M40/M42-Series Masks…
A Drink Tube Clean Enough to Drink From
I
magine how gross it would be to drink through the same straw day after day. It will
be equally gross if you don't keep the drinking tube in your M40 or M42 mask clean.
Lots of nasty stuff can form in the tube over time and you end up drinking it in.
Keeping the tube sanitary doesn't take that much effort.
Simply flushing the tube with water will get rid of most gunk. Be sure to remove
the filter canister before flushing. Fill your canteen with clean water and attach it to
the external drinking tube. Turn the canteen upside down and squeeze it while hold-
ing the facepiece upside down with the internal drink tube facing away from the
facepiece. Do this until all the water runs through the drinking tube. Do this twice.
But if you've been training with
your mask quite a bit, the tube may
need more serious cleaning. Get
calcium hypochlorite, NSN 6840-
00-242-4770, from your NBC
NCO. It's part of the expendable
supplies for the masks. Mix 1/2 tea-
spoon of the hypochlorite with a
gallon of clean water and fill your
canteen with the mixture. Make
sure the hypochlorite is completely
dissolved. Run the mixture through
the drinking tube and then run 2
canteens of clean water through the
drink tube.
I wish there
was someplace
I could go
for help.
there is, my
good man!
look at the
chem school’s
internet site.
they’ve
got
all
sorts
of info.
Never drink anything but water
through the drinking tube. Stuff like
sports drinks will really foul the tube.
NBC NCOs, when you're issuing a
used mask to a new soldier, put on a
new internal drinking tube. Tubes are
cheap and a new tube helps stop the
spread of germs.
These
procedures
can be found
on Page 2-

that soldier
should have paid
more attention to
keeping the drink
