Why is it unacceptable to tow a soft cam backup device such as a DUCK?

The reason it is unacceptable to tow a soft cam backup device like a DUCK is primarily due to the risk associated with its operation if the main line were to fail. A soft cam backup device is designed to arrest a fall when properly positioned and engaged. However, if it is being towed, there’s a significant risk that it could lock up tightly if the mainline were to give way. This scenario could lead to a much more severe fall than anticipated, as the device may not engage properly to provide the necessary support during a sudden drop.

In situations where the backup device is towed, it is also less likely to remain in the ideal position to function effectively in the event of a fall. The dynamics of the descent could lead to improper alignment or the backup device being unable to engage correctly during a critical moment, compounding the dangers involved. Therefore, this specific concern highlights the importance of proper training and adherence to safety protocols in rope access work, ensuring that backup devices are used correctly to mitigate the risks associated with working at heights.
