I didn’t find a single article that stated anything about bloodshot eyes deriving from carbon monoxide. Not to say that it wasn’t an issue as it’s probably a combination of the fuel & CO.
I noticed a track worker pouring fuel onto the X drawn in the start straight shortly before the opening ceremonies. I wonder what type of fuel that was because once it was lit, it burned for quite a while & that could also have contributed. A lot of pyrotechnics went off as well. Made for a decent show, but for a sealed off building, not so much.
Honestly, they could just use a decent premium pump gas and tell everyone "This is what you get. Tune your engines for it."

In MotoAmerica (road racing) we have spec fuel. It's VP MGP and it's absolute garbage. Makes about the same power as pump 93 from WaWa. The difference between MGP and say VP's MR12 is about 8 horsepower. Obviously, this gain on a smaller engine would be less but the gain is still there.
I agree that the cost is dumb for the top fuels and we don't need it. $25+ a gallon. Even our junk MGP is $18 a gallon. Which is insanity considering its not good fuel.
The main products from combustion are water and carbon dioxide and carbon monoxide from incomplete combustion. These don't fit the symptoms people are saying.
If there are traces of nitrogen or sulfur in fuel, then you can get acidic components (acid rain), however, I doubt that's an issue with highly processed racing fuels.
HVAC monitors would be tracking Carbon Dioxide, which is exhaled by people and makes a room feel "stuffy" when too much of it builds up (and makes the people in the room feel sleepy). CO2 monitoring provides assurance that you are bringing enough ventilation into a room for normal use, and can be used as a proxy measurement for how many people are in a building. Building codes are aimed at providing enough outside air in a commercial building to offset the CO2 generated by the occupants.
CO2 is not the same as CO (carbon monoxide, which seems unlikely to be an issue here) or whatever fumes the bikes and fuel are putting into the air.
I've never designed an NFL stadium before, but I think it would be very unlikely they have any equipment to monitor whatever was in the air that made people sick.
My main point was that the FB posts by the stadium itself is promoting the idea that they have a bunch of monitoring equipment in their HVAC system, but those monitors aren't monitoring whatever it is that made people sick.
As pointed out by others, the system in the building certainly has the capability to provide adequate ventilation. Someone done f'ed up

Also, I've read msds and they use small amounts of alkyl bromides.. these are often lacrimatory, and have the added bonus of reacting with DNA to give you cancer.
Needs to be a VOC sensor which no HVAC system has by default.
So air was polluted, they just could not catch it.
I strangely enough didn't experience any issues with my eyes, just felt miserable the next day because I drank 3 beers at the race & a bunch more afterwards and it was the first time I drank in nearly 4 months. The 3 of us in my group all wear contacts, could that have been something that helped? We were only there for the night show.
For the MSDS & alkyl bromides, which products? VP's 4-stroke fuels? Are those alkyl bromides acutely toxic or more of a low-level repeated exposure long term toxin?
Pit Row
I've not been close to a bike with race fuel in it but I'd believe your take on how potent the smell is. When we were walking in through the skyway, I could smell something that was just odd, but I don't think it was the race exhaust unless it was an "aired down" version of exhaust. I thought it was weird to be smelling it when bikes had been off the track for over an hour at that point though.
Otherwise, could it have been fuel vapors that got sucked into the HVAC system and distributed throughout the whole facility?
Also, why would a race fuel product have lacrimatory components? Help produce more power?
Was anyone here in the pits at all? Were there race fuel cans stored in the pit areas inside the stadium?
Not trying to be melodramatic here, but fuels can contain nasty stuff... of course, so do many things and it all comes down to the amount and the frequency of exposure.
I looked upVP pro6 and it contains up to 48% isoproprene as well as ethers and aromatics such as toluene.
Benzene is a known carcinogen, toluene isn't as bad.
Isoprene is nasty stuff and I think it's responsible for fhe bad smell. Ispprene polymerizes. Just like styrene turns into polystyrene. To polymerize , it needs to be reactive. If it's reactive, it can react with tissues.
