PADI Enriched Air Diver exam with
|\ |\ |\ |\ |\ |\
answers
What is "enriched air"? - CORRECT ANSWERS ✔✔Enriched air is
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
any nitrogen/oxygen gas blend with more than 21% oxygen.
|\ |\ |\ |\ |\ |\ |\ |\
What is the primary benefit of using enriched air? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔It exposes you to less nitrogen than when you dive
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
with air. |\
How does using enriched air affect no stop limits? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔It allows longer no stop limits because you are
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
absorbing less oxygen. |\ |\
Why is it too simplistic to say enriched air is safer than air when
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
diving will within air no decompression limits? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Higher oxygen levels create a potential hazard that
|\ |\ |\ |\ |\ |\ |\ |\
hardly exists in air diving within recreational limits.
|\ |\ |\ |\ |\ |\ |\ |\
How does using enriched air affect narcosis when diving? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔The current thinking is the narcosis
|\ |\ |\ |\ |\ |\ |\ |\
potential is the same. |\ |\ |\
What are three advantages of using an enriched air dive
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
computer for enriched air diving? - CORRECT ANSWERS ✔✔1)
|\ |\ |\ |\ |\ |\ |\ |\ |\
Computers combine enriched air with multilevel diving for the
|\ |\ |\ |\ |\ |\ |\ |\ |\
most no stop time possible.
|\ |\ |\ |\
, 2) Most models will or can be set to alert you if you accidentally
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
exceed the maximum depth for your gas blend.
|\ |\ |\ |\ |\ |\ |\
3) Dive computers simplify diving planning and execution by
|\ |\ |\ |\ |\ |\ |\ |\ |\
calculating both your oxygen exposure and your allowable no |\ |\ |\ |\ |\ |\ |\ |\ |\
stop time, and warn you if you near the limits of either.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
What is the primary concern regarding enriched air and scuba
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
equipment? - CORRECT ANSWERS ✔✔High oxygen content. |\ |\ |\ |\ |\ |\
What are the requirements and recommendations for scuba
|\ |\ |\ |\ |\ |\ |\ |\
equipment (other than cylinders) used with enriched air with up
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
to 40 percent oxygen? - CORRECT ANSWERS ✔✔1) Regulators,
|\ |\ |\ |\ |\ |\ |\ |\ |\
BCDs, SPGs, and alternate air sources may be used without
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
modification.
2) Follow manufacturers recommendations.
|\ |\ |\ |\
3) Use oxygen compatible lubricants, o-rings, and other materials
|\ |\ |\ |\ |\ |\ |\ |\
as appropriate during service.
|\ |\ |\ |\
4) Have your regulator serviced annually, preferably by a
|\ |\ |\ |\ |\ |\ |\ |\ |\
technician qualified to work on enriched air equipment. Have it
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
inspected or recleaned by a qualified technician if you
|\ |\ |\ |\ |\ |\ |\ |\ |\
accidentally expose it to anything other than water. |\ |\ |\ |\ |\ |\ |\
Why does enriched air diving require a dedicated cylinder? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔1) It is important that no one accidentally
|\ |\ |\ |\ |\ |\ |\ |\ |\
confuse an enriched air cylinder for one of normal air.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
2) If partial pressure blending with oxygen will be used, the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
cylinder must meet oxygen service standards.
