Disinfection is normally undertaken on an infrequent basis, during periodic maintenance checks or after a public health event, such as the suspected carriage of an infectious passenger. Disinfection is usually preceded by cleaning of the affected area.
- All activities are to be carried out in a safe way.
- Do not touch body fluids or anything that was used by the sick person including bed covers, plate, cup and utensils without wearing appropriate gear.
- One of the residents (if they want) and he / she must be properly wearing the recommended personal protective equipment (PPE).
- Disinfection team comprising of at least three (3) individuals i.e. the supervisor and two (2) assisting personnel.
- Nevertheless, one (1) extra personal PPE should always be taken along.
Do’s and Don’ts of wearing PPE:
- Do change gloves if yours get torn or are very dirty; wash your hands before putting on new gloves.
- Do wash your hands thoroughly with soap and water or an alcohol based hand rub after, removing PPE.
- Don’t touch your face or adjust your PPE with contaminated gloves.
- Don’t wash or reuse disposable gloves
Apparatus & Machine Disinfection
There are several ways to disinfect equipment, and the products available at the health-care facility should be used. Safe methods of disinfection include:
- Heat for heat-resistant equipment that can withstand high temperature (e.g. 80 °C); such equipment can be disinfected using a washer–disinfector;
- if a washer or pasteurizer is not available, use a high-end or commercial dishwasher with a “sanitize” feature that can reach 70 °C ;
- For plastic equipment that may not tolerate 80 °C and for equipment that may be damaged by boiling, or in the absence of the equipment described above, we use chemical disinfection
- If using chemical disinfection, rinse with sterile or clean water (i.e. water boiled for 5 minutes and cooled). Sterile water is preferred for rinsing off residual liquid chemical disinfectant from a respiratory device that has been chemically disinfected for reuse, because tap or distilled water may harbor microorganisms that can cause pneumonia. However, when rinsing with sterile water is not feasible, instead, rinse with tap water or filtered water
