Which of the following is a strategy for safe dive entry and exit?

Using the buddy system is a fundamental strategy for ensuring safe dive entry and exit. This approach involves diving with a partner who can assist in case of an emergency, enhancing safety through mutual support and awareness. The buddy can monitor each other's well-being, provide assistance during any complications, and help with navigation, making the entire diving experience safer.

In contrast, diving at night presents unique challenges and risks that require additional skills and precautions, making it less favorable as a general strategy for safe entry and exit. Similarly, descending rapidly could lead to issues such as barotrauma or nitrogen narcosis, which could be dangerous, especially if a diver encounters problems during the descent. Ignoring environmental factors, such as currents, weather, or water conditions, can significantly increase risks and jeopardize safety during diving activities. Thus, utilizing the buddy system stands out as a proactive safety measure for divers.
