The most essential part of emergency procedures involves emergency assistance and evacuation plans. The evacuation plan is critical in ensuring the safety of divers in a cavern environment, as it outlines the steps to take in the event of an emergency. This plan needs to be clear and well-practiced, as divers may need to leave the water quickly and efficiently to reach a safe area. A proper evacuation plan reduces confusion and increases the likelihood of a safe outcome during an emergency situation.

Other elements, such as recovery, communication, and rescue, are also important in emergency protocols but focus more specifically on processes to follow after an incident has occurred rather than the immediate response to get divers out of danger. The priority in emergencies is to evacuate individuals from the hazardous environment quickly and safely. Thus, having a robust evacuation plan plays a vital role in overall emergency preparedness within cavern diving.
