When using pneumatic airbags to perform a lift, how many bags should never be stacked?

Using pneumatic airbags for lifting operations requires careful adherence to safety protocols and manufacturer guidelines. The correct number of bags that should never be stacked is two. This is rooted in the potential risks associated with stacking too many bags, which could lead to instability during the lift or even catastrophic failure under load.

When using pneumatic airbags, they are designed to distribute weight evenly and provide a certain amount of lift based on their size and rating. Stacking bags can create uneven pressure distribution, which may compromise the structural integrity of the bags and the overall safety of the lift. By limiting the stacking to only one bag, firefighters ensure they maintain a stable lifting platform, reducing the risk of accidents.

This safety guidance is based on engineering principles that emphasize the importance of maintaining a balanced and controlled lifting operation. It’s vital for first responders to recognize the limitations of equipment and adhere to best practices to ensure safety during emergency operations.
