Co2/Painting/Heaters

I had an unusual experience this weekend (and yes, my Pants were on the entire time)-I Epoxy primed my '35 (again!) for Blocking-I got up at 4 a.m. Saturday morning, went down and turned on my Heaters (plural)-I have some Kerosene Heaters and did NOT use them, I used a combination of Electric Heaters this time to warm up my Shop-I placed three inside my Coupe to warm up the Metal, and placed the others in various places around my Shop-went back inside, had Breakfast and came out to see how things were coming-shot the Metal with a Temp Gun, was around 85 degrees (toasty!), and the Shop was plenty warm-

Tack rag, shot a coat of Primer-waited 4 Hours, tacked and shot it again-waited five Hours, tacked it, shot it again-(by the way, before I shot the first coat I took the Heaters out of the Car)-I left the Heaters on all night Saturday night, checking them frequently-it never got below 80 degrees. Because of all of the Posts on here, I went out last weekend and bought a Co2 Detector and put it in my Shop-

So, what's the problem? When I went down to check it yesterday morning the Co2 Detector was going off-now, yes, I must be dense (no, I don't need anybody confirm this!), but why did the Detector go off? It was Electric Heat-I will tell you that my eyes were watering when I went in there-

35WINDOW,

Good move getting the CO2 detector. I need to do the same for my shop. However, electric heaters can't generate CO2. The CO2 must have come from another source. As the formular implies, carbon monoxide is made up of one carbon atom and 2 oxygen atoms. There is no carbon in air. You need a hydrocarbon fuel and a combustion process in which carbon atoms from the fuel and oxygen from the air combine in the right proportions. Did you have oil somehow contaminating the heating element? Any open flames like a water heater nearby?

Alan

alan,

Thanks for the Post-I had come to the same conclusion as the only other thing running was my Compressor and lighting-that's why I am confused-no, there is no other source of running Gas in my Shop-I have to admit that I did not open the Doors after the first coat as I did not want to let in the cold (it was snowing), so, I know that the air was dense w/Epoxy fumes-I wore a respirator, but when I was done it did make my eyes tear up although the dectector did not go off unitl sometime in the night-obviously there was something in the air that set it off and I can't figure it out-I wonder if somehow the curing of Epoxy had anything to do with it as the Temps were high?

CO2 is Carbon Dioxide, what we breathe out.
CO is Carbon Monoxide, by-product of combustion.

Car fumes will set your CO detector of very quickly.
Could there be fumes from you furnace leaking into your garage?
Some detectors will go off very quickly if there is a lot of CO in the air but will wait an hour or so if there is a low amount, this is done to prevent false alarms.
Could always be a faulty detector.
CO can travel up or down into the garage as it is nearly the same density as air.
I don't know what epoxy fumes consist of but is it possible these fumes set it off.?

The detector may have been triggered by something other than CO2. Possibly the solvent or resins venting from the epoxy. A home CO2 detector is a compromise, yes it will detect CO2 as well as other things.

Most of the battery powered detectors are junk.
I've only found 1 which would compair with the 800.00 one I use at work. Nighthawk brand. They run on 120v and the one's I buy have a display read out in ppm. Yeah, Wally World.

Thanks guys,

I believe you are right-could be more than one thing-guess since I wasn't in there when it was going off I'm o.k.-I bought one of the pricier units that Home Depot had, but I'm sure you are correct-they are probably a crap-shoot at best, but I guess something is better than nothing-

Co2/Painting/Heaters

this is a good question
i have a what i did suggestion
buy some 6 inch air duct
cut hole through wall at floor level
run the pipe up the outside of your garage and
about roof high.
this will draw your fumes out without drawing your heat
being cold air stays low as do the fumes.
make a door you can close , but i leave mine open .
this helps with gas rags and other automotive products that
smell like carburetor and break cleaner.
like most shops or garages there will be enough fresh air through the doors
for the vent to draw .
i hope this helps you
it might keep your roof on along with your pants .
