The contamination of the environment (surfaces in patient care areas and
mobile medical equipment) play a major role in the transmission of
potential pathogens.
TERMINOLOGIES & DEFINITIONS:
• Antisepsis: Chemical destruction of vegetative pathogens on living tissue.
• Degerming: Mechanical removal of microbes from limited area.
• Sanitization: Lowering microbial counts on eating and drinking utensils to safe levels.
• Sepsis: Bacterial contamination
• Asepsis: Absence of significant contamination
• Aseptic technique: To minimizes contamination.
• Cleaning: Physical removal of foreign material, e.g., dust, soil, organic material such as blood, secretions,
excretions and microorganisms. It is accomplished with water, detergents and mechanical action.
• Decontamination: The removal of disease-producing microorganisms to leave an item safe for further

handling
• Sterilization: Complete elimination or destruction of all forms of microbial life accomplished in healthcare
facilities by either physical or chemical processes.
• Disinfection: Cleaning some or all pathogenic organisms from an article of which may cause infection.
A perfect disinfectant should offer complete and full sterilization, without harming other forms of life,
inexpensive, and non-corrosive.
Unfortunately ideal disinfectants do not exist.
• High level disinfectants: Destroy vegetative bacteria, mycobacteria, fungi, enveloped (lipid) and
nonenveloped (non lipid) viruses and bacterial spores but not necessarily all bacterial spores.
• Intermediate level disinfectants: Kill vegetative bacteria, most viruses and most fungi but not the bacterial
spores.
• Low level disinfectants: Kill most vegetative bacteria and some fungi as well as enveloped (lipid) viruses
(e.g., hepatitis B, C, hantavirus, and HIV). Low level disinfectants do not kill mycobacteria or bacterial
spores. Low level disinfectants are typically used to clean environmental surfaces.

SPAULDING CLASSIFICATION THREE DEVICE CATEGORIES FOR DISINFECTION AND
STERILIZATION:
• Critical Device enters sterile tissue or vasculature, therefore pose a high risk of infection if contaminated
with microorganisms: Require: Sterilization.
• Semi-critical Device comes in contact with mucous membranes or skin that is not intact, therefore pose a
moderate risk of infection if contaminated with microorganisms: Require: High Level Disinfection.
• Non-critical Device comes in contact with intact skin but not with mucous membranes, therefore, pose little
to no risk of infection if contaminated with microorganisms: Require: Disinfection.
MANAGEMENT OF BLOOD AND BODY FLUID SPILL:
TOOLS OF SPILLAGE KIT:-
1. Protective clothing, gloves, gowns, masks and goggle.
2. Tissue papers (Roll paper towels)
3. Forceps for removal of broken glass or other sharps.
4. Container of Sodium Hypochlorite (Clorox/Bleach) or Presept, Haz Tabs.
5. Biohazard disposal bag for infectious waste.
6. Measuring jar
CHLORINE-RELEASING AGENTS:
Fall into two groups:
1. Sodium dichloroisocyanurate (NaDCC), e.g. Presept, Haz Tabs
NaDCC is recommended for spillages. It is less resistant than hypochlorite to organic matter, less corrosive, and has
a longer shelf life, as it is manufactured as tablets or granules.
2. Sodium hypochlorites (NaOCl), e.g. Clorox / Household bleach.

HOW TO CLEAN BLOOD AND BODY FLUIDS SPILL:
1 Place “Wet Floor” sign near the area of spill.
2. Wear protective clothing and gloves.
3. Put on goggles if splashing is likely.
4. Put on shoe cover to protect shoes if they are likely to become contaminated with the
blood spill.
5. If broken glass or any other sharp object is involved, use forceps to pick up and
throw into a sharp container before any cleaning or disinfecting is ever attempted.
6. Cover spill with paper towels, pure Clorox solution 1:10 dilution over spill starting
from periphery leave for 3-5 minutes. This will ensure ample Contact Time for
disinfection. Then wipe all the blood or body fluid from the surface.
7. Again pour or spray the disinfectant 1:10 dilution bleach solution on the area of spill and leave it for 3-5
minutes. This will ensure ample Contact Time for disinfection.
8. Wiped clean with paper towels.
9. Discard all contaminated paper towels into the infectious yellow bag.
10. Dispose all disposable PPE into yellow infectious waste bag.
11. Dispose yellow plastic bag into infectious waste container.
12. Wash hands with antiseptic detergent.
13. Replace and replenish supplies in the “Spill Kit”
CLEANING BLOOD AND BODY FLUID STAINS:
Wear gloves and others PPE as needed.
Clean the items with detergent and water.
Make Clorox solution (100ml of Clorox in 900ml water/5000 - 6000ppm available Chlorine) in spray bottle and do
heavy spray so that it can take 5 minutes to air dry than clean it.

MANAGEMENT OF OTHER BODY FLUID SPILLS (VOMIT, URINE, FECES):
Wear disposable gloves and apron.
Use disposable paper towels, to mop up spillage.
Dispose of paper towels into clinical waste bag.
Wash area with detergent and water.
After washing one can disinfect area with Clorox solution (40-50 ml of Clorox in 1 Liter water 2500-2700ppm
available Chlorine).
Discard protective apparel into clinical waste bag.
Wash and dry hands thoroughly.
ENVIRONMENTAL DECONTAMINATION:
• Cleaning MUST precede decontamination
• Disinfectant is ineffective if any organic matter present.
• Use mechanical force
– Scrubbing
– Brushing
– Flush with water
• Wipe nonporous surfaces with sponge or wet cloth.
• Allow to dry.
CENTER FOR DISEASE CONTROL [CDC] RECOMMENDED DILUTIONS FOR DISINFECTION
(HOW TO MAKE CLOROX/BLEACH SOLUTION):
Clorox solution must always be freshly prepared and use within 4-8 hours.
1. 100 ml Clorox + 900 ml water = (1:10 dilution/5000-6000 parts per million (ppm) available Chlorine)
2. 40-50 ml Clorox + 1 Liter water = (2500-2700 ppm available Chlorine).
3. Clorox/bleach solution for sanitizing cooking and eating utensils 15 ml (1 Tablespoon) in 4 liter Water = 200 ppm
(must not exceed 200 parts per million available chlorine).
The bleach solution must be applied by spraying, soaking or scrubbing. Let air dry (contact time at least one minute
4. Clorox/bleach solution for sanitizing fruits and raw vegetables 7.5 ml (1 ½ teaspoon) in 4 liter of water = 100 ppm
(must not exceed 100 parts per million available chlorine). After washing dip them for 15 minutes than wash again
with filtered water.

HOW TO MOP FLOOR
Use a mop or bucket system with a floor cleaner solution, beginning in the far corner of the area, under the bed and
then moving toward the bathroom and the door.
Mop the floor in 1-2 meter square sections.
Mop edges with straight strokes, and then continue working from side to side in a backwards direction, using a
figure-of-eight pattern on the remainder of the section, turning the mop frequently.
The floor should be fairly dry on completion.
HOW TO CLEAN AND DISINFECT BATHROOM
• Wash with water and detergent.
• Make Clorox/bleach sol (40-50 ml Clorox + 1 liter water)
• Disinfect all precleaned hard, nonporous bathroom surfaces.
• Start with the highest surface (like the mirror) and leave the toilet for last.
• Ensure that all surfaces, including the sink area, mirrors, grab bars and shower fixtures, are thoroughly
disinfected.
• Disinfect and clean toilet exterior, toilet seat surface, and outer of bowl.
• For inner bowel use 250ml pure bleach contact time 2 min.
• Ensure all surfaces stay wet.

BATHROOM CLEANING PROTOCAL
It is usually best to start with the highest surface (often the mirror) and leave the toilet for last. Clean and disinfect
all hard, nonporous surfaces:
• Mirror, sink area, and grab bars, shower fixtures, toilet exterior, toilet seat surface and outer and inner bowl.
CLEAN AND DISINFECT ISOLATION ROOM
• Using a clean mop, mop the entire floor surface, working your way from the far corner back to the entrance.
• Visually inspect the room and ensure all surfaces have been cleaned and disinfected.
• Then disinfect any cleaning equipment (like mop handles) before returning to the cleaning cart.
• Remove PPE and put in a yellow trash bag prior to leaving the room.
• Wash your hands.
• Return with clean linens and make bed.

Cleaning Levels for Different Clinic Areas
It depend on Infection Control risk assessment of that areas
Low-Risk Areas:
These areas are usually not contaminated with blood or body fluids or with associated infectious
microorganisms so the risk of infection is minimal.
Routine cleaning- the kind of cleaning you would do in your home – is usually good enough for these
areas.
Clean these areas with a mop dampened with detergent and water.
These functional areas included:
1) Administrative areas
2) Waiting rooms
3) Non-sterile supply areas
4) Medical records
5) Engineering workshop
6) Central store
7) Library
8) Conference and Meeting area
9) Staff Change facilities (Staff lounge)

Intermediate (Moderate) Risk Areas:
These are areas used for the care of patients who are not obviously infectious and not highly susceptible.
These areas are cleaned by procedures that control dust, such as damp mopping with detergent cleaners.
Dry sweeping or vacuum cleaners are not recommended.
The use of detergent solution improves the quality of cleaning.
This functional areas includes:
1) Patient Wards
2) Out Patient Department
3) Physiotherapy
4) Pharmacy
5) Laboratories
6) Mortuary
7) Radiology
8) Accommodation (Housing)
9) Employee Health Clinic
10) Cardiology
High Risk Areas:
1) CSSD (Central sterilization and supply department)
2) Emergency Department (ER)
3) Catering facilities (includes all kitchen and cafeteria)
4) Day surgery unit
5) Treatment room.
6) Maternity Ward
7) Pedia Surgery Ward

Very High Risk Areas:
In these areas there is a greater potential pathogen contamination with infectious materials and more of a
concern about potential infection transmission to both patient and clinic staff.
These areas must be cleaned with care using a cleaning solution and separate cleaning equipment; disinfectant
detergent solutions are used as needed, according to hospital policy.
1) Isolation Room
2) Intensive Care Unit (ICU/PICU)
3) Operating Room
4) Neonatal Care unit (NICU and Nursery)
5) Pharmacy IV Preparation room
6) Delivery Room
7) Immuno-compromised patients areas

INFECTION CONTROL PROCEDURES FOR IMAGING CENTERS AND HOSPITAL RADIOLOGY DEPARTMENTS
The cleanliness of imaging centers and hospital radiology departments is crucial for reducing the spread of MRSA and other
acquired infections. The following are 11 simple procedures to implement that can prevent the spread of these infections.
1. Have a written infectious control policy to include MRI cleaning procedures as well as the cleaning schedule and have it
posted throughout the center.
2. Implement a mandatory hand washing / hand sanitizing procedure between patient exams for technologists and any others
who come into contact with patients.
3. Clean the MRI tables, inside the bore of the magnet and any other items that come into contact with a patient. Infection control
experts recommend this be done between each patient.
4. Clean all pads and positioners with an approved disinfectant. Infection control experts recommend cleaning after each patient.
5. Periodically inspect the pads with a magnifying glass, particularly at the seams, to identify fraying or tearing. If present, the
pads should be replaced.
6. Regularly check all padding material with an ultraviolet (black) light and make sure that any biological material detected on
the pads can be removed.
7. Replace damaged or contaminated pads with new pads incorporating permanent antimicrobial agents.
8. Use pillows with a waterproof covering that is designed to be surface wiped. Replace pillows when their barrier is
compromised.
9. Promptly remove body fluids, and then surface disinfect all contaminated areas.
10. If a patient has an open wound or any history of MRSA/other infection:
a. Gloves and gowns should be worn by all staff coming in contact with the patient. These barriers must be removed before
touching other areas not coming in contact with the patient, i.e. door knobs, scanner console, computer terminals, etc.
b. The table and all the pads should be completely cleaned with disinfectant before the next patient is scanned, if it is not already
being performed between every patient. For patients with any known infectious process add 10-15 minutes onto the scheduled
scan time to assure there is enough time to thoroughly clean the room and all the pads.
11. All furniture should be periodically cleaned. Ideal surfaces are those that are waterproof and wipe-able. Infection control
experts recommend this be done between each patient.
Disinfectant Used: Bleach solution 1:10 dilution (100ml bleach in 900ml water) wipes can be use or EPA approved use
disinfectant allowed by infection control dept
