The U.S. Navy Diving Manual (Revision 7) is a comprehensive guide published by the U.S. Navy to outline procedures, standards, and best practices for diving operations. It serves as a critical reference for both military and commercial divers.

Diving physiology and safety

This chapter details how pressure changes affect the human body. It explains critical concepts such as gas exchange, nitrogen absorption, and the prevention of decompression sickness (DCS). The manual includes updated decompression tables and guidelines for various diving scenarios, ensuring divers can plan and execute safe ascents based on the depth and duration of their dives.

Diving equipment and systems

Another key component addresses diving equipment and systems, detailing the proper use, maintenance, and troubleshooting of diving gear. This includes surface-supplied diving systems, scuba gear, rebreathers, and specialized equipment for extreme environments. Proper equipment handling is emphasized as a vital aspect of operational safety.

Emergency procedures and medical guidance

The manual also delves into emergency procedures and medical guidance, equipping divers and supervisors with protocols to handle underwater incidents, from entanglements and equipment malfunctions to decompression emergencies. It includes instructions for administering first aid and performing hyperbaric treatments in cases of decompression illness or gas embolisms.

Unique diving environments and techniques

Unique diving environments and techniques, such as contaminated-water diving, cold-water diving, and high-altitude diving is covered in this section. These chapters provide tailored strategies and risk management practices to ensure safety in challenging conditions. Additionally, the manual outlines operational risk management principles to help teams identify and mitigate potential hazards during complex or high-risk dives.

Overall, the U.S. Navy Diving Manual Revision 7 is an essential resource that integrates decades of experience, rigorous research, and field-tested practices to ensure the safety and success of diving operations worldwide.
