Andrea Doria Death

[Jamie_r]

This is a very sad story to read in detail. Accidnets happen to anyone at anytime I forget this too often.


Im not sure what a lift bag is used for, i had first thought this was to float somthing salvaged from the bottom, if so, why hold onto anything attached to that bag shooting to the surface? can someone inform me why this is used?

It is typical, with a long decompression obligation ahead, to send a bag to the surface attached to a reel which the diver continues to hold. It serves several purposes, letting the surface crew know that everything is ok (in some locales a different color/style of bag is used to let the crew know everything is not ok). It also provides a convenient reference for the decompressing diver, who somewhat bored, has something to hang on to. The skill/difficulty is shooting it without riding it up. It is practiced a lot during technical training (I know, I have been undergoing this lately). Maintaining depth is hugely important to decompression dives and the divers who make them. A surface excursion can bend and possibly kill you.
