1 There are many changes to NFPA 99 from 1993 to 2015, but we want to concentrate on the changes made from 2012 to 2015, and we need to know a little about how all of this developed into the 2015 edition.

2 We have gone thru changes in the names of systems, such as a Type I and Type II in 1993 to Levels 1, 2, 3, 4, and now to Category 1, 2, 3.. There is no longer a Category 4 for Labs since NFPA requirements in 99 are for Patient care only, not for labs. They placed the requirements for a Category 1 system into 5.1 and for a Category 2 system into 5.2 and Dental under 5.3

3 These Categories will cover the requirements for medical gases and vacuum systems, but you will have to go to Chapter 8 for the plumbing requirements and Chapter 9 for HVAC requirements. We cannot teach a med gas installer, based only upon the requirements of Chapter 5, as we did in the past. Now we will need to cover all the requirements found in Chapters 1, 3, 4, 5, 8, 9, and chapter 13 on gas equipment.

4 One of the most important changes made, was not in the Chapter 5 on gas installation, but was in Chapter 4, called fundamentals. In the 2012 Edition this Chapter consisted of explaining categories and introduced to us risk assessment. Risk assessment is a documented procedure by the hospital to determine the category that a room or area would need to meet. I know that I do not have to explain Risk Assessment to anyone here, but to us this was a major step in relieving the guessing on our part as to what may be going on in a certain area of the Facility.

5 The idea is that the facility, thru a documented procedure of risk to the patients, would define the category of an area. Because this process must be documented, the conclusions they come up with, will be put on this facility management shoulders, and they cannot blame the Engineer or Contractor, because they have stated that they have conducted a risk assessment, and have documentation that they have concluded that this category assignment, is safe for these patients.

6 One other thing that needs to be said is that now under (patient care spaces) that the governing body of the facility, or its designee shall establish patient spaces with the type of care anticipated, and it shall be their responsibility under to designate anesthetizing locations. This would let us know also what level of anesthesia will be administered, and whether or not we have to install a zone valve, which is not required in a minimal sedation area. This is going to get interesting in a few plastic surgeons and oral surgeons offices where they are notorious for being not exactly forthcoming with what will take place in some areas.

7 Classification of rooms in 2012 edition, have been changed to spaces in the 2015 edition. The designation of rooms implies that doors and walls are present and that may not be the case, so space is a more realistic term.

8 The definition of a space is a portion of the health care facility designated by the governing body that serves a specific purpose. When a facility accepts the fact that the space is a category 1, the risk assessment required to qualify for the other categories are not required.

9 In 2012 edition the maximum temperature of the room for cylinder storage was 130 degrees, this was changed in the 2015 edition to 125 degrees maximum and -20 on the minim so all cylinder temperatures would be the same Walls, floors, and ceilings in an indoor location of cylinders shall have a fire resistance rating of 1 hour, but doors, and other openings must have ¾ hour fire protection ratings. This change was made to bring this requirement in alignment with NFPA 101.

10 In 2012 under design and construction for central supply systems it called for 2 entry/exits. In 2015 NFPA added another paragraph that states if outdoors, bulk cryogenic liquid systems shall be provided with a minimum of 2 entry/exits. This was clarified for bulk systems to be included not just cylinders.

11 In an outdoor enclosure where either a bulk or cylinders were enclosed in a brick or block wall, ventilation is required. A new code requirement was added in 2015 that states that the fire barrier wall that is shared with another space will not have openings in the wall except for pipes and conduits that are protected by a fire stopping system in accordance with the building code. If it is not shared by an adjoining space the ventilation openings can be installed.

12 Also, new in the 2015 code is a provision for an auxiliary source connection for all source gases. This connection will be the same size as the main line and will be located immediately on the patient side of the source valve. It will consist of a tee, a valve, and a removable plug or cap, and the valve will be normally closed and secured. While the EOSE (emergency oxygen supply connection) is an emergency connection the auxiliary source connection can be used in a more planned process.

13 There is a new requirement for micro or mini bulk systems. If they are inside, they are stationary and will be filled in place. They are under the NFPA requirement of 20,000³ so they could be located inside, which requires that the bulk tank must be small enough to allow for a cylinder reserve as well, but the total gas volume has to remain under the 20,000³. If these systems are located outdoors they have to meet the requirements of NFPA 55

14 In the 2012 edition there was an omission of vacuum exhaust piping and joining requirements, but in 2015 it states that vacuum exhaust piping should be made of the same material as the vacuum piping. Same piping and the same joining requirements. The specification for stainless steel tube and fittings were added. This includes ASTM A269, A312 and A L and 316L

15 The valve requirements have also changed in You can no longer use a butterfly valve on vacuum and the full port valve description is eliminated. This has been replaced with; they shall have a maximum pressure drop of 0.2 psig in a pressure service and a 0.15 pressure drop in vacuum service. All other requirements are still in place ¼ turn construction, made of materials suitable for that service, shall have copper tube extensions, shall have a handle indicator if the valve is open or closed, shall be cleaned for oxygen service. They shall permit that they can be serviced in the pipe line. (3 piece)

16 In the master alarm requirements it has always been that any device would be wired independently to each master alarm. In 2015 it has changed the term wiring to communication. With the Ethernet, fiber optic, and wireless technologies of today changing wiring to communication allows for opportunities in the future. If may become more reliable since wireless would not be cut, or pulled lose by falling debris.

17 In the 2012 edition it was perhaps misleading that two medical air systems could not be interconnected, which was never the intent. The 2015 code clarifies that the same gases can be interconnected, which allows an extra back up in case of a problem.

18 The test pressure shall be maintained until each joint has been examined for leakage by means of a leak detectant that is safe for use with oxygen and does not contain ammonia. No ammonia is allowed as part of the mixture for testing.

19 In Section 3 they added the term qualified person who by possession of a recognized degree, certificate, skill or professional training and who by knowledge, training and experience has demonstrated the ability to perform the work.

20 Maintenance Personnel for Medical Gas and Vacuum systems Appropriate qualifications of Persons Performing Maintenance on Medical Gas Systems will be by any of the following A Documented training program on specific equipment, by the facility that the person is employed by, or contracted with.
