PIPE DREAMS – Thinking About Bulking Up?

Fred Evans, CEO
Medical Gas Management, LLC

As major oxygen suppliers/manufacturers are involved in mergers and acquisitions, oxygen supply systems are going through a much needed transformation. For years, the NFPA 50, Standard for Bulk Oxygen Systems went unchanged and was desperately in need of updating. Finally, in 1996, a new NFPA 50 Standard was published.

Oxygen suppliers own a majority of bulk liquid oxygen vessels, cylinder reserve and regulators. User facilities pay a lease based on the kind and size of their bulk equipment. Typically, the facility owns the pad, enclosure and source valve. The required annual inspection of bulk liquid oxygen systems is normally the responsibility of the oxygen supplier and upgrading is done at their discretion. Our inspections of these systems reveal that nearly 90% of the installations would not pass current criteria for design and installation.

All of this activity, together with several major tragedies, stirred a movement to improve the overall reliability and design of the very heart of the oxygen system, the bulk liquid oxygen delivery equipment. The FDA has taken a lead role in assuring suppliers develop strict policies and procedures when health care facilities are involved. Suppliers like BOC have invested in new mobile installation teams along with contracting third party testing agencies to insure compliance prior to connecting to the hospital.

Why change a liquid oxygen tank? This decision is usually based on one of the following:
1. There is a need to relocate bulk oxygen storage because of new construction
2. The liquid equipment is being updated
3. The facility is changing suppliers
4. The hospital requires larger capacities

Insuring your systems design meets the requirements of NFPA 99 and 50 is ultimately the responsibility of the facility. Keeping your oxygen system in service during a change out of your vessel and equipment is also not without risk. Proper planning is essential during a change or relocation of your bulk system. For a smooth transition, the following key points should be included in your plan:
• The temporary system must have a backup system
• Insure that temporary regulators are duplexed
• Be sure you have calculated your temporary volume correctly
• Insure that you have the required low pressure inlet connection and that it is connected to your oxygen main line
• Provide and test for required signals
• Inspect the supplier’s work, tubing, hangers and regulators

Remember, during any emergency you may have to operate the bulk equipment.

FACILITIES FORUM

The following are some recent questions addressed to the Facilities Forum. Send us your questions or comments by mail or E-mail at medgas@ionet.net.

Q: How does "grandfathering" appear in the NFPA 99, 1999?

A: In general, NFPA updates apply to new construction and new equipment. When a medical gas system is remodeled or upgraded, that portion of the system must meet current NFPA requirements. And, if the performance of an existing system is adversely affected by the remodel or upgrade, that portion of the existing system must also be renovated to comply with the current standard. For more specific information, consult NFPA 99, 1999 or contact us at MGM to research your specific situation.

Q: Am I required to have two master alarms?

A: To determine whether a piping system in a facility needs two master alarm panels, you must know if the system is classified as an NFPA Level 1, Level 2, Level 3 or Level 4. A Level 1 system is required to have two master alarms in parallel. In future issues of Medical Gas Matters! we will review the differences in each of these classifications.

Q: What can I do about a manifold that doesn’t have dual line regulators?

A: This question goes back to the "grandfathering" issue. If the manifold is adversely impacted by a remodeling project, or if the equipment has failed, you must replace it with a dual line manifold. At this time, if neither of these conditions exists, you are not required to upgrade the equipment.

Meet Dr. Ervin Moss, Medical Director for MGM

Jan Szijarto

Ervin Moss, M.D., a well-known and highly respected anesthesiologist has devoted his professional life to quality care and patient safety in medical gas systems. This commitment led to his introduction to Fred Evans and his appointment to the position of Medical Director for Medical Gas Management, LLC The two men have collaborated on projects designed to educate the medical community to importance of safety in medical gas systems. Recently, I had an opportunity to review with Dr. Moss his distinguished career, and his passion for quality care in anesthesiology. Excerpts from that conversation follow:

MGM: Dr. Moss, how did you choose the field of anesthesia as your life’s work?

EM: In the mid-50s, anesthesiologists administered only 16 percent of anesthetics. I recognized an opportunity to participate in a new and much needed specialty. More important was the negative reaction I had to other divisions of medicine during my clerkship in Chicago. At that time, hospitals had huge wards filled with very sick patients who were cared for under rather primitive conditions. The only truly organized department I saw was during my clerkship at Chicago’s Sinai Hospital. Thus, my exposure to a well-managed, up-to-date anesthesia department resulted in my choice of specialty.

MGM: Was there a particular incident that motivated you to take an active role in promoting safety and understanding of medical gas systems?

EM: Before becoming actively involved in medical gas systems safety, I was very involved in patient safety. In 1975 there was a malpractice crisis in New Jersey. It was then that I conceived the idea that in a near-perfect world of well-equipped and trained anesthesiologists using the latest anesthesia machines and monitors, the exposure to malpractice could be limited or prevented through high quality care. The concept was a form of preventive medicine in the anesthesia specialty.

While in Florida, on an inspection assignment for an insurance company, I was introduced to particulate contamination of medical gas pipelines. This was a problem I knew nothing about. Pete Winborne, an associate of Medical Gas Management, had identified the contamination and it was he who introduced me to Fred Evans and MGM. Recognizing that medical gas systems represented another loophole in the anesthesia patient safety net, I flew to Bethany, Oklahoma to learn all I could about med gas systems from MGM. This was an area of anesthesia patient safety yet to be explored by the anesthesia community.

MGM: You have a history of involvement with the Anesthesia Patient Safety Foundation and are Chairman of the APSF Work Group on Medical Gas Vacuum Systems. What is the main focus of the Committee you chair?

EM: As a member of the Board of Directors of the Anesthesia Patient Safety Foundation (APSF) and as a member of the Committee on Technology, I have been able to create an awareness, within the APSF, of medical gas system problems. I invited Fred Evans to present an exhibit of "horrors" found by MGM in hospital medical gas vacuum systems to the APSF. The exhibit was shown in New York, San Francisco, San Diego, Atlanta, Atlantic City and Philadelphia.

Another success was the inclusion of a chapter on Patient Safety and Medical Gas Systems that I co-authored for the text, Patient Safety and Anesthetic Practices. I like to believe that these efforts resulted in the recent expansion by the JCAHO into medical gas system inspections.

MGM: How do you influence medical professionals to pay attention to their medical gas systems?

EM: Primarily by making them aware of medical gas systems. The lack of awareness starts in residency programs. No attention is given to the vital anesthesia system that is beyond the walls. I hope to see residency programs include lectures on medical gas systems, starting at the bulk site and ending at the patient anesthesia machine interface. An anesthesiologist should know the entire system. Interested anesthesiologists are aware of the anesthesia machine, but are ignorant of what is beyond the walls.

MGM: What problems do you encounter most often in medical gas systems?

EM: Lack of education, not only with anesthesiologists but also with many state and local inspectors who certify new or modified systems. They have little understanding of the NPFA codes that apply to medical gas systems. For example, I recently visited a new five room OR suite and, at first glance, noticed the master alarm panel was set up for only 4 rooms. There was no alarm for the fifth room. Yet, the state inspector approved the OR for use with one room missing from the master alarm panel.

MGM: What innovations would you like to see in medical gas systems over the next 5 years?

EM: I believe there are many things that need to be done. First, the anesthesia community must become educated to MGVS starting with residents, progressing to CME and refresher courses for the entire anesthesia profession. If this can be accomplished, other improvements will follow.

Educated anesthesiologists must be involved in the construction or modification of ORs. Currently, the end user, the anesthesiologist is often ignored in the planning phase of new construction and remodeling.

Certification should not be left in the hands of local fire or building inspectors. We need a nationally recognized organization much like the FAA is to aviation or FDA is to drugs, to oversee certification of medical gas systems. Anesthesia gases are medicines and should be treated as all other medications in the United States.

These goals can be achieved. My focus has always been on patient safety, not only in MGVS but also in hospital, office and surgery-center venues. As Executive Medical Director of the New Jersey State Society of Anesthesiologists, I am involved in politics, including the politics of patient safety. At this time, New Jersey is the only state with regulations for all three venues.

MGM: How do your spend your leisure time?

EM: My schedule keeps me quite busy, so I don’t have a lot of leisure time. I still administer anesthesia whenever I am able. I have given interviews on office based anesthesia and patient safety for USA Today, the New York Times, the Boston Globe and George. I appeared on a segment of Dateline, NBC that aired on April 11, 2000. Recently, I was appointed Clinical Professor at Robert Wood Johnson Medical School. Lecturing is another avenue I am pursuing to achieve my goal of educating the medical community and the public to the dangers of office based anesthesia including improperly designed and installed medical gas systems.

MGM: Thank you for your time and insights.

Read The Fine Print

Corky Bishop, P.E.

Recently, I did a rough-in inspection of an outpatient ambulatory surgery center. This facility has no patient rooms, meaning it will not have any overnight patients. The design firm correctly classified the facility as a Level 2 piping system. The design called for a single master alarm panel to be located at the nurses’ station, with the main area alarm panel located in another corridor.

Level 2 systems allow for just one master alarm. However, the fine print in the Standard requires gauges be present at the master alarm location to monitor the pressures in the mains. Typically, master alarm panels do not have gauges. Two options were available to correct the problem. The surgery main area alarm with its gauges could be relocated next to the master alarm panel at the nurses’ station. In this case, re-wiring and repair of walls at two locations would be required. Another option would be to install wall-mounted gauges near the master alarm panel. This choice presented fewer obstacles for the installer.

The specification for this job called for it to comply with the most recent edition of NFPA 99. The demand check fittings provided for the master alarm pressure switches were all alike. The NFPA 99, 1999 edition requires fittings to be gas specific to avoid connecting them to the wrong line during calibration or repair. DISS fittings are perfect for this application.

The contractor faxed a copy of the inspection report to the design firm. After reviewing NFPA 99, 1999, the design engineer agreed the corrections were necessary and produced the paperwork to implement them. This was accomplished three weeks before final testing was scheduled. It helps to get your certifier involved early so there are no surprises at the last minute.

If you think these kinds of problems don’t happen, give us a call. It’s our job to find them.

The Value of Good Design

Malcolm Pollard, Eastern Regional Manager

It’s the headline in the newspaper, the local news media has a field day reporting it, the community is abuzz with anticipation and the hospital administrator hasn’t smiled this much since his team took first place in the charity golf tournament. What could possibly create this much excitement in the community? After years of dreaming, planning and fund raising, the local medical center is finally going to break ground on the new wing! The architect’s rendering is breathtaking—this glorious building will be a real asset to the community. The Hospital Board proclaims this will be the finest facility in a 5 county area. But will it?

In the medical arena, an aesthetically pleasing building is a joy to behold, but the real value of the building is in what you can’t see. It’s the life support systems beyond the walls that are critical to the value of a facility. Many times design of these essential elements are entrusted to professionals who are unaware of, or lack an understanding of the standards that govern specification, installation and certification of the medical gas systems.

How do you ensure that a newly constructed or renovated medical gas system is safe for clinical use? The most cost effective way to achieve a code compliant, certifiable medical gas system is to include a medical gas specialist in the preconstruction planning, design review and inspection of the installation as the project progresses.

Problems I've encountered can be placed in one of three categories: design specifications, equipment specifications, and the installation process. For example, one hospital had 24 zone valve boxes designed and installed inside the room with outlets they control. Another hospital had an acute care zone that served 10 beds with 11 area alarm panels installed, one for each bed and one for the zone. The zone required only one alarm panel. A very common problem with area alarm panels is not knowing to which side of the zone valve box the pressure sensor should be connected.

This equipment specification problem occurred in a surgery clinic that had only 2 operating rooms with a single medical air outlet in each room. A $25,000 air compressor system was installed for these two outlets. A small medical air manifold
system would have been more than adequate, certainly less expensive, and code compliant.

In another facility, a section of medical gas pipe (oxygen, medical air, and vacuum) was all labeled as OXYGEN. A hospital with a newly completed emergency department ready to start treating patients, called MGM to certify their medical gas system. After listing two pages of discrepancies and finding nothing code compliant with regard to medical gases, it was obvious this facility had major problems. Of course, when even one problem occurs, a system cannot be certified until the correction is in place.

Including a medical gas specialist to review plans and specifications at the beginning of a project and provide inspections throughout construction will eliminate problems like these. Correct schematics of your system will facilitate maintenance, troubleshooting and changes that may be added at a later time.

There is a real dollar and cents savings in not purchasing inappropriate equipment, and not having to dismantle newly constructed walls to replace items. Less tangible savings come with the peace of mind in knowing that there won’t be delays in utilizing the facility due to certification problems and, more importantly, that all steps have been taken to insure patient safety.

MGM has the staff, experience, and expertise to provide you the best medical gas system. Calling us for technical assistance could be the best phone call you make when planning your new project.
