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.

A novel smart energy management system in sports stadiums

 

A novel smart energy management system in sports stadiums

Shady S. Refaat, et al

Texas A&M University at Qatar, Qatar Foundation, Doha, Qatar

Professional and collegiate sport venues consume huge electrical energy. Therefore, a smart management of their electric energy is essential for significant energy saving. Accordingly, this paper proposes a novel embedded real-time, smart, and active energy management system to monitor and efficiently manage such huge and typically uncontrolled energy for minimizing energy consumption and cost per day while considering spectators preferences, comfort level in behavioral modification program, and health aspects. This will provide an opportunity for spectators to reduce energy consumption and improve energy efficiency while considering healthcare concept. In addition, the proposed energy management system is equipped with embedded tools to collect and monitor energy information for each stadium’s area. The data are processed and fed to the artificial neural network algorithm that is used for managing and controlling stadium loads. This strategy does not require any change in the conventional stadium electrical panel. The proposed online algorithm yields to improve the overall grid efficiency, reliability, and increase awareness of the importance of energy conservation. Real-Time implementation of the concept is demonstrated and analyzed.

“The voice of the intellect is a soft one,

but it does not rest until it has gained a hearing.”

— Sigmund Freud

 

The education industry provides a large market for occupancy classes — athletic stadiums, student assembly spaces, performance theaters, large lecture halls– that depend upon effective audio systems*.   To an unexpected degree the structural engineering, specification of materials and electrical system design and operation is informed by acoustical considerations.  So does the integration of fire safety and mass notification systems into normal state enterprises so it is wise to follow and, ideally, participate in leading practice discovery and promulgation of audio standards.

The Audio Engineering Society — one of the first names in this space — has a due process platform that welcomes public participation.   All of its standards open for public comment completed their revision cycle mid-November as can be seen on its standards development landing page below:

AES Standards Development

Note that AES permits access to those revision even after the comment deadline.  You are encouraged to communicate directly with the Direct communication with the standards staff at Audio Engineering Society International Headquarters, 551 Fifth Avenue, Suite 1225, New York NY 10176,  Tel: +1 212 661 8528

We keep the AES suite on the standing agenda of our periodic Lively Arts teleconference.  See our CALENDAR for the next online meeting.

This facility class is one of most complex occupancy classes in education facilities industry so we also collaborate with experts active in the IEEE Education & Healthcare Facilities Committee. Much of the AES suite references, and borrows from, International Electrotechnical Commission system integration and interoperability standards.   The IEEE E&H committee meets online again four times monthly in European and American time zones.  The meeting dates are available on the IEEE E&H website

Automated Sports Court Drawing Bot

 

Arduino based Automated Sports Court Drawing Bot

Rajesh Kannan Megalingam, et. al

Department of Electronics and Communication Engineering, Amrita Vishwa Vidyapeetham, Amritapuri, India

Stadium maintenance staff are one of those people who work hard to maintain the court correctly. One of the items that often require rework is the lines drawn on the court for maintenance of track or boundaries or even the entire court when it is football stadium etc. Besides, for indoor stadiums that host volleyball, basketball, tennis, etc., lines need to be drawn. Redrawing the court after each match is one of the major problems of concern. In such a scenario, a system is proposed that can draw the court lines autonomously. The objective of this research work is to present a design of an autonomous sports court drawing bot that can draw the linear lines automatically which can aid in the maintenance work of the sports stadium.

Today we review the literature informing the safety and sustainability agenda of sport enterprises in education communities; in the United States at least — one of the last, if not the last, meritocracies in academia at large.  School districts have hundreds of playgrounds, gymnasiums and playgrounds.  Athletic departments are very visible enterprises; particularly at large colleges and universities with varsity teams that have long been “farm clubs” for professional sport companies.

This facility class is far more complicated (technically) than classroom facilities; closer to research and healthcare delivery enterprises in risk aggregation when you consider how many people are involved as spectators.  This facility class resides proximate to the actuality of rehabilitated or additional sanitary facilities which we cover in our periodic Water 200 colloquia.

Throughout 2024 we will break down our coverage thus:

Winter Sport

Field sport

Court sport

Water sport

We will also explore best practice codes and standards for recreational activity:

Rock Climbing: In the sport of rock climbing, technical skills, grip strength, and body positioning are crucial for both indoor and outdoor climbing. Climbers must navigate a variety of challenging terrains and routes.

Fencing: Fencing requires quick thinking, precise footwork, and precise blade work. Fencers need to anticipate their opponent’s moves and respond with well-timed and accurate attacks and parries.

Quidditch:  Once a fictional sport; now widely played as “Quadball”.

Readings / Sport, Culture & Society

* Eugen Rosenstock-Huessy (1888-1973) was a German-American philosopher, social thinker, and linguist. He was born in Berlin, Germany, and was raised in a Jewish family. Rosenstock-Huessy studied law, theology, and philosophy in Berlin, but his studies were interrupted by World War I. During the war, he served as a lieutenant in the German army and was taken prisoner by the Russian army.

After the war, Rosenstock-Huessy continued his studies and became a professor of law and sociology at the University of Breslau. He was forced to leave Germany in 1933 because of his opposition to the Nazi regime, and he emigrated to the United States. In the United States, Rosenstock-Huessy continued his academic work and became a professor of social philosophy at Dartmouth College in New Hampshire.

Rosenstock-Huessy’s work focused on the role of language in shaping human culture and social institutions. He believed that language was not just a means of communication but was also a way of creating and organizing social relations. His ideas had a significant influence on the development of linguistic phenomenology and hermeneutics.

Some of his notable works include “Out of Revolution: Autobiography of Western Man”, “Speech and Reality”, and “The Christian Future, or the Modern Mind Outrun”.
