Sanitizing and disinfecting household and office equipment requires differentiated approaches based on the level of infection risk. In the home, the goal is to sanitize and remove pathogens, while in office settings, high-level disinfection or sterilization is necessary to eliminate germs and pathogenic spores.
1. Household Equipment (Sanitation and Disinfection)
Household cleaning aims to remove dirt, while sanitization targets bacteria and viruses.
Common Surfaces and Objects: Use 70% ethyl alcohol or diluted bleach (sodium hypochlorite), which are excellent for bathroom fixtures, handles, and floors.
Kitchen Utensils: Dishwasher at 65-70°C, or very hot water and detergent.
Delicate Surfaces: Microfiber cloths dampened with water and a neutral detergent.
Electronic Devices: Cloths dampened (not wet) with isopropyl alcohol.
2. Outpatient Equipment (Disinfection and Sterilization)
The outpatient protocol requires a precise sequence: cleaning, rinsing, disinfection, and final disinfection.
Cleaning (pre-disinfection): Removal of visible soil and organic material.
Disinfection of instruments: Use of alcohol (60-90%), quaternary ammonium compounds, or chlorhexidine and cetrimide solutions.
Sterilization: Primary method for critical devices, usually in a steam autoclave (121°C or 134°C) or with ethylene oxide.
Non-critical medical equipment (stethoscopes, thermometers): Disinfection with 70% alcohol or specific disinfectants for medical-surgical devices.
3. Key Differences in Methods
Sanitization: Specific action to reduce microorganisms, often synonymous with thorough cleaning with chemicals.
Disinfection: Destruction of most pathogenic microorganisms, but not necessarily spores, on inert surfaces.
Sterilization: Complete destruction of all microbial forms, including spores.
4. Operational Precautions
PPE: Always wear gloves and appropriate protection.
Safety: Unplug electrical equipment before cleaning.
Contact Times: Follow the times indicated on the disinfectant label to ensure effectiveness.
Cleaning Order: Proceed from the cleanest to the dirtiest areas, and from high to low surfaces.
Note: Before using any product, check the manufacturer's instructions to avoid damaging materials.
