When using pneumatic air bags to perform a lift to free a victim, never stack more than _____________ bags.

When using pneumatic air bags to perform a lift in rescue operations, it is vital to ensure safety and stability during the lifting process. Stacking more than two bags can introduce significant risks. Each additional bag adds complexity to the operation and increases the chance of failure under load.

Having two bags allows for a balance between achieving the necessary lift height and maintaining stability. This is particularly important because pneumatic bags have specific weight capacities and limitations, and exceeding the recommended number could compromise their ability to hold air pressure effectively and sustain the load.

Proper training emphasizes adhering to the manufacturer’s guidelines regarding the use of air bags, which typically advise not stacking more than two for safe operation. This approach minimizes potential hazards not only to the victim being rescued but also to the rescuers involved.
