What Solution Should Touu Use to Sterlize Contaminated Items

Every healthcare facility should have written protocols to guide routine general cleaning and ensure that all areas of the environment are regularly cleaned to a satisfactory standard. Staff undertaking cleaning should follow agreed protocols and have access to adequate resources and equipment to achieve the required standard of cleaning. COSHH regulations should always be adhered to and staff should use appropriate personal protective equipment (PPE) to protect themselves at all times.

Cleaning

Cleaning with warm water and detergent is a process that removes visual dirt and contamination and in most cases is effective for decontaminating both equipment and the environment.

However in certain situations e.g. during an outbreak, increased incidence of infection or in the case of Clostridium difficile infection, surfaces and equipment require both cleaning and disinfection.

Disinfection

Disinfection is a process that reduces the number of microorganisms to a level at which they do not present a risk to patients or clients. It is only effective if surfaces and equipment have been cleaned thoroughly with detergent and water beforehand. Warm water and detergent should be used to clean hard surfaces followed by disinfection with 1000ppm (0.1%) chlorine releasing agent/hypochlorite solution or chlorine dioxide solution (diluted, and with a contact time, as per manufactures' instructions). The specific disinfectant to be used will be specified in the local cleaning/disinfection policy or procedure. The hypochlorite or chlorine dioxide solution will kill both bacteria and viruses provided it is used as per manufactures' instructions. Hypochlorite solutions are corrosive and it is recommended that the solution is rinsed off commodes, mattresses and stainless steel surfaces with warm water at the end of the process. Some chlorine dioxide solutions do not need to be rinsed off.

Cleaning and disinfection of the environment

Routine General Cleaning?

Routine cleaning of the environment should be undertaken at least daily. Thorough cleaning with neutral detergent and water is commonly used. If soiling (with blood and/or bodily fluids) is evident, then general cleaning should be followed with a disinfectant clean - using a chlorine releasing product/sodium hypochlorite or a chlorine dioxide solution. If using a hypochlorite solution the area should then be rinsed and dried although this is not required with some chlorine dioxide solutions.Always ensure that surfaces that are being disinfected are compatible with the product being used.

Enhanced Cleaning?

During an outbreak of infection or an unusual increase in the incidence of a particular organism, enhanced routine cleaning (minimum twice daily) is recommended. This will entail cleaning/disinfecting the environment including frequently touched surfaces such as bed tables, bed rails, the arms of chairs, sinks, call bells, door handles and push plates, and any area/piece of equipment that may potentially be contaminated. Depending on the type of outbreak in the healthcare facility, certain areas will require more frequent cleaning and disinfection, e.g. sanitary areas during an outbreak of gastrointestinal infection.

Terminal Cleaning?

Terminal cleaning is the thorough cleaning/disinfection of all surfaces including floors and re-useable equipment either within the whole healthcare facility or within an individual ward/department/unit. This may be required in the following circumstances:

• Following an outbreak or increased incidence of infection
• Following discharge, transfer or death of a patient who has had a known infection
• Following isolation/contact precaution nursing of a patient

A terminal clean will be advised following discussion and agreement between the Infection Prevention & Control Team and the nurse or manager in charge of the ward/unit/facility. The terminal clean should not commence until the relevant room/area has been fully vacated.

Note: The cleaning schedule for the facility should clearly advise which member of staff is responsible for cleaning different areas of the room/areas to be included in the terminal clean.

Note: In addition to the above, some facilities/organisations employ the use of other technologies such as steam or vaporised hydrogen peroxide when doing terminal cleans. This is an additional step in the cleaning process but should not replace the physical decontamination of the environment/equipment with detergent & water and disinfectant.

Terminal cleaning procedure:

• Gather all equipment required for the terminal clean at the point of use e.g. mop bucket, mop, disposable colour coded cloths, disposable roll, yellow clinical waste bags & tags, alginate & red bags, wet floor sign, vacuum cleaner fitted with a HEPA filter.
• Don Personal Protective Equipment (PPE), i.e. disposable apron and gloves, before entering the room, discard all disposables in the room/bed space/unit (e.g. hand towels, magazines, bottles, toilet rolls, etc.) All materials must be disposed of as clinical waste.
• Prepare cleaning/disinfecting solutions in a container (dilution as per manufacturer's instruction). Do not mix chemicals and only use a cleaning product provided by your employer.
• Ventilation of the area/room being cleaned must be adequate; if there is no window, the door should be left open when applying hypochlorite/chlorine dioxide solutions.
• Disinfectant solutions should be used as per Manufacturer's instructions, particularly the contact time. Also the Control of Substances Hazardous to Health (COSHH) regulations must be adhered to when using chemical disinfectants.
• After cleaning, rinse with water (if rinsing is required) before drying. In particular it is important to rinse chlorine containing solutions from stainless steel surfaces to prevent corrosion.
• Use disposable cloths/paper roll for cleaning during the terminal clean. Where available and appropriate, use disposable mop heads. After use, these should be disposed into a clinical waste bag before leaving the area/room.
• Ensure that PPE is changed when moving from one room/area to another and dispose into a clinical waste bag.
• Always decontaminate your hands after removing and disposing of PPE.
• Avoid leaving and re-entering the area until the terminal clean is fully completed.
