COMMON SENSE ON BIO AND CHEM HAZARDS

Just give me credit for my work, and, keep in context.
Since the media has decided to scare everyone with predictions of chemical,
biological, or nuclear warfare on our turf, I decided to write a paper and
keep things in their proper perspective. I am a retired military weapons,
munitions, and training expert. Lesson number one: In the mid 1990's,
there were a series of nerve gas attacks on crowded Japanese subway stations.
Given perfect conditions for an attack, less than 10% of the people there
were injured (the injured were better in a few hours), and only one percent of the injured died.
60 Minutes once had a fellow telling us that one drop of nerve gas could
kill a thousand people; well, he didn't tell you the thousand dead people
per drop was theoretical. Drill Sergeants exaggerate how terrible this
stuff is to keep the recruits awake in class (I know this because I was a
Drill Sergeant, too).
Forget everything you've ever seen on TV, in the movies, or read in a
novel about this stuff, it was all a lie (read this sentence again out loud)!
These weapons are about terror; if you remain calm, you will probably not
`die. This is far less scary than the media and their "experts" make it sound.
Chemical weapons are categorized as Nerve, Blood, Blister, and
Incapacitating agents. Contrary to the hype of reporters and politicians,
they are not weapons of mass destruction; they are "area denial," and
terror weapons that don't destroy anything. When you leave the area you
almost always leave the risk. That's the difference; you can leave the area
and the risk; soldiers may have to stay put and sit through it, and that's
why they need all that spiffy gear.
These are not gasses, they are vapors and/or air borne particles. The agent
must be delivered in sufficient quantity to kill/injure, and that defines
when/how it's used. Every day we have a morning and evening inversion where
"stuff," suspended in the air gets pushed down. This inversion is why
allergies (pollen) and air pollution are worst at these times of the day.
So, a chemical attack will have its best effect an hour of so either side
of sunrise/sunset. Also, being vapors and airborne particles they are
heavier than air so they will seek low places like ditches, basements and
underground garages. This stuff won't work when it's freezing, it doesn't
last when it's hot, and wind spreads it too thin too fast. They've got to
get this stuff on you, or get you to inhale it for it to work.
They also have to get the concentration of chemicals high enough to kill or
wound you. Too little and it's nothing, too much and it's wasted. What I
hope you've gathered by this point is that a chemical weapons attack that
kills a lot of people is incredibly hard to do with military grade agents
and equipment, so you can imagine how hard it will be for terrorists.
The more you know about this stuff, the more you realize how hard it is to use.
We'll start by talking about nerve agents. You have these in your house:
plain old bug killer (like Raid) is nerve agent. All nerve agents work the
same way; they are cholinesterase inhibitors that mess up the signals your
nervous system uses to make your body function. It can harm you if you get
it on your skin, but it works best if they can get you to inhale it.
If you don't die in the first minute and you can leave the area, you're
probably gonna live.
The military's antidote for all nerve agents is atropine and pralidoxime chloride. Neither
one of these does anything to cure the nerve agent; they send your body
into overdrive to keep you alive for five minutes. After that, the agent is used up.
Your best protection is fresh air and staying calm. Listed below are the
symptoms for nerve agent poisoning:
Sudden headache Dimness of vision (someone you're looking at will have pinpointed pupils)
Runny nose
Excessive saliva or drooling
Difficulty breathing
Tightness in chest
Nausea
Stomach cramps
Twitching of exposed skin where a liquid just got on you
If you are in public and you start experiencing these symptoms, first ask
yourself, did anything out of the ordinary just happen, a loud pop, did
someone spray something on the crowd? Are other people getting sick, too?
Is there an odor of new mown hay, green corn, something fruity, or camphor
where it shouldn't be? If the answer is yes, then calmly (if you panic, you
breathe faster and inhale more air/poison) leave the area and head up wind,
or outside. Fresh air is the best "right now antidote." If you have a blob
of liquid that looks like molasses or Karo syrup on you, blot it or scrape
it off and away from yourself with anything disposable. This stuff works
based on your body weight. What a crop duster uses to kill bugs won't hurt
you, unless you stand there and breathe it in real deep, then lick the
residue off the ground for while. Remember, they have to do all the work,
they have to get the concentration up and keep it up for several minutes,
while all you have to do is quit getting it on you/quit breathing it by putting space
between you and the attack.
Blood agents are cyanide or arsine which effect your blood's ability to
provide oxygen to your tissue. The scenario for attack would be the same as
nerve agent. Look for a pop or someone splashing/spraying something and
folks around there getting woozy/falling down. The telltale smells are
bitter almonds or garlic where it shouldn't be. The symptoms are blue lips,
blue under the fingernails, rapid breathing. The military's antidote is
amyl nitride and, just like nerve agent antidote, it just keeps your body
working for five minutes till the toxins are used up. Fresh air is the your
best individual chance.
Blister agents (distilled mustard) are so nasty that nobody wants to even
handle it, let alone use it. It's almost impossible to handle safely and
may have delayed effect of up to 12 hours. The attack scenario is also
limited to the things you'd see from other chemicals. If you do get large,
painful blisters for no apparent reason, don't pop them; if you must, don't
let the liquid from the blister get on any other area, the stuff just keeps
on spreading. It's just as likely to harm the user as the target.
Soap, water, sunshine, and fresh air are this stuff's enemy.
Bottom line on chemical weapons (it's the same if they use industrial
chemical spills) -- they are intended to make you panic, to terrorize you,
to herd you like sheep to the wolves. If there is an attack, leave the area
and go upwind, or to the sides of the wind stream. They have to get the
stuff to you, and on you. You're more likely to be hurt by a drunk driver
on any given day than be hurt by one of these attacks. Your odds get better
if you leave the area. Soap, water, time, and fresh air really deal this
stuff a knock-out-punch. Don't let fear of an isolated attack rule your
life. The odds are really on your side.
