What harness-to-rope connection risk you must mitigate?

• A. Potential for harness attachment to fail or come undone; ensure proper tie-in, backup, and secure carabiner connections.
• B. Risk of rope fray at the anchor.
• C. Probability of pulley jam.
• D. Chance of patient movement.

Answer: (A)

The main idea here is the reliability of the harness-to-rope interface—the way the rope is connected to the rescuer’s harness. If that connection can fail or come undone, the person attached to the rope may detach under load, which is a major fall risk and undermines the whole rescue system. The best approach is to ensure a proper tie-in to the harness, use a backup or redundant connection, and keep carabiner connections secure. This means using a correct tying method or attachment that suits the harness, locking carabiners oriented to avoid gate opening or cross-loading, and establishing a secondary connection so that a single failure doesn’t result in a loss of control or fall. Regularly checking the setup before loading and after any movement helps catch issues early and keeps the system trustworthy.

Rope fray at the anchor, pulley jams, and patient movement are important considerations in rope rescue, but they don’t directly address the immediate risk of the harness detaching from the rope. The harness-to-rope failure risk is the most direct threat to the integrity of the rescue system, hence the emphasis on a solid tie-in, backup, and secure connections.
