How should an out of gas emergency be communicated during touch contact?

In an out-of-gas emergency, clear and effective communication is crucial, especially during touch contact, as divers may be disoriented or in challenging situations. The correct approach involves using a series of rapid tugs at the contact point. This method serves two important functions: it provides an immediate signal to the buddy or diving partner that an emergency is occurring, and it ensures that the message is delivered quickly and effectively without overwhelming the receiving diver.

Rapid tugs create a distinct, noticeable communication pattern that can be recognized even in low visibility or turbulent conditions, which are common in cavern diving scenarios. This method also allows for immediate recognition and reaction, facilitating a swift response, which is vital in an out-of-gas situation where every second counts.

While other methods, such as a continuous tug or quick series of hand signals, might be useful in different contexts, they do not convey the urgency of an out-of-gas situation as effectively as rapid tugs do. Using buoyancy control devices is not a reliable means of communication in this emergency context, as it may not deliver a clear or immediate message to the buddy. Thus, the series of rapid tugs provides a straightforward and emergency-specific communication strategy that helps ensure diver safety.
