Special Rules
  • Flying after diving wait 12 hours or for
    repetitive dives and/or multiple days wait 18
    hours (suggested)
  • Cold add 10 feet
  • 1000 altitude limit for RDP
  • Safety Stop always do a safety stop
  • A Safety Stop is REQUIRED for dives 100 plus or
    within three letter groups of NDL, or NDL
  • Ascend no faster than 60 feet per minute

31
Emergency Decompression
  • If a no decompression limit is exceeded by no
    more than 5 minutes, an 8 minute decompression
    stop at 15 feet is mandatory. Upon surfacing the
    diver must stay out of the water for at least 6
    hours.
  • If a no decompression limit is exceeded by more
    than 5 minutes a 15 foot decompression stop at 15
    feet is urged (air supply permitting). Upon
    surfacing the diver must remain out of the water
    for at least 24 hours before making another dive.
