These questions and answers were taken from PADI Diving Knowledge Workbook, International PADI, 1996.

Mrs Scuba 101 filling in :o

OK here is the scoop,

B. The diver has exceeded the no-decompression limit for 30 meters/100 feet. However, the overstay has been for less than 5 minutes. Had he overstayed the NDL for more than five minutes, response A would have been correct. Incidentally, dives should never be planned to the full limit of the table, and this scenario is one reason why.
