| Category | Details |
|---|---|
| Composition | – Nitrogen (N₂): Balance gas (typically 70–95% by volume) |
| – Carbon Monoxide (CO): 1–5000 ppm (toxic, combustion byproduct) | |
| – Propane (C₃H₈): 0.5–5% (flammable hydrocarbon fuel) | |
| Key Applications | – Environmental Science: Air quality monitoring (CO emissions, VOCs) |
| – Industrial Safety: Calibrating multi-gas detectors (CO/flammables) | |
| – Welding: Oxy-fuel cutting (C₃H₈ as fuel, N₂ as buffer) | |
| – Fuel Research: Combustion efficiency testing (CO/C₃H₈ mixtures) | |
| Physical Properties | – CO: Colorless, odorless, toxic gas (density ≈1.145 kg/m³) |
| – C₃H₈: Flammable gas (explosive range: 2.1–9.5% in air) | |
| – N₂: Inert buffer; prevents oxidation | |
| Safety Precautions | – Toxicity: CO requires ventilation and real-time monitoring (≤25 ppm TWA) |
| – Fire Risk: Eliminate ignition sources; store away from oxidizers | |
| – Asphyxiation: High N₂/C₃H₈ levels displace oxygen; monitor O₂ sensors | |
| Storage & Handling | – High-pressure cylinders (e.g., 50L, 100L) at 150–200 bar pressure |
| – Store upright in cool, well-ventilated areas; secure against falls | |
| – Liquid propane requires DOT-certified containers (cryogenic handling) | |
| Certifications | Compliance with ISO 17025 (calibration), OSHA/EPA regulations, and ASTM D1835 (LPG safety) |
| Environmental Impact | – CO: Contributes to smog and ground-level ozone |
| – C₃H₈: Greenhouse gas (GWP ≈20); non-toxic but flammable | |
| Shelf Life | 12–24 months when stored at 15–25°C (avoid temperature fluctuations) |
| Special Notes | – Mixture Stability: Agitate cylinders before use to homogenize gas |
| – Leak Detection: Use gas sniffer tools (avoid open flames) |
