Before applying full load to a rigging system, what should be done?

• A. Dress the knot and test with controlled loading before full load.
• B. Assume it's fine if the knot looks correct.
• C. Apply full load immediately to test strength.
• D. Remove all knots and start over.

Answer: (A)

Before applying full load, make sure the knot is properly dressed and then test with controlled loading. Dressing the knot means arranging all strands so the knot sits neatly, with no twists, misplacements, or crossed lines, and ensuring the locking parts are snug and the load path is clean. When you apply a small, controlled load first, you’re checking that the knot and rope behave as expected under tension—watching for any slipping, loosening, or shifts in the strands. This step catches mistakes or setup issues early, reducing the risk of sudden failure when the system is loaded to its full working force. It also helps confirm that the knot and rigging will hold up under the actual dynamic conditions you’ll encounter. Relying on appearance alone isn’t safe because a knot can look correct yet still be mis-tied or misoriented, which can lead to slip or capsize under load. Jumping to full load without a controlled test ignores warning signs and can cause catastrophic failure. Starting from scratch by removing knots and restarting is unnecessary and wastes critical time, and it removes already-verified secure configurations in routine operations.
