What must be engaged before resetting the Mechanical Advantage System (MAS) when raising a load?

Before resetting the Mechanical Advantage System (MAS) when raising a load, it is crucial to engage the safety ratchet. The safety ratchet acts as a brake that prevents the load from descending inadvertently once the system is disengaged. This is important because if the MAS is reset without securing the load with a safety mechanism, the load could fall unexpectedly, leading to potential injury or equipment damage.

In situations where a load is being raised, it's essential to have a reliable system in place that maintains control and safety throughout the process. The safety ratchet provides that added layer of security by ensuring that once the load is elevated, it will not slip back down the rope while adjustments or resets are being made.

While the main anchor, load line, and return line are all critical components of the rope rescue setup, they do not provide the specific safety function that the safety ratchet does in the context of resetting the MAS. Engaging the main anchor secures the entire system to a stable point, but it does not prevent movement of the load itself. Similarly, the load line is responsible for lifting the load, and the return line is used for certain mechanical operations, but neither directly adds to the safety of the load during the reset process. Thus, the
