What are the three types of commonly used pneumatic rescue lift airbags?

• A. Soft, medium, and hard
• B. Low, medium, and high pressure
• C. Light, standard, and heavy
• D. Low, high, and extreme pressure

Answer: (B)

Pneumatic rescue lift bags are categorized by the pressure range they’re designed to use. This matters because the amount of lift, the speed of inflation, and the space required to place the bag all depend on pressure. Low-pressure bags use a larger air volume to lift gradually and with great stability. They’re helpful when you have room under the load and you want a controlled, steady lift without quick surges. Medium-pressure bags strike a middle ground, offering quicker inflation and a good amount of lift without needing as much air volume as the low-pressure variety. High-pressure bags deliver more lifting force from a smaller air volume, which is advantageous in tight spaces or when you need faster lift. Understanding these three types helps you choose the right tool for the scene. Other terms in the choices don’t reflect how rescue airbags are typically classified by pressure, so they aren’t used in standard practice.
