Which of the following contributes to safe deep diving practices?

Following established procedures is crucial for ensuring safe deep diving practices. Established procedures are based on industry standards, best practices, and accumulated knowledge from experienced divers and organizations, which help mitigate risks associated with deep diving. These procedures cover various aspects of the dive, such as pre-dive planning, equipment checks, ascent rates, and emergency protocols. By adhering to these guidelines, divers can better manage the physical and psychological challenges of deep diving, ensuring they are adequately prepared for the dive environment and can respond effectively to any issues that arise.

In contrast, keeping dive plans secret can lead to dangerous situations if divers are unaware of each other's plans or potential risks. Diving in crowded areas increases the likelihood of accidents and miscommunications among divers. Skipping safety checks compromises equipment reliability and can lead to hazardous situations underwater, which is why following established procedures is fundamental to maintaining safety during deep dives.
