What is the single depth limit for 25 fsw?

Explanation:
At 25 fsw, the maximum time you can stay at that depth without needing decompression stops is determined by the no-decompression limit. The standard tables assign a limit of 240 minutes (4 hours) for this depth. This means you can remain at 25 fsw for up to four hours and still ascend without mandatory decompression procedures. If you exceed that bottom time, you’d need to perform decompression stops to safely off-gas nitrogen on the way up. So the best answer is 240 minutes because it reflects the long no-decompression allowance at this shallow depth. The other times are shorter than the official no-decompression limit for 25 fsw.
