3 1. Introduction 1.1. Ventilation is used extensively in healthcare premises to closely control the environment and air movement of the space that it serves. This is for both the comfort of occupants in buildings and to contain, control and reduce hazards to patients, staff and visitors from airborne contaminants including, dust and harmful micro-organisms This Policy sets out the detailed requirements for the maintenance and safe operation of all air conditioning and ventilation plant. These will be maintained so that they do not present a risk to persons either in the vicinity of the plant, in areas served by the plant, or a statutory compliance risk to the Royal Cornwall Hospitals NHS Trust (referred to as the Trust ) This version supersedes any previous versions of this document. 2. Purpose of this Policy 2.1. This Policy requires that all ventilation and air conditioning equipment is installed, inspected, serviced and maintained in accordance with all Statutory Instruments, NHS Guidelines and Health Technical Memorandums (HTM) to ensure that such equipment does not pose a health or operational risk to either, staff, patients or visitors. 3. Scope 3.1. This Policy applies to all staff, service users and contractors associated with the Trust. Those persons with defined responsibilities should read this policy, and where applicable, read and understand the ventilation procedures manual This Policy covers all maintenance activities on ventilation and air conditioning plant within the Trust, and any sites which the Trust is responsible for the maintenance of ventilation equipment. This will include, but not limited to, local room extraction plants up to full air handling and conditioning systems This policy document and associated ventilation procedures manual cannot anticipate all eventualities, therefore professional judgement should be used to identify the appropriate course of action needed The on-going risk management process will enable those involved, namely, the Responsible Person Ventilation, Authorised Person Ventilation, Competent Persons and Infection Prevention Control Team to identify the level of vulnerability and risks posed to individuals; including service users, staff members and visitors, thereby ensure appropriate action will be taken. 4.

Infection Prevention Control Team The Infection Prevention Control Team will nominate a point of contact to advise on the monitoring of microbiological performance of the air conditioning and ventilation systems Trust Members of Staff All Trust staff members are responsible for reporting defects and faults with any ventilation systems, as they occur, via the Estates Department Helpdesk. 6. Standards and Practice 6.1. Design and Installation All new ventilation and air conditioning equipment will be designed, installed and commissioned by suitably qualified Engineers and Tradespersons. They will be compliant with the requirements of Health Technical Memorandum (HTM) 03 and other legislation; such as, the Health and Safety at Work Act 1974, the Control of Substances Hazardous to Health Regulations 2002, the HSE Control of Legionella Approved Code Of Practice L8, Regulatory Fire Reform Order and specific requirements under the Medicines Act Copies of all HTM s can be found online at the Government Library Webpage Such a system must be appropriate for the area for which it was designed and is only installed where absolutely necessary and by agreement with the Infection Prevention Control Team Information for all new equipment, concerning its installation, designed mode of operation together with full details of maintenance procedures, shall be provided as part of the commissioning process In areas undergoing refurbishment, advice will be sought from the Infection Prevention Control Team to determine the requirements of the existing ventilation and air conditioning systems. Where systems will not meet current HTM 03 standards, equipment will be upgraded or replaced Standards Operational Standards applied during the design and installation of ventilation and air condition systems will not to be reduced during the operation and life of the equipment. This will be evidenced through the use of planned maintenance records held within the Estates Department. Assessment of the suitability of older ventilation systems shall be made with the assistance of the Authorising Engineer (Ventilation) and the Infection Prevention Control Team Maintenance All service and maintenance procedures shall conform to the principles set out in Specialised Ventilation for Healthcare premises HTM 03-01, and the Approved Code of Practice on the Prevention of Control of Legionella published by the Health & Safety Commission and The control of Legionella, hygiene, safe hot water, cold water and drinking water systems (HTM) and any subsequent legislation or guidelines.

6 6.4. Operational Procedures The following operational procedures shall be defined: Differentiation between critical and non-critical plant. The safe plant start, run, set-back, restart and stop procedures, including minimum run up times to achieve desired operating conditions Frost protection sequence Arrangements for protecting and mothballing the plant if unused for extended periods, and to prevent it becoming a possible source of infection. Schedules of routine maintenance activities. Maintenance and routine inspections records shall be maintained. Details of the above and any specific risk assessments will be kept in the operational procedures manual within the Estates Department Information Maintenance and routine inspections records shall be maintained for ventilation plant, and kept within the Estates Department electronic database For the safety of contractors and maintenance staff the following information shall be provided adjacent to the plant to which it refers: a) General information regarding the intended operation of the plant together with a schematic diagram of the equipment and its distribution system. b) Information concerning the purpose of the plant and details of those departments and/or personnel served by the plant and who should be informed prior to switching off or carrying out maintenance activities. c) Information required for the safety of the personnel carrying out the service and maintenance activities These procedures set out a frequency of tests, appropriate recording sheets and guidance. All maintenance will conform to the principles set out in HTM03-01 and HTM Maintenance Tasks Ventilation System Plant Inspections (Quarterly, 6 Monthly and Annual) All ventilation systems, as a minimum, will be subject to: An annual visual inspection to ensure that the system is still required The fire containment (Damper) has not been breached The general condition of the system is fit for purpose The system is operating as designed Page 6 of 23

7 For each inspection a simple check sheet will be used. (Noncritical ventilation systems (Appendix D) and critical systems (Appendix E)) The record sheets include space for recording chlorination of chiller batteries and humidifiers. (Detail of this procedure can be found within the Legionella prevention procedures). The periodicity of inspections is set out in Appendix B Annual Verification for Critical Ventilation Systems All critical ventilation systems will be subject to an annual verification to ensure: The ventilation system should achieve not less than 75% of the design air-change rate given in Appendix H, or its original design parameters. Old design parameters based on plant age can be obtained from HTM 2025, Microbiological Commissioning and Monitoring of Operating Theatre Suites (Lidwell. 1972), IHVE Guide (1965 edition) The pressure regime should achieve not less than 75% of the design value given in Appendix 2 of Part A, or its original design parameters, and the pressure gradient relationships with regards to surrounding areas must be maintained. Old design parameters based on plant age can be obtained from HTM 2025, Microbiological Commissioning and Monitoring of Operating Theatre Suites (Lidwell. 1972),IHVE Guide (1965 edition) The sound levels quoted in HTM 03 Table 2 are maximum permissible levels and should not be exceeded. Measurements should be made using at least a Type 2 sound meter fitted with a muff. Its accuracy should be checked using a calibration sound source before use Further guidance from HTM03-01 Part B paragraphs 4.19 to 4.28 are followed as appropriate for: Vertical ultra-clean operating theatres Horizontal ultra-clean operating theatres Category 3 and 4 laboratories Pharmacy aseptic suites Sterile Service packing and inspection rooms LEV s Filter Changing The routine changing of filters should be carried out either when the manometer across the filters reaches the designed change limit or on a time basis, provided the designed manometer maximum pressure differential is not exceeded. Suitable records of filter changes will be kept Quarterly Chlorination of Chilled water Circuits Chilled water refrigeration units must be inspected, cleaned and chlorinated every 3 months. Details of this process are contained within the Legionella procedures; this work may be contracted out, any works that are contracted out will be under a detailed specification under Page 7 of 23

8 the Trusts contracting arrangement, as a minimum, the contractor must provide the following information: Make Model Serial no. Location Area served Filter checked Filter cleaned Filter replaced Hypochlorite cleaning of cooling coil Hypochlorite cleaning of drain pan Hypochlorite cleaning of condensate drain Date/time/engineers signature Portable Air Conditioning Units Portable air conditioning units are available from the Estates Stores or hired-in when required during excessive building temperatures. They typically incorporate internal recirculation air filters and a drainage system to remove condensate from the cooling coil. The Infection Prevention Control Team must be consulted before these types of units are deployed All portable units will be inspected and cleaned every week that they remain in use. Records of this service and inspection will be kept. The units must be inspected and thoroughly cleaned before being placed into use. Units that are to be used in areas containing immunecompromised patients will, unless new, need to have a bacterial fumigation before being deployed. Units that have been used in isolation rooms or areas containing symptomatic patients will be fumigated before being used in other locations or returned to store or the hirer Air conditioning units employing an internal water reservoir and wick to promote evaporative cooling will not be used within the Trust; any of these units found in circulation will be immediately removed and destroyed Description of Ventilation Systems and Classification Ventilation systems within the Trust are divided into two categories; critical and non-critical. The criterion below defines those ventilation systems which are considered critical: Operating theatres of any type, including rooms used for interventional investigations (for example catheter laboratories) Patient isolation facility of any type Critical care, intensive treatment or high-dependency unit Neonatal unit Category 3 or 4 laboratory or room Pharmacy aseptic suite Page 8 of 23

9 Inspection and packing room in a sterile services department, sterile endoscope re-processing rooms MRI, CAT and other types of emerging imaging technologies that require particularly stable environmental conditions to remain within calibration Any system classified as an LEV system under the COSHH Regulations (some of these systems may be subject to local management contracts within the department) Any other system that clearly meets the definition The loss of service from such a system would seriously degrade the ability of the premises to deliver optimal healthcare The Head of Estates is responsible for ensuring that an inventory of critical and non-critical ventilation systems is kept up to date. This inventory will be discussed and signed off by the Infection Prevention Control Team. The importance of this definition is to determine the maintenance regime. Sample sheet Appendix A Inspection, Condition Assessment and Operational Parameters The Trust has a range of ventilation plants of varying age and to meet all the criteria of HTM03 will take significant time. To ensure that replacement funding resources are correctly prioritised, an initial assessment of condition and compliance will be made. The systems will be graded into the categories indicated within HTM03; this grading system gives guidance on the best course of action for each grade. The funding requirement for each system will then be added to the Estates Backlog Maintenance Risk Weighted Capital Bid Register as detailed in the planned and reactive maintenance policy. This process will be repeated on a five yearly basis or when changes are to be made. The sheet for initial assessment is attached at Appendix C Mothballing Plant It may be necessary to stop the use of plant but maintain it in an operational condition for an extended or undetermined period of time. For this scenario refer to the procedures manual for details To re-instate the plant, a commissioning procedure will need to be written for the specific plant; guidance on this procedure should be sought from HTM03-01, the Authorised Person (Ventilation) and the Infection Prevention Control Team Mothballing Split Air Conditioning It may be necessary to mothball split air conditioning plant, in this configuration the written scheme in the procedures manual will be adhered to To re-instate the split air conditioning plant, a commissioning procedure will need to be written for the specific air conditioning unit; guidance on this procedure will be sought from HTM03-01, the AP (V) and the Infection Prevention Control Team.

10 Frost Protection Trust ventilation systems will have frost protection in the event of very low outside air temperatures or plant faults. The protection works by detecting the air temperature after the frost/fog coil; should the air temperature be equal to or below 3 0 C, the plant will stop and the frost/fog coil will open fully. The plant will then not start again until manually reset; this reset will only happen once it is operationally safe to re-start the plant and no risk of coil failure exists Fire Dampers Fire dampers are fitted in the ventilation system where ducts pass through fire walls and barriers. There are two general types of dampers: Fusible link spring loaded dampers fitted to older buildings, which require heat from a fire to activate and will not stop smoke penetration prior to the fusible link activating the damper. Motor driven spring loaded fire dampers activated by the fire alarm system fitted to new buildings and are designed to stop smoke on fire alarm activation. These dampers will be subject to periodic servicing and testing at a frequency specified in Appendix B and appropriate records kept Ventilation Supply and Extract Grill Cleaning The ventilation supply and extract grills are to be cleaned regularly to ensure that dust does not build up. The periodicity of this will be the same as High level dusting as detailed in the National Cleaning Standards for the NHS. This is a routine part of the Domestic Services function; details of these standards are contained in Standard Operating Procedure (SOP) for Hotel Services Department. The Estates Department will ensure that each supply and extract grill, within patient critical care areas, are disassembled and deep cleaned annually. 7. Dissemination and Implementation 7.1. The policy will be disseminated to all Divisional Directors and Directorate Managers and via the Documents Library Copies will also be made available to Estates Department, Contractors, Estates Intranet Site, Project Co [PFI Services Providers] (via Contracts office) Authorised Person and Competent Person will be trained in line with this policy. Training will take place at specialist training facilities. Page 10 of 23
