This precision is important for sustaining the usefulness of the biodecontamination process and doesn’t rely on vaporization dependant on ambient place circumstances. Clean sterile air or nitrogen is circulated following decontamination. The H₂O�?vapor breaks down into water and oxygen, lowering residual amounts to below one ppm—safe for operator entry. https://vhpsterilizationofisolato60256.mycoolwiki.com/8540025/vhp_sterilization_an_overview
