What is a common downside of using low pressure bags in lifting?

Using low pressure bags in lifting typically comes with the downside of having a lower maximum lift compared to high pressure bags. This means that while low pressure bags can be effective for certain applications, they may not be capable of lifting heavier loads as efficiently as their high pressure counterparts. High pressure bags are designed to offer greater lifting strength because they operate at higher pressures, allowing them to support more weight and provide more versatility in lifting operations. This characteristic makes them more suitable for heavy-duty lifts, while low pressure bags may struggle to achieve the same lifting capacity.

The other options do not correctly represent the main drawback of low pressure bags. For example, they can be suitable for light loads, may not necessitate extensive training compared to other lifting methods, and can be quite durable with appropriate care. However, the limitation in maximum lift is a fundamental characteristic of low pressure lifting systems.
