SYSTEM DRAWINGS:

M-1602 PIPELINE DISTRIBUTION SYSTEM DESIGN The following general information is required to design an MGPS: a. schedule of provision of terminal units; b. design flow rates and pressure requirements at each terminal unit; c. diversified flows for each section of the pipeline system; d. total flow. The definition of “departments”, which may comprise several wards, treatment rooms etc, should be agreed at the project design stage to avoid confusion. Safety The safety of an MGPS is dependent on four basic principles: a. identity; b. adequacy; c. continuity; d. quality of supply. Identity is assured by the use of gas-specific connections throughout the pipeline system, including terminal units, connectors etc, and by the adherence to strict testing and commissioning procedures of the system. Adequacy of supply depends on an accurate assessment of demands and the selection of plant appropriate to the clinical/medical demands on the system. Continuity of supply is achieved by: • the specification of a system that (with the exception of liquid oxygen systems which may include a secondary vessel) has duplicate components; • the provision of a third means of supply for all systems except vacuum; • the provision of alarm systems; and • connection to the emergency power supply system. Surgical air systems are not considered to be life-support systems and therefore duplicate components are not normally required; an emergency/secondary supply is provided. Quality of supply is achieved by the use of gases purchased to the appropriate Ph. Eur. Requirements or produced by plant performing to specific standards, by the maintenance of cleanliness throughout the installation of the system, and by the implementation of the various testing and commissioning procedures. For vacuum systems, the minimum vacuum should not fall below 300 mm Hg at the front of each terminal unit at a design flow of 40 L/min. In virtually all cases, vacuum is used via a suction control device and fluid is collected in suction jars. On wards these are typically of approximately 1 L capacity. In operating rooms, two or four 2–3 L capacity vessels are provided for the suction control regulator. Oxygen is used at a typical flow of 5–6 L/min. Each terminal unit should, however, be capable of passing 10 L/min (at standard temperature and pressure (STP)) at a supply pressure of 400 kPa (nominal), in case nebulisers or other respiratory equipment are used. HTM’s Table 13 contains the formula for arriving at diversified flows. Air is used to provide power for several types of equipment including surgical tools, ventilators and nebulisers. Oxygen should be avoided as a power source because of fire risk and cost, and should not be used where medical air is available, unless specifically recommended by the device manufacturer.



Air should be provided at two different pressures but to the same Ph. Eur. standard: a. a pressure of 400 kPa is required for medical air to drive ventilators and for other respiratory applications; b. a pressure of 700 kPa or higher is required for surgical air to drive surgical tools. A minimum pressure required at terminal units for respiratory use is 370 kPa. Medical air should not be used to supply mechanical services. INSTALLATION/SUPPLY OF EQUIPMENT/ MAINTENANCE The installation of an MGPS should be carried out only by specialist firms registered to BS EN ISO 9001:2000/BS EN ISO 13485:2003 with the scope of registration appropriately defined. MODIFICATIONS Special precautions are required when existing installations are to be modified or extended, to ensure that all sections of the pipeline system remaining in use are not contaminated, and that the supply to patients is not compromised. The section to be modified should be physically isolated from the section in use. Closure of isolating valves is insufficient for this purpose. Where area valve service units (AVSUs) and/or line valve assemblies (LVAs) have been installed, blanking spades should be used. This isolation procedure is not required when work is to be carried out on individual terminal units. Modification of existing systems may be detrimental to the overall performance of the system. In the case of older systems, there may be insufficient capacity to permit the system to operate safely with the flows typically encountered in use today. Any work involving alteration, extension or maintenance work on an existing system should be subject to the permit-to-work procedure. TERMINAL UNITS Terminal unit provision, location of AVSUs, local alarm indicator panels and LVAs are given in Table 11 of HTM. Medical treatment policy is evolutionary, however, and the project team should review requirements for individual schemes. Terminal units should be mounted in positions that result in the shortest practicable routes for flexible connecting assemblies, between the terminal unit and apparatus. Terminal units may be surface- or flush-mounted. They may also be incorporated with electrical services, nurse call systems, televisions, radio and audio services, in proprietary fittings such as medical supply units, wall panel systems and pendant fittings etc. When they are installed within such fittings, it is essential to maintain the concentricity of the terminal unit bezel with the fascia plate aperture; if the installation is highly eccentric, the bezel will bind on the fascia plate and the terminal unit will not function properly.

All terminal units should conform to BS EN 737-1:1998. Terminal units intended for wall mounting where directly connected equipment such as flow meters are to be used must include a non-swivel device. Terminal units intended for installation with the socket axis vertical, for example in certain types of pendant, or where horizontally mounted but intended for use with indirectly connected equipment by means of a flexible connecting assembly, should also have a non-swivel device because flow meters may be attached. Dimensions of probes are given in BS 5682:2005. It is essential that probes be machined from stainless steel. Mounting heights for terminal units should be between 900 mm and 1600 mm above finished floor level (FFL) when installed on walls or similar vertical surfaces – the optimum height for the convenience of users of the medical gas system is 1400 mm. When terminal units are incorporated within a horizontal bedhead service trunking system, which also provides integrated linear lighting for general room and/or patient reading illumination, it should be of a design that does not compromise the convenience of the medical gas facility.



Pressure losses across terminal units should be in accordance with BS EN 737-1:1998. (The standard does not give pressure loss data for surgical air at 350 L/min – but this can be up to 100 kPa when connected via a ceiling NIST (non-interchangeable screw thread) connector and 5 m of hose.) AVSUs

AVSUs should be mounted at a convenient height between 1 m and 1.8 m such that they can be operated comfortably by staff without their needing to stoop or overreach. The order of the location of individual valves in an array should follow that for terminal units, for example: O2, N2O and/or N2O/O2, MA, SA, VAC, He/O2. If the array exceeds 1 m in height from top to bottom, it may be preferable to arrange them in two columns. Care must be taken to ensure that AVSUs cannot be obscured by opening doors etc. The minimum height of 1 m is the optimum. In critical care areas where dual circuits are installed, it may be necessary to reduce this to 800 mm to avoid an excessive number of columns of AVSUs. LOCAL ALARM INDICATOR PANELS The placing of local alarm indicators should be such that they are readily visible by staff; notices, partitioning, screens etc should not obscure them. The mounting height should be such that in the event of an audible alarm sounding, staff can activate the “mute” switch without overreaching and be a maximum 1.8 m above finished floor level. LVAs LVAs should be installed at branches from risers, branches from main runs, and where pipelines pass into or out of a building.

SPECIFIC LABELLING REQUIREMENTS All AVSUs should be labelled to identify the individual rooms, sets of terminal units etc. controlled. They should be provided with flow direction arrows. In critical care areas where dual circuits and/or subdivision of circuitry occur, terminal units require to be identified as associated with the specific AVSU.

APPENDIX A - O&M REQUIREMENTS

1.0 Introduction

The purpose of operating and maintenance manuals is to provide information which will alert those who are responsible for the installation after handover, of the key health and safety risks that will need to be dealt with during subsequent construction work, including maintenance, cleaning, repair, alteration, refurbishment and demolition.

The provision of Operating and Maintenance manuals that form part of the overall project health and safety plan is a requirement of the Construction (Design and Management) Regulations 1994, SI1994 No. 3140. Significant hazards or risks identified during the design and construction and particularly those considered to be unusual, or where specific procedures or precautions will need to be taken to ensure that the works are carried out safely, must be clearly identified.

All sections of the manuals are to produced using: ‐

‐ 4 ‘D’ ring presentation ring binders (A4 50mm or 65mm).

‐ Clear reinforced A4 pockets for drawings and documents, open at top.

‐ Section dividers, suitable coloured PVC/polypropylene etc.

Documents, text etc. are to be provided as follows: ‐

‐ A4 size, four hole punched to suit binders – loose, not stapled or bound.

‐ Originals or first generation copies.

‐ Project specific information only will be accepted.

‐ All pages to be project titled, dated, numbered, with reference and identification of originator.

‐ Contents list and sub‐contents list to be provided as necessary.

‐ All documents too thick to be hole punched are to be presented in clear reinforced pockets.

‐ Provide electronic versions of all drawings, schedules and text on a CD, in AutoCAD and Microsoft Word Format for future use and amendment by others.

Draft copies of the manuals must be delivered to the Design Engineer’s office for inspection at least 2 weeks prior to handover. Every effort will be made to return them with comments marked in red ink within 48 hours so all comments can be incorporated prior to handover.
