When is the three firefighter flat shoulder carry most appropriate?

The three firefighter flat shoulder carry is most appropriate when the ladder must be carried over short obstacles. This technique allows firefighters to transport the ladder in a flat position, which can be more stable and easier to manage when navigating around hindrances such as curbs or small barriers. The flat shoulder carry helps maintain balance and control over the ladder's center of gravity, making it easier to avoid tipping or dropping the ladder as they move.

In contrast, specific scenarios such as overhead obstructions or narrow spaces require different carrying techniques that prioritize vertical positioning or streamlined shapes. Maneuvering around sharp corners also benefits from techniques that allow for more precise handling and angling of the ladder, rather than maintaining a flat carry. Therefore, the context of carrying the ladder over short obstacles is where the flat shoulder carry is particularly advantageous.
