Uniform Mechanical Code

The IAPMO Group has launched the 2021 revision cycle for the Uniform Mechanical Code; widely incorporated by reference into public safety law in many states.

BSR/IAPMO UMC 1-20xx, Uniform Mechanical Code (UMC). This code provides minimum standards to safeguard life or limb, health, property, and public welfare by regulating and controlling the design, construction, installation, quality of materials, location, operation and maintenance, or use of heating, ventilating, cooling, refrigeration systems, incinerators and other miscellaneous heat-producing appliances. The provisions of this code apply to the erection, installation, alteration, repair, relocation, replacement, addition to, use, or maintenance of mechanical systems.

This document is developed so that its technical concepts correlate with the Uniform Plumbing Code (UPC).  The UPC provides standards and requirements to safeguard life or limb, health, property and public welfare by regulating and controlling the design, construction, installation, quality of materials, location, operation and maintenance or use of plumbing systems. The provisions of this code apply to the erection, installation, alteration, repair, relocation, addition to, use, or maintenance of plumbing systems.

Project Need: Designation of the UMC as an American National Standard has provided the built industry with uniform mechanical standards resulting in a reduction in training costs and product development costs, and in price reduction for consumers. This American National Standard provides consumers with safe mechanical systems while allowing latitude for innovation and new technologies. This project is intended to keep the code current.

Stakeholders: Manufacturers, users, installers and maintainers, labor research/standards/testing laboratories, enforcing authorities, consumers, and special experts. *

The Complete Monograph of proposed revisions for the 2021 Uniform Mechanical Code has been released and available for public review.

UMC 2018 Technical Committee Meeting Monograph

Comments are due January 3, 2019.   We encourage subject matter experts at the workpoint in the education facilities industry — i.e. tradespersons, foremen, supervisors that have a user-interest point of view (the stakeholder who is the final fiduciary)– to participate in the development of the next revision of the Uniform Mechanical Code.  As we explain in our ABOUT we find that standards developers routinely attempt to cultivate the user-interest.

More detailed information about how all stakeholders may participate is available this link: Public Comment Page.    You may communicate directly with IAPMO’s standards staff here: IAPMO (International Association of Plumbing & Mechanical Officials) 4755 E. Philadelphia Street Ontario, CA 91761 Office: (909) 472-4241 Gabriella Davis gaby.davis@iapmo.org

Incident Handling

Eastern Michigan University

The Association of Public-Safety Communications Officials International (APCO) has released for public review a draft of its standard APCO 1.113.1 Incident Handling Process.  From the project prospectus:

The standard will take the call-handling process from its root. Starting with the call-delivery mechanism of the equipment, which can affect the call handling initiation, it will continue to the actual triage of the call to its dissemination. The goal is to bring the call-handling process into full circle from the initiation of the call through the caller triage and finally into the dissemination of information. This will include the continued support of responders through the dissemination portion.

Comments are due September 3rd.  You will find more information about the document and APCO’s public commenting process at the link below:

Education & Healthcare Facilities Committee

The emergent #SmartCampus is fundamentally

an electrotechnical transformation. 

The IEEE Education & Healthcare Facilities Committee provides a platform for leading practice discovery among electrical engineers who are responsible for campus power distribution systems.   In many cases, with research university power systems with upwards of 100 megawatts of base load supplying campuses and academic medical centers, many campus power systems are larger than investor owned, municipal or cooperatively-owned electrical utilities.

IEEE Education & Healthcare Facilities Committee 

The committee, founded in 2013, features open discussion, experience exchange, and solution consideration among thought leaders globally, every other week, in both European and American time zones.  It collaborates closely with the IEEE Standards Association and the NFPA Electrical Division through IEEE SCC-18.   All teleconferences are upon to the public and can be accessed clicking here: IEEE E&H Committee Teleconference Login

The committee meets every other Tuesday — 15:00 Central European time and 3:00 PM Eastern time in the Americas.  It meets online today, August 14th.  Login information is linked below:

2021 IBC Healthcare Facilities

The International Code Council has received all comments on its proposed changes to Group A codes which includes healthcare facility safety and sustainability concepts for the 2021 International Building Code.   Breakout committees are now sorting through the public comments and preparing them for the Group A Public Comment Hearings, October 24-31, 2018 in Richmond Virginia.  See: Complete 2018 Group A Schedule.  We encourage students, faculty and facility management professionals in the Richmond Virginia area to attend the ICC 2018 Group A Code Hearings October 21 – 31 in Richmond Virginia.  (LEARN MORE)

We participate as an observer in the healthcare committee with an eye toward how new proposals with effect design, construction, operation and maintenance of education and university-affiliated healthcare facilities.   The record of our work and attention to concepts in play is reported routinely on this site and always on the agenda of our weekly open agenda teleconferences.  At the moment there is not much for public stakeholders to do until the Public Comment monograph is released to the public on August 31st.  We will be participating in the ICC breakout committee meetings until then.

On August 31st, 11:00 AM we will host a breakout teleconference of our own to sort through all the safety and sustainability issues in play as a result of the public comments.  Anyone is welcomed to join this teleconference with the login information in the link below:

Posted July 1, 2018

We follow the development of safety and sustainability concepts on the agenda of the International Code Council (ICC) Group A Committee Action Hearings that took place April 15 to 25, 2018 in Columbus, Ohio.   A batch of public input (strike-and-bold/redlines) regarding healthcare facilities for the 2021 edition of the International Building Code (IBC) is linked below:

Healthcare Proposals Group A I-2 12-8-2017 (2)

Generally speaking, the healthcare facilities affiliated with large research universities are built to the same standard as healthcare facilities everywhere else.  We only point out that there are two differences — unique to university-affiliated healthcare systems — that might be brought to bear upon the development of the next revision of the IBC:

  • University-affiliated healthcare enterprises tend to be the destination for patients that need specialized care.  The destination of last resort, so to say, because those enterprises have physicians engaged in leading-edge therapies, and therefore a different (typically, higher) risk profile than most healthcare enterprises.
  • Essential utility supplies — water, power, telecommunications, etc. — can be complicated by the character of the utilities of the host municipality serving the perimeter of the campus; essentially a city-within-a-city.

All other safety and sustainability concepts are the same, as an examination of the redlines linked above should reveal.

Because the Group A Hearings is such an large undertaking,  breakout committees administered by ICC staff have been preparing public input for presentation at the hearings.   Several months of work by the healthcare committee is linked below:

2021 ICC Group A Healthcare Committee Proposal Administration

The International Code Council released the 2018 Report of the Committee Action Hearings on the 2018 Editions of the Group A International Codes.  The 313 page monograph linked below contains the results of the balloting of all Group A codes:

Report: 2018 – 2019 Code Development Cycle Group A

Public comments are due July 16th.  These concepts will eventually be incorporated by reference into state building codes and thereby affect #TotalCostofOwnership.  We encourage architects, engineers, education facility managers, shop foremen and front line tradespersons to set up a (free) cdpAccess account at THIS LINK to begin commenting on the monograph.  Ahead of the July 16th deadline we have set aside a time slot — next Thursday, July 12th, 11:00 AM – 12:00 PM Eastern time — to explain our comments on all the proposed changes to the 2018 IBC for the 2021 edition.  Anyone is welcomed to join this teleconference with the login information below:

ICC Group A Markup Session

Of course, the ICC develops many other consensus documents — it is hard upon the 2019 Group B codes — so we keep the entire ICC suite on the standing agenda of our weekly Open Door teleconferences every Wednesday, 11 AM Eastern Time.   Click here to log in.

2020 NEC | Health Care Facilities

We find gaps and overlaps among the constellation of consensus standards that set the standard of care for safety in sustainability in healthcare facilities.   Several ANSI accredited standards developers claim parts of the healthcare facility space; each according to the point of view reflected in their business models: International Code Council, Institute of Electrical and Electronic Engineers*, National Fire Protection Association, American Society of Heating and Refrigeration Engineers are among those that are typically incorporated by reference into federal, state and local safety regulations.

Most of those standards developers run relatively well-balanced technical committees that make decisions and deliver a leading practice document that can be referenced into public safety and sustainability regulations every three to five years.   However it can be a challenge for different engineering and management disciplines to apply the documents when these documents — or parts of these documents — develop out of step with one another.  We simply have to know what is going on and when.

Our focus today is on the Article 517 of what will eventually become the 2020 edition of the National Electrical Code.   NFPA has now released the transcript of public input for the technical committee updating safety and sustainability concepts for electrical power systems in healthcare facilities:

NEC 2020 Pre-Ballot Report CMP-15 70_A2019_NEC_P15_FD_PRELIMFR

Comments are due August 30th.

You may submit your comments directly to NFPA at this link: List of NFPA Codes and Standards.  You may also join one of our online markup sessions to “get down into the weeds” about emergent safety and sustainability concepts that will appear in the 2020 National Electrical Code.   We typically run through the proposals and prepare comments and limit our interest to concepts that only affect university-affiliated healthcare systems.  Login information for the next teleconference on August 14th 11 AM Eastern time is linked below:

NEC Markup

We also collaborate with the IEEE Education & Healthcare Facilities Committee which meets online 4 times per month in the Americas and Europe and with the IEEE Standards Association.

Keep in mind that NFPA 99 Health Care Facilities Code develops one year out of step with Article 517 of the National Electrical Code.   NFPA 1 Fire Code and NFPA 101 Life Safety Code — two other codes with parts that apply to the healthcare industry — develop on different cycles and have been covered here in previous posts.  We have also identified and discussed ICC, IEEE and ASHRAE consensus documents that cover healthcare facility structural, architectural, electrotechnologies and environmental air systems.

*Except for the National Electrical Safety Code — which is written as a “code” to be referenced into public safety laws , all other IEEE products are developed as “guides” or “recommended practices” that can be referenced into the codes developed by NFPA, ICC and ASHRAE.

 

Standard for Healthcare Administration

The University of Texas Medical Branch (UTMB) is the United States Technical Advisory Group Administrator for the first global standard for health care administration; developed by International Organization for Standardization Technical Committee 304 (Click here: ISO/TC 304).     The creation of this standard was initiated by UTMB and, if this document is incorporated by reference into public law, or adopted by the private sector as a performance benchmark,  it will have significant effect upon health care enterprises in every industry in the US — not the least among them the healthcare delivery enterprises in the US education industry.   

The core committee met July 13th at  NSF International Headquarters in Ann Arbor, Michigan.   A summary of the activity at that meeting will be posted here soon.   In the intervening time, for information about participating contact Lee Webster (lswebste@utmb.edu).

Quoting S. Joe Bhatia, CEO of the American National Standards Institute in a May 16, 2015 press release:

“With more than $360 billion spent annually on health care administration in the U.S., reducing costs and streamlining administrative processes in health care is a critical national priority,” said S. Joe Bhatia, president and chief executive officer of ANSI, the U.S. member body to ISO. “The newly formed ISO TC 304 shows great promise in tackling inefficiencies in health care administration worldwide, and ANSI proudly supports UTMB’s leadership role as acting secretariat on behalf of the United States.”

It is rare for a US educational institution to assume leadership at this scale. As an Accredited Standards Developer the UTMB will oversee the creation of standards and technical reports that define effective, interoperable, and comparable healthcare administration practices and metrics among healthcare entities. These practices and metrics will be limited to staff and operational management of healthcare facilities.  Excerpts from the standardization project identify the rationale:  

Rationale 1: Establishing healthcare administrative standards will reduce the cost of providing healthcare through the widespread adoption of interoperable metrics and practices.

Rationale 2: Reducing the cost of healthcare will make these services more affordable and thereby provide an opportunity for greater access to society.

Rationale 3: Improving the administrative and managerial performance of healthcare entities results in better healthcare outcomes for patients.

Rationale 4: Although numerous standards exist for the laboratory protocols, clinical services and patient care functions of healthcare organizations, there are scant standards that address administrative functions or these standards are specific to a particular healthcare entity.

Rationale 5: Standardizing Healthcare administrative metrics will create apple-to-apple comparisons of organizations performance that will better educate consumers and drive process improvement activities

Rationale 6: Rural and underserved communities will have access to effective practices that offer a roadmap to improve their own quality of healthcare services they receive.

Rationale 7: Positive support have been received from other ASD and members of the healthcare technical community

Rationale 8: Standards will complement standards developing efforts of existing ANSI and ISO standards developing committees.

Rationale 9: The healthcare community and its stakeholders are highly receptive to standardization and certification and will adopt approaches from these sources readily. 

Those practices and metrics that directly affect patient care and medical research are outside the scope of this standards effort. Clinical performance and patient safety and satisfaction standards will not be pursued by this ASD body.  ISO 304 will also not address 1) the management or administration of organizations that practice dentistry, 2) the production and use of medical devices or instruments, and 3) the capture and analysis of clinical medical information or procedures.   More detailed information is available in the documents linked below:

NFPA 99 | Healthcare Facilities Code

The NFPA 99 Healthcare Facilities Code committee develops a distinct consensus document (i.e. “regulatory product”) that is distinct from National Electrical Code Article 517; though there are occasional overlap and gaps.  It is worthwhile reviewing the scope of each committee:

NFPA 99 Scope: This Committee shall have primary responsibility for documents that contain criteria for safeguarding patients and health care personnel in the delivery of health care services within health care facilities: a) from fire, explosion, electrical, and related hazards resulting either from the use of anesthetic agents, medical gas equipment, electrical apparatus, and high frequency electricity, or from internal or external incidents that disrupt normal patient care; b) from fire and explosion hazards; c) in connection with the use of hyperbaric and hypobaric facilities for medical purposes; d) through performance, maintenance and testing criteria for electrical systems, both normal and essential; and e) through performance, maintenance and testing, and installation criteria: (1) for vacuum systems for medical or surgical purposes, and (2) for medical gas systems; and f) through performance, maintenance and testing of plumbing, heating, cooling , and ventilating in health care facilities.

NFPA 70 Article 517 Scope:  The provisions of this article shall apply to electrical construction and installation criteria in healthcare facilities that provide services to human beings.  The requirements in Parts II and III not only apply to single-function buildings but are also intended to be individually applied to their respective forms of occupancy within a multi-function building (e.g. a doctor’s examining room located within a limited care facility would be required to meet the provisions of 517.10)   Informational Note: For information concerning performance, maintenance, and testing criteria, refer to the appropriate health care facilities documents.

In short, NFPA 70 Article 517 is intended to focus only on electrical safety issues though electrotechnology complexity and integration in healthcare settings (security, telecommunications, wireless medical devices, fire safety, environmental air control, etc.) usually results in conceptual overlap with other regulatory products such as NFPA 101 (Life Safety Code) and the International Building Code.

Public input has been received by NFPA 99 technical committee administration and will be posted for public comment no later than February 27, 2019.  Until then, we will be sitting in on the expert discussions hosted by the ICC, IEEE, ASTM, ASHRAE and others.  We will slice through them all and host a teleconference for facility managers for university-affiliated medical research and healthcare delivery enterprises on August 23rd, 11 AM.  Feel free to login with the information the link below:

Posted June 1, 2018

It is not too early to begin formulating concepts for the 2021 revision of NFPA 99 Health Care Facilities Code.   Some of the concepts we are advocating in Article 517 for the 2020 revision of National Electrical Code (now being debated among several NEC working groups) may be more effectively placed in NFPA 99; though the concepts belong in either document is an issue over which good minds will disagree.

Several workgroups are already convening ahead of the Public Input meetings in Hiltonhead, SC in January 2018; one of which is examining proposals from Standards Michigan and the American Society of Healthcare Engineering for “rightsizing” the healthcare facility building power supply chain.  Access to the work in progress of those working groups is available at this link: 2020 NEC Concepts Landing Page

Public Input Closing Date is June 27, 2018.   

We will continue collaboration with the IEEE Education & Healthcare Facilities Committee which meets again twice Tuesday, November 21st.   Anyone is welcomed to join those teleconferences with the login information provided on the meeting agenda.

The education industry provides one of the largest markets for biosafety cabinetry manufacturers — particularly large research universities, university-affiliated healthcare enterprises and K-12 science laboratories.   When new research square-footage is budgeted the effective cost of this equipment is often difficult to determine; not just in per-unit terms but the degree to which environmental air management systems are affected.
