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.
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:
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.
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.
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.
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.
Codes, standards and licensing for barbering schools and cosmetology academies are governed by local regulations; or local adaptations of national standards-setting organizations.
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).
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).
Floor Finish
Floors in areas like restrooms or workspaces must be made of nonabsorbent materials (e.g., tile) to facilitate cleaning and maintain hygiene.
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).
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).
Accessibility
Buildings must comply with accessibility standards (e.g., ADA in the U.S.), providing ramps, wide doorways, and accessible restrooms.

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.
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.
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.
First Aid and Emergency Preparedness
A stocked first aid kit must be available, and schools should have protocols for handling accidents or emergencies.
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).
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.

Schools must be kept clean and sanitary at all times, including floors, walls, furniture, and workstations (e.g., Virginia’s 18VAC41-20-270).
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.
Hand Hygiene
Practitioners must wash hands with soap and water or use hand sanitizer before services (e.g., Texas Rule 83.102).
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.
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).
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.
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).
Self-Inspection
Annual self-inspections must be documented and retained for review (e.g., Virginia mandates keeping records for five years).

Quality lighting enhances our ability to see and interpret the world around us, supporting our sense of well-being, and improving our capability to communicate with each other….”
Illumination technologies run about 30 percent of the energy load in a building and require significant human resources at the workpoint — facility managers, shop foremen, front-line operations and maintenance personnel, design engineers and sustainability specialists. The IES has one of the easier platforms for user-interest participation:
Because the number of electrotechnology standards run in the thousands and are in continual motion* we need an estimate of user-interest in any title before we formally request a redline because the cost of obtaining one in time to make meaningful contributions will run into hundreds of US dollars; apart from the cost of obtaining a current copy.
We maintain the IES catalog on the standing agendas of our Electrical, Illumination and Energy colloquia. Additionally, we collaborate with experts active in the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones; all colloquia online and open to everyone.

Abstract. The recently introduced continuous Skip-gram model is an efficient method for learning high-quality distributed vector representations that capture a large number of precise syntactic and semantic word relationships. In this paper we present several extensions that improve both the quality of the vectors and the training speed. By subsampling of the frequent words we obtain significant speedup and also learn more regular word representations. We also describe a simple alternative to the hierarchical softmax called negative sampling.
An inherent limitation of word representations is their indifference to word order and their inability to represent idiomatic phrases. For example, the meanings of “Canada” and “Air” cannot be easily combined to obtain “Air Canada”. Motivated by this example, we present a simple method for finding phrases in text, and show that learning good vector representations for millions of phrases is possible.
Large Language Models and Infrastructure Technical Standards
Large Language Models (LLMs) are poised to significantly accelerate and reshape the development of infrastructure standards — including engineering codes, technical specifications for civil works, transportation, energy grids, water systems, and related Standards Development Organization (SDO) processes at ASTM, IEEE, ASABE, ISO, and similar bodies. This connection traces back to foundational ideas in distributed representations (Hinton et al., Mikolov’s Word2Vec) that powered the transformer revolution, which in turn enabled modern LLMs and the shift from passive generative AI to active, goal-directed agentic AI.
While LLMs will not replace human expertise, consensus-building, or rigorous validation, they will transform traditionally slow, document-heavy workflows into faster, more collaborative, and data-driven processes.
1. Faster Drafting, Summarization, and Gap Analysis
LLMs can rapidly summarize lengthy documents, extract key requirements, identify inconsistencies across related standards, and generate initial draft sections or comparison tables. This is especially valuable for reviewing historical codes, research papers, regulations, and stakeholder inputs.
Infrastructure example: In renewable energy permitting or grid interconnection standards, LLMs excel at processing complex environmental impact statements and regulatory texts to accelerate reviews.
2. Enhanced Requirements Engineering and Consistency Checking
LLMs support formal requirements extraction, flag ambiguities, suggest measurable criteria, and translate between domains. They help maintain alignment between textual standards and digital implementations such as Building Information Modeling (BIM) or simulation tools.
3. Improved Accessibility, Education, and Stakeholder Participation
LLMs make standards more usable by generating plain-language explanations, FAQs, examples, and tailored training materials. They lower barriers for broader participation in SDO committees by helping non-experts understand and contribute to drafts.
4. Domain-Specific Applications in Infrastructure
Civil, Structural & Agricultural Engineering: Design ideation, safety analysis, and updating standards for new materials and climate resilience.
Permitting & Compliance: Summarizing environmental documents and speeding up infrastructure deployment.
Interoperability & Testing: Verification support for software-heavy systems such as smart grids and autonomous infrastructure.
5. Broader Process Changes for SDOs
Zero-draft acceleration for preliminary stakeholder review
Continuous monitoring for maintenance and timely updates
Multi-agent LLM systems for parallel virtual expert review before human consensus
Limitations and Important Caveats
“Hallucinations” & Validation: Outputs must always be human-verified, especially in safety-critical areas. Domain-specific fine-tuning and retrieval-augmented generation (RAG) help but are not foolproof.
Bias, Copyright & Accountability: Standards demand traceability and consensus; LLMs can introduce subtle biases or IP concerns.
Not a Full Replacement: Human judgment remains essential for risk assessment, ethics, and real-world tradeoffs.
Expect 2–5× faster iteration on drafts, superior knowledge management, and more adaptive standards. Early adopters using LLM assisted tools with proper governance will lead the next generation of infrastructure standards development.
