7. Safety Information: Hazards of Ammonia
Ammonia (NH3) is a hazardous gas. Understanding its concentration levels and associated risks is crucial for safety. The AP-9000B helps monitor these levels to prevent exposure to dangerous concentrations.
| Concentration (PPM) | Perill potencial |
|---|---|
| 5 ppm | Sensory odor threshold; some individuals may detect it. |
| 20 ppm | Significant irritation in most people, generally not harmful with short exposure. |
| 20-30 ppm | Time-weighted safety thresholds for occupational exposure. |
| 100 ppm | Discomfort for most people, not harmful with limited exposure. |
| 250 ppm | Irritation of nose, throat, eyes, and other senses. |
| 400 ppm | Eye pain, tearing for 30 minutes. |
| 700 ppm | Limit of human tolerance; prolonged exposure should be avoided. |
| 2500 ppm | Intense coughing, irritation of nose, throat, etc.; may lead to death in 15 minutes. |
| 5000 ppm | Causes spasmodic dyspnea, asphyxiation, and rapid death. |
