Just got this interesting and possibly useful bit of info-
----
Well, here goes. Tear gas, CS and CN, are typically chemicals imbedded in
*smoke mix* or *pyro mix*... smoke grenade material. They are
launched/thrown, and a few seconds later, *go off*, or *function*-- begin to
smoke when the mix inside the case begins to burn... yes, burn. The chemical
precipitates on the smoke, which is composed of nothing more than soot
particles.
I will speak to a condition in a house/building.
If you suspect that you may receive a visit, you can be prepared. Heavy
chicken wire over the windows may well prevent their entry. This can be
attached to a frame and secured inside the structure, not in plain view from
outside. SURPRISE!
On the inside, you will need a pair of gloves, or a ready-rag or something
to prevent burning your hands. Thin deerskin leather makes the best thin,
rough-duty gloves I've seen. Cloth/fabric *work* gloves or anything else
will work.
Sodium or calcium hypochlorite (*bleach*) *kills* the CS/CN. Chemically
discombobulates it. It can be purchased fairly cheaply in bulk, powder
form... go to your local swimming pool store. Strategically place a few
5-gallon METAL buckets around the house, with lids, and put a quart or so
dry bleach in each bucket. Leave the lid on, but loose. If you have time,
even a minute or two, fill the buckets about 2/3 with water in the bath tub
and quickly stir up the bleach, leaving the lid nearby, handy.
When your visitors offer their hostess gifts, snatch them up and drop them
in the buckets. Put the lids on, but loose. They will now be unable to start
a fire (which they often otherwise do), their smoke will be largely
contained, and it will be largely *neutralized* of their noxious chemical.
You don't use the plastic buckets because the hot grenade will melt right
through... and the smoke mix doesn't need air to burn, so once ignited,
dunking it will not automatically extinguish it. And the smoke grenades will
occasionally burn so fast anyway that they will *pop* the case, bursting or
splitting it because it produces gas so quickly it overpressures the case,
which fails. This tendency will be made worse, made more likely by
submergence, because it puts a back pressure on the grenade case where the
gas is being generated. The metal bucket will also help contain the pressure
surge much better than plastic. If the grenade does *pop*, the pressure wave
will likely propel much of the liquid from the bucket, but by that time you
have largely contained their effect, anyway.
Keep a BIG jar of vaseline handy, and cover all exposed skin, extending
under the edges of clothing.
