Which bag type has a working pressure of 150-174 psi?

• A. Low-pressure bags
• B. Medium-pressure bags
• C. High-pressure bags
• D. Multi-cell high-pressure bags

Answer: (D)

Working pressure ratings reflect the amount of force a bag can safely exert to lift or stabilize a load. When you need the highest available pressure in a rescue bag system, a multi-cell high-pressure bag is used. Its multiple interconnected cells can be inflated to around 150–174 psi, providing strong lifting capacity in tight spaces while distributing the load across several cells for stability. Low-pressure bags deliver much less force and are used for lighter tasks; medium-pressure bags sit in between; standard high-pressure bags offer higher pressure than the low and medium options but generally not at the elevated level of a multi-cell high-pressure setup. Thus, reaching the 150–174 psi range is a specialty of multi-cell high-pressure bags.
