The overhand knot is not suitable for which two purposes?

• A. Climbing Anchors and Rescue Operations
• B. Decorative Knots and Signaling
• C. Load Bearing and Life Safety
• D. General Rope Handling

Answer: (C)

Not all knots are safe for every job; some are fine for light, everyday handling, while others must meet safety and reliability standards. The overhand knot is a quick, simple stopper knot that's great for ending a rope and preventing fraying. But when it’s loaded, it tends to jam and can be very hard to untie, which makes it unreliable for situations where the rope must bear weight or be retrievable after loading. In climbing anchors and rescue operations, you want knots that stay controllable under load and can be untied after use, so the overhand isn’t suitable there. For decorative knots or signaling, and for general rope handling where heavy loads aren’t involved, the overhand can still be used. Therefore, the two unsuitable purposes are load bearing and life safety.
