See. Comparative evaluation of the microbicidal activity of low-temperature sterilization technology of carriers sterilized by various low-temperature sterilization technologies, Table 12. After cleaning, disinfect with an appropriate disinfectant on. Use low-temperature sterilization technologies (e.g., EtO, hydrogen peroxide gas plasma) for reprocessing critical patient-care equipment that is heat or moisture sensitive. If the user selects exposure conditions that differ from those on the EPA-registered product label, the user assumes liability from any injuries resulting from off-label use and is potentially subject to enforcement action under FIFRA. Flush and brush all accessible channels to remove all organic (e.g., blood, tissue) and other residue. Critical items that have been sterilized by the peracetic acid immersion process must be used immediately (i.e., items are not completely protected from contamination, making long-term storage unacceptable). If the spill contains large amounts of blood or body fluids, clean the visible matter with disposable absorbent material, and discard the contaminated materials in appropriate, labeled containment. Adhere to the FDA enforcement document for single-use devices reprocessed by hospitals. Additionally, diluted household bleach solutions (at least 1000ppm sodium hypochlorite) can be used if appropriate for the surface. Clean and, at a minimum, high-level disinfect heat-sensitive semicritical items. Disinfect protected surfaces at the end of the day or if visibly soiled. This is small enough to be affordable and to ensure that the solution will be used before it degrades, but large enough that it will last a family for approximately one month. The easiest way to find a product on this list is to enter the first two sets of its EPA registration number into the search bar above the list of products. However, multiple scientific studies have demonstrated the efficacy of hospital disinfectants against pathogens with a contact time of at least 1 minute. In addition, after each use, sterilize dental instruments that are not intended to penetrate oral soft tissue or bone (e.g., amalgam condensers, air-water syringes) but that might contact oral tissues and are heat-tolerant, although classified as semicritical. easy to operate, effective cleaning and provide a healthy environment for you and your family. Use a high-level disinfectant at the FDA-cleared exposure time. Areas unoccupied for 7 or more days need only routine cleaning. If additional spore tests remain positive, consider the items nonsterile and recall and reprocess the items from the implicated load(s). When performing care in the home, clean and disinfect reusable objects that touch mucous membranes (e.g., tracheostomy tubes) by immersing these objects in a 1:50 dilution of 5.25%-6.15% sodium hypochlorite (household bleach) (3 minutes), 70% isopropyl alcohol (5 minutes), or 3% hydrogen peroxide (30 minutes) because the home environment is, in most instances, safer than either hospital or ambulatory care settings because person-to-person transmission is less likely. If environmental microbiologic testing is conducted, use standard microbiologic techniques. Do not use flash sterilization for convenience, as an alternative to purchasing additional instrument sets, or to save time. Use standard sterilization and disinfection procedures for patient-care equipment (as recommended in this guideline), because these procedures are adequate to sterilize or disinfect instruments or devices contaminated with blood or other body fluids from persons infected with bloodborne pathogens or emerging pathogens, with the exception of prions. prevent common sources of extrinsic contamination of germicides (e.g., container contamination or surface contamination of the healthcare environment where the germicide are prepared and/or used). Disinfection by Healthcare Personnel in Ambulatory Care and Home Care, 12. If a lower concentration of bleach is desired, the EPA standard disinfection rate for hypochlorite products is 600 ppm for 10 minutes. Exclude healthcare workers with weeping dermatitis of hands from direct contact with patient-care equipment. Wear disposable gloves to clean and disinfect. Clean medical devices as soon as practical after use (e.g., at the point of use) because soiled materials become dried onto the instruments. No changes in these procedures for cleaning, disinfecting, or sterilizing are necessary for removing bloodborne and emerging pathogens other than prions. Prepare and package items to be sterilized so that sterility can be achieved and maintained to the point of use.
