How does the buddy system enhance safety during a dive?
✔✔The buddy system ensures that divers have mutual support in emergencies, allowing them to
assist each other in case of equipment failure or other problems.
What is the best practice for equalizing pressure during a descent?
✔✔Divers should equalize their ears frequently by gently blowing through their nose while
pinching their nostrils, known as the Valsalva maneuver.
Why is it important to ascend slowly after a dive?
✔✔Ascending slowly gives the body time to expel dissolved nitrogen safely, reducing the risk of
decompression sickness.
What should a diver do if they experience an out-of-air situation?
✔✔If a diver experiences an out-of-air situation, they should immediately signal their buddy and
switch to their alternate air source.

,How can a diver avoid nitrogen narcosis?
✔✔A diver can avoid nitrogen narcosis by staying within safe depth limits and ascending if they
feel any symptoms of confusion or disorientation.
What is the purpose of the regulator in scuba diving?
✔✔The regulator reduces the high-pressure air from the tank to a breathable level, providing the
diver with air to breathe during the dive.
How do you properly manage buoyancy at the surface?
✔✔At the surface, a diver should inflate their BCD slightly to remain afloat and avoid excessive
breathing effort.
What is the recommended method for diving in cold water to avoid hypothermia?
✔✔Diving in cold water requires wearing a dry suit or a thick wetsuit to insulate the body and
retain warmth.
Why should divers conduct a pre-dive safety check?
✔✔A pre-dive check ensures that all equipment is functioning correctly, that there are no issues
with the air supply, and that the diver’s gear is secure.

, What should a diver do if they feel discomfort in their ears during the descent?
✔✔The diver should stop descending, attempt to equalize by using the Valsalva maneuver, and
only continue if they feel comfortable.
What is the recommended rate of ascent after a dive?
✔✔The recommended rate of ascent is no faster than 30 feet per minute to allow the body to
safely eliminate dissolved nitrogen.
What is the importance of a dive computer?
✔✔A dive computer tracks a diver’s depth, time underwater, and ascent rate, ensuring they stay
within safe limits and reducing the risk of decompression sickness.
What are the primary steps in the buddy check system?
✔✔The buddy check includes verifying each other’s gear, ensuring the air supply is adequate,
checking the regulator and BCD, and confirming the dive plan.
