Which feature is NOT part of the Rescue 42 safety features?

The feature that is not part of the Rescue 42 safety features is the automatic retraction system. The core design of the Rescue 42 stabilization struts emphasizes mechanical safety, relying on features such as locking pins to secure the setup and ensure that it remains stable under load.

The two locking pins provide a dual mechanism for security, ensuring that the extensions are firmly locked in place and reducing the risk of accidental retraction during use. The orange marker for overextension serves as a visual indicator, helping users avoid extending the strut beyond safe limits. Additionally, the requirement for a pin to go through at least two extensions reinforces the structure's integrity and stability, which is particularly crucial in rescue operations.

In contrast, an automatic retraction system would introduce potential complexity and failure points, which could compromise the effectiveness and safety in emergency situations. Therefore, the absence of such a feature aligns with the overall focus on simplicity and reliability in the design of Rescue 42 equipment.
