Dive Theory & Safety Standards Flashcards

What is the primary purpose of the pre-dive safety check (BWRAF) in PADI training?

Answer: To verify equipment is functioning and both divers are ready

BWRAF (BCD, Weights, Releases, Air, Final check) is a systematic pre-dive safety check to ensure both divers' equipment is functioning properly and they are prepared for the dive.

What is the current PADI recommended maximum ascent rate for recreational scuba diving?

Answer: 18 meters per minute

PADI recommends a maximum ascent rate of 18 meters (60 feet) per minute, though many current guidelines suggest slowing to 9 meters (30 feet) per minute from the safety stop to the surface.

At what depth and for how long does PADI recommend performing a safety stop?

Answer: 5 meters for 3 minutes

PADI recommends a safety stop at 5 meters (15 feet) for 3 minutes at the end of every dive as a precautionary measure.

What condition caused by compressed air at depth may impair a diver's judgment?

Answer: Nitrogen narcosis

Nitrogen narcosis is an altered state of consciousness caused by elevated partial pressures of nitrogen at depth, often described as an 'underwater intoxication.'

What is a 'square profile' dive and why does it consume the NDL faster than a multilevel dive?

Answer: A dive where the diver stays at maximum depth the entire time, spending more time at maximum nitrogen absorption

A square profile means spending the entire dive at maximum depth, which consumes the no-decompression limit faster than a multilevel profile that spends most time at shallower depths.

What is the significance of the PADI certification card (C-card) in recreational diving?

Answer: It proves a diver has met training requirements and allows participation in diving activities worldwide

A PADI C-card is internationally recognized proof that a diver has completed the required training for a specific certification level.
