Fwd: RE: Quicksand



Ooops, forgot to change this to the list, not Darryl. Line breaks will
probably be bowdlerised.

    I was talking a few years ago with a fireman from Morcambe
(Lancashire, England) at a caver's party of some sort. One of his
irregular rescues was of people who'd got mired in the sands and muds
of Morcambe Bay (a couple of years ago a party of 20-several Chinese
illegal immigrants got killed there), and his description very much
mirrors this. The killers are normally not drowning in the sand, but
a combination of hypothermia, crush injuries, heart attack, and having
your head 0.5m above seabed when the tide rises by 3m. Their rescue
techniques are honed for speed, not prettiness. They take a number of
lightweight "crawling boards", a extra safety line and chest harness
for the victim, plus a looooong air hose with a 1.5m long rigid pipe
on the business end. Crawl out to the victim; put on the chest harness
and attach hauling rope; push the air pipe down the back of their body;
turn on the air and the bubbling breaks the seal and generally
re-liquifies the sand/ mud around the victim; the shore team then
haul the victim onto solid ground as fast as reasonable (depending on
injuries, heart attacks and how much aversion therapy they think is
needed).

ObDino - could you drag a Brontosaurus out of a quicksand by the
tail, or would it snap off?
