Which bag type has a maximum air pressure of 7 psi?

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

Answer: (A)

Understanding how airbag systems are categorized in vehicle rescue is key. The maximum inflation pressure is a defining trait. Low-pressure bags are designed to lift and stabilize with a gentle, controlled inflation, capped at about 7 psi. This makes them ideal for delicate components and for making small, slow adjustments without risking bag rupture or pushing the vehicle in unintended directions. The other bag types are built for higher pressures: medium-pressure bags require more force to lift bigger loads, high-pressure bags are used when substantial lift is needed in tight spaces, and multi-cell high-pressure bags spread the lifting force across several cells for heavier or more complex situations. So when the goal is a calm, controlled lift with minimal risk, low-pressure bags are the correct choice.
