Vaporized hydrogen peroxide is used for bio-decontamination in several applications from
healthcare and pharmaceutics to food and beverage industry. Vaporized hydrogen peroxide is
an easy-to-use and eective bio-decontaminating agent that destroys the full spectrum of
biological contaminants including micro-organisms such as bacterial spores, mycobacteria,
and non-enveloped, non-lipid viruses. Bio-decontamination with vaporized hydrogen peroxide
is a low-temperature, environmentally friendly process that leaves no real residues, only water
vapor and oxygen. One of the
benefits also is that the bio-decontamination process can be
validated.

bio-decontamination applications include isolators, transfer hatches,
closed Restricted Access Barrier Systems, and room bio-decontamination (for example, in
hospital environments, cleanrooms, decontamination tents, aircrafts, ships, and shipping
containers).
The bio-decontamination process typically has the following phases:
1. Optional dehumidification, where relative humidity is decreased to a desired level, for
example, by warming the space.
2. Conditioning, where vaporized H

mixture is introduced into the space to be bio-
decontaminated.
3. Decontamination, where H

4. Aeration, where H

is removed from the bio-decontaminated space.
