Filters are your friend. :)

Ouch! Mea culpa.

Yes Bubaa , bottom line, you post like what you are, a a 9 yr old imature child. Merry Christmas

How Much Carbon Monoxide is Considered Safe?:

Standards which specify safe levels of CO in the home and workplace are the subject of current debate. The Consumer Products Safety Commission (CPSC) recommends against exposure to levels averaging greater than 15 ppm CO for eight hours or 25 ppm for one hour. The National Institute for Occupational Safety and Health has established an eight-hour average limit of 35 ppm CO and a ceiling level of 200 ppm for workplace exposures, while the American Council of Government Industrial Hygienists' guideline is an eight-hour average of 25 ppm. The U.S. Occupational Safety and Health Administration (OSHA) had established an eight-hour average limit of 35 ppm CO and a 15 minute exposure ceiling of

200 ppm for workplace exposures under its 1989 air contaminants rule. However, on July 7, 1992, the U.S. Court of Appeals vacated the air contaminants rule because OSHA failed to establish that a significant risk existed for each of the over 400 substances covered by the rule. The enforcement of those limits was suspended starting March 23, 1993, and the CO standard reverted to the pre-1989 eight-hour average limit of 50 ppm and a 15 minute exposure ceiling of 200 ppm for the workplace.

So what the Fuck is your point BOB

[JerryMouse]

That's why many come to this newsgroup: to learn.

Nope. Density is a function of pressure and temperature. For example, solid CO2 (dry ice) is way heavier than air. Likewise solid CO. In a room, the molecules of CO (or of the cat, for that matter) become warmer and colder as time passes and they move around (see "Entropy"). You can prove this for yourself. Stick your finger in the fire: Ow, HOT! Quick, stick your finger in a jar of mayonnaise. Ah, cool! Can you write C-O-O-L on the mirror? Tommorrow, we'll discuss things you can do with mayonnaise and a rubber-band.

Trust me on this: proof does not lie in the bottom of a CrackerJack box.

Experts disagree with Bubba's assertion that 9ppm is bad.

[Ed Clarke]

No they don't; those are eight hour legal limits. I doubt that you'll find any expert that will say that even 1ppm is good for you.

To jerk this flame-fest back to the original posting, any CO detected indicates a problem. If your CO detector isn't bad and is reading somewhat accurately, 14PPM indicates a dangerous situation. Not only is something burning incompletely, but whatever it is is leaking toxic gas into your living area. Get it fixed right away.

Im afraid this is way over your head mr webtv boy. You'll have to sit in the back of the class and learn today Bubba

[Bubba]

Well, its nice to know there are still those wearing that tin foil hat. :-) Bubba

[Bubba]

So you're telling us then that you cant even follow along with 9 yr old mentality? Once again, it must suck to be you. You'll never learn with your mouth wide open. Bubba

I hope we don't get in a shouting match about this. There are a lot of compromises about setting exposure limits, I speak from personal experience having sat on committees that set these type of limits. Usually you have to assume worst case. For example assume that you are setting a CO limit; you need to consider one that is okay for someone who both smokes and has restricted lung capacity. Physically CO ties up hemoglobin and prevents it from carrying oxygen. Fortunately we have a lot of excess oxygen carrying capacity so that loss of 10-20% oxygen carrying capacity is not noticed for normal individuals. The exhaled breathe of smokers (after they have finished smoking) is 5-10 ppm of CO. I still would recommend trying to track down the source of CO or at least make sure it is not increasing with time.

I am not sure what the normal reading of a CO meter is in a house with natural gas heat and stove should be in the winter -- anyone care to comment.

[m Ransley]

Nornal Co should be Zero=0. There are 8 hr exposusure limits for Radiation do you want them ?

[Norminn]

I know four people who are alive in spite of a bad CO leak because they had an old drafty house. I was the only one who had symptoms, which were rather intense. I persisted in trying to find an answer to why I noticed what I noticed. When the owner got the gas company to come take a look, they would not let residents back into the house without correcting the problem - bad furnace.

I know another couple who were being gassed with CO in a new home because it was sealed up very tight and the fireplace drew fumes back into the house from gas appliances.

Nobody, ever, should be in a home with a suspected CO problem without having it checked out. The gas company or the fire department should be contacted right away. I would not stay in the home without checking it out.

[Bubba]

Holy shit! Just when I thought you actually sat back and learned something (Nornal Co should be Zero=0.) ........................ then all of a sudden you drift off into radiation exposure? WTF?? Bubba

[Eric]

Not a gas stove, a gas fireplace. Thanks, Eric

This is Turtle.

the fellow with the CO staying on the floor lives on the other side of the earth from America like China and down is up and up is down. CO goes down in China and up in American. I think that is why we have trouble understanding them for they are always backwards from us.
