Fascinating. There is always some CO in the air. What is the unit's lower
detection limit?

I believe that the origin of this thread was someone's allegation that somebody
had died of CO poisoning when they went in their kiln room during a firing. ie:
said person walked in the room and was immediately overcome, literally before
they knew what hit them. Others dissented, and I think someone offered to look
up an article in a magazine as proof of the allegation.

Did said article or any other proof of the above allegation ever materialize? I
have lost quite a bit of clayart and other email over the weekend due to
reformatting the computer, and thus missed the resolution of the discussion.

Thanks in advance y'all.

Hmmm. I may have mispoken. I assumed it was a continuous monitor because
of the LED readout, but upon turning it over, I find that it's set to go
off at 200 ppm over a 35 minute period. Maybe some day when everyone's
away, I'll choke off the return air to the furnace and see what happens.
What fun!

Well, I'll never be wrong again. The unit is, at least, UL-approved.

Hi Lisa

Attached is the earlier 'CO death' thread. By way of clarification:

1. The evidence does NOT suggest the victim was overcome upon walking into
the kiln room. It does seem she had been there awhile already, and was no
doubt tired - to the point that she overlooked the damper being closed as she
fired the kiln the second time. As a result, there was far more CO in the
room than a normal firing would have caused.

2. As for the report's corroboration, it's up in the air. Ceramic Review
(ceramicr@globalnet.co.uk) has not yet replied to my email asking if they can
trace the source issue. If it's not in their year on year index of contents,
we're looking at one or two hours of heavy duty thumbing-through. This needs
a motivated volunteer. The ample Ceramic Review collection in which I found
this report is over a thousand miles away (I'm in northern California) - or
I'd have traced it already.
If I were searching I'd focus on the late 80's and early '90s back issues.
And should I yet hear from Ceramic Review, I'll pass it on.

UL are the idiots that changed the limits to keep fire departments happy. I
called them and bawled them out at the time. Also wrote an article about
what I think of the new limits. Instead of caving in to the fire
departments, they should have gotten into a public to understand that when
these devices read out higher that normal limits, they should find out what
is wrong on their own or call the gas company. Fire departments should only
respond when the devices alarm at the new high limits.

Whenever UL or any other organization says that something "meets standards,"
ask who is on the committees that set the standards. That would be an
eye-opener. The committees are almost always primarily made up of the very
manufacturers of the items for which standards are being set.
