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

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.
