What is the best technique for preventing air consumption fatigue during a dive?
✔✔Conserving energy, maintaining neutral buoyancy, and breathing slowly can help reduce air
consumption and prevent fatigue.
How should a diver react if they lose contact with their dive buddy?
✔✔The diver should stop, remain calm, and make a slow, deliberate search for their buddy,
using hand signals or light signals if needed.
What does the term "buddy check" mean before a dive?
✔✔A buddy check involves reviewing each other's gear and confirming that everything is
functioning properly before entering the water.
Why is it important to monitor your air gauge frequently during a dive?
✔✔Regularly checking the air gauge ensures you don’t run low on air unexpectedly, allowing
for a safe and controlled ascent if needed.

,What is the primary function of a regulator during a dive?
✔✔The regulator delivers air from the tank to the diver, adjusting the pressure to make breathing
easier at different depths.
Why is slow ascent vital for a diver’s safety?
✔✔A slow ascent allows nitrogen to safely leave the body, preventing decompression sickness.
What does "neutral buoyancy" mean, and why is it important?
✔✔Neutral buoyancy means that a diver neither sinks nor rises, which helps conserve energy
and allows the diver to move effortlessly through the water.
What is the role of the safety stop in diving?
✔✔A safety stop, typically at 15 feet for 3-5 minutes, allows nitrogen to safely dissipate from
the body, reducing the risk of decompression sickness.
What should a diver do if they experience a deep cut or injury underwater?
✔✔The diver should signal their buddy, stop the dive, and assess the injury while slowly
ascending to a safer environment, such as the surface or a boat.

, How can divers prevent panic if they lose their mask during a dive?
✔✔Divers should stay calm, clear their nose to avoid discomfort, and use the buddy system to
either retrieve the mask or safely ascend.
What should a diver do if their buoyancy control device (BCD) malfunctions?
✔✔If a BCD malfunctions, the diver should use the oral inflator as a backup to control buoyancy
and signal their buddy for assistance.
What are the dangers of a rapid ascent from a deep dive?
✔✔A rapid ascent can cause nitrogen bubbles to form in the bloodstream, leading to
decompression sickness, which can be life-threatening.
What is the purpose of the dive tables or dive computer?
✔✔Dive tables or dive computers help track time and depth to ensure a diver ascends safely and
avoids decompression sickness.
What does the term "descent line" mean in the context of scuba diving?
✔✔A descent line is a rope or marked path used by divers to safely descend and stay aligned
with the planned dive depth.
