meeting which included general meeting procedures and a review of the

Annual 2017 revision cycle.

6. NFPA 55 Coordination: Rob Early, Chair of the NFPA 55 Technical

Committee, presented a proposed plan to better coordinate the requirements

for bulk storage of medical gases between NFPA 99 and NFPA 55. The

presented plan calls for a long term effort between the two committees that

will last until the completion of the 2021 edition of NFPA 99. A task group

this coordination. Task group members from NFPA 99 include, Keith

Ferrari, Barry Brown, Mike Frankel, Dave Dagenais, Marc Dodson, Jim

Lucas, Gary Bean, Dave Mohile, and Jonathan Willard.

7. Development of First Draft: The committee reviewed all 185 public inputs

(PI) and resolved them by either providing a committee statement or by

creating a first revision (FR) based on the PI. Other First Revisions were

also created. See the First Draft and First Draft report for the official

committee actions.

8. New Business: Several of the task groups formed prior to the meeting and

some formed during the meeting were charged with continuing their work.

Those include:

Task Group 1 (Dew Point): This task group will continue address current

Dew Point requirements. If our current dew point requirements are adequate,

suggest annex language explaining why. Members: Jonathan Willard, John

Gregory, Marc Dodson, Keith Ferrari, Tony Lowe, Mark Allen, Steve

Barker.

Task Group 3 (Category 3): This task group will continue to review the

update/reorganization of Category 3 system requirements in the 2015

edition. Members: Neil Gagne, Daniel Shoemaker, Jonathan Willard, Don

McIlroy, Spiro Megremis.

Corrugated Stainless Steel Tubing: This task group will continue to

review the addition of corrugated stainless steel tubing into NFPA 99. This

group should review the first draft to ensure that the new language meets the

concerns and needs of the committee. Members: Mark Franklin, Dana

Colombo, Tony Lowe, Pat Kelly, Ed Lyczko, Dave Dagenais, Ted Lemoff.

Task Group 9 (Lab Gases): This task group will continue their efforts of

identifying the requirements for piped medical gases in health care

laboratories. Chairman Lathrop and Jon Hart are to reach out to the NFPA

45 Chair and Staff Liaison to see if requirements can reside in NFPA 45.

Members: John Gregory, Jim Lucas, Jonathan Willard, David Volz, Mike

Frankel.

9. Next Meeting: TBD in the June/July 2016 timeframe.

10. Meeting Adjourned: The meeting was adjourned at 3:10 pm on August 14,

2015.

An engineered assembly of components that operate A United States Food and Drug Administration (FDA) approved and registered deviceused to separate air into constituent gases, typically providing oxygen 93 USP 93% as a drug product.


Oxygen concentrators, when used to supply oxygen 93% for drug applications, are medical devices as defined in the Federal Food Drug and Cosmetic Act and must meet specific requirements. A medical device is “an” instrument, apparatus, implement, machine, contrivance, implant, in vito reagent, or similar or related article, including a component part or accessory which is intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or other animals.

Public Comment No. 71-NFPA 99-2016 [ New Section after 3.3.129 ]

Oxygen 93 USPOxygen complying with Oxygen 93 USP Monograph


A separate definition is needed as there are two different USP Monographs. Oxygen, USP has an assay specification of “not less than 99.0% Oxygen” where Oxygen 93%, USP has an assay specification of “93% ± 3% Oxygen. Although they are both contained in the USP they are not the same but are two distinctly different drugs with different “strengths” and must be separate.

3.3.129 Oxygen USP.

Oxygen complying with oxygen USP or oxygen 93 USP monograph .


First Revision 107 as currently written and noted in 99:3.3.129 will result in the gas being mislabeled as a drug and that there are two different monographs that are not interchangeable. Oxygen, USP has an assay specification of “not less than 99.0% Oxygen” where Oxygen 93%, USP has an assay specification of “93% ± 3% Oxygen. Although they are both contained in the USP they are not the same but are two distinctly different drugs with different “strengths” and must be separate.

5.1.3.3.1.11

If indoors, and containing gases other than medical air or oxygen, the central supply location shall be equipped with an oxygen monitor that shallindicate when the oxygen level in the room is below 19.5 percent. The monitor shall have the following:

The oxygen sensor mounted on or near the central supply systemA visual

a

visual and audible annunciator outside the main entrance to the room .


Instructions to place the oxygen monitor on the manifold will most likely result in nuisance alarms. Placement of the sensor should be such that the room ventilation does not allow false alarms.

The proposal is a good safety precaution; however, the storage locations for medical gas cylinders should not be considered a permit-required confined spaces (29 CFR 1910.146). Also, a concern is whether the oxygen monitor will continuously activate an alarm (nuisance alarms) if the oxygen monitor sensor(s) are placed too close to any oxygen (or other medical gases/medical support gases) containers that may off gas as part of the standard design and operation of the container (ex. liquid containers – dewars) and not allowing the air exchanges from the ventilation system to dilute the vented gas as the ventilation system was designed to do.

The NFPA Directory states that the NFPA standards content "...shall also base its recommendations on one or more of the following factors: fire experience, research data, engineering fundamentals, or other such information as may be available" There was no technical justification submitted for this change and there have been no known incidents where the absence of any monitor or alarm has led to any hazard. Without compelling evidence to support the change this should be removed from the draft.

(16) They shall be designed to meet the operational requirements of 5.1.3.2 with regard to room temperature.


First I wish to thank the committee and express appreciation for the proposed clarification to "indirect" allowing electric.

I have seen med gas certifiers require design changes after equipment is installed due to different interpretations of what indirect means. For this reason I request the committee remove the "indirect" requirement or further clarify the intent of "indirect" because I believe the use of the word will still be confusing to users. Since the standard chooses to use the word "indirect" in lieu of alternative language stating "heating shall be by hot water, steam or electric" it implies that there are other design elements associated with "indirect" heating other than "hot water, steam or electric". As an example some med gas certifiers have interpreted that a unit heater would need to be located entirely outside of the room to count as "indirect". In addition, since the annex states "examples of indirect heating include..." the standard further implies there are other acceptable methods of heat that are indirect other than those listed; for example, a user could interpret that an "indirect gas fired heater" is an indirect form of heat and is acceptable while a "direct gas fired heater" would not be acceptable. I'm not certain that the previous example's interpretation is the true intent of the committee when utilizing the word "indirect". My personal interpretation of this requirement and the intent of the "indirect" term is that the committee does not want a piece of heating equipment with an open flame to be located within the room, thus my suggestion to require that "fuel fired equipment shall not be located in the room" and remove the indirect requirement. If the intent of the standard is that there are other design elements associated with the use of the term "indirect" I request they be further clarified to assist the users of the standard in meeting the intent of the language.

I am also proposing language that addresses the proposed revision to the annex requirement limiting heating elements to 212 degrees F. I am unaware of how the committee arrived at this value but suggest that if a higher value is acceptable it be permitted. As explicitly stated in the annex the intent of the committee is to allow steam heating, however as I would interpret the standard a limit on the heater element to 212 degrees F would effectively remove steam as a viable heating source. 0 psi steam will be at 212 degrees and as a practical matter can not be used because not exceeding the maximum temperature cannot be assured from a design perspective. The suggested value of 266 degrees F. is based on the temperature of steam at 25 PSI, with the intent to allow 15 PSI steam with a safety relief valve setting of up to 25 PSI. Any higher value as deemed appropriate by the committee above 212 or 266 degrees F is appreciated.

Due to formatting errors while entering this comment the next requirement in the standard is shown as revised. I made no recommended changes to that requirement.

An outlet valve shall be provided to isolate all components of the oxygen concentrator from the pipeline with the following characteristics:

(1) The valve shall have both manual and automatic actuation with visual indication of open or closed,

(2) The valve shall close automatically whenever the oxygen concentrator unit is not producing oxygen of a concentration equal to that in5.1.3.5.11.1,

(3) Continuing operation of the oxygen concentrator supply unit through the vent mode shall be permitted with the isolating valve closed.

5.1.3.8.1.2

If WAGD is produced by the medical–surgical vacuum source, the following shall apply:

(1) The medical–surgical vacuum source shall comply with 5.1.3.7.

(2) The total concentration of oxidizers (oxygen and nitrous oxide) of oxygen shall be maintained below 23.6 percent, or the vacuum pumpshall comply with 5.1.3.8.2.1.

(3) The medical–surgical vacuum source shall be sized to accommodate the additional volume.


The most common oxidizers that are present in combined use vacuum pump systems include gases such as nitrous oxide (N2O) and carbon dioxide (CO2). According to Wikipedia, N2O will decompose exothermically into nitrogen and oxygen, at a temperature of approximately 1070 °F, while CO2 requires much higher temperatures. If a system is exposed to such an environment, there are likely plenty of other problems to worry about. Not to mention, the cost of monitoring oxidizers is much more expensive than simply monitoring the oxygen concentration. So is dedicating an entire vacuum pump system that is required to be made from inert materials specifically WAGD purposes. The ability for health care facilities to monitor their vacuum pumps oxygen concentration would permit a similar standard for safety as well as offer a much more economical means for providing the same service. This could also more easily apply to existing systems, making them much safer for combined use scenarios. Any feedback would be appreciated. Thank you for your time.

Public Comment No. 91-NFPA 99-2016 [ New Section after 5.1.10.1.4 ]

TITLE OF NEW CONTENT5.1.10.1.5 Medical tubing with a non-metallic jacket shall have a flame spread index of 25 or less, and smoke density rating of 50 or less asdetermined by the Test Method for Surface Burning Characteristics of Building Materials, ASTM E84.


This comment resubmits PI 270, which was rejected and recommends that it be applicable to all tubing coated with non-metallic materials. PI 270 included the following Substantiation:

“A new 5.1.10.1.5 is added to provide a minimum flame spread index and smoke developed index for the plastic jacket of medical tubing using ASTM E84, which is widely used for these measurements. The values are identical to those used for Corrugated Stainless Steel Tubing used for fuel gas service. These values are compliant with the flame and smoke indices for Class A interior finishes in NFPA 101, Life Safety Code®. Class A is the most stringent class of interior finish materials in the Life Safety Code®”

The text is revised to be applicable to any tubing coated with a non-metallic jacket. While the submitter of the comment is not aware of any such coated tubing in use now, it is reasonably that a manufacturer of copper tubing might offer such tubing with a colored coated that would be specific for each medical gas. The substantiation provided with PI 270 remains valid, and the committee is encouraged to establish this high level of fire safety for all tubing with a non-metallic jacket that might be used for medical gases.

File Name Description ApprovedParticulate_Testing_of_Corrugated_Medical_Tubing_and_Copper_Type_L_Tubing.pdf


This comment follows up on a similar proposal to allow Corrugated Stainless Steel Medical Tubing, a new product for medical gas systems. The proposal was accepted by the committee at the first draft meeting and subsequently failed the letter ballot. Most of the committee members who voted negatively on the letter ballot stated reasons for rejection included concerns that the proposed material would not have the antibacterial properties of copper, and the possibility of water and particles being trapped in the convolutions of the tubing and being retained during the proscribed cleaning. These are valid concerns, and the comment addresses these. Specifically:

1. The tubing material has been changed to copper alloy with 95% copper.

2. Testing was conducted at Omega Flex’s facilities to determine if CMT could be cleaned by purging, along with a similar run of Type L copper tubing. These tests showed that CMT could be cleaned using an air purge as required by NFPA 99, and that the level of cleanliness was equal to that of the copper tubing run tested. See the Test Report submitted with this comment.

Several committee members voted negatively because of concerns over using mechanical fittings as an option to brazing. This is confusing as the Code has allowed mechanical fittings for some time. Specifically, NFPA 99-2015, allows:• Axially swaged fittings to be used to join copper or stainless steel tubing without restriction in paragraph 5.1.10.7. • Threaded fittings in very limited locations in paragraph 5.1.10.8.• Special fittings, which include listed gas fittings that provide a permanent joint and sealing integrity of a brazed joint, and dielectric fittings which can be a union in paragraph 5.1.10.9.

Other technical reasons for rejection included a statement that mechanical joints should not be allowed in sealed walls, potential for noise or harmonic vibration, the longevity of the tubing as compared to copper tubing which has been in use for the past 100 years.• NFPA 99 contains no restriction on where fittings can be located. It is noted that at least one manufacturer of axially swaged fittings states that their fittings can be used anywhere as needed, which includes in sealed wall spaces, stating in their on-line catalog that the fittings can be used to add branches to a medical gas piping systems “as fast as you can drain the lines” citing NFPA 99-2005 paragraph 5.1.10.7 (4).• Testing by Omega Flex has not shown any noise or harmonic vibration from flowing air through various lengths of CMT, up to 350 ft. • Similar tubing made of stainless steel has been in use piping fuel gas into buildings in the U. S. for over 30 years. While there have been problems, none have been aging related.

The proposed tubing is now called Corrugated Medical Gas Tubing (CMT), to differentiate it from the previously proposed Corrugated Stainless Steel Medical Tubing, and is made from bronze rather than stainless steel. By constructing the tubing from bronze there is sufficient copper (95%) to provide essentially identical antibacterial activity. ASTM B103, is specified for the strip form of the material from which the tubing is fabricated because there is no standard for the corrugated tubing shape. The alloy specified, copper alloy 51000, is 95% copper and 5% tin, with only traces of other elements such as lead, tin zinc, iron, and phosphorus. Other alloys are allowed in ASTM B103 that include lead, and lower amounts of copper that are not being recommended for CMT.• Fittings. The fittings that will be listed are swaged fittings requiring special, readily available tools to install. • Fittings Requirements. The fittings will be brass and will be axially swaged to provide gas tightness and pull-out resistance. The listing requirements for the fittings will incorporate the current requirements of NFPA 99 in 5.1.10.7.1 for axially swaged fittings. • Fewer Fittings. A significant advantage of CMT over the hard copper tubing currently required by NFPA 99 is that CMT is shipped in 250 ft rolls, considerably longer than the 20 ft. lengths of hard copper tubing normally available. Longer lengths of the corrugated tubing result in fewer joints, with correspondingly less potential contamination. Longer lengths of CMT are also available also on special order.• Seismic Resistance. CMT, being semi-flexible is inherently seismic resistant, the product will move and flex during a seismic event, unlike rigid tubing which is prone to rupture during such event. • Simpler Installation. Contractors will benefit from a simpler installation, and there is less possibility for contamination. Corrugated Medical Tubing (CSMT). The tubing has a bronze corrugated tube coated with a plastic sheath which is printed with the necessary information. The tubing and fittings must be listed. • Listing. Listing means that the product or system has been evaluated to a set of construction and performance requirements that demonstrate its suitability for the application and will be under continued factory inspection for as long as the listing is maintained.• UL Fact Finding Report. An example of a test program that was developed to show the durability of a new tubing system with respect to the mechanical, thermal, and sealing integrity required for this application was provided as part of a Fact Finding Investigation by UL. The issuance of the Fact Finding Report does not constitute an endorsement of any proposed amendment and in no way implies Listing, Classification or other recognition by UL and does not authorize the use of UL Listing or Classification Marks or any other reference to Underwriters Laboratories Inc. on, or in connection with, the product. While the tests described in this Fact Finding Report were performed on a stainless steel corrugated tubing product, it does show the type of tests that could be contained in a UL standard. Once the corrugated medical gas tubing with fittings is allowed in the code, UL can then develop a final


38 of 145 5/17/2016 3:43 PM

set of requirements for listing. The test requirements may be as outlined in the previous Fact Finding Report, or may be modified to ensure the requirements address all of the pertinent items of the revised code including the copper alloy tubing material.

While these comments address corrugated tubing product made from bronze, there have been numerous installations of stainless steel corrugated medical gas tubing in Europe over the last 8 years, which demonstrate proof of concept of a corrugated tubing system, and two additional installations are pending in Africa. These installations were purged and determined to be acceptable for service prior to use, and there have been no reports of contamination issues since installation. These systems are located at:

1. INTRODUCTION

The installation of medical tubing is governed by the requirements of NFPA 99, Health

Care Facilities Code, and Corrugated Medical Tubing (CMT) is being recommended to be

added to NFP A 99. The addition of CMT to NFP A 99 will allow another method of

installing medical gas tubing in health care facilities, which may allow lower cost, faster

installation, and fewer joints with correspondingly fewer opportunities for contamination

during construction and leakage.

The testing reported here was conducted to address reasonable concerns of NFP A 99

Medical Gas committee members who voted negatively during the First Revision process

of the 2018 edition of NFP A 99.

OmegaFlex has conducted comparative air flow tests on 25 foot lengths of Corrugated

Medical Tubing (CMT) and copper tubing Type L to show that CMT is equivalent to

copper tubing with respect to removing particulate matter, inadvertently deposited in the

tubing due to construction activities, by the purging procedure as found in NFPA 99,

Section 5.1.12.2.5.1 and that CMT can meet the cleanliness tests found in sections

5.1.12.3.6 and 5.1.12.3.7 under System Verification in NFPA 99.

Specifically, testing was done to determine if particulate matter could be detected leaving

the CMT system after purging. Identical testing was performed on%" copper type L tubing

establishing a baseline, since that is an approved material.

For the testing of particulate matter, two types of materials were used. The first is a fine

copper powder of uniform particle size (8 microns) was obtained. This size is in the range

of respirable particles, particles which during breathing can be expected to remain in the

lungs. Larger particles drop out due to their weight before entering the lungs, and smaller

particles will remain in the moving air as it is expelled from the lungs. This subject is well

known in the Industrial Hygiene field, where absorption of particles in the lungs are of

great concern. While there are differences in the concerns of industrial hygienists and

physicians, the selection of a sample contaminant in a uniform particle size provides a basis

for comparison that is in the range of sizes that are of concern to the lungs, and is believed

to be repeatable.

The second is particles of ground copper tubing. This simulates cutting and deburring

particles created during the normal installation of copper tubing.

The particulate tests were conducted on CMT and copper type L Tubing systems of 25 ft

lengths (no elbows or bends) to minimize the possibility of particles accumulating in the

tubing at bends and elbows. The CMT was 25 ft continuous length and the copper type L

consisted of coupled lengths of two 1 0 foot lengths and one 5 foot length.

2. SCOPE

All of the testing conducted was at Omegaflex in Exton, P A. It was conducted by

Omegaflex personnel and company equipment was utilized.

3. BACKGROUND

The testing conducted supports the theoretical knowledge that flow within a corrugated

pipe will create vortices and eddy currents within the corrugation valleys thereby lifting

particulates into the flow stream and subsequently removing them during the purge process.

This has been clearly documented in previously published data1 and a graphical

representation shown in Figure 1.

4. TEST PROCEDURE

All straight test samples were configured in a similar manner, the CMT was a continuous

length and the copper tubing was coupled with two 10 foot lengths and one 5 foot length.

End one ("supply end") had a connection for shop air supply with a flow meter; the other

end had a 1 micron filter paper assembly.

The testing consisted of samples and particulate matter as shown in Table 1.

Examination of CMT and Copper after testing.

Following the particle testing the tubing was cut at the prescribed length from the supply

end using a standard tubing cutter. This method was utilized since it did not create any

particles due to cutting. Observations were made by looking into the end of the tube and

verifying the presence of visible particulate matter. The findings are summarized in Table

3.

6. CONCLUSION

The CMT system performed similarly as the copper system under the same test conditions.

During the post testing inspection of the ID, a light film of the residual copper powder was

found on near the application point on both the Copper tubing and the CMT. It did not

completely cover the ID circumference, it was spotty. Further analysis found no

discemable difference between top and bottom of corrugations on the CMT.

From these tests it can be concluded that a fine, respirable type particles or ground copper

tubing particles introduced into a CMT system will be removed during standard purge

process as does with copper tubing.

5.1.10.2.1 Tubes for Vacuum.

Piping for vacuum systems shall be constructed of any of the following:

(1) Hard-drawn seamless copper tube in accordance with the following:

(2) ASTM B 88, Standard Specification for Seamless Copper Water Tube , copper tube (Type K, Type L, or Type M)

(3) ASTM B 280, Standard Specification for Seamless Copper Tubing for Air Conditioning and Refrigeration Field Service , copper ACRtube

(4) ASTM B 819, Standard Specification for Seamless Copper Tube for Medical Gas Systems , copper medical gas tubing (Type K orType L)

(5) Stainless steel tube in accordance with the following:

(6) ASTM A 269 TP304L or 316L, Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for GeneralService

(7) ASTM A 312 TP304L or 316L, Standard Specification for Seamless and Welded Austenitic Stainless Steel Pipes

(8) A312 TP 304L/316L, Sch. 5S pipe, and A403 WP304L/316L, Sch. 5S fittings

(9) Corrugated Medical Tubing meeting the requirements of 5.1.10.1.4 (2).


CMT is proposed as an acceptable material for field-installed medical-surgical vacuum and WAGD systems in addition to positive pressure medical gas systems. While CMT has a thinner wall than the copper tubing currently used for medical vacuum systems, the corrugations provide equivalent strength for the use.

5.1.10.2.2.1

If copper or CMT vacuum tubing is installed along with any medical gas tubing, the vacuum tubing shall, prior to installation, be prominentlylabeled or otherwise identified to preclude using materials or installation procedures in the medical gas system that are not suitable for oxygenservice.


This revision will provide the same installation requirements for corrugated metal tubing, which is made from bronze, as for copper tubing.

5.1.11.1.1

Piping shall be labeled by stenciling, printing, or adhesive markers that identify the patient medical gas, the support gas, or the vacuum systemand include the following:

(1) Name of the gas or vacuum system or the chemical symbol per Table 5.1.11

(2) Gas or vacuum system color code per Table 5.1.11

(3) Where positive pressure gas piping systems operate at pressures other than the standard gauge pressure in Table 5.1.11, the operatingpressure in addition to the name of the gas


An identical change was submitted as a proposal to allow printing the required information on the medical gas in the piping system. The committee rejected the proposal stating, “This section is meant to be a field-applied labeling rather than anything that comes from the manufacturer”. While this meaning may be clear to the committee, a reading of the requirement does not make it clear to others that printing by the tube manufacturer does not comply with the requirement.

All NFPA codes and standards are encouraged to be written in with performance based requirements. This comment supports that goal. The requirement ensures that all tubing is labeled. It is not important if the information is added in the field, or provided with the tubing, just that it is there.

NOTE: This Public Comment appeared as CC Note No. ___ in the First Draft Report on First Revision No. ___, and is also related to Public Input No. ____, Committee Input No.

The technical committee is directed to FCR-4 to see the new Chapter 15 for dental gas and vacuum systems. This was added by the CC to facilitate public review and is based on the work of a task group of PIP. The following items need to be addressed by PIP at the second draft stage:

- Ensure terminology is consistent with other chapters of NFPA 99 where appropriate. (i.e. remove the term “facilities” from risk application)

- Review and revise Chapter 5 as needed based on the new Chapter. (i.e. remove references to dental in 5.3)

- The risk approach of the Chapter should refer to “Categories” as shown in the FCR.

A.5.1.5

Station outlets/inlets should be located at an appropriate height above the floor to prevent physical damage to equipment attached to the outlet.The minimum number of station outlets/inlets for each system that is installed should be provided per the FGI Guidelines for Design andConstruction of Hospitals and Outpatient Facilities or other federal, state, or local codes. One method to use is s tation outlets and inlets listed and labeled in accordance with UL 1331, Station Inlets and Outlets, which are suitable fordistribution of nonflammable medical gas in rigid piping systems operating at standard operating pressures.


NFPA 99 does not prevent a listed station outlet/inlet from being used. However, if a listed station outlet/inlet is used, the station outlet/inlet should be listed as suitable for installation in accordance with the installation standard requirements. The purpose of Annex A is to provide explanatory material for informational purpose only. This proposal assists the user of NFPA 99 to identify those listed station outlet/inlets that are considered as suitable for installation in accordance with NFPA 99.
