We have advocated education community risk management concepts since 2007; primarily in NFPA Standard 1300 — Standard on Community Risk Assessment and Community Risk Reduction Plan Development (formerly NFPA 1600). The content of this title is close-coupled with FEMA’s National Incident Management System.
Recently the National Fire Protection Association Standards Council moved to consolidate its community risk management titles as described below.
“NFPA 1660 is in a custom cycle due to the Emergency Response and Responder Safety Document Consolidation Plan (consolidation plan) as approved by the NFPA Standards Council. As part of the consolidation plan, NFPA 1660 (combining Standards NFPA 1600, NFPA 1616, and NFPA 1620) is open for public input with a closing date of November 13, 2020.”
Discussion about school and university security are noteworthy.
As described on its title page, this product will be reconfigured as NFPA 1660 Standard on Community Risk Assessment, Pre-Incident Planning, Mass Evacuation, Sheltering, and Re-entry Programs. The title suggests that NFPA 1660 is being developed to meet market need for conformance and teaching tools. You may track movement in the concepts in the links below; many of them administrative:
NFPA 1660 will likely require one or two more revision cycles to stabilize
Public consultation on the Second Draft (NITMAM) closes September 9th. You may submit public input directly to NFPA by CLICKING HERE. We will have hosted several Security colloquia ahead of this deadline during which we will drill into technical and policy specifics.

The recent undetected introduction and rapid spread of foot and mouth disease in the United Kingdom highlights the importance of the integration of effective biosecurity practices in every livestock operation within the US. Showing and exhibiting animals presents a risk for the spread of foreign or domestic infectious disease.
Infectious diseases such as respiratory disease, contagious mastitis and bovine viral diarrhea, can present signs within a relatively short time frame, whereas Johne’s disease may not show signs for years after exposure. Taking the precautions listed below before, during and after fairs can help decrease the exposure to infectious disease.

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
Construction Specifications Institute (Division 7 Thermal and Moisture Protection)

“Rainbow Connection”
“Tough Call” | Norman Rockwell 1949
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:

“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.
Blueberry pancakes have deep roots in the American Midwest, blending Native American traditions with 20th-century agricultural innovation. Indigenous peoples in the Great Lakes region had long used wild blueberries — abundant in Michigan, Wisconsin, and Illinois — as a nutritious food source, mixing them into cornmeal flatbreads and porridges. European settlers adopted these berries into their pancake recipes by the 19th century. However, blueberry pancakes as a widespread breakfast staple only emerged in the early 1900s. The breakthrough came after 1916, when commercial highbush blueberry cultivation began in New Jersey and quickly spread to Midwest states.
Happy #NationalFarmersDay! Thank you to the hard working Illinois farmers and ranchers who work to feed a hungry world.

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.
Join us today at 11 AM/ET (15:00 UTC) when we review best practice literature. Open to everyone. Use the login credentials at the upper right of our home page. This topic is also tracked by experts in the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in Central European and American time zones and is also open to everyone.
Here we shift our perspective 120 degrees to understand the point of view of the Producer interest in the American national standards system (See ANSI Essential Requirements). The title of this post draws from the location of US and European headquarters. We list proposals by a successful electrical manufacturer for discussion during today’s colloquium:
2026 National Electrical Code
CMP-1: short circuit current ratings, connections with copper cladded aluminum conductors, maintenance to be provided by OEM, field markings
CMP-2: reconditioned equipment, receptacles in accessory buildings, GFCI & AFCI protection, outlet placement generally, outlets for outdoor HVAC equipment(1)
(1) Here we would argue that if a pad mount HVAC unit needs service with tools that need AC power once every 5-10 years then the dedicated branch circuit is not needed. Many campuses have on-site, full-time staff that can service outdoor pad mounted HVAC equipment without needing a nearby outlet. One crew — two electricians — will run about $2500 per day to do anything on campus.
CMP-3: No proposals
CMP-4: solar voltaic systems (1)
(1) Seems reasonable – spillover outdoor night time lighting effect upon solar panel charging should be identified.
CMP-5: Administrative changes only
CMP-6: No proposals
CMP-7: Distinction between “repair” and “servicing”
CMP-10: Short circuit ratings, service disconnect, disconnect for meters, transformer secondary conductor, secondary conductor taps, surge protective devices, disconnecting means generally, spliced and tap conductors, more metering safety, 1200 ampere threshold for arc reduction technology, reconditioned surge equipment shall not be permitted, switchboard short circuit ratings
