&gt; About two weeks ago a diver died using the EDO 04, after he had purchased
&gt; the rebreather a week ago.
&gt;
&gt; The public prosecutor requested that I do an expertise of the unit of the
&gt; deseased. I did so in the presense of a police man.
&gt; Both units had the same failure point. This failure can kill a diver.
&gt;
&gt; Because not all users of the rebreather EDO 04 are known and cannot be
&gt; informed by the public prosecutor, this warning is done via the usual e-mail
&gt; lists.
&gt; If anybody knows a user of the rebreather EDO 04, he should give him this
&gt; notice as fast as possible.


Hallo Reinhard, List

auf http://www.thueringen.de/de/lka/aktu...74/uindex.html
findet man Bilder eines offensichtlich defekten Rückschlagventils in der
Ausatemlunge. Sieht aus wie ein uraltes Teil, dessen elastische
Komponente nicht formbeständig war, und damit undicht, oder verklebt.

Ich würde an dieser Stelle a) Redundanz, b) ein zuverlässigeres &nbsp;Teil
wählen, ZB ein Ventil mit Glimmerplättchen.

On http://www.thueringen.de/de/lka/aktu...74/uindex.html there is
shown what the police thinks to have been the cause of the acident. Pics
show a badly warped checkvalve, which may have been leaking, or stuck
closed.
