Question 56 ONC05 - Master or Mate of LT 200 GRT

The Correct Answer is C **Explanation for Correctness (Option C):** Option C describes the standard and safest method for a conscious survivor to properly don a SAR (Search and Rescue) helicopter rescue sling (often a type of single-loop sling like the Mk 10 or similar): * **Loop Placement (Behind the Back and Under the Arms):** This configuration ensures the survivor is supported by their torso, placing the load high on the chest and back. This prevents the survivor from slipping out and maintains an upright, safe lifting posture. * **Facing the Winch Hook (or Aircraft/Winch Operator):** Facing the direction of the hoist line and aircraft allows the survivor to maintain visual contact with the winch operator or hoist equipment. This helps with balance, stability, and allows the survivor to anticipate the tension and movement of the line. **Explanation for Incorrect Options:** * **A) The person sits in the sling with their hands clasped across the chest while facing the winch hook:** While facing the hook is correct, a rescue sling is not designed to be sat in like a harness or basket. Attempting to sit in a single-loop sling would cause the person to slip through or be lifted uncomfortably and dangerously by the groin area. * **B) The loop of the sling passes across the chest and under the arms while facing away from the winch hook:** Placing the loop across the chest (in front) and under the arms is incorrect. This placement creates a high risk of the loop riding up dangerously high on the throat or constricting breathing when tension is applied. Furthermore, facing away from the winch hook removes the visual reference needed for stability and coordination during the hoist. * **D) The person steps onto the sling grasping the hoist line for support while facing away from the winch hook:** This option describes a completely incorrect and highly dangerous procedure. A survivor must never step onto the sling, as it provides no stable platform, and grasping the moving hoist line is extremely dangerous due to the risk of line entanglement, burns, or being pulled off balance. Facing away is also incorrect.
