What a gas: Leaking carbon-dioxide tank shuts Chinatown McDonald's, nearby streets

Firefighters are at Washington and Kneeland streets, where CO2 is leaking from a 100-gallon tank in the basement of the McDonald's at the corner. Police are diverting traffic away from the area.

It is extremely unlikely that a McDonalds has a 100 gallon CO2 tank.

I mean, it could be a 100 gallon tank - but that doesn't give any real indication of the amount of CO2 in that tank as you can push more molecules (n) into a fixed volume (v) and raise the pressure (p) at a fixed temp (t).

Could always be liquid CO2, as it often is supplied as liquid in a tank instead of a gas. And 100 gallons doesn't seem like that much, the biologists at work have two ~60 gallon tanks of liquid CO2 hooked up to their incubators, and we're a pretty small research site.

the SIlver Line buses I saw on Bolyston Street east of Charles on my way into work earlier.

All these diversions and all this for a soda machine's CO2 supply? Is this for real? Something like 83% of the air we're breathing is CO2.

What gives? Why's traffic need to be diverted? Someone give me a chemistry lesson, please.

Like, say, a basement, CO2 can kill.

As for the traffic, it was more to keep motorists from running over the fire hoses firefighters set up when they first arrived and because there were a bunch of firetrucks blocking traffic, anyway.

CO2 is measured in parts per billion when discussing climate change.

Less than 0.03% of the air we breathe.

And, as Adam points out, it can be lethal as it is a heavier gas than N2 and O2 and can cause suffocation by excluding oxygen in confined spaces.

"Something like 83% of the air we're breathing is CO2."

If we're rounding, the % would be Zero. Not 83%, but 0%.

Gives them a chance to try on their hazmat suits.

Where is Al Gore, Greenpeace, and the EPA? Isn't the escape of CO2 into the atmosphere a fracking global catastrophe needing immediate attention? We need to stop all carbonation of water and soft drinks!

BTW, the movie Cool It is showing this week on premium cable.

Because if not, I'd be glad to explained to you how closed systems work.

Or, if you're serious,...you could just help us all out and stop breathing to keep the CO2 levels down.
