What is the first action to take when you notice a belay device is not functioning correctly?

• A. Pause, inspect, adjust or replace the device, and retreat if necessary.
• B. Continue belaying at a reduced speed while monitoring the device.
• C. Ignore minor heat and proceed.
• D. Reseat the rope and test again after a long delay.

Answer: (A)

When a belay device isn’t functioning correctly, the priority is to stop and take control of the situation immediately. A suspect device can fail suddenly, turning a controlled belay into a dangerous drop, so you don’t keep going with the issue unresolved.

Pause and maintain a firm brake grip on the rope, then inspect what’s wrong. Look for obvious problems like a jam, unusual heat, wear or damage to the device, incorrect threading or orientation, and any issues with the carabiner or rope. If you find a fault, fix it if possible (or replace the device) and only proceed if you’re confident the gear is safe and functioning. If you can’t resolve the issue on the spot, retreat to safety—lower the climber if that’s feasible and return to a solid, safe belay setup or remove the faulty device from service.

Continuing with reduced speed or testing after a long delay can mask the problem or lead to a sudden failure, so the safe course is to address the problem now and only resume belaying once the device is functioning reliably.
