<Table 3> How to use No-decompression Dive Limit - Residual Nitrogen
Time Table? |
You can examine No-decompression Dive Limit and Residual Nitrogen Time
after Surface Interval Time in <Table 3> No-decompression Dive Limit
- Residual Nitrogen Time Table. |
You can examine the No-decompression Dive Limit for the second diving |
|
A diver of Residual Group E at the time of the first diving end plans the second diving of 15 m after 1 hour 30 minutes Surface Interval Time.What is the new no-decompression dive time? |
|
《The usage of Dive Table》
① Residual Group at the time of the first diving end is E in <Table
2> Surface Interval Time Table.
② You just trace aside from E and look for Surface Interval Time that is 1 hour 30 minutes or over 1 hour 30 minutes and closer to 1 hour 30 minutes.1 hour 30 minutes is between 1 hour and 2 hours.You just trace the line between 1 hour and 2 hours below.
③ You can look for the contact of the point traced 15 m aside and the point
traced the ② line in <Table 3> No-decompression Dive Limit - Residual
Nitrogen Time Table. |
|
|
a) Surface Interval Time. 1 hour 30 minutes is between 1 hour and 2 hours. b) No-decompression Dive Limit |
|
|
Correct answer: 51 minutes
A number of the top right corner is the new No-decompression Dive Limit at the contact.
A diver of Residual Group E at the time of the first diving end can plans the second diving of 51 minutes at 15 m after 1 hour 30 minutes Surface Interval Time. |
|
|
If Surface Interval Time is 1 hour, you should use the line between 30minutes and 1 hour for your safety. |
