Thunderstorm | Shelter (Building: 30/30 Rule)
The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:
It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.
There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.
Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.

FCC Proposes to Modify Technical Rules for Digital FM Stations
Our Office of Engineering & Technology maintains the U.S. Table of Frequency Allocations, manages Experimental Licensing & Equipment Authorization programs, regulates operation of unlicensed devices, and conducts engineering & technical studies. https://t.co/MATs1ThyxL #FCC101

The FCC is the United States’ primary authority for communications laws, regulation and technological innovation. We provide a link to the August 3rd meeting during which time rules for Digital FM Radio and Non-Federal Spectrum Usage were discussed. Campus Security Radio, National Public Radio and Student Radio are central features of education community culture and safety and are typically available when the internet is not.

Abstract. The analysis presented in this paper indicates that the FM radio spectrum is underutilized in the areas of the continental United States that have a population of 100000 or less. These locations have vacant FM radio spectrum of at least 13 MHz with sufficient spectrum spacing between adjacent FM radio channels. The spectrum spacing provides the required bandwidth for data transmission and provides enough bandwidth to minimize interference introduced by neighboring predicted and unpredicted FM radio stations and other low-power short-range Internet of Thing (IoT) devices. To ensure that low-power short-range IoT devices maintain reliable communications vacant radio spectrum, such as the FM radio spectrum in these areas, will need to be used through cognitive radio.

Fish and Chips and the British Working Class, 1870-1930
“Fish and chips was in many ways the pioneer fast-food industry. It became an essential component of working-class diet and popular culture in parts of London, and over wide areas of industrial midland and northern England and southern Scotland, in the early decades of the twentieth century…I propose to argue that the fish and chip trade was not only important enough in itself to justify sustained historical analysis, but also that it provides a useful vantage point for examining important changes in British society more generally.”

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)
Public Emergency Reporting Systems (SIG-PRS) First Draft
Public comment of the First Draft of the 2025 Edition is receivable until May 31, 2023. As always, we encourage direct participation in the NFPA process by workpoint experts with experience, data and even strong opinions about shortcomings and waste in this discipline. You may key in your proposals on the NFPA public input facility linked below:
You will need to set up a (free) NFPA TerraView account. Alternatively, you may join us any day at 11 AM US Eastern time or during our Prometheus or Radio colloquia. See our CALENDAR for the online meeting.

WASHINGTON, March 18, 2020—The Federal Communications Commission today announced important changes to the Rural Health Care (RHC) and E-Rate programs that will make it easier for broadband providers to support telehealth and remote learning efforts during the coronavirus pandemic. Specifically, the FCC’s Wireline Competition Bureau has waived the gift rules until September 30, 2020 to enable service providers to offer, and RHC and ERate program participants to solicit and accept, improved connections or additional equipment for telemedicine or remote learning during the coronavirus outbreak.
