Study Notes
Environmental Cleaning & Disinfection in Healthcare
- Routine cleaning is insufficient for disinfecting operating rooms; terminal cleaning is required.
- Phenol is a common disinfectant in healthcare settings.
- Quaternary ammonium compounds have a dwell time of 2 to 10 minutes.
- Hydrogen peroxide is dangerous to mix with other cleaning chemicals.
- EPA-approved disinfectants are recommended for healthcare facilities.

- The proper cleaning sequence goes from clean to dirty areas to prevent cross-contamination.
- Chlorine compounds are effective, but corrosive and require careful handling.
- Terminal cleaning is thorough disinfection of patient rooms or high-risk areas after patient discharge.
- Alcohol-based disinfectants are used to sanitize small surfaces and hands.
- Pathogens spread in healthcare facilities can be prevented by regularly disinfecting high-touch surfaces.
- Alcohol-based disinfectants have a recommended dwell time of 0.5 to 2 minutes.
- Routine cleaning is done daily, while terminal cleaning occurs after patient discharge.
- A 5000 ppm bleach solution is used for disinfecting areas contaminated with blood spills.
- Environmental cleaning should follow standardized protocols and procedures to ensure effective infection control.
- Hydrogen peroxide is a powerful oxidizing agent used for surface and equipment disinfection in healthcare settings.
- The main components of environmental cleaning in infection control are routine cleaning, disinfection, and adherence to protocols.
- Dwell time is the required contact time for disinfectants to effectively kill microorganisms.
- Non-critical items like furniture and floors require routine disinfection to maintain low microbial loads.
- Overuse of disinfectants can lead to the development of microbial resistance, making them harder to eliminate.
- Personal Protective Equipment (PPE) protects cleaning staff from pathogens and harmful chemicals during environmental cleaning.
- Mop heads should be regularly wrung out to avoid spreading contaminants and immersed in rinse water every few strokes.
- Cleaning removes visible dirt and organic material, while disinfection kills or inactivates microorganisms.
- Alcohol-based disinfectants act quickly, evaporate without residue, and are effective against most bacteria and viruses, making them ideal for high-touch surfaces.
- Microfiber cloths trap more dirt and bacteria, resulting in better cleaning and reduced cross-contamination risk.
