Brett Gilliam called me this afternoon. He does not have e-mail and the
Uwatec Office is moving to Maine next week, but I had fax'd him my
concerns.

He states emphatically that the limit of 1.6 ATA is the standard and that
*no one* has ever had a problem at lower pPO2s who has not also exceeded
the NOAA O2 partial pressure limits. He further states that if PADI wants
to be more conservative, they can be so, but that his opinion is shared by
DAN, Dick Rutkowski and of course, ITD and IANTD

He is interested to hear from knowledgeable divers on this. I have
promised to pass on any comments that I receive. He denies that the US
Navy Divers handbook is referring to brief exposure O2 toxicity, but CNS
toxicity when the NOAA pPO2 CNS clock limits have been exceeded.

So has anyone any data? Has anyone counter or agreeing opinions?
