3. HOSPITAL STERILIZATION
• Sterilization is the complete elimination or destruction of all forms of microbial life
and is accomplished in healthcare facilities.
• We can divide the various departments of the hospital in to these three main
categories on the basis of their cleaning and sterilization.
• Non- Sterile Zone
• Semi-Sterile Zone
• Sterile Zone
4. CLEANING OF HOSPITAL ENVIRONMENT
• Routine cleaning is important to ensure a clean and dust free hospital environment.
• Administrative and office areas with no patient contact require normal domestic
cleaning.
• We can put these areas into non – sterile zone.
5. SEMI-STERILE AREA
• Most patient care areas should be cleaned by wet mopping.
• The use of neutral detergent solution improves the quality of cleaning.
• The frequently touched surface should be physically cleaned with a detergent
solution followed by disinfectant.

6. QUALITY CONTROL NORMS FOR
OPERATION THEATRE ENVIRONMENT
• Modern operating theaters have conventional plenum ventilation( Particles ≥ 5µm
are removed.
• In orthopaedic and other implant surgery, laminar-flow system are used with HEPA
filters ( particle ≥0.3 µm )
• With the use of HEPA filters in Operating Theater ventilation , there is a tendency
to apply clean room technology standards used in industry for Hospital.

10. INTENSIVE CARE UNITS( ICU)
In ICU patients are particularly prone to device related
infections.
They are also exposed to broad spectrum antibiotics and
are sucessptible to multi drug resistant organism.
Method used for sterilization:
1-Hydeogen peroxide vapor
2-UV light decontamination
3- Formaldehyde and kmno4 for fumigation
3- Ultramicofibres which is associated with copper based
biocide can be used for daily cleaning
11. RECOMMENDATION FOR CLEANING AND
DECONTAMINATION
• The hospital staffs should be properly trained regarding the cleaning and decontamination
practices of hospital surfaces.
• The staffs should wear personal prophylactic equipment (PPE),
• Avoid using HLD for environmental surfaces of the hospital and offices. Mopping of the
hospital surfaces should be done using detergent. Table tops and counters should also be
cleaned regularly by detergent only.
• Mopping of high-risk areas such as the intensive care units (ICUs), burn wards, transplant
units, isolation wards, operation theaters (OTs), and dialysis machines should be done using
HLD instead of detergent. Cleaning by vacuum pump and use of high-efficiency particulate
air (HEPA) filters for the exhaust are preferred in these places.
