What is the maximum number of air bags that should be stacked?

The correct answer is based on the safety protocols established for handling air bags during rescue operations or vehicle extrication. Stacking air bags beyond the recommended maximum can compromise their effectiveness and may increase the risk of accidents or injuries.

Stacking two air bags is often considered optimal because it provides additional lift and stability while still allowing for safe operation. The primary concern during a rescue situation is maintaining control over the lift and ensuring the safety of both the rescuers and any trapped victims. More than two air bags can lead to an unstable load and may make it difficult to manage if there is a sudden shift.

This principle is essential in vehicle rescue operations where precision is necessary, and any unpredictable movement could pose significant risks. Keeping the stack to a maximum of two ensures that both the lifting capacity and the control remain within safe operational limits.
