As mentioned earlier, our air is mostly nitrogen, so yeah I don't think that alone triggers anything.
Instead it detects compounds, or mixtures of otherwise common elements that should not appear in specific proportions. The warning about Gojo and latex gloves is probably because latex and petroleum (distillates of which are present in Gojo) are the primary ingredients for napalm.
