When using rescue lift airbags, boards and plywood must not be used in which locations?

• A. Between or above them
• B. Underneath them
• C. On top of the load
• D. Adjacent to them

Answer: (A)

Airbags must be able to expand and bear the load through a smooth, unobstructed interface. Placing boards or plywood between the bag and the load or above the bag creates a rigid barrier that can pinch or deform the bag, concentrate pressure on edges, trap air, or destabilize the lift. The recommended practice is to use a load-distributing base under the bag to protect the surface and help spread the load, while keeping the area between the bag and the load and anything above the bag clear. That’s why avoiding placement between or above the airbags is the correct guideline.
