Which type of rescue carry down an aerial ladder is the most dangerous for the responder?

The over-the-shoulder carry is considered the most dangerous rescue carry down an aerial ladder primarily due to the unstable positioning of the responder and the victim. In this carry method, the responder has to secure the victim over their shoulder while balancing on the ladder. This position can hinder the responder's ability to maintain stability, as their center of gravity shifts when carrying the additional weight in a way that may require them to lean forward or sideways for balance.

Moreover, the visibility is limited in this position, which can impede the responder's ability to navigate the ladder safely, especially if there are obstacles or other firefighters present. The potential for losing grip or misstepping increases, raising the risk of falling or dropping the victim.

In contrast, other carries such as the under-the-arm carry or legs-first carry usually allow for more control and visibility while maneuvering down the ladder. These techniques distribute weight differently and help maintain a better center of gravity, contributing to safety during the descent. Thus, while all carries entail some risk, the over-the-shoulder method stands out as particularly hazardous in this context.
