Dear Editor,
We have lots of trouble with the M56 smoke generator's weapons stor-
age case not sealing out water. The M56s sit between missions and
nobody thinks to open the weapons storage case during PMCS. When the
case is opened, operators find standing water in the bottom and any BII
that's been stored in the case starting to rust.
We suggest smoke
units open up the storage
cases every week and
check for water. If you
find any, mop it up. It's a
good idea to just leave a
big sponge in the case to
make it easier to mop up
the water.
If you're in an area with lots
of rain, have your direct sup-
port drill a drain hole in each
end of the case no larger than
3/16 inch and about 1/4 inch
from the bottom and front side
edges. Empty the case before
drilling. Touch up the area with
paint to prevent corrosion.
That way water can't collect.

•
Starting with the filter end, coil the
suction hose inside the box, making
sure the hose is not kinked. It takes
two people to do this.
•
Coil the branch hose on top of the
suction hose, placing the wands and
shower in the center.
•
Coil the pressure hoses individually
and put them at each end of the box.
•
Coil the syphor injector hose and
put it in the middle.
O
nce your M17-series decon's suction hose dies, so does your deconning. You
can't decon without water and you can't get water without a suction hose.
The reason a suction hose gives out is usually that a section of it collapses.
Anytime water pressure starts drop-
ping, make the suction hose your
first check. If the hose has collapsed,
there's no fix except to replace the
hose. That's why it's a good idea to
have backup hoses available. When
you have any M17 hoses made,
order extras. You'll need them.
Suction hoses usually collapse either from the heat or from being stuffed in the
storage box. There's not much you can do about the heat, but you can store hoses
correctly. Here's how:
