Critical Sterile body tissue or cavity

Sterilization

In Alberta, heat-tolerant critical devices must be steam sterilized

Inactivates:

  • spores
  • protozoa with cysts
  • mycobacteria
  • non-enveloped viruses
  • fungi
  • vegetative bacteria
  • enveloped viruses
  • Steam Sterilization
  • Ethylene Oxide
  • Hydrogen peroxide gas plasma
  • Vapourized Hydrogen peroxide
  • Hydrogen peroxide gas
  • Liquid paracetic acid
  • Ozone
Semi-critical Mucous membranes or non-intact skin

High Level disinfection (HLD) at a minimum; devices should be sterilized if possible.

Steam sterilization is preferred for heat tolerant devices.

Inactivates:

  • Mycobacteria
  • non-enveloped viruses
  • fungi
  • vegetative bacteria
  • enveloped viruses
  • Glutaraldehyde > 2%
  • Ortho-phthaldehyde 0.55%
  • Accelerated hydrogen peroxide > 7%
  • Peracetic acid
  • Pasteurization
  • Thermal HLD in a washer-disinfector with a validated terminal HLD cycle (some makes and models)
Non-critical Intact skin or no direct patient contact

Intermediate or low-level disinfection

Intermediate level disinfectants inactivate:

  • some non-enveloped viruses
  • possibly TB
  • fungi
  • vegetative bacteria
  • enveloped viruses

Low level disinfection inactivates:

  • fungi
  • vegetative bacteria
  • enveloped viruses

Intermediate level disinfectants

  • Alcohol 70%-90%
  • Sodium hypochlorite (bleach)
  • Phenolics
  • Accelerated hydrogen peroxide

Low level disinfectants

  • Quaternary ammonium compounds (Quats)
