“On 21 August 1986, a limnic eruption at Lake Nyos in northwestern Cameroon killed 1,746 people and 3,500 livestock.[1]
The eruption triggered the sudden release of about 100,000–300,000 tons (1.6 million tons, according to some sources) of carbon dioxide (CO2).[2][3] The gas cloud initially rose at nearly 100 kilometres per hour (62 mph; 28 m/s) and then, being heavier than air, descended onto nearby villages, displacing all the air and suffocating people and livestock within 25 kilometres (16 mi) of the lake.[4][5]”

Your experience with local CO2 pipeline ruptures may vary.
CO2 pipelines? OK. lol
Interesting account - I sort of remember that incident with that gas cloud. So yeah - concentrating it into a pipeline that might leak.... And I’m guessing Paladin2 isn’t talking about an extra 10 to 100 ppm of CO2 in the air as being “toxic”.
