High standards of cleanliness and safety have always been critically important to hospitals,
Cleaning, the physical removal of organic material or soil from objects, is usually done by using water with or without detergents. Generally, cleaning is designed to remove rather than to kill microorganisms. Sterilization, on the other hand, is the destruction of all forms of microbial life; it is carried out in the hospital with steam under pressure, liquid or gaseous chemicals, or dry heat. Disinfection, defined as the intermediate measures between physical cleaning and sterilization, is carried out with pasteurization or chemical germicides.
Although microorganisms are a normal contaminant of walls, floors, and other surfaces, these environmental surfaces rarely are associated with transmission of infections to patients or personnel. Therefore, extraordinary attempts to disinfect or sterilize these environmental surfaces are rarely indicated. However, routine cleaning and removal of soil are recommended. Recommendations for cleaning in the rooms of patients on isolation precautions have been published.
CONTROL MEASURES
Cleaning schedules and methods vary according to the area of the hospital, type of surface to be cleaned, and the amount and type of soil present. Horizontal surfaces (for example, bedside tables and hard-surfaced flooring) in patient-care areas are usually cleaned on a regular basis, where soiling or spills occur, and when a patient is discharged. Cleaning of walls, blinds, and curtains is recommended only if they are visibly soiled. Disinfectant fogging is an unsatisfactory method of decontaminating air and surfaces and is not recommended.
A ward surface which is physically clean and dry is unlikely to represent an appreciable infection risk. Wet surfaces and equipment are more likely to encourage micro-organisms and to spread potential infection.
Before starting a shift, cleaning equipment should always be clean and dry. Cleaning solutions should be freshly prepared and discarded straight after use .
It is the responsibility of staff to follow cleaning procedures which reduce the risk of hospital acquired infection. To achieve this, a few straight forward rules need to be followed.
Personal Hygiene
A good standard of personal hygiene is necessary in as hospital environment. Clean overalls must be worn at all the times, long hair tied back and an overall tidy appearance maintained.
Hand Washing and Drying
A good hand washing and drying technique is essential to protect staff, patients and others from the spread of bacteria.
Hand should be washed and thoroughly dried:
Colour Coding
Cloths and Mark the handles of mops with coloured tape
After use mop heads should be removed, bagged in a net bag, cloths bagged and sent to the hospital laundry, or washed in the domestic service washing machine and dried in a tumble drier.
Protective Clothing
Protective clothing must be worn when carrying out the following procedure:
All waste must be kept covered and segregated according to type:
Equipment:
The feeding of animals or birds is forbidden unless these are official pets belonging to the ward.
To discourage pests food should be kept covered and refrigerated. Any sightings or evidence of pests should be reported immediately to a supervisor.

INTRODUCTION
Although soiled linen has been identified as a source of large numbers of pathogenic microorganisms, the risk of actual disease transmission appears negligible. Rather than rigid rules and regulations, hygienic and common sense storage and processing of clean and soiled linen are recommended.
CONTROL MEASURES
Soiled linen can be transported in the hospital by cart or chute. Bagging linen is indicated if chutes are used, since improperly designed chutes can be a means of spreading microorganisms throughout the hospital . Recommendations for handling soiled linen from patients on isolation precautions have been published .
Soiled linen may or may not be sorted in the laundry before being loaded into washer/extractor units. Sorting before washing protects both machinery and linen from the effects of objects in the linen and reduces the potential for recontamination of clean linen that sorting after washing requires. Sorting after washing minimizes the direct exposure of laundry personnel to infective material in the soiled linen and reduces airborne microbial contamination in the laundry . Protective apparel and appropriate ventilation can minimize these exposures.
The microbicidal action of the normal laundering process is affected by several physical and chemical factors . Although dilution is not a microbicidal mechanism, it is responsible for the removal of significant quantities of microorganisms. Soaps or detergents loosen soil and also have some microbicidal properties. Hot water provides an effective means of destroying microorganisms, and a temperature of at least 71°C (160°F) for a minimum of 25 minutes is commonly recommended for hot-water washing. Chlorine bleach provides an extra margin of safety. A total available chlorine residual of 50-150ppm is usually achieved during the bleach cycle. The last action performed during the washing process is the addition of a mild acid to neutralize any alkalinity in the water supply, soap, or detergent. The rapid shift in pH from approximately 12 to 5 also may tend to inactivate some microorganisms.
Recent studies have shown that a satisfactory reduction of microbial contamination can be achieved at lower water temperatures of 22-50°C when the cycling of the washer, the wash formula, and the amount of chlorine bleach are carefully monitored and controlled (6, 7). Instead of the microbicidal action of hot water, low temperature laundry cycles rely heavily on the presence of bleach to reduce levels of microbial contamination. Regardless of whether hot or cold water is used for washing, the temperatures reached in drying and especially during ironing provide additional significant microbicidal action.
If hot water is used, linen should be washed with a detergent in water at least 71°C (160°F) for 25 minutes
If low temperature (<70°C) laundry cycles are used, chemicals suitable for low-temperature washing at proper use concentration should be used
