If a climber suddenly loses contact, what should the belayer do?

• A. Detach rope from climber.
• B. Call staff and wait for instructions.
• C. Let rope slack to speed descent.
• D. Maintain rope tension and brake to arrest the fall; communicate with the climber and assist as needed.

Answer: (D)

When a climber suddenly loses contact, the belayer’s priority is to arrest the fall and keep the climber safe. The correct action is to maintain rope tension and brake the rope to stop any further movement, while staying in control of the rope so no slack can feed out. This immediate restraint is what prevents a longer fall and gives you the time to assess and assist the climber.

While doing this, communicate with the climber to keep them calm and informed, and offer practical help, such as guiding them or preparing for a controlled recovery if appropriate. Detaching the rope would remove your safety grip, letting the climber fall further. Letting rope slack would allow more rope to pay out, increasing the fall distance. Waiting for staff slows down a critical safety moment and can leave the climber at risk.
