Section 1: Dive Theory and Safety
What is the most important rule in scuba diving?

What should you do if you begin to feel a squeeze in your ears during descent?

What can happen if you ascend too quickly?
A: You risk decompression sickness (DCS).
What is the best way to prevent nitrogen narcosis?
A: Dive within the recreational depth limits.
If your mask floods underwater, what should you do?
A: Tilt your head back, press on the top, and exhale through your nose.
Section 2: Dive Equipment
What is the purpose of a buoyancy control device (BCD)?
A: To help control your buoyancy during the dive.
Which part of your gear shows how much air you have left?
A: Submersible pressure gauge (SPG).
, How should you rinse your gear after a dive?

If you and your buddy become separated, what should you do?
A: Search for no more than 1 minute, then surface and reunite.
Why do you make a safety stop at 5 meters (15 feet)?

What does a dive table or dive computer help you monitor?
A: No-decompression limits and nitrogen absorption.
When should you avoid flying after diving?
A: At least 12 hours after one dive and 18 hours after multiple dives or a dive
requiring decompression stops.
