Fuel Cell Power Systems

 

Inventor of the fuel cell | CLICK ON IMAGE

We have been following the developmental trajectory of another “alternative energy” – related consensus product — NFPA 853  Standard for the Installation of Stationary Fuel Cell Power Systems a document that sets the criteria for minimizing fire hazards associated fuel cells power generating technology installations; many of which are pre-engineered and pre-packaged by manufacturers.

Keep in mind that it is an installation standard and “agnostic” about the type of fuel cell technology.  As such, it is likely referenced in energy project design guidelines and construction contract specifications.  From the document prospectus:

Scope:  This standard shall apply to the design, construction, and installation of stationary fuel cell power systems and shall include the following:

(1) A singular prepackaged, self-contained power system unit

(2) Any combination of prepackaged, self-contained power system units

(3) Power system units comprising two or more factory-matched modular components intended to be assembled in the field

(4) Engineered and field-constructed power systems that employ fuel cells.

The current edition of NFPA 853 is dated 2015

The NFPA Technical Committee on Electric Generating Plants has already begun work on the 2020 revision.  A selection of First and Second Draft documents are posted below:

NFPA 853_F2019_ECG_AAA_SDmeetingagenda_04_19

NFPA 853_F2019_ECG_AAA_FDmeetingagenda_04_18

Response to the Second Draft Report under NFPA’s NITMAM process are due August 29th. 

We normally collaborate with the IEEE Education & Healthcare Facilities Committee on consensus products of this nature because that is where the most informed locus of expertise lies.   That committee meets online four times monthly in European and American time zones.   We also host our own codes and standards for power and telecommunication systems teleconference every month.  See our CALENDAR for the next online meeting; open to everyone.

Tolkien, author of “The Lord of the Rings” and “The Hobbit,” completed his studies at the University of Birmingham in 1915. He graduated with first-class honors in English Language and Literature. After graduation, Tolkien went on to serve in World War I before embarking on his distinguished career as a writer and academic.

Hosting open-air celebrations such as graduations and cultural requires sensitivity to audio standards that ensure high-quality sound and audience safety.  Today at the usual hour we examine the standards covering sound system design, noise control, loudness levels, equipment specifications, weather and local environmental considerations.
Surprisingly, there are many even without approaching the not insignificant cabling system standards.  We pick three representatives titles which cross reference one another:

 

World Health Organization recommendations for limiting exposure to leisure noise (e.g., concerts) to a level exceeding 80 dBA for 24 hours or 140 dB peak sound pressure to prevent hearing loss.  Recommendations for speech heavy events will defer from musical events.

 

Audio Engineering Society Guideline AES56-2008 which provides recommendations for loudspeaker placement in sound reinforcement systems.  Key points include:

    • Height and Angle: Line array speakers are often elevated (e.g., on trusses or poles) and angled to cover the audience while reducing sound spill to non-audience areas.
    • Distance: Main speakers should be placed to avoid excessive sound pressure near the front (e.g., 95–100 dBA max for audience safety) and ensure clarity at the back.

Acoustical Society of America ASA-2010 Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools.  While primarily for schools, this standard’s principles can apply to open-air educational or community events, emphasizing background noise control and speech intelligibility.  For open-air audiences at events like outdoor lectures or festivals, speaker placement should minimize interference from environmental noise (e.g., traffic, wind). The standard suggests maintaining a signal-to-noise ratio where speech is at least 15 dB above background noise for clarity.

Fire Alarm & Signaling Code

“Prometheus Bound” | Thomas Cole (1847)

NFPA 72 National Fire Alarm and Signaling Code is one of the core National Fire Protection Association titles widely incorporated by reference into public safety legislation.   NFPA 72 competes with titles of “similar” scope — International Fire Code — developed by the International Code Council.  We place air quotes around the word similar because there are gaps and overlaps depending upon whether or not each is adopted partially or whole cloth by the tens of thousands of jurisdictions that need both.

Our contact with NFPA 72 dates back to the early 2000’s when the original University of Michigan advocacy enterprise began challenging the prescriptive requirements for inspection, testing and maintenance (IT&M) in Chapter 14.  There are hundreds of fire alarm shops, and thousands of licensed fire alarm technicians in the education facility industry and the managers of this cadre of experts needed leadership in supporting their lower #TotalCostofOwnership agenda with “code-writing and vote-getting”.   There was no education industry trade association that was even interested, much less effective, in this space so we had to do “code writing and vote getting” ourselves (See ABOUT).

Code writing and vote getting means that you gather data, develop relationships with like minded user-interests, find agreement where you can, then write proposals and defend them at NFPA 72 technical committee meetings for 3 to 6 years.  Prevailing in the Sturm und Drang of code development for 3 to 6 years should be within the means of business units of colleges and universities that have been in existence for 100’s of years.  The real assets under the stewardship of these business units are among the most valuable real assets on earth.

Consider the standard of care for inspection, testing and maintenance.  Our cross-cutting experience in over 100 standards suites allows us to say with some authority that, at best the IT&M tables of NFPA 72 Chapter 14 present easily enforceable criteria for IT&M of fire alarm and signaling systems.  At worst, Chapter 14 is a solid example of market-making by incumbent interests as the US standards system allows.   Many of the IT&M requirements can be modified for a reliability, or risk-informed centered maintenance program but fire and security shops in the education industry are afraid to apply performance standards because of risk exposure.   This condition is made more difficult in large universities that have their own maintenance and enforcement staff.  The technicians see opportunities to reduce IT&M frequencies — thereby saving costs for the academic unit facility managers — the enforcement/compliance/conformity/risk management professionals prohibit the application of performance standards.  They want prescriptive standards for bright line criteria to make their work easier to measure.

While we have historically focused on Chapter 14 we have since expanded our interest into communication technologies within buildings since technicians and public safety personnel depend upon them.  Content in Annex G — Guidelines for Emergency Communication Strategies for Buildings and Campuses — is a solid starting point and reflects of our presence when the guidance first appeared in the 2016 Edition.  We shall start with a review of the most recent transcript of the NFPA Technical Committee on Testing and Maintenance of Fire Alarm and Signaling Systems

NFPA 72 First Draft Meeting (A2024)

Williams College is a private liberal arts college located in Williamstown, Massachusetts, USA. Founded in 1793, it is one of the oldest institutions of higher education in the United States. The college was established through a bequest of Colonel Ephraim Williams Jr., a war hero who died in the Battle of Lake George during the French and Indian War. In his will, Colonel Williams left funds for the establishment of a free school on the condition that it be located in Williamstown.
