What is the single depth limit for 40 fsw?

• A. 15 minutes
• B. 10 minutes
• C. 25 minutes
• D. 80 minutes

Answer: (B)

Single depth limit is the maximum bottom time at a given depth that allows you to ascend to the surface without performing decompression stops, using the dive tables used in this course. At 40 fsw, the single depth limit is 10 minutes. This provides a simple, conservative rule for planning a shallow dive: stay within 10 minutes at that depth to avoid decompression obligations. If you need more time at 40 fsw, you’d have to plan decompression stops on the ascent or adjust the dive profile to stay within safe limits per the tables.
