What is the maximum depth limit for No-D dives?

• A. 100 FSW
• B. 130 FSW
• C. 150 FSW
• D. 160 FSW

Answer: (B)

The maximum depth limit for No-Decompression (No-D) dives is commonly accepted to be 130 feet of seawater (FSW). This depth is significant because it represents a threshold where divers can safely ascend to the surface without requiring staged decompression stops, provided they adhere to time limits outlined in diving tables or dive computers. At depths beyond 130 FSW, the risk of encountering nitrogen narcosis increases, and the complexities of managing decompression stress become more pronounced. The depth limit ensures that divers can optimize their dive planning and execution while minimizing the risks associated with pressure changes, nitrogen absorption, and the potential for decompression sickness. Therefore, 130 FSW is established as a standard limit within the diving community, making it the correct answer regarding maximum depths for No-D dives. This understanding helps divers make informed decisions during their planning and ensures safety throughout their diving activities.
