Hot Air Balloons

Hot air balloons are a popular recreational and adventure activity, relying on industrial gases for inflation, lift control, and safe operation. The primary gases used in hot air ballooning include propane (C₃H₈) and helium (He), each playing a unique role in enabling flight stability, altitude control, and safety.

High-Altitude Sports & Mountaineering

In aviation sports such as skydiving, paragliding, and high-altitude climbing, oxygen (O₂) tanks are used for breathing at high elevations. Mountaineers climbing peaks above 5,000 meters (16,400 feet) rely on portable oxygen cylinders to prevent altitude sickness and hypoxia.
