Chapter 1 - Standard Infection Control Precautions (SICPs)
Standard Infection Control Precautions (SICPs), covered in this chapter are to be used by all staff, in all care settings, at all times, for all patients1 whether infection is known to be present or not to ensure the safety of those being cared for, staff and visitors in the care environment.
SICPs are the basic infection prevention and control measures necessary to reduce the risk of transmission of infectious agent from both recognised and unrecognised sources of infection.
Sources of (potential) infection include blood and other body fluids secretions or excretions (excluding sweat), non-intact skin or mucous membranes and any equipment or items in the care environment that could have become contaminated.
The application of SICPs during care delivery is determined by an assessment of risk to and from individuals and includes the task, level of interaction and/or the anticipated level of exposure to blood and/or other body fluids.
To be effective in protecting against infection risks, SICPs must be used continuously by all staff. SICPs implementation monitoring must also be ongoing to ensure compliance with safe practices and to demonstrate ongoing commitment to patient, staff and visitor safety.
Further information on using SICPs for Care at Home can be found at http://www.nes.scot.nhs.uk/education-and-training/by-theme-initiative/healthcare-associated-infections/training-resources/preventing-infection-in-care-@-home.aspx
1The use of the word 'Persons' can be used instead of 'Patient' when using this document in non-healthcare settings.
1.1 Patient Placement/Assessment for infection risk
Patients must be promptly assessed for infection risk on arrival at the care area (if possible, prior to accepting a patient from another care area) and should be continuously reviewed throughout their stay. This assessment should influence placement decisions in accordance with clinical/care need(s).
Patients who may present a cross-infection risk include those:
- With diarrhoea, vomiting, an unexplained rash, fever or respiratory symptoms.
- Known to have been previously positive with a Multi-drug Resistant Organism (MDRO) e.g MRSA, CPE.
- Who have been hospitalised outside Scotland in the last 12 months.
For assessment of infection risk see Section 2: Transmission Based Precautions.
Further information can be found in the patient placement literature review.
1.2 Hand Hygiene
Hand hygiene is considered an important practice in reducing the transmission of infectious agents which cause HAIs.
Hand washing sinks must not be used for the disposal of other liquids. (See Appendix 3 of Pseudomonas Guidance http://www.hps.scot.nhs.uk/resourcedocument.aspx?id=6073)
Before performing hand hygiene:
- expose forearms;
- remove all hand/wrist jewellery (a single, plain metal finger ring is permitted but should be removed (or moved up) during hand hygiene);
- ensure finger nails are clean, short and that artificial nails or nail products are not worn; and
- cover all cuts or abrasions with a waterproof dressing.
To perform hand hygiene:
Alcohol Based Hand Rubs (ABHRs) must be available for staff as near to point of care as possible. Where this is not practical, personal ABHR dispensers should be used.
Perform hand hygiene:
- before touching a patient;
- before clean/aseptic procedures. If ABHR cannot be used then antimicrobial liquid soap should be used;
- after body fluid exposure risk;
- after touching a patient; and
- after touching a patient’s immediate surroundings.
Wash hands with non-antimicrobial liquid soap and water if:
- hands are visibly soiled or dirty;
- caring for patients with vomiting or diarrhoeal illnesses; or
- caring for a patient with a suspected or known gastro-intestinal infection e.g. norovirus or a spore forming organism such as Clostridium difficile.
In all other circumstances use ABHRs for routine hand hygiene during care.
(The video above demonstrating Hand Washing and Drying Technique was produced by NHS Ayrshire and Arran)
Hand wipes should not be used by staff in the hospital/care setting for hand hygiene unless there is no running water available. In this circumstance staff may use hand wipes followed by ABHR and should wash their hands at the first available opportunity.
- Dry hands thoroughly after hand washing using disposable paper towels.
- Use an emollient hand cream during work and when off duty.
- Do not use or provide communal tubs of hand cream in the care setting.
Surgical Hand Antisepsis
Surgical scrubbing/rubbing: (applies to persons undertaking surgical and some invasive procedures)
Perform surgical scrubbing/rubbing before donning sterile theatre garments or at other times e.g. prior to insertion of vascular access devices.
- Remove all hand/wrist jewellery.
- Nail brushes (if used) must only be used for decontamination of nails. Nail picks can be used if nails are visibly dirty.
- Use an antimicrobial liquid soap licensed for surgical scrubbing or an ABHR licensed for surgical rubbing (as specified on the product label).
- ABHR can be used between surgical procedures if licensed for this use.
- For surgical scrubbing technique see Appendix 3.
- For surgical rubbing technique see Appendix 4.
Hand Hygiene posters/leaflets can be found at http://www.washyourhandsofthem.com/home.aspx

- Hand washing
- Indications for hand hygiene
- Skin care
- Surgical hand antisepsis in the clinical setting
- Use of alcohol based hand rub in healthcare settings
(The video above demonstrating Surgical Scrubbing using ABHR was produced by Golden Jubilee National Hospital)
1.3 Respiratory and Cough Hygiene
Respiratory and cough hygiene is designed to minimise the risk of cross-transmission of respiratory illness (pathogens):
- Cover the nose and mouth with a disposable tissue when sneezing, coughing, wiping and blowing the nose.
- Dispose of all used tissues promptly into a waste bin.
- Wash hands with non-antimicrobial liquid soap and warm water after coughing, sneezing, using tissues, or after contact with respiratory secretions or objects contaminated by these secretions.
- Hand wipes should not be used by staff in the hospital/care setting for hand hygiene unless there is no running water available. Staff may use hand wipes followed by ABHR and should wash their hands at the first available opportunity.
- Keep contaminated hands away from the eyes nose and mouth.
Staff should promote respiratory and cough hygiene helping those (e.g. elderly, children) who need assistance with this e.g. providing patients with tissues, plastic bags for used tissues and hand hygiene facilities as necessary.
Further information can be found in the cough etiquette/respiratory hygiene literature review.
1.4 Personal Protective Equipment
Before undertaking any procedure staff should assess any likely exposure and ensure PPE is worn that provides adequate protection against the risks associated with the procedure or task being undertaken.
All PPE should be:
- located close to the point of use;
- stored to prevent contamination in a clean/dry area until required for use (expiry dates must be adhered to);
- single-use only items unless specified by the manufacturer; and
- disposed of after use into the correct waste stream i.e. healthcare waste or domestic waste.
Reusable PPE items, e.g. non-disposable goggles/face shields/visors must have a decontamination schedule with responsibility assigned.
Gloves must be:
- worn when exposure to blood and/or other body fluids is anticipated/likely;2
- changed immediately after each patient and/or following completion of a procedure or task;
- changed if a perforation or puncture is suspected; and
- appropriate for use, fit for purpose and well-fitting to avoid excessive sweating and interference with dexterity.
Double gloving is recommended during some Exposure Prone Procedures (EPPs) e.g. orthopaedic and gynaecological operations or when attending major trauma incidents.
For appropriate glove use and selection see Appendix 5.
Further information can be found in the Gloves literature review.
Aprons must be:
- worn to protect uniform or clothes when contamination is anticipated/likely e.g. when in direct care contact with a patient; and
- changed between patients and/or following completion of a procedure or task.
Full body gowns/Fluid repellent coveralls must be:
- worn when there is a risk of extensive splashing of blood and/or other body fluids e.g. in the operating theatre; and
- changed between patients and immediately after completion of a procedure or task.
Further information can be found in the Aprons/Gowns literature review.
Eye/face protection (including full face visors) must:
- be worn if blood and/or body fluid contamination to the eyes/face is anticipated/likely e.g. by members of the surgical theatre team and always during Aerosol Generating Procedures. Regular corrective spectacles are not considered eye protection.
- not be impeded by accessories such as piercings/false eyelashes.
Further information can be found in the eye/face protection literature review.
Fluid Resistant Type IIR surgical face masks must be:
- worn if splashing or spraying of blood, body fluids, secretions or excretions onto the respiratory mucosa (nose and mouth) is anticipated/likely;
- worn to protect patients from the operator as a source of infection e.g. when performing an epidural or inserting a Central Vascular Catheter (CVC);
- well fitting and fit for purpose (fully covering the mouth and nose) (manufacturers’ instructions must be adhered to ensure effective fit/protection); and
- removed or changed;
- at the end of a procedure/task;
- if the integrity of the mask is breached, e.g. from moisture build-up after extended use or from gross contamination with blood or body fluids; and
- in accordance with specific manufacturers’ instructions.
Further information can be found in the surgical face masks literature review.
Footwear must be:
- able to either withstand machine washing at 40°C or disinfection with a chlorine releasing agent.
- non-slip, clean and well maintained, and support and cover the entire foot to avoid contamination with blood or other body fluids or potential injury from sharps; and
- removed before leaving a care area where dedicated footwear is used e.g. theatre.
Further information can be found in the footwear literature review
Headwear must be:
- worn in theatre settings/clean rooms e.g. Central Decontamination Unit (CDU);
- well fitting and completely cover the hair; and
- changed/disposed of between clinical procedures/tasks or if contaminated with blood and/or body fluids.
For the recommended method of putting on and removing PPE see Appendix 6.
Further information can be found in the headwear literature review
2Scottish National Blood Transfusion Service (SNBTS) adopt practices that differ from those stated in the National Infection Prevention and Control Manual.
1.5 Safe Management of Care Equipment
Care equipment is easily contaminated with blood, other body fluids, secretions, excretions and infectious agents. Consequently it is easy to transfer infectious agents from communal care equipment during care delivery.
Care equipment is classified as either:
- Single-use – equipment which is used once on a single patient and then discarded. Must never be reused even on the same patient. The packaging carries the symbol below.
- Needles and syringes are single use devices. They should never be used for more than one patient or reused to draw up additional medication.
- Never administer medications from a single-dose vial or intravenous (IV) bag to multiple patients.
- Single patient use – equipment which can be reused on the same patient.
- Reusable invasive equipment - used once then decontaminated e.g. surgical instruments.
- Reusable non-invasive equipment (often referred to as communal equipment) - reused on more than one patient following decontamination between each use e.g. commode, patient transfer trolley.
Before using any sterile equipment check that:
- the packaging is intact;
- there are no obvious signs of packaging contamination;and
- the expiry date remains valid.
Decontamination of reusable non-invasive care equipment must be undertaken:
- between each use;
- after blood and/or body fluid contamination;
- at regular predefined intervals as part of an equipment cleaning protocol; and
- before inspection, servicing or repair.
Adhere to manufacturers’ guidance for use and decontamination of all care equipment.
All reusable non-invasive care equipment must be rinsed and dried following decontamination then stored clean and dry.
Decontamination protocols should include responsibility for; frequency of; and method of environmental decontamination.
An equipment decontamination status certificate will be required if any item of equipment is being sent to a third party e.g for inspection, servicing or repair.
Guidance may be required prior to procuring, trialling or lending any reusable non-invasive equipment.
Further information can be found in the management of care equipment literature review.
For how to decontaminate reusable non-invasive care equipment see Appendix 7
1.6 Safe Management of Care Environment
It is the responsibility of the person in charge to ensure that the care environment is safe for practice (this includes environmental cleanliness/maintenance). The person in charge must act if this is deficient.
The care environment must be:
- visibly clean, free from non-essential items and equipment to facilitate effective cleaning;
- well maintained and in a good state of repair; and
- routinely cleaned in accordance with the Health Facilities Scotland (HFS) National Cleaning Specification:
- A fresh solution of general purpose neutral detergent in warm water is recommended for routine cleaning. This should be changed when dirty or at 15 minutes intervals or when changing tasks.
- Routine disinfection of the environment is not recommended. However, 1,000ppm available chlorine should be used routinely on sanitary fittings.
Staff groups should be aware of their environmental cleaning schedules and clear on their specific responsibilities.
Cleaning protocols should include responsibility for; frequency of; and method of environmental decontamination.
Further information can be found in the routine cleaning of the environment in hospital setting literature review
1.7 Safe Management of Linen
- Should be stored in a clean, designated area, preferably an enclosed cupboard.
- If clean linen is not stored in a cupboard then the trolley used for storage must be designated for this purpose and completely covered with an impervious covering that is able to withstand decontamination.
- Clean linen that is deemed unfit for re-use e.g. badly torn, should be disposed of locally or returned to the laundry for disposal.
Linen used during patient transfer
- Any linen used during patient transfer e.g. blankets, should be categorised at the point of destination.
For all used linen (previously known as soiled linen):
- Ensure a laundry receptacle is available as close as possible to the point of use for immediate linen deposit.
- Do not:
- rinse, shake or sort linen on removal from beds/trolleys;
- place used linen on the floor or any other surfaces e.g. a locker/table top;
- re-handle used linen once bagged;
- overfill laundry receptacles; or
- place inappropriate items in the laundry receptacle e.g. used equipment/needles.
For all infectious linen (this mainly applies to healthcare linen) i.e. linen that has been used by a patient who is known or suspected to be infectious and/or linen that is contaminated with blood and/or other body fluids e.g. faeces:
- Place directly into a water-soluble/alginate bag and secure; then place into a plastic bag e.g. clear bag and secure before placing in a laundry receptacle. This applies also to any item(s) heavily soiled and unlikely to be fit for reuse.
- Used and infectious linen bags/receptacles must be tagged e.g. ward/care area and date.
- Store all used/infectious linen in a designated, safe, lockable area whilst awaiting uplift. Uplift schedules must be acceptable to the care area and there should be no build-up of linen receptacles.
Local guidance regarding management of linen may be available.
Further information can be found in the safe management of linen literature review and National Guidance for Safe Management of Linen in NHSScotland Health and Care Environments For laundry services/distribution http://www.hps.scot.nhs.uk/haiic/ic/resourcedetail.aspx?id=1542 .
Further information about linen bagging and tagging can be found in Appendix 8.
1.8 Safe Management of Blood and Body Fluid Spillages
Spillages of blood and other body fluids may transmit blood borne viruses.
Spillages must be decontaminated immediately by staff trained to undertake this safely.
Responsibilities for the decontamination of blood and body fluid spillages should be clear within each area/care setting.
For management of blood and body fluid spillages see Appendix 9.
Further information can be found in the management of blood and body fluid in health and social care settings literature review.
1.9 Safe Disposal of Waste (including sharps)
Scottish Health Technical Note (SHTN) 3: NHSScotland Waste Management Guidance contains the regulatory waste management guidance for NHSScotland including waste classification, segregation, storage, packaging, transport, treatment and disposal.
The Health and Safety (Sharp Instruments in Healthcare) Regulations 2013 outline the regulatory requirements for employers and contractors in the healthcare sector in relation to the safe disposal of sharps.
Categories of waste:
- Healthcare (including clinical) waste – is produced as a direct result of healthcare activities e.g. soiled dressings, sharps.
- Special (or hazardous) waste – arises from the delivery of healthcare in both clinical and non-clinical settings. Special waste includes a range of controlled wastes, defined by legislation, which contain dangerous or hazardous substances e.g. chemicals, pharmaceuticals.
- Domestic waste – must be segregated at source into:
- Dry recyclates (glass, paper and plastics, metals, cardboard).
- Residual waste (any other domestic waste that cannot be recycled).
- Black – Trivial risk:
- Domestic waste or yellow and black stripes (small quantities of hygiene waste).
- Final disposal to Landfill.
- Clear/opaque receptacles may also be used for domestic waste at care area level.
- Orange, Light Blue (laboratory) – Low risk3
- Orange - consists of items which are contaminated or likely to be contaminated with blood and/or body fluids. Final disposal following heat disinfection is to landfill.
- Light Blue – laboratory/microbiological waste that must be autoclaved before disposal via the orange stream.
- Yellow– High risk:
- Waste which poses ethical, highly infectious or contamination risks.
- This includes anatomical and human tissue which is recognisable as body parts, medical devices and sharps waste boxes that have red, purple or blue lids.
- Disposal is by specialist incineration.
- Red – Special waste
- Chemical waste.
For care/residential homes waste disposal may differ from the categories described above and guidance from local contractors will apply. Refer to SEPA guidance http://www.sepa.org.uk/waste.aspx.
Safe waste disposal at care area level:
Always dispose of waste:
- immediately and as close to the point of use as possible; and
- into the correct segregated colour coded UN 3291 approved waste bag (either orange/yellow for healthcare waste or black/clear/opaque for domestic) or container (sharps box).
Liquid waste e.g. blood must be rendered safe by adding a self-setting gel or compound before placing in a healthcare waste bag.
Waste bags must be no more than 3/4 full or more than 4 kgs in weight; and use a ratchet tag/or tape (for healthcare waste bags only) using a ‘swan neck’ to close with the point of origin and date of closure clearly marked on the tape/tag.
Store all waste in a designated, safe, lockable area whilst awaiting uplift. Uplift schedules must be acceptable to the care area and there should be no build-up of waste receptacles.
Sharps boxes must:
- have a dedicated handle;
- have a temporary closure mechanism, which must be employed when the box is not in use;
- be disposed of when the manufacturers’ fill line is reached; and
- be labelled with point of origin and date of closure.
Local guidance regarding management of waste at care level may be available.
Further information can be found in the safe disposal of waste literature review.
3Not required for boards with an on-site incinerator facility. This applies only to NHS Borders.
1.10 Occupational Safety: Prevention and Exposure Management (including sharps)
The Health and Safety (Sharp Instruments in Healthcare) Regulations 2013 outline the regulatory requirements for employers and contractors in the healthcare sector in relation to:
- arrangements for the safe use and disposal of sharps;
- provision of information and training to employees;
- investigations and actions required in response to work related sharps injuries.
Sharps handling must be assessed, kept to a minimum and eliminated if possible with the use of approved safety devices.
Manufacturers’ instructions for safe use and disposal must be followed.
Needles must not be re-sheathed/recapped.4
Always dispose of needles and syringes as 1 unit.
If a safety device is being used safety mechanisms must be deployed before disposal.
A significant occupational exposure is:
- a percutaneous injury e.g. injuries from needles, instruments, bone fragments, or bites which break the skin; and/or
- exposure of broken skin (abrasions, cuts, eczema, etc); and/or
- exposure of mucous membranes including the eye from splashing of blood or other high risk body fluids.
There is a potential risk of transmission of a Blood Borne Virus (BBV) from a significant occupational exposure and staff must understand the actions they should take when a significant occupational exposure incident takes place. There is a legal requirement to report all sharps injuries and near misses to line managers/employers.
For the management of an occupational exposure incident see Appendix 10
Further information can be found in the occupational exposure management (including sharps) literature review.
4 A local risk assessment is required if re-sheathing is undertaken using a safe technique for example anaesthetic administration in dentistry.
