PADI EANX WRITTEN EXAM.
"Enriched Air" is - CORRECT ANSWER a mixture of oxygen and nitrogen with more than 21% oxygen
The primary benefit of using enriched air is that it lets you - CORRECT ANSWER dive longer
Enriched air_________ the no stop limits compared to air - CORRECT ANSWER extends
It is too simplistic to say enriched air is safer than air when well within air no stop limits because
enriched air creates an oxygen hazard and the DCI rate is already very low in recreational air diving -
CORRECT ANSWER True
Using enriched air ___________ narcosis when diving - CORRECT ANSWER has no effect on
Advantages of using an enriched air dive computer for enriched air diving include (check all that apply): -
CORRECT ANSWER providing maximum no stop time by combining EANx and multilevel diving
the ability to warn you if you exceed your maximum depth.
simplifying dive planning
The primary concern regarding enriched air and scuba equipment is: - CORRECT ANSWER that contact
with high oxygen content may cause fire, explosion or deterioration
When using enriched air with up to 40% oxygen (check all that apply): - CORRECT ANSWER Generally,
you may use standard scuba equipment(except cylinder).
Use of oxygen compatible lubricants is generally recommended.
Follow all manufacturer recommendations regarding using their equipment with enriched air.
Enriched air requires a dedicated cylinder because (check all that apply): - CORRECT ANSWER it can be
hazardous to unknowingly dive with enriched air.
it can be hazardous to blend enriched air in a conventional air cylinder
