If using the NAUI RGBM dive tables, a minimum surface interval of ____ is required.

• A. 30 minutes
• B. 1 hour
• C. 15 minutes
• D. 45 minutes

Answer: (B)

The NAUI RGBM dive tables are designed to help divers manage their exposures to nitrogen and ensure safety during repetitive dives. A minimum surface interval is essential to allow the body to off-gas excess nitrogen absorbed during previous dives. The correct answer indicates that a minimum surface interval of 1 hour is required when using these tables. This duration is based on the understanding that longer surface intervals help to mitigate the risks of decompression sickness by allowing more time for nitrogen elimination from the body's tissues. The 1-hour interval provides a balance between safety and operational efficiency, ensuring that divers have adequate time to recuperate before undertaking subsequent dives. While shorter intervals may seem appealing for convenience, they do not allow sufficient time for proper nitrogen off-gassing, which is vital for maintaining a safe dive experience. Thus, adhering to the 1-hour minimum surface interval significantly contributes to diver safety.
