It may be an extreme case, but it's one we can all
learn from. Back in August 2012, Lex Warner was
on the deck of the MV Jean Elaine, preparing to dive
a wreck off Cape Wrath in northwest Scotland. A
50-year-old experienced recreational and technical
diver, Warner had received his trimix certification
three years prior and was a member of the "Dark
Star," an informal but invitation-only group of experienced
technical divers.
Ready to dive and seriously loaded with a trimix
rebreather, two open-circuit bailout tanks, and the
other paraphernalia required for such a deep, dark
dive, Warner slipped and fell on the heaving deck
of MV Jean Elaine. He was so loaded down, he could
not get himself up. Skipper Andy Cuthbertson and
deckhand Allan Stanger helped him to his feet. With
mouthpiece in, Warner nodded he was OK. Minutes
later, he was descending onto the wreck far below.
Other divers saw Warner at both 130 feet and 230
feet, and he appeared to be swimming well, but at 290
feet deep and only 10 minutes since his deck fall, his
dive computer revealed, upon later examination, that
he started heading back on the long route to the surface.
His breathing appeared normal, but by the time he reached 66 feet, he was struggling to breathe and
control his buoyancy.
Other divers tried to help Warner, but by this time,
he was without any breathing equipment in his mouth,
and eventually they had no alternative but to send him
shooting to the surface by means of an emergency lifting
bag. Attempts to resuscitate Warner at the surface
failed, and he was declared dead at the hospital.
A post-mortem examination revealed he had
suffered internal injuries inconsistent with diving,
which the medical examiner attributed to his fall on
the boat. Several months later, the Marine Accident
Investigation Branch, alerted by Warner's wife,
reviewed the findings and decided he died from
decompression sickness due to ascending and missing
decompression requirements. However, both sets of
doctors agreed that Warner's internal injuries were a
medical emergency in their own right.
What can be learned from this? If you are not 100
percent fit and well before diving, don't press on regardless,
thinking it will be better underwater. It won't. And
that doesn't matter whether you are doing an extreme
technical dive or a simple one down to 60 feet.
