A better article to read instead of watch:

https://www.cbsnews.com/news/los-angeles-airport-carbon-dioxide-leak-4-sickened/

And even then it kinda sucks, but at least you can read it.

Edit, maybe this one:

/Much obliged.

What poor reporting. We exhale carbon dioxide (CO2). The CBSNews article's headline says CO2 but in the article states carbon monoxide (CO).

C02 is deadly as well. It's normally a trace gas, a 400ppm baseline translates to .04% of air. Pipes of c02 can be very hazardous.

.

Main thing about c02 is that because our bodies exhale it, we are wired to detect c02. Sort of, it does not stink like a smell.

This makes it a lot more rare to be poisoned by than other gasses, but it still happens.

There was work going on in a computer room, and the fire suppression system kicked on displaced the air with the people inside.

And this hazard is possible in just about every gas station, restaurant, etc. that has carbonated soft drink dispensers. A quick search will tell you that it's not really all that uncommon with the concentrated tank systems that they now use.

That was a hazard all the way back to the 60s, at least. I remember hazardous materials signs in the co2 tank area.

You'll get a headache and dizziness, from either CO2 or CO.... But CO is harder to purge from the bloodstream

Right, I should have specified that I was attempting to say deaths/serious poisonings are not that common due to our bodies being built to expel the c02.

.

I personally have an air quality sensor next to my desk right now because mystery migraines after a move turned out to be c02.

Only happened when my doors+windows were shut and heat turned on.

And from what I understand it's worse now because the soft drink syrup mix and the CO2 are no longer in the same tank like they used to be. Newer systems have the syrup in cardboard surrounded plastic bladders with the CO2 fed in by one main large tank to the individual dispensers.

If there was a leak in the older premixed tanks, while it was still a danger, today's systems present an entirely different problem. Most modern systems have several feet of CO2 lines that are fed by one large CO2 tank. If the tank, regulator, or any of the lines leak or malfunction within the system, a far greater amount of CO2 will be released a lot quicker and can saturate smaller enclosed rooms like stock rooms, utility rooms, basements, etc. Most systems are required to have Leak Detection alarms but I don't believe that is always the case in certain situations and regions and if it's like anything else the testing and maintenance of these systems probably don't rank high on somebody's to-do list

Also people suppression system, apparently

I had a fast food job a long time ago... the stuff was always in 2 tanks that I recall

It probably depends on sales volume
