• Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death. • If the refrigerant gas leaks during installation, ventilate the area immediately.

Natural Gas Leak Detection in Pipelines

Since methane is much lighter than air, the density difference provides a signature that can be used as an indicator of a potential leak. Backscatter imaging utilizes a carbon-dioxide laser to illuminate the area above the pipeline. The natural gas scatters the laser light very strongly.

A leak in the air brake system which causes all the air to be lost will also cause the springs to put on the brakes. Tractor and straight truck spring brakes will come fully on when air pressure drops to a range of 20 to 45 psi (typically 20 to 30 psi). Do
