Topic: Wierd question about the roasting smoke (was Re: +My first foray into Bread Machine Roasting.) (11 msgs / 478 lines)
1) From: Silvia Marsh
Floyd said: I ended the day feeling quite pleased and noticed that I don't
have the normal headache and shakes I have when roasting over the dog bowl
on the grill for supplemental heat.  i think i might have been getting some
low grade CO poisoning there or something.
Okay, I'm kinda curious about this now...I know if I roast a lot in a day,
I'll tend to get a touch of that too, and I roast indoors with a FR+8. At
first I thought it was just inadequate ventilation and smoke, so I now make
sure to have the air circulating more and the back door open.
Somebody mentioned at one time on the list inhaling caffeine while roasting,
and I took it as a joke...now I'm kinda curious.
Do you really inhale caffeine when roasting (and would it affect you if you
did), or could it be low-grade CO2 poisoning like Floyd mentioned? Or could
it really just be an inadequate ventilation thing?
Just curious,
Silvia

2) From: Floyd Lozano
I meant CO, carbon monoxide, which I assumed i was inhaling while standing
over my blast furnace like grill for extended periods.  CO2 isn't poisonous
like CO is.  My understanding of this is (forgive me, non-chemist) the
reason CO is poisonous is that the mechanism which carries oxygen around in
your blood seems to really prefer to carry around CO.  CO displaces the
oxygen and takes a longer time to unbind (since your body is all like wtf,
CO?  I asked for O2!) and won't pull it off.  You don't have that problem
with CO2 though, your body makes it and then says 'oh yeah, time to take out
the trash' and peels it off in your lungs and expires it!
I wondered for a while if it was just caffeine in the smoke and maybe it is,
but just that with a bread machine i am not standing right over the smoke
source.  I can stand an extra foot away since i rest the gun on the edge of
the bread machine and point the schnozzle inside.  Much harder to wave a 3lb
gun for 15 min at arms length 2 or 3 times in an hour!
So in the end, I don't know which it is.  I used to roast 3 or 4 times a
night with the FR8+ but since my house is kinda wide open, the smoke
probably didn't concentrate in one area so much. I don't recall ever getting
headache with that thing.

That is basically how it works, Floyd.  Hemoglobin has a greater 
affinity for CO than for O2.  And because of this, the hemoglobin then =
has a much reduced oxygen carrying capacity (depending on how much CO 
exposure there was.)  The interesting thing is, even tho the body is 
then essentially being starved of O2, the victim continues to appear 
oxygenated (ie red.)  CO2 can be a problem, as well, if one is in an 
environment where the concentration is very high.  This is not likely 
under normal circumstances.  Also, CO2 is dissolved in the blood, so, 
as you say, it is easier for the lungs to rid the body of it... 
assuming one does not have lung disease.
It is an interesting question, whether the symptoms experienced were 
caused by CO or caffeine.  Or perhaps something else entirely.
Hmmm....

Let me give you at least partial reassurance.  I just ran a couple of =

the outlet.  I read zero for the entire roast.  (average and peak =
readings)
I tested it with the self-test function, by blowing cigarette smoke at =

cigarette with enthusiasm (but didn't reach the 400 ppm alarm =

Roger,
Well... that is good to know.  Nice little test.

Ginny,
You must be off the radar again, "Granny Growers" only googles
out to apples.
And, I do recall reading about caffeine being in the smoke, I
know I have sleep issues if I roast late in the evening with my
Gene Cafe inside my garage.
Bob

7) From: Silvia Marsh
Good information, all, thank you...
Basically, I can deal with inhaling caffeine or normal smoke in the small
amounts my little roaster produces; I just wanted to make sure I wasn't
accidentally damaging myself by roasting in a relatively non-ventilated
area. If that'd been the case, well, I just woulda moved my Freshroast onto
my computer desk to be right next to the window. ;)
Hrm. Might anyway. *grins* Roast while I babble online...this could get
ugly...

Careful now.  Humans can tolerate all manner of smoke, but computers are =

11) From: Ed Needham
I always get a caffeine buzz from roasting with my drum/grill setup.  If you 
are breathing coffee smoke for any length of time, I'm sure you'll get a 
buzz too, and maybe a headache if caffeine gives you a headache.  Doesn't do 
that for me.  Maybe the noxious intensity of the smoke caused the headache.
There's hardly any CO discharged from a propane grill.  CO occurs when there 
is incomplete combustion, and propane pretty much burns clean ad complete.
