Is 21% Oxygen Harmful?
On an unrelated reason , my local fire dept was at my home last night checking for carbon monoxide. They stated there were no reading of carbon monoxide readings nor were any detectors in the home activated. They then advised that we had 21% oxygen in our home and had to vacate????? Is 21% oxygen what we breath every second of our lives ?

Hi, thanks for posting in the HCM.
I don't think 21% atmospheric oxygen is abnormal. Earth's atmosphere normally contain this percentage of oxygen in the air. The normal carbon dioxide level is 0.04%.
If your in-home atmosphere contains these two gases in the above mentioned percentage, I don't think there is any harm.
Regarding your second question, I can say, the air we breath in has 21% oxygen in it. Rest is occupied by nitrogen mostly and some other gases in trace amount.
Hope you are satisfied with my answer.
