Holy sh-t:
“There was talk of carbon monoxide (CO) being a good stimulant for EPO production”
Great, why don’t we just run our cars with the garage door closed. These people realize that CO is toxic, right? That people go to the hospital for CO poisoning. That people in refineries and power plants carry CO monitors so they don’t suddenly collapse and die.
Any ergogenic aid that requires a doctor’s supervision should be banned outright.
You do realize that oxygen is toxic right (given the right concentration and exposure)?
You do realize that Chromium is an essential nutrient right (and is also considered toxic at the right concentrations)?
Why do you objectively condone doping?

Aww cmon, don’t slight him for that.
It’s always easier to read an article on the internet, take it as it is, and then get angry 
Don’t waste your time.
It comes with my job I suppose (civil and environmental engineer). One of those things where there is a fear about something like floride because it’s toxic, when in reality that’s not the case for the concentrations people are exposed to through a public water system. I spend so many hours of my left supplying safe, reliable delivery of water, it makes me cringe every time I see a plastic bottle.
Also, I’m not condoning doping. Hell, I don’t even take ibuprofen or vitamins. I very much agree with Prentice Steffen’s stance that he wants to be aligned with the intent of rule, as opposed to existing in all of the gray areas of the rules.
Water’s toxic in the right amounts too!
I think it’s also important to point out your type of chromium. There’s a substantial health difference between Cr(III) and Cr(VI).
Pink text.
I see where your’re coming from; also in my world, flouride ions dissolved from NaF or the like in water is meh. HF in a solution is deadly. Not one drop.
Anyway, where I’m coming from is that CO is considered toxic at pretty much any concentration (Almost all concentrations? most concentrations? is there a toxicologist in the house?) what matters is the duration of exposure. Oxygen, at naturally occuring concentrations, is not. Neither is water (unless you try to breathe it, or drink a lot quickly). Indeed, they’re necessary for most life as we know it to exist. Not CO.
I just have this vision in my head of some squad breathing in fumes from an open fire or something and getting extremely sick. If not dead. In my real world, any employer that would require unprotected exposure to CO would end up out of business, or in jail.
Which again is why I admire Dr. Steffen’s stance to follow the intent of the law. With doping control action limits being ratios at times, I have little doubt that people dope to artificially get their ratios to the highest possible limit. Violates the intent of the rule, but can get a person through doping controls.

Many workers are routinely exposed to CO without any respiratory protection. OSHA sets the CO exposure limit at 35 ppm (time-weighted average). 200 ppm for short-term exposure (a few minutes).
IDLH (immediate danger to life and health) is at 1500 ppm.
EPA air quality standards are 9 ppm (this assumes 8-hour exposure).
Not to downplay the risks of CO, but the effects are predictable and reversible (for levels within reason). The hemoglobin in your blood has a much greater affinity for CO than for O2. So if you inhale a molecule of CO, it is very likely that it will be snapped up by a hemoglobin molecule, which will then hang on to it for some time (1/2-life of about an hour). Once the hemoglobin gives up the CO you are back to normal, as long as you had enough unaffected hemoglobin to still deliver sufficient oxygen.
What CO does is to take away some of the capacity of your respiratory system. So it’s only toxic when respiratory capacity is highly impaired, since most healthy people have excess respiratory capacity.
Cigarette smoking is a good way to inhale CO and increase your hemoglobin levels…

Not true. Carbon Monoxide is therapeutic / anti-inflammatory at appropriate doses. It is also integral to Hemoglobin mass determination. Thesting which does not signficantly impair athletic performance.

Openly doping!!
Are those extra tires wrapped around them? I’ve always wondered and this is the most logical answer I have come up with so far.

yep
Yes. Back then they had the same rules as mountain biking does now. Which is: a rider has to do his own repairs including fixing flats.

Kudos to him and Garmin for steering clear. I’m guessing we’ll hear some teams (Sky, Astana, etc.) give really generic answers about following all rules when asked if they used CO or Xe.

Is Darwin on our forum? Can he chime in on this one?
So it’s only toxic when respiratory capacity is highly impaired
Sounds like to me that it’s toxic for everyone, and the effects become acute more quickly when respiratory capacity is impaired.
It’s nice having extra capacity though. I spent half a day with a collapsed lung without realizing it.
