What is the importance of equalizing pressure during a dive?
✔✔Equalizing pressure prevents discomfort or injury to the eardrums and sinuses due to changes
in ambient pressure as a diver descends or ascends.
What should a diver do if they feel disoriented underwater?
✔✔The diver should remain calm, stop moving, and assess their surroundings. They can signal
their buddy or use a dive light to find their orientation.
How does a dive computer assist in planning a dive?
✔✔A dive computer tracks depth, time, and ascent rates, providing real-time data to help prevent
decompression sickness and ensuring a safe dive profile.
What is the correct procedure for handling a runaway ascent?
✔✔If a runaway ascent occurs, the diver should try to slow the ascent by exhaling continuously,
and immediately ascend slowly to the nearest safe stop or the surface if necessary.

,Why is it important to monitor your air supply during a dive?
✔✔Monitoring air ensures that a diver has enough to safely complete the dive and ascend,
preventing emergencies like running out of air underwater.
What is the role of the safety stop during the ascent?
✔✔A safety stop, typically at 15 feet for 3-5 minutes, allows nitrogen to safely off-gas from the
body and reduces the risk of decompression sickness.
What should a diver do if their regulator free-flows underwater?
✔✔If a regulator free-flows, the diver should switch to the alternate air source, stop the flow by
adjusting the regulator, and signal the buddy for assistance.
Why is it necessary to dive with a buddy?
✔✔Diving with a buddy provides safety, as the buddy can assist in emergencies, perform
rescues, and help prevent accidents during the dive.
What is the best way to avoid nitrogen narcosis?
✔✔To avoid nitrogen narcosis, divers should limit their depth, use appropriate dive tables or
computers, and ascend if they experience symptoms like confusion or disorientation.

, What actions should a diver take if they experience an air embolism?
✔✔If an air embolism is suspected, the diver should immediately stop the ascent, perform an
emergency ascent, and seek medical attention as soon as possible.
How can a diver prevent damage to their equipment during a dive?
✔✔Divers should inspect their gear before each dive, avoid dragging equipment on the seabed,
and store gear properly between dives to avoid wear and tear.
Why is it essential to wear a wetsuit or drysuit?
✔✔Wetsuits and drysuits help maintain body temperature, preventing hypothermia in colder
waters by providing thermal protection.
What is the function of the mask during a dive?
✔✔The mask allows the diver to see clearly underwater by creating an air pocket in front of the
eyes, protecting them from the surrounding water.
What should a diver do if they run low on air during a dive?
