Note:
SCBA Duration Calculation helps determine how long a Self-Contained Breathing Apparatus cylinder will last based on its pressure, volume, and the user's breathing rate. This is critical for ensuring safety in environments where breathable air is limited.
Understanding the Parameters:
- Cylinder Pressure (Bar): The pressure of the air in the SCBA cylinder, typically measured in Bar (e.g., 300 Bar for a full cylinder).
- Cylinder Volume (Liters): The volume of the SCBA cylinder, typically measured in liters (e.g., 6 liters).
- Breathing Rate (LPM): The rate at which the user consumes air, measured in liters per minute (LPM). A typical breathing rate ranges from 40-60 LPM.
SCBA Cylinder Duration Table
| Cylinder Pressure (Bar) | Cylinder Volume (Liters) | Duration (Minutes) | Notes |
|---|---|---|---|
| 300 | 6 | 45 | Full Pressure |
| 250 | 6 | 37.5 | |
| 200 | 6 | 30 | |
| 100 | 6 | 15 | |
| 50 | 6 | 7.5 | Buzzer or whistle is blown |
