In this episode of Into the Abyss: The Navy Diver's Guide, we examine the critical safety protocols for diving near active sonar systems. Learn about permissible exposure limits (PELs) based on sonar type, diver equipment (wetsuit, hooded, or helmeted), and distance from the source. We’ll break down how sound pressure levels (SPLs) and duty cycles impact diver safety, using official Navy worksheets and PEL tables. Plus, we’ll explore considerations for low-frequency and ultrasonic sonar, and the importance of coordination between dive teams and sonar operators to prevent hazardous exposure.

Description:

In this episode of Into the Abyss: The Navy Diver's Guide, we explore the administrative backbone of U.S. Navy diving operations. From maintaining dive logs and mishap reports (WESS) to submitting equipment failure analysis reports (FAR), this chapter of the Rev 7 Navy Diving Manual emphasizes the importance of meticulous documentation and reporting. Learn how thorough record-keeping helps analyze safety trends, prevent mishaps, and ensure operational readiness. We also cover HAZREPS, equipment security, and the reporting process for near-misses—critical steps in maintaining diver safety.

🎧 Tune in for a deep dive into the protocols that keep Navy divers safe and accountable.

In this episode of Into the Abyss: The Navy Diver's Guide, we break down the critical maintenance and operational procedures for U.S. Navy dive systems. Covering everything from Planned Maintenance Systems (PMS) to manufacturer manuals, we explore the rigorous standards for diver breathing gases—including air, oxygen, helium, and nitrogen. Learn about essential system components like compressors, high-pressure cylinders, gauges, and filtration systems, along with the approval process for operating and emergency procedures. Whether you're a diver or simply fascinated by underwater technology, this episode dives deep into the mechanics of staying safe below the surface.
