What type of environment is the two-person seat carry particularly challenging in?

The two-person seat carry is particularly challenging in confined spaces due to the limited maneuverability and restricted movement that such environments present. In confined spaces, firefighters often have to navigate tight corners, low ceilings, and narrow passageways. This can make it difficult for two rescuers to maintain proper positioning and coordination while executing the carry. The close quarters can hinder their ability to effectively communicate and adjust their hold on the person being carried, increasing the risk of accidents or injury.

In contrast, open fields, urban areas, and hilly terrains may present their own unique challenges, such as uneven ground or obstacles, but they generally allow for more space and easier movement compared to confined spaces. The spatial constraints of confined settings significantly increase the complexity of performing a two-person seat carry safely and effectively.
