Nitrous Oxide Vapor Pressure Curve from CGA Handbook of Compressed Gases, 5th edition.


No empirical data was given to change the min. temp from -20F to +20F. CGA G-8.1 (2007) Standard for Nitrous Oxide Systems at Consumer Sites: "8.2 Requirements: These storage vessels shall be designed, constructed, and tested in accordance with the appropriate requirements of the ASME Boiler & Pressure Vessel Code, Section VIII, Division 1, Unfired Pressure Vessels [14]. Special construction is required for operating temperatures below –20 °F (–29 °C). In Canada, the design and installation of these vessels must be approved by the Pressure Vessels Department of the appropriate provincial government."

The Code of Federal Regulations (29 CFR 1910.101), states, "the in-plant handling, storage, and utilization of all compressed gases in cylinders, portable tanks, rail tank cars or motor vehicle cargo tanks shall be in accordance with Compressed Gas Association Pamphlet P-1."

A temperature of - 20° F will provide an adequate cylinder pressure for a medical supply system (188.3 psig and 200.3 psig for nitrous oxide and carbon dioxide, respectively). Leaving the current plus + 20 F would prohibit outside systems on most of the USA (without additional heating devices or additional structures with additional unnecessary costs).

In 2002: the explanation given was: The minimum temperature for nitrous oxide and carbon dioxide results from the fact that these gases are actually above their triple point in a standard cylinder and are thus in liquid form inside the cylinder. Their pressure-temperature curves are steep, so they lose pressure rapidly as temperature falls, reaching a point where the liquid simply cannot vaporize, and the gas cannot draw off. A temperature of - 20° F will provide an adequate cylinder pressure for a medical supply system (188.3 psig and 200.3 psig for nitrous oxide and carbon dioxide, respectively). Leaving the current plus 10 (or plus 20) would prohibit outside systems on most of the USA (without additional construction utilizing heating devices or additional structures that will add unnecessary costs).

The high pressure cylinders, either steel or aluminum, are manufactured and tested for temperatures at or below - 20 degrees Fahrenheit.There are control modules/manifolds (AMKO, ACME, Chart) installed, at hospitals, in areas of the USA where temperatures reach - 20 degrees Fahrenheit or below. These modules operate and meet the delivery line pressure requirements of NFPA 99. CGA G 8.1 (2007) Standard for Nitrous Oxide Systems at Customer Sites. Scope: This standard covers the general principles recommended for the installation of Nitrous Oxide systems on medical or industrial customer premises. Such systems consist of a central supply, which can be either cylinders connected to a common manifold, liquid containers, or bulk liquid, and the associated equipment and piping required for connecting the central supply to the line supplying the nitrous oxide to the point of use.

Section 8.2 RequirementsStorage vessels shall be designed, constructed, and tested in accordance with the appropriate requirements of the ASME Boiler & Pressure Vessel Code, Section VIII, Division 1, and Unfired Pressure Vessels. Special construction is required for operating temperatures below - 20 degrees Fahrenheit (- 29 degrees Celsius).

5.1.3.3.3 Ventilation. ( Please see 9.3.6 Medical gas storage and transfilling for room ventilationrequirements.)5.1.3.3.3.1 Venting of Relief Valves.

Indoor supply systems shall have all relief valves vented per 5.1.3.5.6.1 (4) through (9).5.1.3.3.3.2 Ventilation for Motor-Driven Equipment.

The following source locations shall be adequately ventilated to prevent accumulation of heat:

(1) Medical air sources (see 5.1.3.6 )

(2) Medical–surgical vacuum sources (see 5.1.3.7 )

(3) Waste anesthetic gas disposal (WAGD) sources (see 5.1.3.8.1 )

(4)

5.1.3.3.3.3 Ventilation for Outdoor Locations.(A)

Outdoor locations surrounded by impermeable walls, except fire barrier walls, shall haveprotected ventilation openings located at the base of each wall to allow free circulation of airwithin the enclosure.(B)

Walls that are shared with other enclosures or with buildings shall be permitted to not haveopenings.(C)

The fire barrier wall shall not have openings or penetrations, except conduit or piping shall bepermitted provided that the penetration is protected with a firestop system in accordance withthe building code.


I think one of the biggest concerns I had with 2012 was no reference to room ventilation requirements guiding the installer/designer to look to 9.3.7 (2012) for these requirements. I would like to see the complete ventilation section reinstated in chapter 5 under venting for ease of use to the installer and designer. If this is not possible a simple reference to 9.3.6 (2015) would be sufficient.

TITLE OF NEW CONTENT(7) Control circuits utilizing fuses for overcurrent protection shall be provided with means to replace the fusewithout interuption to the control circuit.


Currently some medical air compressor manufacturers are utilizing fuses to protect the compressor PLC. The compressor PLC also control the air treatment equipment, dryers, co & dp monitors, condensate drains, etc. If the fuse blows the PLC no longer received power and the aforesaid equipment will not operate.

NFPA 70 requires a control panels to have means to disconnect without flipping a main breaker - In the field there are numerous medical air compressor that comply with NFPA 99 but not NFPA 70. Electrical Inspectors do not find the problem due to the medical air compressor system have control panel mounted disconnects that appear at a glance to disconnect the complete panel but the panel is still HOT.

(C) Each compressor motor shall be provided with electrical components including, but not limited to,the following:

(1) Dedicated disconnect switch installed in the electrical circuit ahead of each motor starter

(2) Motor starting device

(3) Overload protection

(4) Where compressor systems having two or more compressors employ a control transformer orother voltage control power device, installation of at least two such devices.

(5) Control circuits arranged in such a manner that the shutdown of one compressor does notinterrupt the operation of another compressor

(6) Automatic restart function, such that the compressor(s) will restart after power interruptionwithout manual intervention

(7) Electrical devices not directing controlling the operation of the compressors shall be poweredfrom a separate EESS power feed.


We had a single feed coming in to a fuse block that fed the entire air treatment center. When a 2 amp control fuse blew, the entire air treatment center was shut down. This created a hazrard to the care of our patients and for the tech who came to serve the unit being that the panel was still live.

Sub-Sections] ]

New or replacement

valves shall be

as follows:

They shall be of the quarter turn, full ported, ball type.

They shall be of brass or bronze construction.

They shall have extensions for brazing.

They shall have a handle indicating open or closed.They shall consist of three pieces permitting in-line serviceability

permitted to be of any type meeting the following conditions:

(1) with a maximum pressure drop at intended maximum flow of 0.2 psig in pressure service and0.15 inHg in vacuum service*,

(1) quarter turn to on to off,

(2) constructed of materials suitable to the service,

(3) provided with copper tube extensions for brazing,

(4) clearly indicating to the operator if they are open or closed,

(5) permit in-line serviceability,

(6) cleaned for oxygen service by the manufacturer if used for any positive pressure service .


Substantiation

The Draft 1 proposal from Jim Lucas on this clause has substantial merit in four specific respects:1. there is not particular reason that a ball valve is necessarily better or worse than any other valve type in medical gas service.2. the standard already permits butterfly valves in vacuum (5.1.4.3.2), which is demonstrably a far worse restriction in absolute terms than many other valve types and has been permitted in a far more pressure-loss sensitive application (vacuum) with no known issues.3. the current standard already permits three way valves (5.1.3.6.3.10) which are also far more flow restrictive than standard balls valves. 3. the current wording is unnecessarily design restrictive.

It is therefore the intent of this submission to revise the wording of the standard to reflect the genuine concerns underlying this paragraph and thereby move to a performance rather than prescriptive clause.

In researching valve types, the standard for expressing valve "resistance to flow" is the Cv value which is readily available for all valves. However, standard medical gas design practice is to design based on pressure drop across the pipeline.

It is thus necessary to convert from Cv to pressure drop, and a formula exists to perform this calculation:

5.4X10-7 * SpGr * T * Q2 SpGr = Specific Gravity referenced to Air (1)�P = ––––––––––––––––––––– T = Temperature °Rankine

Cv2 * Pout Q = flow in SCFH Pout = Pressure absolute

It is standard design practice to allow a 5 psi pressure drop across a pressure gas pipeline and 4 or 5inHg across


14 of 97 5/10/2013 9:14 AM

a vacuum pipeline (ref: BeaconMedaes Medical Gas Design Guide, Chapter 4; ASPE Databook Vol. 3 page 68-69)

The standard requires a typical 5 valves between source and outlet (source, main, riser, service and zone). It seems reasonable to allot to these five a worst case 20% of the total loss, or 1 psi for pressure and 0.75 inHgV for vacuum.

Thus, in a workable design each of these 5 valves could be permitted 0.2 psi drop for pressure and 0.15 inHgV, and the proposal is based on these values.

This will require an engineer to utilize the formula (having obtained from the manufacturer the Cv value of the valve under consideration) to determine the loss expected from that valve under their specific design conditions. However, given that calculation, the designer would be free to use any valve which meets the other criteria in the clause. If the valve seemed to be overly restrictive, they would also be at liberty to use a larger (and higher Cv) valve, which is not an option implied in the present standard. **To see the impact of this, the following table will allow some comparisons:
