6.3 Hydrogen Peroxide
Biodecontamination
Figure 6-1. X10 Biodecontamination Unit
The X10 Biodecontamination Unit (see Figure 6-1) provides a simple
and reliable method for Biodecontaminating pre-cleaned, dry sealable
Enclosures (refer to SECTION 2.1, TERMS AND DEFINITIONS).
Effective use of H2O2 vapor for Biodecontamination requires adequate
concentration and exposure time.
The X10 Biodecontamination Unit typically uses a closed loop process
(refer to SECTION 3, OPERATING INSTRUCTIONS) utilizing air as a carrier
to deliver Vaprox 59 Hydrogen Peroxide Sterilant vapor to the
exposed surfaces inside a pre-cleaned, dry, sealed Enclosure (refer
to SECTION 2.1, TERMS AND DEFINITIONS). This closed loop process
allows the Biodecontamination process to take place at atmospheric
conditions. Because Biodecontamination relies only on the contact of
Sterilant with exposed surfaces, the transfer of heat and moisture
required by steam processes is not necessary.
H2O2 vapor is continuously injected for the required exposure time to
achieve Biodecontamination. The Sterilant evacuated from the
Enclosure in a closed loop operation is catalytically converted into
water vapor and oxygen. .
6.4 Biodecontamination
Cycle
The properly installed X10 Biodecontamination Unit outside the
Enclosure (refer to
SECTION 2.1, TERMS AND DEFINITIONS
) uses STERIS’s
VHP
®
process technology. This process uses hydrogen peroxide vapor
as a broad-spectrum antimicrobial without condensation of active
ingredient onto surfaces. This non-condensation feature provides
additional benefit of a wide range of material compatibility.
In practice, an aqueous solution of 59% (Vaprox 59 Hydrogen Peroxide
Sterilant) hydrogen peroxide vapor is atomized and a high velocity air
stream disperses it throughout Enclosure. Relative humidity and
temperature sensor measurements ensure the vapor does not condense
on internal Enclosure surfaces.
NOTE: Refer to the Vaprox 59 Hydrogen Peroxide Sterilant package
label for additional information and Application instructions.

Cabinet phase.
5. After pre-heating cabinet to 88°F (31°C), Dehumidification phase
starts and air circulates through desiccant to dehumidify
Enclosure to 15% RH.
NOTE: During this time the liquid Sterilant is primed into the
injection lines (approximately two minutes for priming).
6. After 15% RH setpoint is reached, Enclosure is heated to 88°F
(31°C).
7. Once setpoint is reached, heater cap is heated to set value.
8. Condition phase (Sterilant injection) begins. Biodecontamination
Unit generates hydrogen peroxide vapor and circulates Sterilant
throughout Enclosure at set injection rate to build concentration to
> 400 PPM.
9. Biodecontamination phase follows for preset time.
