Abstract

The paper reviews the background of the most recent addition to NFPA’s piped gas systems and discusses when the use of Instrument Air might be appropriate. Also reviewed are the rules for the application. Design guidance is provided to allow a system to be sized and implemented.

Pneumatic power and Medicine

Medical facilities are very familiar with compressed air. A typical facility uses any number of individual air systems for power and control. These are as diverse as the laundry compressor for running the washers and dryers, a sterilizer compressor for the autoclaves and decontamination systems in central sterile supply and the HVAC compressor for the pneumatic controls in the air conditioning system.

Given how familiar hospitals are with compressed air, it seems odd that most North American hospitals of any size supply nitrogen into the operating rooms to run surgical tools - a task easily within the capabilities of an appropriate compressed air system.

Compressed air systems require only occasional maintenance, the air is of course free, and there is no management required. By comparison, the nitrogen system is an unending hassle. The nitrogen is in cylinders or containers which must be purchased, inventoried, and changed. Since hustling the cylinders or containers is labor intensive, there is always an overhead in costs and labor associated with its use.

Although the nitrogen system could be used for many purposes per the NFPA standard, the nitrogen gas is relatively expensive so it is not wise to use it for all the applications for which it might otherwise be appropriate. This leaves a quandary when the facility wants pneumatic power in places like the morgue or central sterile supply. Often the unsatisfactory solution is to install separate local systems, which is expensive and increases the maintenance burden.

Compressed air was in fact the original choice when gas - powered tools first came into the operating room, and only in North America was compressed air supplanted by Nitrogen. The reason for this decision is obscured by time, but most likely derives from difficulties with the quality of the air available at the time. Piped air was typically wet, often oily and sometimes dirty, none of which is good for high speed turbine tools. Nitrogen was the driest, cleanest gas they could easily substitute, so it became the gas of choice. Over time, primarily through received knowledge, it acquired the patina of a de facto standard. In fact, Nitrogen for tools has never been required by any


published standard. Nevertheless, Engineers continue even today to design, and facilities continue to install, nitrogen systems for the driving of surgical tools.

In most of the world, compressed air never left the O.R. In the United Kingdom for instance, it is common to install a “7 bar” or “13 bar” surgical air system specifically for driving tools alongside the “4 bar” medical air for treating patients.

There is a vestigial holdover from the use of compressed air for surgical tools in use in North America even today. Surgical tool hoses are still often fitted with a quick connect fitting on the end called a “Schræder” connector - originally manufactured by the Schræder Automotive Division, and used in garages to run their air-powered tools (the historic origin of our elegant surgical tools is not medical, but industrial).

Oddly, although the pipelines changed from air to nitrogen, Schraeder never did make the change. Even today the version of that connector in most common use is stamped “Air” - Schræder itself never made a nitrogen-specific connector, and only very recently have their successor companies created one.

Although Nitrogen systems have become the general standard, there have always been a small number of North American facilities willing to question this. These facilities have installed air systems to drive tools, following their own instincts in light of an absence of guidance in the NFPA or CSA standards. The trend has accelerated somewhat in the last decade, and in the 2002 edition NFPA for the first time included guidance on these systems. Although that might make it seem to be something new, in truth it is actually a return to something very old.

When the Instrument Air system first appeared in the 2002 NFPA 99, there was no Instrument Air terminal unit, and thus no outlets, controls or hoses were available. This was a problem which prevented many facilities from seriously looking at the Instrument Air option. In 2005, the Compressed Gas Association resolved this with the assignment of the CGA 2080 connection to Instrument Air. The only remaining hurdle therefore is the lack of design guidance, which this publication should help address.

Why Change?

There are two reasons to consider an Instrument Air system, and it is important to note that neither is specifically medical. In fact, from the medical standpoint, there is very little to choose between Instrument Air and nitrogen. Both will drive the tools, both (as contemplated by NFPA 99) have similar dryness, cleanliness, and operating pressures. Except for the costs involved, there is no reason a facility could not simply continue to use nitrogen.

So the most compelling reason to consider an Instrument Air system over a Nitrogen system is dollars and cents. The cost of operating a nitrogen system can be surprisingly high, depending on the amount of nitrogen used. Nitrogen sources imply three particular costs:

1. The cost of the gas itself.

2. The cost of the demurrage (rental of the cylinders).

3. The management cost, including the labor involved in hustling the cylinders from the dock to the manifold, attaching and detaching them, and moving the empties back to the dock, plus the management involved in keeping track of cylinder inventories and reordering).

While it is possible to reduce these costs in many cases by using cryogenic liquid in place of gas cylinders, the costs are never completely eliminated, and the installation of a large cryogenic source system may be problematic in other ways.

Generally speaking, an Instrument Air system is going to be more expensive to purchase than a similar capacity manifold or bulk liquid system. However, the Instrument Air itself is less costly on a volume to volume basis, so the Instrument Air system will pay for itself over time. Exactly when the crossover will occur will vary. In some cases, the crossover may be so far out that an Instrument Air system would be a questionable investment. In other cases the payback is so quick that Instrument Air would be worth retrofitting even where a nitrogen system is already in place. In the next chapter entitled “Dollars and Cents”, we give some guidance on how to calculate the crossover point for your facility.

The other reason for considering Instrument Air is the variety of applications for which it can be used. NFPA has continuously sought to keep medical gas systems separate from all other systems and to ensure that the medical gases are not compromised by use for other purposes. NFPA 99 2005 5.1.3.4.2 states “Central supply systems for oxygen, medical air, nitrous oxide, carbon dioxide and all other patient medical gases shall not be piped to, or used for, any purpose except patient care application”. The practical effect of this prohibition is found in the Annex A.5.1.3.4.2 “Prohibited uses of medical gases include fueling torches, blowing down or drying any equipment such as lab equipment endoscopy or scopes, or any other purposes. Also prohibited is using the oxygen or medical air to raise, lower or otherwise operate booms or other devices…”.

Certain of these prohibitions are controversial, but the difficulty they cause can be illustrated. Consider endosurgical areas or central sterile supply. Here, a gas source is desirable to blow out or dry instruments during


cleaning and sterilization. Medical Air cannot be used for this purpose, so the only acceptable alternative has been to install nitrogen. Aside from the cost of nitrogen, this use implies releasing quantities of Nitrogen into the room. Although Nitrogen is itself non-toxic, the release of too much nitrogen will dilute or displace the oxygen in the air and can cause asphyxiation. Nitrogen is therefore not ideal for use in workspace applications such as this, whereas Instrument Air is very suitable.

Applications for Instrument Air are discussed in NFPA 99 5.1.3.8.2.1: “Instrument Air shall be permitted to be used for any medical support purpose (e.g. to operate tools, air driven booms, pendants or similar applications) and (if appropriate to the procedures) to be used in laboratories.”

Whereas Medical Air is and Nitrogen may be prohibited from or undesirable in certain applications, Instrument Air may be used for any of them.

The simple conclusion is that Instrument Air offers a very worthwhile design option. It is not for every facility, because in some it will not offer benefits sufficient to justify the additional up-front costs. But in our studies to date, we are surprised how often and at how low a nitrogen usage we can justify these systems purely on the money saved. Our experience suggests it is an option every facility (including facilities already using nitrogen) should at least examine.

Dollars and Cents

A decision to use an Instrument Air system will hinge on the payback for most facilities. This can be calculated with reasonable accuracy if a few questions can be answered. Clearly, a facility which has some history with an existing nitrogen system will be at an advantage when collecting many of these answers, but even while a project is only in planning one can make a satisfactory estimate. Detail 4 is a listing of the data required. Once you have obtained this data, your BeaconMedaes Sales Consultant has a pre configured spreadsheet which they can use to help you calculate the relative costs and system payback.

NFPA Rules for Instrument Air

The requirements for Instrument Air sources are found in the NFPA 99 under 5.1.3.8, and a few other requirements are found throughout the document.

Instrument Air and nitrogen under the standard are meant to be opposite sides of the same coin. Indeed, a simple guiding principle for working with these systems is that if in doubt, do what you would have done for Nitrogen, and you will probably have done the right thing.

The one place where an Instrument Air system is unique is in the design of the source. Instrument Air source equipment is unique in it’s form, permitted options and operating requirements. An overall view of the components of an Instrument Air source under NFPA 99 are shown in Detail 5 & 6.

Detail 5 : Instrument Air Source System configurations (Per NFPA 99 )

The particular aspects unique to Instrument Air can be summarized:

1. Compressor Type: A compressor used for Instrument Air may be of any type which can produce a pressure greater than 200 psig. Instrument Air compressors do not have to be oilless or oilfree (unlike compressors for Medical Air) but may include lubricated types. This is because the high pressure required makes lubrication inescapable, and since Instrument Air is not breathed by the patient or mixed with oxygen, any oil (should it enter the system) is less hazardous.

The extraordinary pressure requirement comes from the need to ensure that the system can emulate the traditional nitrogen system, which may operate as high as 185 psig. 185 psig is the pressure at which the Instrument Air pipeline system is designed to operate. Clearly, a compressor with a top pressure of 175 psig will not be able to achieve this requirement.

2. Specific Filtration and Purification: Although a lubricated compressor is permitted, oil is not permitted in the system. Instrument Air sources must have coalescing filters to remove liquid oil and activated carbon absorbers to eliminate vapor and gaseous oil. A particulate filter is also required with a nominal pore size of 0.01µ.

3. Dry to -40°: Recall that a major reason for the historic

transition to nitrogen was wet air. In applications like tool drive, the dryness of the air is particularly significant, as the rapid expansion of air in the tools can produce adiabatic cooling which can condense moisture where it would otherwise never appear. Therefore, unlike medical air, Instrument Air must be dried to a nominal -40° dew point. This will necessitate desiccant dryers in virtually all cases.

This combination of filters and dryers is intended to produce air which will comply with or exceed the specifications of the Instrument Society of America standard S-7.0.01 Quality Standard for Instrument Air.

4. A secondary or backup system. Unlike other medical gas systems, failure of an Instrument Air system is unlikely to be fatal. Nevertheless, the system is critical to any number of procedures, and if the procedure was suddenly terminated the patient(s) could be at risk. Thus a backup, just like any other medical gas system, is required.

Unlike other systems however, the requirement for that backup is much less stringent. Uniquely, an Instrument Air compressor may include a redundant compressor(s) (similar to that required for Medical air) or it may be seconded by a bank of cylinders sufficient for one hour’s operation (a hybrid configuration).

The allowance for a cylinder secondary offers a much less

expensive option for installing smaller systems, and yet does not greatly reduce the operational safety of the system overall if properly alarmed.

Where this cylinder secondary is applied, there is a special allowance in the standard for placing the cylinder header with the Instrument Air compressor itself. This is an exception to the general rule that cylinders are not permitted to be in the same room with compressors or pumps. It applies only to the active header used to back up an Instrument Air compressor. There is no exception for loose cylinders, even if those are intended for the Instrument Air system, so these must be stored in an appropriate room just like all other medical gas cylinders.

Although Instrument Air systems are clearly intended to be compressor driven (otherwise the operating economies will be lost) it is possible to use a standard medical gas style manifold to source an Instrument Air system as well.

5. The distribution system for Instrument Air will typically be similar to that for Nitrogen, but given it’s many potential uses, it may also be significantly more complex. The actual design will of course depend on the facility’s convenience and preferences. Some options are illustrated in Details 8-10.

6. Outlets for Instrument Air must be non interchangeable with other medical gases. It is not appropriate to use medical air outlets or nitrogen outlets in an Instrument Air system, even if they are relabelled. NFPA has three requirements for any outlet:

a. Each outlet for a specific gas must be provided with an outlet not interchangeable with any outlet for another gas.

b. That when a single gas is operated at multiple pressures, the outlet for each pressure be non interchangeable with the outlet for another pressure.

c. That when an outlet is operated at pressures greater than 80 psig, that the outlet be of the DISS (threaded) type, or include a pressure interlock to prevent the hose from flying out of the outlet when disengaged.

These requirements taken together mean that the ideal Instrument Air outlet is the CGA DISS outlet, and this is the outlet BeaconMedæs recommends for all Instrument Air terminals, hoses and accessories.

7. Instrument Air has it’s own color coding and labelling (see Detail 7.1). The color for Instrument Air is a red ground with white lettering, and the abbreviation is “Instrument Air”. Standard pressure is 160-185 psig through the pipeline, and the nonstandard pressure rules will apply for Instrument Air systems operated at different pressures (see NFPA 99 5.1.5.15, 5.1.11.1, 5.1.11.2.2, 5.1.11.3.2).

8. Alarm requirements for Instrument Air are similar in most respects to those for any medical gas system (local, master and area alarms are all required). However, the unique configurations permitted for the source do imply

some specific alarm signals (see Detail 7.2).

Design and Installation

Instrument Air systems are designed in the same manner as any medical gas system (please refer to the BeaconMedæs Medical Gas Design Guide, Chapter 9 for Medical Support Gases for detailed instructions).

The design of an Instrument Air system and the selection of the source requires knowing all the many applications which it is intended to serve. The first step in the design

must be to determine what all the applications demand in terms of pressure and flow, and then to determine the size of compressor required. An Instrument Air system will fall into either (and in some cases both) of two types. Systems for use at high pressures (e.g. to substitute for Nitrogen) will be designed as would Nitrogen systems. Systems for exclusively lower pressure applications (e.g. for labs, central sterile supply, etc.) can be laid out like any other pressure gas system.

If it is the desire of the facility to supply both high and

low pressure applications from the same source of supply, there are some considerations which will affect the design. NFPA 99 5.1.3.4.6 discourages the construction of what is termed a distributed pressure system in favor of two distinct pipeline systems divided at the source and separately provided with all the necessary controls (see Detail 8). Nevertheless, the language is sufficiently open, and the application sufficiently unique that some degree of local pressure control may be permissible.

If local pressure control is desired, the design of the system would roughly follow the current practice in the

O.R. There, the pipeline delivers the maximum pressure to ensure the best possible flow rate, and Instrument Air control panels are placed where necessary for control of the pressure to the tools. Similar local pressure control can be provided for other devices (see Detail 9).

A third option does exist but is rarely the preferred implementation. This is illustrated in Detail 10, and simply involves the piping of the Instrument Air to uniform outlets operated at the standard 185 psig, and then regulating each device with it’s own portable regulator fitted to the device or the permanent outlet.

It is also possible to blend the elements of the systems shown in these three figures to create a hybrid system appropriate to the facility’s needs.If a multiple pressure system is contemplated, be sure to size each of the branches at the appropriate pressure. Only for the purpose of sizing the source should they be considered as one system.

In the layout process, outlets are placed first. In O.R. settings where tool drive is required, a pressure control box is placed on a convenient wall, and includes one outlet. A second and occasionally a third outlet are placed in the closest possible proximity to the O.R. table. These

are often found on the ceiling columns or booms. These outlets may be “slaved” from the wall mounted control or they may employ a scaled down version of the control itself in the ceiling column or boom. Mounting the controller on the column or boom is generally superior when flow is considered, but less desirable from the viewpoint of staff access and ease of use.

After outlets are placed, the actual piping can be run and pipe sizing determined. This aspect of design is covered in detail in Chapter 9 of the BeaconMedæs Design Guide for Medical Gases.

Change of Use

The economic benefits of Instrument Air can be surprising, and of course it is the facility which is already struggling with the costs of a nitrogen system who is likely to see them most clearly. NFPA does provide for a system to be converted from one gas to another in a process termed “Change of Use”.

Change of Use requires that a system originally intended for one gas and therefore made non-interchangeable for that gas be converted so that it is equally non-interchangeable for the new gas. This means changing the source, changing the outlets, changing the demand checks on alarm components, relabelling and retesting as if the system was new. A conversion from nitrogen to Instrument Air is very feasible under these rules. Since the pipeline itself need not be disturbed, the cost of such a conversion is not excessive.

Sizing and Selecting an Instrument Air Source

Any Instrument Air source will consist of a primary source (usually a compressor) and a reserve source (a second compressor or a manifold header). Each element is sized separately and by it’s own rules.

To size the primary compressor, there are two considerations: first, the compressor must be large enough to drive all the tools, and second we don’t want to make the compressor any larger than is absolutely necessary. This is particularly true since there is a very large diversity in Instrument Air usage and in fact the average Instrument Air compressor will not run very much. To express this another way, when the Instrument Air is needed, there must be enough of it, but it is only typically needed in short bursts, so the system may sit idle for long periods.

The picture can be further complicated if the Instrument Air is being used for purposes in addition to driving surgical tools. Naturally, some of the other applications may place more steady demand on the system and change the diversity required.

The first consideration in sizing is to ensure that the tools which are likely to be in simultaneous use are covered. These tools can be very demanding, with typical usages ranging from 225-425 lpm (8-15 scfm). At least this quantity of air must be available, so this is the minimum size for a system.

More than one location will involve some degree of simultaneous use, and the calculation we recommend is that used by the HTM 2022 standard from the U.K., which allows for one tool at 100% and all remaining tools at 25%. The formula used is :350 + ((n-1) x 87.5)Where n is the number of locations using the system.

Where 350 lpm is taken as the base load for a tool, and “n” is the number of locations piped with Instrument Air or the number of tools.

If other applications are intended to use Instrument Air, they must be added to the tool demand based on a knowledge of the actual demand from that application. Some examples might include: operating pneumatic brakes for booms, which use negligible amounts of air and can be ignored as a capacity requirement; operating tools in the morgue, which might be treated like another tool-using location; operating a pneumatic O.R. table, which would have to be assessed based on a knowledge of the table itself; general lab uses, which might easily be greater than the use of air for tools when totalled.

The sizing of the reserve is identical if a duplex compressor is used as the source configuration. If the source configuration is a compressor with a cylinder header as reserve (a hybrid configuration), then the secondary must contain one hour’s supply. This is most easily assessed by taking the total demand calculated for the primary source and multiplying it by 60 (minutes to hours), then dividing by 6,200 l (220 scfm) to determine the number of cylinders required in the secondary (Detail 12 allows you to determine this with minimal calculations).

In the rare event that a manifold source will be used, this will be sized using a simple calculation of one cylinder for each ordinary O.R., and two for each O.R. intended for orthopedic or neurological surgery. Both sides of the manifold will be identically sized. If other applications are also going to be served form the manifold, they must be assessed individually.

The selection of the Instrument Air source may be made from Detail 13, which also will link you to the necessary information for system dimensions.

compared to Nitrogen, is a superior choice for any facility which needs high pressure gas for any reason. In the long run, the benefits are so compelling that we can anticipate nitrogen systems disappearing from the scene, entirely replaced by Instrument Air. However, that is some time in the future, and any facility built since at least the 1970’s probably has a nitrogen system already in place. Although the economics of Instrument Air are compelling, they are far more complex when a legacy system must also be considered.

Instrument Air systems are more costly initially, but the gas is far less expensive per liter. This means that there is a payback for virtually any Instrument Air installation, whether new or a change of use. The question is the time

frame for that payback. Naturally, the general rule will be the more gas used, the faster the payback. Small facilities using very little gas may find the payback too far in the future to justify the initial outlay, large facilities with heavy usage may find the savings grand enough to justify even a complicated change of use program. The only way to know is to do the math.

We highly recommend that every medical gas design engineer add Instrument Air to their repertoire, and in future evaluate every facility as a potential candidate. They will find in most cases Instrument Air is a money saver for their client.

systems from going empty should also look closely at the possibilities of performing a change of use conversion. They are likely to find the economics more favorable than they expected.

That middle range of facilities whose nitrogen usage is a nuisance but not high enough to justify the costs of conversion will be the ones who will have to refuse change of use. Should they ever be fortunate enough to renovate their O.R. or build new, they will certainly find Instrument Air very attractive, but they may be best advised to leave

well enough alone in the interim.

There are other possibilities for reducing the cost and labor involved with nitrogen which may be a half-way solution for such facilities. These involve conversion from cylinder (gaseous) sources to container (liquid) sources. While nitrogen will always be more expensive than compressed air, the reduction in cost can be significant, and the reduction in labor can be greater yet. More details on these systems can be obtained in the BeaconMedaes Applications Guide to Cryogenic Liquid Manifolds available through your BeaconMedaes representative.

Series B Console and Modular Headwall Medical Gas Outlet DISS Key Style

SPECIFICATION

DISS Medical Gas OutletThe DISS Medical Gas outlets for consoles and modular walls shall be gas specific for the services indicated and accept only corresponding DISS nuts and nipples. The outlets shall be UL listed, CSA certified, and be fully compliant with the latest edition of NFPA 99. All outlets shall be 100% tested for flow, leaks and connector attachment. The outlets shall be cleaned for oxygen service prior to shipping. The outlets shall be made in the U.S.A. A die cast, light gray, epoxy powder coated or plastic trim plate (optional) can be provided to trim each outlet assembly.

Outlet DesignA complete medical gas outlet shall consist of a gas-specific rough-in assembly and a matching gas-specific latch-valve assembly.

Rough-in AssemblyThe rough-in assembly shall be of modular design and include a gas-specific 16-gauge steel mounting plate designed to permit on-site installation. A machined brass outlet block shall be permanently attached to the mounting bracket to permit the 1/2" OD (3/8" nominal), type-K copper inlet tube to swivel 360° for attachment to the piping system.

Gas service identification shall be affixed to the inlet tube and the face of the mounting plate. A secondary valve shall be installed in the outlet block of the rough-in assembly for both pressure testing and preventing gas flow (except vacuum and WAGD) when the latch-valve assembly is removed for service. The rough-in assembly shall contain a double seal to prevent gas leakage between the rough-in and latch-valve assemblies after the wall is finished. A single o-ring seal shall not be acceptable.

Latch Valve AssemblyThe latch-valve assembly shall include an o-ring seal primary valve and shall be indexed to the corresponding gas service rough-in assembly to avoid accidental cross-connection. Latch valves shall telescope up to 3/4" to allow for variation in wall thickness. A metal cover plate insert with permanent color-coded gas service identification shall be included as part of the latch valve assembly.

Hose Assemblies, Valves, Fittings, and Components

SPECIFICATIONS AND ORDERING INFORMATION

Fittings and ComponentsAll BeaconMedaes DISS valves, bodies, nuts and nipples are manufactured to comply with the latest edition of CGA V-5, Diameter Index Safety System (Non-interchangeable low pressure connections for medical gas applications)

Gas Specific DISS Valve or DISS BodyDISS BODY: When the DISS nut and nipple are disconnected gas will continue to flow. DISS VALVE: Contains a valve mechanism and begins to flow gas when the DISS nut and nipple are connected and stops flow when the DISS nut and nipple are disconnected.

DISS valves and valve bodies are available with 1/4 -18 NPT male threads, 1/8 -27 NPT male threads or barbed ends for installation in hose assemblies

Gas Specific DISS NipplesThe gas specific DISS nipple mates with the gas specific DISS valve or valve body. They are supplied with O-rings where required and are available with 1/4 -18 NPT male threads,1/8 -27 NPT male threads or barbed ends for installation in hose assemblies

DISS NutThe DISS nut is used to secure the DISS nipple to the valve or valve body. Often times the DISS nut may be used on several different gases. The valve or body and the nipple are the components to make the system gas specific.

For assistance in determining the components you may require, please call 1-888-4MEDGAS to speak with one of our specialists.

HOSE ASSEMBLIES To order hose assemblies:

1. Select the fitting for each end of the hose assembly-one from (A) and one from (C) using the matrix shown. 2. Choose the appropriate part number according to the gas service required (B). 3. Replace the XX with a two-digit number from the chart (D). This two-digit number corresponds with the length of the hose required.

Example: A hose assembly for oxygen that is five feet long and uses a Geometric valve on one end and a Diameter-Index Safety System (DISS) nut and nipple on the other end would carry a part number of 6-139103-05

NOTE:Maximum length is thirty feet. Unless otherwise specified, all assemblies utilize 1/4” ID hose.
