What is the maximum pressure of low pressure bags?

The correct answer is based on the industry standards for low pressure bags utilized in various applications, particularly in firefighting and rescue scenarios. Low pressure bags are typically designed to operate effectively at a maximum pressure of 145 psi. This pressure is optimal for ensuring safety and efficacy during their use, allowing for adequate lifting and stabilization without compromising the structural integrity of the bags.

Understanding that a low pressure bag is meant to operate below certain thresholds is crucial for both operational safety and performance reliability. Exceeding this pressure could lead to failures, posing significant risks during critical operations, such as rescue missions. The design specifications for these bags account for a balance between lifting power and safety, ensuring that 145 psi remains the upper limit for effective use.

This aligns with standardized guidelines in safety protocols, ensuring that users are trained accordingly to recognize and operate within these limitations. The other pressures listed may exceed manufacturers' specifications for low pressure bags, which would not reflect their intended and safe operational use.
