**** This new thread will self-destruct in 48 hours ****
There is an article on the web, suggesting that dust mask are ineffective
at preventing the wearer ( caver ) from breathing in dust particles.
http://news.discovery.com/human/health/face-masks-provide-false-hope-against-pollution-140228.htm
It does seem like cavers visiting very dusty caves, should wear breathing
respirators, that have a rubber seal around the nose and mouth and replacable
canisters. Especially if you are going to be sturrying up the dust
by digging.

Unfortunately, those mask appear cumbersome and uncomfortable, especially when
exerting yourself, sweating, etc.

An N100

or similar mask should be effective enough for most normal applications and
won't be particularly cumbersome or obtrusive. If you need more protection than
that you're probably in a bad-air cave and should probably be wearing a
rebreather.

Howdy Texas Cavers!
At this week's grotto meeting, renowned TV personality Dr. Jean Krejca will
be showing the ITV Studios film from her last trip to the magnificent karst
in China, 'Mystery Caves of Guanxi'. As a bonus, she will be providing
live commentary on the background details of the filming and taking
questions.
We will be meeting at 7:45pm in *Burdine 136*. Follow this link to a map of
where the building is located on the University of Texas campus:

For information on Underground Texas Grotto activities, please see

Before the meeting, take advantage of Sao Paulo www.saopaulos.net for
happy hour specials. Attendance by cavers varies but this area is the best
place to park and meet folks walking over to the meeting. Then after the
official meeting, we continue with the decades long tradition to reconvene
for burgers, beer, and tall tales of caving at Posse East.
