Exposure Limits - Carbon Monoxide

35 PPM 8 hours Maximum before symptoms

200 PPM 2-3 hours Mild headache, fatigue, and nausea

400 PPM 1-2 hours Serious headache- Life threatening

800 PPM 45 minutes Dizziness, nausea and convulsions. Death within 2-3 hours.

1600 PPM 20 minutes Headache, dizziness and nausea.
Death within 1 hour.

3200 PPM 5-10 minutes Headache, dizziness and nausea.
Death within 1 hour.

6400 PPM 1-2 minutes Headache, dizziness and nausea.
Death within 25-30 minutes.

12,800 PPM 1-3 minutes Death.

While 12,800 sounds like a lot...its only 1.28% Which is Why it is so lethal.

Just some info. These are the accepted results for various exposure limits.

Please feel free to use this info.

    LEL

    And with a LEL of 12.5% (heaven forbid any appliance cranks that out) makes for a darn good fuel gas too!

    Just remember

    Just keep in mind that these numbers were come up with in a study on Navy Seals done in the early 1950's.

    This study was done on young, healthy, male, military recuits using CO instruments that really weren't near as accurate as the digital equipment we have today.

    Frankly, I'd take these numbers with a 'grain of salt'...

    Studies done more recently sure seem to suggest lower levels have a huge impact on the general population (which includes elderly, infants, women, and those with pre-existing health problems).
