What is one of the energy sources commonly used in machinery rescue?

Pneumatic energy is commonly used in machinery rescue because it involves the utilization of pressurized air to operate tools and equipment essential in extrication processes. Pneumatic tools, such as air chisels, air bags, and pneumatic cutters, are favored in the field due to their high power-to-weight ratio, which allows for effective cutting, lifting, and spreading of materials during rescue operations.

Tools powered by pneumatic energy are also readily available and can be quickly deployed in rescue situations, which is critical when time is of the essence. This versatility and efficiency make pneumatic energy a preferred choice among rescue technicians when dealing with machinery extrication scenarios.

Other energy sources like magnetic, solar, and geothermal, while potentially useful in various industrial applications, do not have the same level of practicality or functionality in the context of urgent rescue operations where immediate and effective response is crucial.
