ENRICHED AIR NITROX TEST BANK
COMPLETE QUESTIONS AND SOLUTIONS
ALREADY GRADED A+
●● according to dalton's law the pressure exerted by each gas in a
mixture will add up to the total pressure of the gas
Answer: true
●● a diver using EAN33 at a depth of 21msw (70fsw) has a 1.025 partial
pressure of oxygen
Answer: true
21/10=2.1
2.1+1=3.1
3.1*.33=1.025
OR
70/33=2.1
2.1+1=3.1
3.1*.33=1.025
●● it is your responsibility to know what breathing mixture is in your
cylinder and to maintain your equipment in a safe manner for use with
nitrox
Answer: true
, ●● all RGBM divers should have a 3 min safety stop at 5 msw
Answer: true
●● the 40% rule is based on published peer reviewed research and is a
definitive industry standard
Answer: false
●● air is mostly comprised of oxygen and other miscellaneous gases
with the least abundant gas being Nitrogen
Answer: false
●● the ODIGTML order was originally determined to acount for the
most potentially serious physiological concerns facing dives
Answer: true
●● EAN41 is the best mix at a depth of 24.3 (80fsw) with PPO2 of 1.4
Answer: false
math = 0.408 but cant round down
●● any equipment that is going to be exposed to a gas that contains
greater than 40% oxygen must be oxygen cleaned and free of
hydrocarbons
