What Safety Measures Are in Place for Divers Visiting the USS Spiegel Grove

Diver Certification and Experience Requirements

  • Divers must have advanced level certification due to the wreck’s depths, which reach up to 135 feet. Regular diving experience and knowledge of wreck diving techniques are also essential.
  • Penetration into the wreck requires proper training and precautions, as exploring closed chambers or tunnels comes with additional risks. Divers should never enter regions where they cannot see daylight at the exit.

Dive Operator Safety Protocols

  • Dive operators and guides conduct thorough briefings covering entry, exit procedures, navigation, air management, and emergency protocols. Divers must pay close attention to these briefings and ask for clarification if needed.
  • Emergency procedures should be well understood and reviewed before each dive.Divers should always have the required safety equipment with them, such as dive computers, lights, and signaling devices.

Air Management and Decompression Procedures

  • The rule of thirds is followed for air management, with one-third of the air and time reserved for the return trip and emergencies. Divers must check air consumption and bottom time regularly to avoid decompression sickness.
  • Appropriate dive plans are crucial, especially when using a single AL80 cylinder with Nitrox. Diving to thirds of the gas supply is essential.

Wreck Penetration Safety

  • Hazards within the wreck, such as entanglement risks, demand cautious movement and good buoyancy control from divers. Divers must be aware of their surroundings to avoid accidents.
  • If penetrating the wreck, a wreck line and reel are necessary to guide the way out in reduced visibility, ensuring a safe and clear path back to the entry point.
