The Device Invented to Resuscitate Canaries in Coal Mines (Circa 1896)
- londons_explore 7y agoIts interesting the article says "canaries started to show signs of distress". Humans don't show distress when exposed to carbon monoxide - they just get tired and go to sleep forever. Do birds have a different response?
- detaro 7y agoHumans get symptoms too (feeling tired, nausea, confusion,...), but the symptoms aren't very specific and with higher concentrations the the time between them and loss of control isn't that long. Canaries are more sensitive, so they'll fall silent and pass out quicker. German wikipedia cites ~3000ppm as "headaches within 5-10 minutes, death within 30" for humans, while a "canary falls off its perch after 2.5".
