How Often Should I Reapply Disinfection Coating? Disinfection coating is a clear, odorless, and tasteless process that coats the surface of an instrument. It works primarily as a physical barrier to protect instruments from contamination after treatment by high levels of hydrogen peroxide or ethylene oxide gas. Disinfection coating may also enhance biocidal activity.
Disinfection coating allows instruments to be used aseptically until activated by hydrogen peroxide or ethylene oxide gas during sterilization procedures. After treatment, the maximum shelf life of instruments has not been established but is usually three months or less. The disinfection coating does not protect against the growth of microorganisms on the instrument surface.
Applied in a thin film to hard, smooth surfaces for complete and balanced disinfection that cannot be achieved by simply cleansing with an alcohol wipe. Disinfection Coating offers all of the benefits of coating technology when used as part of a comprehensive approach to surface disinfection.
Both Zwitterionic surfactant-based coatings and bleached-lime/calcium hydroxide coating are generally applied with a spraying machine.
The main reason is that it makes the disinfection coating more stable. With this method, you have to spray several thin applications on one surface, which will result in an even layer without any drop-offs.
Disinfection coating is a physical barrier, not a sterilization agent. It must be activated by hydrogen peroxide or ethylene oxide gas during the sterilization process to provide an effective microbicide. Reapplications of disinfection coatings on instruments do not enhance microbicidal activity, and there is no maximum number of times disinfection coating can be reapplied.
Instruments should be re-coated when the disinfection coating is observed to have been compromised by use or visible residues from previous treatments become apparent on the surface. These conditions usually indicate that a new coat of Disinfection Coating has been consumed and may be directly related to the number of sterilization cycles used in a given period.
Instruments may be coated with disinfection coating immediately before sterilization and packaging for distribution. They should not remain in a dry state for an extended period before use.
NOTE: Disinfection coating is not intended to replace routine and thorough cleaning before use. Always clean instruments thoroughly
Disinfection coating must be reapplied if the coating is damaged or deteriorated if visible residues from previous treatments become apparent on the surface, or when devices have been exposed to chemical and physical abuse. Do not reapply disinfection coating if instrument surfaces are visibly contaminated with blood, tissue particles, bone fragments, dirt, or solidified blood.
Instruments should be re-coated when the disinfection coating is observed to have been compromised by use or visible residues from previous treatments become apparent on the surface. Reapply Disinfection Coating only when necessary, and prevent cross-contamination in areas with proteinaceous materials before detecting protein deposits on instrument surfaces.
