DAN question

[ARY]

Is it true that DAN covers your case only if your PPO2 did not exceed 1.4 during the dive? Regardless of the used mix purpose?

[aainslie]

How would they prove that? And why do they care about PO2?

Under their definitions, the only standards they refer to are those of the AAUS - and the AAUS allows a max PO2 of 1.6:

Pg 25 and

Pg 35

So I'd say the answer is no.

I have never heard or read that.

Thanks for the explanation!

The question arise after discussion over DAN Europe policies with east-european OW divers.

Reading from a bottom timer and knowing the mix (i suppose if i get into a chamber i wouldn't keep that in a secret to the staff) may suggest the PPO2...

Any way the rule is 1.6 and i feel happier now

Just make sure you're covered for diving and having an accident below 130'. That's where the DAN Master coverage comes in.

The AAUS refers to 1.6 but that's only one way to be on a "covered dive"

From page 25 of the member handbook:

Covered Dive means a recreational dive or
diving while a scuba instructor, divemaster,
underwater photographer, or while performing research under the auspices and following the diving safety guidelines of the American Academy of Underwater Scientists (AAUS). A dive begins upon entry into the water and ends upon exit from the water. A Covered Dive must begin while Insurance is in force.

Recreational here mean "not for pay" it is not as a surrogate for depth <130ft.

So 1.6 is only a limit when doing scientific dives not recreational dives.
