Can terrorist attack with CO or CO2? I know you can purchase CO2 in bulk, what about CO?

Question

I doubt terrorist would rig a bunch of running cars to a buildings air ducts but, is it a possibility in use against buildings, shopping malls, i doubt subways because they have detectors for such gases.

Answer 1

First of all, the amounts of CO or CO2 would be tremendous to have any effect in an area like a mall. Its a dilution factor.

CO2 can be condensed out of the air. CO is a product of combustion and by far the most dangerous. But, then again, its the dilution factor and a ventilation system that exchanges outside air for inside air. The logistics would be incredible.

Answer 2

Well most of the CO detectors are probably dead as the sensors are chemical and only last about 3 years. The CO2 is no problem as the gas is very heavy and the plants if any would absorber a lot of it. CO is very similar and in most cases the only ones in real danger are lien on the floor. CO is not odorless that is a hand down from many years ago when the natural gas had no odor. The CO2 made from gasoline smells different from that made from gas.
CO is very dangerous.

Answer 3

and just what do you think they are going to do with a ton of CO2?
suffocate and entire building of people with it?
attempting to do that would definitely be an act of desparation.
would be something you see in a Spy Vs Spy comic in Mad magazine! LOL

Answer 4

Countries that have used poison gas in warfare have not used CO because it cannot be made in large enough quantity to be an effective weapon.
