The iconic American “street food” traces its origin to 19th century German immigrants who brought frankfurters from their homeland.
In the 1860s, the term “hot dog” emerged in reference to these sausages being sold in buns at street carts. The popularity of hot dogs soared during the late 19th and early 20th centuries particularly at baseball games where the hot dog is virtually synonymous.at the sport.
In many college towns push cart hot dog vendors may be welcomed and even embraced as part of the local food scene. They can add variety and convenience for students, faculty, and staff by offering affordable and quick meal options. These towns may have regulations and policies in place to support and accommodate such vendors.
The case against hot dogs as a food primarily revolves around health concerns and potential risks associated with their consumption. Some of the key arguments include:
Processed meat and additives: Hot dogs are often made from processed meats that can contain additives, preservatives, and high levels of sodium. These additives, such as nitrates and nitrites, have been linked to increased risks of certain health issues, including cancer and heart disease.
High in unhealthy fats: Hot dogs are typically high in saturated and trans fats, which can contribute to elevated cholesterol levels and increase the risk of cardiovascular diseases.
Potential for contamination: There have been instances of foodborne illnesses associated with hot dogs, such as outbreaks of bacterial contamination, including E. coli or Listeria monocytogenes. Improper handling, storage, or undercooking can increase the risk of such contamination.
Allergens and dietary restrictions: Hot dogs often contain common allergens like wheat, soy, and dairy. Additionally, they may not be suitable for individuals with dietary restrictions or preferences, such as vegetarians, vegans, or those following specific religious or cultural dietary guidelines.
Environmental impact: The production and consumption of hot dogs contribute to environmental concerns. The meat industry, including processed meat production, is associated with greenhouse gas emissions, land degradation, and water pollution.
These arguments against hot dogs do not necessarily apply to all hot dogs or to every individual. Moderation, choosing healthier options, and considering individual dietary needs and preferences can help mitigate some of the concerns associated with hot dog consumption.

Today at 15:00 UTC we examine the technical literature about rainwater management in schools, colleges and universities — underfoot and on the roof. Lightning protection standards will also be reviewed; given the exposure of outdoor athletic activity and exterior luminaires.
We draw from previous standardization work in titles involving water, roofing systems and flood management — i.e. a cross-cutting view of the relevant standard developer catalogs. Among them:
American Society of Civil Engineers
American Society of Plumbing Engineers
ASHRAE International
ASTM International

The “lightning effect” seen in carnival tricks typically relies on a scientific principle known as the Lichtenberg figure or Lichtenberg figure. This phenomenon occurs when a high-voltage electrical discharge passes through an insulating material, such as wood or acrylic, leaving behind branching patterns resembling lightning bolts.
The process involves the creation of a temporary electric field within the material, which polarizes its molecules. As the discharge propagates through the material, it causes localized breakdowns, creating branching paths along the way. These branching patterns are the characteristic Lichtenberg figures.
In the carnival trick, a high-voltage generator is used to create an electrical discharge on a piece of insulating material, such as acrylic. When a person touches the material or a conductive object placed on it, the discharge follows the path of least resistance, leaving behind the branching patterns. This effect is often used for entertainment purposes due to its visually striking appearance, resembling miniature lightning bolts frozen in the material. However, it’s crucial to handle such demonstrations with caution due to the potential hazards associated with high-voltage electricity.
We are in the 2024–2026 ICC code development cycle, which is producing the 2027 editions of the International Codes. The 2024 IBC is the current published edition (released in 2023/early 2024). Chapter 15 (Roof Assemblies and Rooftop Structures) in the 2024 edition includes updates on topics like roof drainage, underlayment, wind resistance, occupiable rooftops, and aggregate-surfaced roofs.

FM Global is one of several organizations that produce technical and business documents that set the standard of care for risk management in education facilities. These standards — Property Loss Prevention Data Sheets — contribute to the reduction in the risk of property loss due to fire, weather conditions, and failure of electrical or mechanical equipment. They incorporate nearly 200 years of property loss experience, research and engineering results, as well as input from consensus standards committees, equipment manufacturers and others.
In July FM Global updated its standard FM 2510 Flood Abatement Equipment which should interest flood barrier manufacturers, standard authorities, industrial and commercial facilities looking to protect their buildings from riverline flooding conditions.
The following updates were proposed and mostly adopted:
Modifications to the opening barrier protocol to include water performance testing at lower depths;
Additional tests that apply to open-cellular rubber compounds (i.e., foam-type rubber) which are commonly used as gaskets on flood barriers need to be added to the Standard to sufficiently assess their quality;
Addition of adhesive testing. Many barrier designs use adhesives to bond the gasket material to the barrier. Adhesives are not addressed under the current protocol; Modify the flood abatement pump section to clarify approval of pump packages vs. wet-end only;
Additional requirements for electric drive and submersible flood pumps;
Modifications to backwater valve section to be inclusive of all types of “backwater valves” besides the traditional check valve.
Additional requirements for waterproofing products for building penetrations. Products in this category include collars, plugs, elastomeric seals, and types of putty.
This standard also contains test requirements for the performance of flood barriers, flood mitigation pumps, backwater valves, and waterproofing products for building penetrations, as well as an evaluation of the components comprising these products to assure reliability in the barrier’s performance.
While there are a number of noteworthy colleges and universities that have grown near rivers and lakes — twenty-five of which are listed HERE — severe weather and system failures present flooding risks to them all.
Another Data Sheet — I-40 Floods — was updated in October. Both Data Sheets are available for download at the link below:

Our use of the term “Educational Settlements” captures the self-contained energy of these places — kindergartens, classrooms, quads, dining halls, dorms, and nearby squares buzzing with student life amid broader higher-ed shifts like the “demographic cliff” (declining traditional enrollments), AI integration, skills-focused curricula, and financial pressures. (Related: Agora)
“…O chestnut tree;, great rooted blossomer, Are you the leaf, the blossom or the bold? O body swayed to music, O brightening glance, How can we know the dancer from the dance?”
We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority. We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.
Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter. We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting). Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets — typically the largest real asset owned by any US state and about 50 percent of its annual budget.
1. Leviathan. We track noteworthy legislative proposals in the United States 118th Congress. Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.
We do not advocate in legislative activity at any level. We respond to public consultations but there it ends.
We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture. Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C. It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

If you design or operate health care facilities, Standard 170 sets the minimum.
ANSI/ASHRAE/ASHE Standard 170 defines the minimum ventilation requirements for health care facilities and is developed in partnership with FGI and ASHE for adoption by code-enforcing agencies.
“Spring Night, Harlem River” | Ernest Lawson (1913)
Many school districts, colleges and universities are affected by the flooding in the Central United States this week; inspiration enough for revisiting the technical and management codes and standards to avoid and/or mitigate damages. The consensus documents developed by the American Society of Civil Engineers (ASCE) and its affiliate Structural Engineering institute (ASCE-SEI) — should appear in the design guidelines given to professional services firms retained by the facility construction, operations and maintenance workgroups.
The relevant standard in this space is ASCE 24 Flood Resistant Design which is developed jointly with the ASCE-SEI and technical committees of the International Code Council. Apparently the 2014 Edition is the latest edition so that means that during 2019 will be the beginning of another revision cycle (according to ANSI requirements for 5-year revisions/re-affirmations).
From the ASCE 24 prospectus:
Flood Resistant Design and Construction, ASCE/SEI 24-14, provides minimum requirements for design and construction of structures located in flood hazard areas and subject to building code requirements. Identification of flood prone structures is based on flood hazard maps, studies, and other public information. This standard applies to new structures, including subsequent work, and to work classified as substantial improvement of existing structures that are not historic. Standard ASCE/SEI 24-14 introduces a new concept, Flood Design Class, that bases requirements for a structure on the risk associated with unacceptable performance.
The standard includes requirements for the following: basic siting and design and construction requirements for structures in flood hazard areas; minimum elevations for the lowest floor, flood damage-resistant materials, and floodproofing measures, each tied to a structure’s Flood Design Class; structures in high risk flood hazard areas subject to flooding associated with alluvial fans, flash floods, mudslides, erosion, high velocity flow, coastal wave action, or ice jams and debris; structures in coastal high hazard areas (V Zones) and Coastal A Zones; flood damage-resistant materials; dry floodproofing and wet floodproofing; attendant utilities and equipment, including electrical service, plumbing systems, mechanical/HVAC systems, and elevators; building access; and miscellaneous construction, including decks and porches, concrete slabs, garages and carports, accessory storage structures, chimneys and fireplaces, pools, and tanks. A detailed commentary containing explanatory and supplementary information to assist users of the standard is included for each chapter.
Standard ASCE/SEI 24-14 updates and replaces the previous Standard, ASCE/SEI 24-05. It provides essential guidance on design and construction to structural engineers, design professionals, code officials, floodplain managers, and building owners. The standard is adopted by reference in model building codes.
Keep in mind that model building codes usually change on a 3-year cycle while this standard changes on a 5-year cycle (though intermediates changes can, and do, happen).

Recap of the May meetings of the Industrial & Commercial Power Systems Conference in Las Vegas. The conference ended the day before the beginning of the 3-day Memorial Day weekend in the United States so we’re pressed for time; given all that happened.
We can use our last meeting’s agenda to refresh the status of the issues.
We typically break down our discussion into the topics listed below:
Codes & Standards:
While IAS/I&CPS has directed votes on the NEC; Mike is the only I&CPS member who is actually submitting proposals and responses to codes and standards developers to the more dominant SDO’s — International Code Council, ASHRAE International, UL, ASTM International, IEC & ISO. Mike maintains his offer to train the next generation of “code writers and vote getters”
Performance-based building premises feeder design has been proposed for the better part of ten NEC revision cycles. The objective of these proposals is to reduce material, labor and energy waste owed to the branch and feeder sizing rules that are prescriptive in Articles 210-235. Our work in service and lighting branch circuit design has been largely successful. A great deal of building interior power chain involves feeders — the network upstream from branch circuit panels but down stream from building service panel.
Our history of advocating for developing this approach, inspired by the NFPA 101 Guide to Alternative Approaches to Life Safety, and recounted in recent proposals for installing performance-based electrical feeder design into the International Building Code, appears in the link below:
Access to this draft paper for presentation at any conference that will receive it — NFPA, ICC or IEEE (or even ASHRAE) will be available for review at the link below:
NFPA 110 Definitions of Public Utility v. Merchant Utility
NFPA 72 “Definition of Dormitory Suite” and related proposals
Buildings:
Renovation economics, Smart contracts in electrical construction. UMich leadership in aluminum wiring statements in the NEC should be used to reduce wiring costs.
This paper details primary considerations in estimating the life cycle of a campus medium voltage distribution grid. Some colleges and universities are selling their entire power grid to private companies. Mike has been following these transactions but cannot do it alone.
Variable Architecture Multi-Island Microgrids
District energy:
Generator stator winding failures and implications upon insurance premiums. David Shipp and Sergio Panetta. Mike suggests more coverage of retro-fit and lapsed life cycle technicals for insurance companies setting premiums.
Reliability:
Bob Arno’s leadership in updating the Gold Book.
Mike will expand the sample set in Table 10-35, page 293 from the <75 data points in the 1975 survey to >1000 data points. Bob will set up meeting with Peyton at US Army Corps of Engineers.
Reliability of merchant utility distribution systems remains pretty much a local matter. The 2023 Edition of the NESC shows modest improvement in the vocabulary of reliability concepts. For the 2028 Edition Mike submitted several proposals to at least reference IEEE titles in the distribution reliability domain. It seems odd (at least to Mike) that the NESC committees do not even reference IEEE technical literature such as Bob’s Gold Book which has been active for decades. Mike will continue to propose changes in other standards catalogs — such as ASTM, ASHRAE and ICC — which may be more responsive to best practice assertions. Ultimately, improvements will require state public utility commission regulations — and we support increases in tariffs so that utilities can afford these improvements.
Mike needs help from IEEE Piscataway on standard WordPress theme limitations for the data collection platform.
Mike will update the campus power outage database.
Healthcare:
Giuseppe Parise’s recent work in Italian power grid to its hospitals, given its elevated earthquake risk. Mike’s review of Giuseppe’s paper:
Mike and David Shipp will prepare a position paper for the Harvard Healthcare Management Journal on reliability advantages of impedance grounding for the larger systems.
The Internet of Bodies
Forensics:
Giuseppe’s session was noteworthy for illuminating the similarity and differences between the Italian and US legal system in handling electrotechnology issues.
Mike will restock the committee’s library of lawsuits transactions.
Ports:
Giuseppe updates on the energy and security issues of international ports. Mike limits his time in this committee even though the State of Michigan has the most fresh water international ports in the world.
A PROPOSED GUIDE FOR THE ENERGY PLAN AND ELECTRICAL INFRASTRUCTURE OF A PORT
Other:
Proposals to the 2028 National Electrical Safety Code: Accepted Best Practice, exterior switchgear guarding, scope expansion into ICC and ASHRAE catalog,
Apparently both the Dot Standards and the Color Books will continue parallel development. Only the Gold Book is being updated; led by Bob Arno. Mike admitted confusion but reminded everyone that any references to IEEE best practice literature in the NFPA catalog, was installed Mike himself (who would like some backup help)
Mike assured Christel Hunter (General Cable) that his proposals for reducing the 180 VA per-outlet requirements, and the performance-base design allowance for building interior feeders do not violate the results of the Neher-McGrath calculation used for conductor sizing. All insulation and conducting material thermal limits are unaffected.
Other informal discussions centered on the rising cost of copper wiring and the implications for the global electrotechnical transformation involving the build out of quantum computing and autonomous vehicles. Few expressed optimism that government ambitions for the same could be met in any practical way.
Are students avoiding use of Chat GPT for energy conservation reasons? Mike will be breaking out this topic for a dedicated standards inquiry session:
“Benjamin Franklin Drawing Electricity from the Sky” 1816 Benjamin West
Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.
He used a kite and a key to demonstrate that lightning was a form of electricity.
This experiment marked an important milestone in understanding the nature of electricity
and laid the foundation for the development of lightning rods and other lightning protection systems.
Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems
This document shall cover traditional lightning protection system installation requirements for the following: (1) Ordinary structures (2) Miscellaneous structures and special occupancies (3) Heavy-duty stacks (4) Structures containing flammable vapors, flammable gases, or liquids with flammable vapors (5) Structures housing explosive materials (6) Wind turbines (7) Watercraft (8) Airfield lighting circuits (9) Solar arrays
This document shall address lightning protection of the structure but not the equipment or installation requirements for electric generating, transmission, and distribution systems except as given in Chapter 9 and Chapter 12.
(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power. Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)
This document shall not cover lightning protection system installation requirements for early streamer emission systems or charge dissipation systems.
“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height
“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.
Related grounding and bonding requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code. This standard does not establish evacuation criteria.

The current edition is dated 2023 and, from the transcripts, you can observe concern about solar power and early emission streamer technologies tracking through the committee decision making. Education communities have significant activity in wide-open spaces; hence our attention to technical specifics.
Public input on the 2026 revision is receivable until 1 June 2023.
We always encourage our colleagues to key in their own ideas into the NFPA public input facility (CLICK HERE). We maintain NFPA 780 on our Power colloquia which collaborates with IEEE four times monthly in European and American time zones. See our CALENDAR for the next online meeting; open to everyone.
Lightning flash density – 12 hourly averages over the year (NASA OTD/LIS) This shows that lightning is much more frequent in summer than in winter, and from noon to midnight compared to midnight to noon.

Didn't really plan for all possibilities, did they. 🤓
Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:
Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.
Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.
Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.
Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.
Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.
Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.
Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.
The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance.
Building, operating, and maintaining athletic scoreboards requires a range of technologies, including hardware and software components. These are central features in nearly every athletic event, governing the state of play and attendee response.
Scoreboard Hardware: A range of hardware components, including display panels, control consoles, sound systems, and wiring, is necessary to build an athletic scoreboard. While there are no universal standards for LED displays in athletic scoreboards, but there is a common vocabulary used by manufacturers and installers follow to ensure quality, performance, and safety:
Brightness and Contrast: LED displays should be bright enough to be visible from a distance, but not so bright that they cause glare or eye strain. The contrast ratio between the LED display and the surrounding environment should be optimized for visibility.
Pixel Density and Resolution: The pixel density and resolution of an LED display should be appropriate for the size of the scoreboard and the viewing distance. Higher pixel density and resolution can improve the clarity and detail of the scoreboard display.
Color Accuracy: Athletic scoreboards often display team colors and logos, so color accuracy is important. LED displays should be capable of reproducing colors accurately and consistently.
Refresh Rate: The refresh rate of an LED display refers to how quickly the display can update its image. A higher refresh rate can reduce motion blur and improve the clarity of fast-moving action on the scoreboard.
Environmental Factors: Athletic scoreboards are often exposed to outdoor elements such as sunlight, rain, and extreme temperatures. LED displays should be designed and manufactured to withstand these environmental factors and maintain their performance over time.
Safety: Athletic scoreboards should be designed and installed to minimize the risk of injury to players or spectators. This may include factors such as the height and location of the scoreboard, the durability of the display panels, and the strength of mounting hardware.
Wireless Communications: Many modern athletic scoreboards use wireless communication systems to connect the scoreboard control console to the scoreboard display. This allows for greater flexibility in installation and reduces the need for cabling.
LED Technology: LED technology has revolutionized athletic scoreboards in recent years. LED displays offer superior brightness, color accuracy, and energy efficiency compared to traditional scoreboards but must conform to local night-sky regulations.
Power Management Systems: Athletic scoreboards require significant amounts of power to operate, and efficient power management systems are necessary to ensure reliable and continuous operation. Maintaining temperatures — heating and cooling within specification — is a priority for maximum operable life.
Maintenance and Diagnostic Tools: To maintain and troubleshoot athletic scoreboards, specialized tools and software are necessary. This may include diagnostic software, specialized cables, and other testing equipment.
Overall, the technologies required to build, operate, and maintain athletic scoreboards are diverse and constantly evolving. A range of specialized hardware and software components, as well as skilled technicians, are necessary to ensure that athletic scoreboards remain functional and reliable.
