Which of the following is a technique used for underwater emergency handling?

The technique involving assessing the situation, providing assistance, and communicating calmly is critical in underwater emergency handling. This approach ensures that divers remain composed and can evaluate what is happening, which is essential for both their safety and the safety of others involved.

By assessing the situation, divers can identify the specific issues that need to be addressed, whether it's a malfunction in gear, a buddy in distress, or environmental hazards. Providing assistance means being ready and able to help not just oneself, but also fellow divers who may need aid. Communicating calmly is vital, as clear instructions or signals can help facilitate a better understanding of the problem and the necessary steps to resolve it, reducing panic and confusion.

This method emphasizes the importance of maintaining control during a crisis rather than resorting to potentially dangerous behaviors, like ignoring the situation or making hasty movements, which can increase risks. It showcases a structured and responsible approach that is essential for effective emergency response while diving.
