangerous to Life or Health) | 800 ppm |
| LEL (Lower Explosive Limit) | 3% |
| UEL (Upper Explosive Limit) | 100% |
⚠️ Actual alarm thresholds depend on on-site risk assessment. ⚙️ Use the GB Alarm Calculator →
