What must be carried at all times when using ascending devices?

When using ascending devices, it is essential to carry foot loops at all times. Foot loops are crucial for providing the necessary support and stability while ascending, as they allow the technician to gain additional leverage and facilitate the climbing process. They enable the user to engage their legs more effectively, reducing the burden on their upper body and allowing for a more efficient climbing technique.

In rope access work, safety and efficiency are paramount, and foot loops contribute directly to these factors. They help the individual maintain proper body positioning and balance, especially when navigating vertical or near-vertical surfaces. Without adequate foot loops, it becomes much more difficult to ascend safely and effectively.

While a harness is a vital piece of equipment for any rope access work, it does not specifically aid in the act of ascending and is therefore not the primary necessary item in this context. A first-aid kit and spare rope are also important for safety and emergency situations, but they do not directly relate to the climbing technique and the mechanics of ascending with devices.
