🧯 SCBA – Self-Contained Breathing Apparatus
A Self-Contained Breathing Apparatus (SCBA) is a life-saving respirator that provides clean, breathable air from a compressed cylinder. It’s commonly used by firefighters and rescue workers in environments filled with smoke, toxic gases, or low oxygen.
⚙️ Key Specifications Explained
🏷️ Model & Brand
- Brand: JiangGu
- Origin: Jiangsu, China
👉 This identifies the exact configuration and manufacturer.
🧯 Application
- Use Case: Firefighting & emergency rescue
👉 Designed for hazardous environments such as:
- Fire incidents (smoke inhalation protection)
- Chemical spills
- Confined space rescue
💨 Air Supply System
- Cylinder Volume: 6.8 Liters
- Working Pressure: 30 MPa (≈ 300 bar)
👉 This means:
- The cylinder stores highly compressed air.
- Typically provides ~60 minutes of breathing time, depending on usage rate.
⚖️ Weight
- Total Weight: 16 kg
👉 Includes:
- Air cylinder
- Harness/backplate
- Regulator system
- Face mask
This is standard for professional SCBA units.
🫁 Breathing Function
- Type: Reusable, Positive Pressure
👉 Positive pressure system means:
- Air pressure inside the mask is always slightly higher than outside.
- Prevents toxic gases from leaking into the mask.
🧩 Main Components
Typical SCBA units like this include:
- Air cylinder (6L compressed air tank)
- Pressure regulator
- Full-face mask
- Harness/backplate
- Pressure gauge & alarm (low-air warning)
⚡ Key Advantages
- ✔ Reliable breathable air in toxic environments
- ✔ Positive pressure prevents contamination
- ✔ Reusable (refillable cylinder)
- ✔ Durable for extreme conditions
⚠️ Important Considerations
- Requires training to use safely
- Needs regular inspection and maintenance
- Cylinders must be properly refilled and pressure-tested
