When planning a multi-level dive, which sequence of depth profiles is safest to follow?
Answer: Deepest portion first, then progressively shallower
PADI recommends the 'reverse profile' warning: you should dive deepest first and ascend progressively shallower to allow nitrogen off-gassing and reduce DCS risk.
What is the primary purpose of a pre-dive safety check (BWRAF)?
Answer: To verify equipment is correctly configured and functioning before entering the water
BWRAF (BCD, Weights, Releases, Air, Final OK) ensures all equipment is properly set up and working before the dive begins.
A dive group is planning a shore dive at an unfamiliar site. What is the FIRST step in site assessment?
Answer: Check local dive charts, guidebooks, or consult local dive operators
Researching the site through charts, local knowledge, and dive operator briefings is the essential first step before entering an unfamiliar dive site.
Which factor most directly determines the maximum allowable bottom time on a repetitive dive?
Answer: Residual nitrogen from previous dives
Residual nitrogen carried from previous dives reduces the allowable bottom time on subsequent dives to avoid exceeding no-decompression limits.
What does the term 'surface interval' refer to in dive planning?
Answer: The rest period between dives that allows nitrogen to off-gas
A surface interval is the time spent on the surface between dives, during which the body off-gases residual nitrogen, affecting repetitive dive limits.
During dive planning, which condition would most likely cause a dive leader to postpone a planned deep dive?
Answer: Surge and surge-driven currents exceeding diver ability
Strong surge and currents beyond diver competency create significant safety risks, making postponement the responsible decision.
When using the PADI Recreational Dive Planner (RDP), what does the 'pressure group' letter indicate?
Answer: The amount of residual nitrogen in a diver's tissues
The pressure group letter on the RDP represents the amount of residual nitrogen remaining in a diver's tissues after a dive.
