Why is it important to ditch an unconscious diver's equipment before lifting them?

Ditching an unconscious diver's equipment before attempting to lift them is crucial primarily for facilitating the movement of the diver. When a diver is unconscious, their body becomes heavier and more difficult to manage due to the added weight of their gear, which can include a tank, regulator, buoyancy control device, and other accessories. Removing these items not only reduces the total weight but also makes it easier for rescuers to maneuver the diver safely and effectively.

Additionally, lightening the load minimizes the risk of injury to both the rescuer and the diver. The equipment can create drag and make it challenging to lift or swim the diver to safety, particularly in situations where time is critical. Therefore, making the task easier through the removal of equipment enhances the chances of a successful rescue and improves response times in emergency situations.

While ensuring buoyancy, preventing equipment failure, and preparing for CPR are relevant considerations in a rescue scenario, the primary reason for ditching the diver's gear stems from the practical need to ease the physical demands of performing the rescue.
