When using pneumatic airbags to perform a lift, you should never stack more than ___ bags.

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (A)

Pneumatic airbags are used to lift with a stable, controlled motion, and the main safety factor is keeping the lift safe and manageable as you raise the load. Stacking more than two bags makes the setup taller and more top-heavy, which makes it harder to control and increases the risk that the load will shift, tilt, or that a bag could slip or fail. Limiting to two bags keeps the weight distributed over a solid base and maintains better stability during inflation. If a greater lift is needed, use alternative methods to gain height—such as cribbing or adjusting the arrangement so bags are placed side-by-side rather than stacked—while following manufacturer guidelines.
