What should a diver do if they experience equipment failure underwater?

When a diver experiences equipment failure underwater, activating emergency protocols, communicating with their buddy, and following proper ascent procedures is essential for safety. This approach ensures that the situation is managed appropriately while prioritizing the diver's safety and the safety of their dive buddy.

Immediate communication with the buddy allows for assistance and coordination, which is crucial in emergency situations. The buddy can provide support, monitor the diver's condition, or assist with a controlled ascent if needed. Following proper ascent procedures helps prevent decompression sickness and ensures that the diver returns to the surface safely.

Engaging in an emergency protocol means that the diver is prepared for multiple scenarios and knows how to respond effectively, enhancing both their safety and that of their buddy. By not attempting to fix the issue mid-dive or ascending without notifying anyone, the diver mitigates risks associated with loss of control over the situation and unintended consequences from hasty decisions.
