“View of the Colosseum” 1747 Giovanni Paolo Panini

 

Play is the making of civilization—how one plays the game

more to the point than whether the game is won or lost.

 

We follow development of best practice literature for spectator seating structures produced by the International Code Council,  the National Fire Protection Association (NFPA 102),  the American Society of Civil Engineers Structural Engineering Institute (ASCE SEI-7).  There are also federal regulations promulgated by the Consumer Product Safety Commission.  (Note that some of the regulations were inspired by the several regional building code non-profits before the International Code Council was formed in year ~ 2000)

The parent standard from the International Code Council is linked below:

ICC 300 Standard on Bleachers, Folding and Telescopic Seating, and Grandstands

The development of this standard is coordinated with the ICC Group A Codes.  We have tracked concepts in it previous revisions; available in the link below.

“A Dance to the Music of Time” 1640 Nicolas Poussin

 

 

“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:

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

“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.

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.

‘The Barber of Seville’ by Luis Alvarez Catalá

Codes, standards and licensing for barbering schools and cosmetology academies are governed by local regulations; or local adaptations of national standards-setting organizations.  

Northern Michigan University | Marquette County

Building Codes

  1. Minimum Floor Space
    • Schools must provide adequate space for instruction and practice. For example, California requires a minimum of 3,000 square feet for cosmetology schools (which often include barbering), with at least 2,000 square feet dedicated to working, practice, and classroom areas. Additional space (e.g., 30 square feet per student beyond the first 50) may be required as enrollment increases.
    • Rooms for practical work must be sized appropriately, such as at least 14 feet wide for one row of barber chairs or 20 feet for two rows (California standard).
  2. Ceiling Height
    • Practice and classroom areas often require a minimum ceiling height, such as 9 feet, to ensure proper ventilation and comfort (e.g., California Building Code).
  3. Floor Finish
    • Floors in areas like restrooms or workspaces must be made of nonabsorbent materials (e.g., tile) to facilitate cleaning and maintain hygiene.
  4. Separation from Other Uses
    • Barbering schools must be distinct entities, not combined with residential spaces or unrelated businesses (e.g., Nevada’s NAC 643.500).
  5. Compliance with Local Building and Zoning Codes
    • Facilities must adhere to local ordinances for construction, occupancy, and zoning, ensuring the building is structurally sound and legally permitted for educational use (e.g., Virginia’s 18VAC41-20-270).
  6. Accessibility
    • Buildings must comply with accessibility standards (e.g., ADA in the U.S.), providing ramps, wide doorways, and accessible restrooms.

Safety

  1. Fire Safety
    • Compliance with the State Uniform Fire Prevention and Building Code (e.g., New York’s 19 NYCRR Parts 600-1250) or equivalent, including fire exits, extinguishers, and alarms.
    • Emergency exits must be clearly marked and unobstructed.
  2. Electrical Safety
    • All electrical equipment (e.g., clippers, dryers) must be regularly inspected (e.g., PAT testing in some regions) to prevent shocks or fires.
  3. Ventilation and Temperature Control
    • Adequate ventilation systems are required to maintain air quality and a safe working temperature, protecting students and instructors from fumes or overheating.
  4. First Aid and Emergency Preparedness
    • A stocked first aid kit must be available, and schools should have protocols for handling accidents or emergencies.
  5. Equipment Safety
    • Tools and workstations (e.g., chairs, sinks) must be maintained in good condition to prevent injuries. Hazardous tools like razor-edged implements for callus removal are often prohibited (e.g., California regulations).
  6. Occupational Safety
    • Compliance with OSHA (Occupational Safety and Health Administration) or state equivalents, such as Virginia’s Department of Labor and Industry standards, to protect against workplace hazards like chemical exposure or repetitive strain.


Hygiene

  1. Sanitation of Facilities
    • Schools must be kept clean and sanitary at all times, including floors, walls, furniture, and workstations (e.g., Virginia’s 18VAC41-20-270).
  2. Disinfection of Tools
    • Each student or instructor must have a wet disinfection unit at their station for sterilizing reusable tools (e.g., combs, shears) after each use. Disinfectants must be EPA-registered and bactericidal, virucidal, and fungicidal.
    • Single-use items (e.g., razor blades) must be discarded after each client in a labeled sharps container.
  3. Hand Hygiene
    • Practitioners must wash hands with soap and water or use hand sanitizer before services (e.g., Texas Rule 83.102).
  4. Client Protection
    • Sanitary neck strips or towels must be used to prevent capes from contacting clients’ skin directly (e.g., California regulations).
    • Services cannot be performed on inflamed, broken, or infected skin, and practitioners with such conditions on their hands must wear gloves.
  5. Product Safety
    • Cosmetic products containing FDA-banned hazardous substances are prohibited, and all products must be used per manufacturer instructions (e.g., Virginia’s 18VAC41-20-270).
  6. Waste Management
    • Proper disposal of soiled items (e.g., hair clippings) and hazardous waste (e.g., blades) is required, often daily or after each client.
  7. Health Department Compliance
    • Schools must follow state health department guidelines and report inspection results (e.g., Virginia requires reporting to the Board of Barbers and Cosmetology).
  8. Self-Inspection
    • Annual self-inspections must be documented and retained for review (e.g., Virginia mandates keeping records for five years).


Discussion

  • State-Specific Variations: Always consult your state’s barbering or cosmetology board for exact requirements. For instance, Texas (TDLR) emphasizes signage and licensing display, while California focuses on detailed sterilization methods.
  • Inspections: Schools are subject to regular inspections by state boards or health departments to ensure compliance.
