Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard

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:

  1. Lightning Detection Systems: Many sports facilities are equipped with lightning detection systems that can track lightning activity in the area. These systems use sensors to detect lightning strikes and provide real-time information on the proximity and severity of the lightning threat. When lightning is detected within a certain radius of the sports facility, it can trigger a delay or suspension of outdoor sports activities.
  2. Lightning Distance and Time Rules: A common rule of thumb used in outdoor sports is the “30-30” rule, which states that if the time between seeing lightning and hearing thunder is less than 30 seconds, outdoor activities should be suspended, and participants should seek shelter. The idea is that lightning can strike even when it is not raining, and thunder can indicate the proximity of lightning. Once the thunder is heard within 30 seconds of seeing lightning, the delay or suspension should be implemented.
  3. Local Weather Authority Guidelines: Local weather authorities, such as the National Weather Service in the United States, may issue severe weather warnings that include lightning information. Sports organizations may follow these guidelines and suspend outdoor sports activities when severe weather warnings, including lightning, are issued for the area.
  4. Sports-Specific Guidelines: Some sports may have specific guidelines for lightning delays or suspensions. For example, golf often follows a “Play Suspended” policy, where play is halted immediately when a siren or horn is sounded, and players are required to leave the course and seek shelter. Other sports may have specific rules regarding how long a delay should last, how players should be informed, and when play can resume.

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.

Noteworthy: NFPA titles such as NFPA 780 and NFPA 70 Article 242 deal largely with wiring safety, informed by assuring a low-resistance path to earth (ground)

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.

There are several specific problems that swimming pool overhead lighting aims to solve:

  1. Visibility: Swimming pool overhead lighting is designed to improve visibility in and around the pool. This is important for safety reasons, as it helps swimmers see where they are going and avoid obstacles or hazards.
  2. Aesthetics: Overhead lighting can enhance the appearance of the swimming pool by creating a visually appealing atmosphere. This is especially important for commercial pools where the aesthetics can be an important factor in attracting customers.
  3. Functionality: Overhead lighting can provide additional functionality by allowing the pool to be used during evening hours or in low light conditions. This can increase the usability of the pool and make it more appealing to users.
  4. Energy efficiency: Modern overhead pool lighting solutions are designed to be energy-efficient, reducing the overall energy consumption and operating costs of the pool.
  5. Longevity: Overhead pool lighting must be designed to withstand exposure to water, chlorine, and other harsh chemicals, as well as exposure to the elements. The lighting system must be durable and reliable to ensure longevity and prevent costly repairs or replacements.

Overall, swimming pool overhead lighting is an important component of a safe, functional, and visually appealing pool. It provides illumination for visibility, enhances aesthetics, and improves functionality, while also being energy-efficient and durable.

After athletic arena life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play. For almost all athletic facilities,  the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

During water sport season the document linked below provides information to illumination designers and facility managers:

NCAA Best Lighting Practices

Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States.   We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises.  We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.

See our CALENDAR for our next colloquium on Sport facility codes and standards  We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

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
