Question: when diving with enriched air nitro, for a given depth you should expect narcosis to
be _______________ compared to diving with air. - CORRECT ANSWER✔✔the same as




Question: True or false: it is to 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 and recreational air diving. - CORRECT ANSWER✔✔True




Question: Advantaged of using a dive computer with enriched air nitro include that.... -
CORRECT ANSWER✔✔it adds multilevel diving advantages for the longest no stop dive time,
most models will warn you if you exceed the maximum depth for your gas blend, and simplifies
dive planning




what is the primary benefit of diving with enriched air? - CORRECT ANSWER✔✔it exposes you
to less nitrogen and let's you dive longer




Question: What is enriched air? - CORRECT ANSWER✔✔Enriched air is any nitrogen/oxygen gas
blend with more than 21% oxygen.

Question: Enriched air ____________ the no stop limits compared to air - CORRECT
ANSWER✔✔Extends




Question: The general recommendation for scuba equipment (other than your cylinder) used
with enriched air is... - CORRECT ANSWER✔✔everything can be used normally just as it is with
air up unless using a blend of more than 40% O2




Question: True or false: Some SCUBA manufacturers have special recommendations or
requirements that you should follow when using their equipment with enriched air nitrox. -
CORRECT ANSWER✔✔True




Question: The primary concern regarding enriched air in scuba equipment is - CORRECT
ANSWER✔✔Contact with high oxygen content may cause fire, explosion, or deterioration




Question: Based on broadly accepted international dive community practices, enriched air
cylinders, should have the following: - CORRECT ANSWER✔✔Yellow cylinders should have a
green band at the shoulder with enriched air or similar designation, the cylinder should have a
standard visual inspection sticker, the cylinder should have a contents sticker, and the cylinder
should have a sticker to indicate whether it's oxygen service rated.

Question: Nitro requires a dedicated cylinder because... - CORRECT ANSWER✔✔it's important
no one accidentally confuse it with an air cylinder - it can be hazardous to unknowingly dive
with enriched air, and it can be hazardous to blend enriched air in a conventional air cylinder




Question: in what areas would you expect enriched air cylinder to have a green or green/yellow
band on shoulder with "nitro" or similar written on it? - CORRECT ANSWER✔✔in most areas
internationally, but some regions use different markings




Question: if an enriched air cylinder or oxygen service rated equipment is used with standard
compressed air, you.... - CORRECT ANSWER✔✔should have it serviced by an enriched air
qualified professional




Question: In looking for qualified enriched air service, look for________ - CORRECT
ANSWER✔✔Gas quality verification, proper enriched air procedures, and blender certification
such as Tex gas blender.




Question: The two most common blends of enriched air are: - CORRECT ANSWER✔✔EANx32
and EANx36




Question: what is Oxygen partial pressure (PO2)? - CORRECT ANSWER✔✔It is used to measure
the concentration of oxygen a diver is exposed to, expresses the part of a gas pressure exerted
by the oxygen in the gas, is usually expressed in atmospheres or bar, and will vary at a given
depth depending upon the oxygen percent.

Question: Exposure to increased oxygen partial pressure can make your allowable dive time
______________ - CORRECT ANSWER✔✔Shorter. Diving with enriched air, usually gives you
longer dive times, due to reduce nitrogen, but at times oxygen exposure can limit your dive
time.




Question: The maximum and contingency oxygen partial pressure limit is _______ ata/bar -
CORRECT ANSWER✔✔1.4




Question: For the most common blends of enriched air, what are the maximum depths in get it
before exceeding 1.4 ata? - CORRECT ANSWER✔✔32% - 111 ft

36% - 95 ft




Question: True or False: the primary hazard of exceeding oxygen exposure limits is drowning
due to central nervous system (CNS) oxygen toxicity. - CORRECT ANSWER✔✔True




Question: True or False: Warning signs and symptoms may or may not precede an oxygen
convulsion. - CORRECT ANSWER✔✔True




Question: Signs and symptoms that may proceed a convulsion due to oxygen toxicity include -
CORRECT ANSWER✔✔VENTID - Visual disturbances, ear ringing, nausea, twitching, irritability,
