in enclosed environment, leaked co2 can not escape and concentration will rise.

about the 5% toxicity, the detail is in the provided link, very interesting article.

It is the dose that kill, any substance can be toxic if give the proper amount, so as dihydrogen oxide, a poisonous deadly substance.
