PADI ENRICHED AIR DIVER TEST QUESTIONS AND CORRECT ANSWERS
LATEST UPDATED
"Enriched air": what is it? The response Any mixture of nitrogen and oxygen
that contains more than 21% oxygen is considered enriched air.
What is the main advantage of enriched air use? The response Compared to
diving with air, it exposes you to less nitrogen.
What is the impact of enriched air on no stop limits? The response Because you
are taking in less oxygen, it permits longer no stop limitations.
When diving in air with no decompression constraints, why is it oversimplified
to claim that enriched air is safer than air? The response Elevated oxygen
concentrations pose a risk that is rarely present when air diving within
recreational bounds.
What is the impact of enriched air on narcosis during diving? The response The
narcosis potential is now thought to be the same.
What are the three benefits of enriched air diving with an enriched air dive
computer? The response 1) To minimize stop time, computers integrate
multilevel diving and enhanced air.
2) If you unintentionally go deeper than the maximum depth for your gas blend,
the majority of models will or can be configured to notify you.
3) By determining your oxygen exposure and your permitted no stop time, as
well as alerting you if you approach either limit, dive computers make planning
and execution easier.
What is the main issue with scuba diving gear and enriched air? The response
high level of oxygen.
What specifications and guidelines apply to dive gear (apart from cylinders)
, used with enriched air that contains up to 40% oxygen? The response 1)
Alternative air sources, BCDs, SPGs, and regulators can be utilized unmodified.
2) Adhere to the manufacturer's instructions.
3) When performing maintenance, use oxygen-compatible lubricants, o-rings,
and other materials as needed.
4) Have a technician certified to operate on enriched air equipment service your
regulator once a year. If you unintentionally expose it to anything other than
water, have a trained technician examine or clean it.
Why is a specialized cylinder needed for enriched air diving? ANSWER 1) It's
crucial that no one unintentionally mistakes an enhanced air cylinder for a
regular air cylinder.
2) The cylinder must adhere to oxygen service standards if partial pressure
blending with oxygen will be utilized.
Which tags, labels, and color labeling are appropriate for an enriched air
cylinder? The response 1) A 4-inch green band with white or yellow text should
be attached to yellow cylinders.
2) A 6-inch band with 1 inch of yellow on the top and bottom, green in the
center, and yellow or white text is appropriate for non-yellow cylinders.
3) A dated visual inspection sticker ought to be present.
4) A sticker indicating whether it satisfies oxygen service criteria ought to be
present.
5) The oxygen content, the fill date, the maximum depth for the blend, and the
name of the person who verified the blender's analysis of the oxygen content
should all be listed on a contents sticker or permanent tag.
What are the two main issues that arise when enriched air cylinders are filled,
and how can they be prevented? ANSWER 1: The risk of fire or explosion.
2) The blend's oxygen percentage.
Fill your enriched air cylinders only with trustworthy, certified enriched air
blenders.
Why should enriched air cylinders only be filled by certified, reliable enriched
air blenders? - ANSWER They are equipped and trained to handle the two main
issues related to enriched air cylinders.
What possible risks result from using incorrect enriched air filling techniques?
The response fire or explosion and receiving a different oxygen mixture than
what you requested.
