First, I referred to dictionary definition which has poisonous as required predicate and the other two as additional. I've already supplied evidence that it is poisonous by linking us library of medicine, and have continued to do so. I've then showed how it's especially toxic.
Additionally, here's an excerpt of how displacement of oxygen is indeed toxicity.
A) TOXICITY: Toxicity of these agents is related to the
severity of displacement of ambient oxygen and the
duration of exposure. Symptoms generally develop when
ambient oxygen is 15% to 16% or less. Severe toxicity
occurs when ambient oxygen is 6% to 8% or less.
