G'day 3top,
You might be interested in the table below? Although it was first produced in 1989 - shortly before the company in question went bankrupt. The company was the National Safety Council of australia - the NSCA.
They were a very large rescue orginasition in Australia who supplied fixed wing Pararescue, helicopter rescue, and hyperbaric retrivals.
The Parra-Jumpers - PJ's - of the Pararescue teams jumped with LAR-V diving equipment and had to train whilst on immediate standby with SCUBA as well as the LAR-V O2 set. The NSCA medical officers (trained in hyperbaric medcine) prepared the table so that 'on-shift' training could be conducted safely. The table was established using a mixture of Canadian and RN tables.
As an ex-RN Clearance Diver, and PJ, I found the company very proffesional. The fact that they employed diving doctors who were also trained as PJ's, and that the senior diving instructor was an ex RAN chief petty officer Clearance Diver, I believe, sums up the standard they operated to.
NSCA OPERATIONAL PROCEDURE FLYING AND DIVING
1. Allowable diving whilst maintaining immediate availability for operational flying.
a - LAR-V No Limit
b - Air diving 3meters 60minutes
6meters 30minutes
9meters 15minutes
2. Minimum required delay before flying or travelling to altitude after diving.
DIVING ACTIVITY UP TO 1000FT UP TO 3000FT
Up to 50% no deco
< 30m Nil Nil
Up to no deco limit
< 30m Nil 2Hrs
Repetitive dives
Deco diving
< 50m 2hrs 12Hrs
NOTE: Although we followed this table without incident - and indeed, that it extends to greater altitudes and depths, it was reasonably new. Due to the demise of the NSCA a long term study of it's effectivness wasn't undertaken, and should you ellect to use it I would suggest that you seek a current diving doctors opinion.
