Kitchen Wiring

“Le Coin de Cuisine” | 1883 Edwin Deakin

Education communities are stewards of hundreds of commercial-class kitchens in which the proximate risk of electrical energy must be managed — water spills and grease, fires, worn electrical cords on countertop equipment, faulty wiring or equipment, damaged outlets or connectors, and improperly used or damaged extension cords among them.   The safety and sustainability rules for this occupancy class is identified as Assembly Group A-2 in Section 303 of the International Building Code

We explore recent transcripts of expert committee activity in NEC Article 210 and provide links to video commentary.

Public comment on the Second Draft of the 2026 NEC will be received until April 18.  We typically coordinate our effort with the IEEE Education & Healthcare Facilities Committee.  The workspace set up for generating proposals can be found in the link below.

We break down our coverage of laboratory safety and sustainability standards thus:

Laboratories 100 covers a broad overview of the safety and sustainability standards setting catalogs; emphasis on titles incorporated by reference into public safety laws.

Laboratories 200 covers laboratory occupancies primarily for teaching

Laboratories 300 covers laboratories in healthcare clinical delivery.

Laboratories 400 covers laboratories for scientific research; long since creating the field of environmental health and safety in higher education and a language (and acronyms of its own: CSHEMA)

In the most recent fiscal year, the National Institutes of Health had a budget of approximately $47.7 billion. A substantial portion of this budget is allocated to research at colleges and universities. Specifically, about 83% of NIH’s funding, which translates to roughly $39.6 billion, is awarded for extramural research. This funding is distributed through nearly 50,000 competitive grants to more than 2,500 universities, medical schools, and other research institutions across the United States​

The cost to build a “standard” classroom runs about $150 to $400 per square foot; a scientific research laboratory about $400 to $1200 per square foot.

Laboratories 500 is broken out as a separate but related topic and will cover conformity and case studies that resulted in litigation.  Both Laboratories 200 and 400 will refer to the cases but not given a separate colloquium unless needed.

Research findings related to laboratory safety:

  1. Identifying and Evaluation Hazards in Research Laboratories
  2. “Evaluating the Efficacy of Laboratory Hazard Assessment Tools for Risk Management in Academic Research Laboratories” – This study from 2021 evaluated the effectiveness of various laboratory hazard assessment tools in academic research laboratories, and found that a combination of tools and approaches may be most effective for managing risks.
  3. “A Framework for Assessing Laboratory Safety Culture in Academic Research Institutions” – This 2020 study developed a framework for assessing laboratory safety culture in academic research institutions, which can help identify areas for improvement and promote a culture of safety.
  4. “Enhancing Laboratory Safety Culture Through Peer-to-Peer Feedback and Coaching” – This 2020 study found that peer-to-peer feedback and coaching can be an effective way to enhance laboratory safety culture, as it encourages open communication and feedback among colleagues.
  5. “Assessing the Effectiveness of Laboratory Safety Training Programs for Graduate Students” – This 2019 study evaluated the effectiveness of laboratory safety training programs for graduate students, and found that interactive and hands-on training was more effective than traditional lecture-based training.
  6. “Improving Laboratory Safety Through the Use of Safety Climate Surveys” – This 2018 study found that safety climate surveys can be an effective way to improve laboratory safety, as they provide insight into employee perceptions of safety culture and identify areas for improvement.
  7. Chemistry laboratory safety climate survey (CLASS): A tool for measuring students’ perceptions of safety

These recent research findings suggest that laboratory safety culture can be improved through a variety of approaches, including hazard assessment tools, peer-to-peer feedback and coaching, interactive training, and safety climate surveys.  Some of these findings will likely set the standard of care we will see in safety standards incorporated by reference into public safety regulations.

Today we break down action in the literature governing the safety and sustainability of instruction and research laboratories in the United States specifically; but also with sensitivity to similar enterprises in research universities elsewhere in the world.  “Everyone” has an iron in this fire:

International Building Code Chapter 38: Higher Education Laboratories

ASCE Structural Engineering Institute (so that the foundations and “bone structure” of laboratories survive earthquakes, floods and other Force majeure mayhem)

National Electrical Code Chapter 5: Special Occupancies

ASHRAE Laboratory Design Guide

NFPA 45  Standard on Fire Protection for Laboratories Using Chemicals

IEEE Electrical Safety in Academic Laboratories

…and ISEA, AWWA, AIHA, BIFMA, CLSI, LIA, IAPMO, NSF, UL etc. among ANSI accredited standards developing organizations…

..and addition to NIST, Federal code of Regulations Title 29, NIH, CDC, FEMA, OSHA etc

…and state level public health regulations; some of them adapted from OSHA safety plans

Classroom and offices are far simpler.  Laboratories are technically complicated and sensitive area of concern for education communities not only responsible for the safety of instructional laboratories but also global communities with faculty and staff that must simultaneously collaborate and compete.  We have been tip-toeing through the technical and political minefields for nearly 20 years now and have had some modest success that contributes to higher safety and lower costs for the US education community.

Ice Hockey Arena Lighting

National Collegiate Athletic Association: August 2022 IRS Form 900 Tax Filing

"People don’t notice whether it’s winter or summer when they’re happy" -- Anton Chekhov

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 hockey season the document linked below provides information to illumination designers and facility managers:

Code ignis MMXXIV: Fire Lanes & Parking

NFPA 1 Chapter 18 – Fire Department Access and Water Supply
Public Input on the 2027 Edition closes June 4, 2025

Extinguishing A fire at the Equitable Building skyscraper in New York City, January 1912.

The parent title in the NFPA catalog — NFPA 1 — sets standards for fire lanes by addressing them within various chapters and sections; depending on the specific aspects of fire protection, access, and safety they pertain to. Here are some of the key sections and chapters in NFPA 1 that may include relevant information regarding fire lanes:

  1. Chapter 18: New High-Rise Buildings: This chapter may include requirements related to access for firefighting operations, which could encompass provisions for fire lanes.
  2. Chapter 20: New Educational and Day-Care Occupancies: Requirements related to access for emergency responders in educational facilities, including provisions for fire lanes, may be addressed in this chapter.
  3. Chapter 22: Existing Educational and Day-Care Occupancies: Similar to Chapter 20, this chapter may contain provisions for existing educational facilities regarding fire protection and access.
  4. Chapter 24: New Residential Board and Care Occupancies: Requirements for access and fire protection in residential board and care occupancies, including provisions for fire lanes, may be found in this chapter.
  5. Chapter 30: New Mercantile Occupancies: This chapter may include provisions related to access and fire protection in mercantile occupancies, which could involve requirements for fire lanes.
  6. Chapter 32: Existing Mercantile Occupancies: Similar to Chapter 30, this chapter may address requirements for existing mercantile occupancies, including provisions for fire lanes.

Since NFPA 1 covers a wide range of fire safety topics, including building design, fire protection systems, and emergency procedures, specific requirements related to fire lanes may be distributed throughout the document rather than consolidated in a single section. It’s important to carefully review the relevant chapters and sections of NFPA 1 to ensure compliance with applicable requirements for fire lane design, construction, and maintenance.

Best practice for determining snow zones, as the criteria for designating these zones can vary depending on factors such as geography, climate, population density, infrastructure, and available resources. However, municipalities typically develop their own criteria and guidelines based on these factors to create effective snow removal plans.

Common principles and factors that many municipalities consider when determining snow zones, as mentioned in the previous response. These include weather patterns, topography, traffic volume and patterns, residential density, critical infrastructure, public safety considerations, and feedback from residents and stakeholders.

Some municipalities may also adopt best practices and recommendations from organizations such as the American Public Works Association (APWA) or the National Association of City Transportation Officials (NACTO) to inform their snow removal planning processes. These organizations may offer guidance on snow zone designations, prioritization of routes, and effective snow removal techniques based on industry standards and research.

Ultimately snow zones respond to the specific needs and characteristics of each municipality, with the goal of efficiently managing winter weather events to ensure public safety and mobility.

Stochastic hybrid models for predicting the behavior of drivers facing the yellow-light-dilemma

Paul A. Green | University of Michigan

 Daniel Hoehener & Domitilla Del Vecchio | Massachusetts Institute of Technology

  

Abstract:  We address the problem of predicting whether a driver facing the yellow-light-dilemma will cross the intersection with the red light. Based on driving simulator data, we propose a stochastic hybrid system model for driver behavior. Using this model combined with Gaussian process estimation and Monte Carlo simulations, we obtain an upper bound for the probability of crossing with the red light. This upper bound has a prescribed confidence level and can be calculated quickly on-line in a recursive fashion as more data become available. Calculating also a lower bound we can show that the upper bound is on average less than 3% higher than the true probability. Moreover, tests on driving simulator data show that 99% of the actual red light violations, are predicted to cross on red with probability greater than 0.95 while less than 5% of the compliant trajectories are predicted to have an equally high probability of crossing. Determining the probability of crossing with the red light will be important for the development of warning systems that prevent red light violations.

The home is the empire! There is no peace more delightful than one's own fireplace. - Marcus Tullius Cicero

"Firelight magnifies the soul of a room, and it is there that life unfolds in its purest form" -- Thomas HardyRobert Frost: "Some say the world will end in fire, some say in ice."

An inglenook is an intimate space typically found beside a fireplace. Inglenooks often have built-in seating or benches, providing a comfortable spot for people to gather around the warmth of the fire.  Originally inspired by cooking, but over time, they became more functional as spaces for relaxation, reflection, reading and socializing.

Campus Micromobility

Artist: Syd Mead | Photo Credit: United States Steel

We find town-gown political functionaries working to accommodate students traveling on micro-scooters.  Several non-profit trade associations compete for “ownership” of some part of the economic activity associated with micromobility.   One of several domain incumbents is SAE International.   Here is how SAE International describes the micromobility transformation:

“…Emerging and innovative personal mobility devices, sometimes referred to as micromobility, are proliferating in cities around the world. These technologies have the potential to expand mobility options for a variety of people. Some of these technologies fall outside traditional definitions, standards, and regulations. This committee will initially focus on low-speed micromobility devices and the technology and systems that support them that are not normally subject to the United States Federal Motor Vehicle Safety Standards or similar regulations. These may be device-propelled or have propulsion assistance. They are low-speed devices that have a maximum device-propelled speed of 30 mph. They are personal transportation vehicles designed to transport three or fewer people. They are consumer products but may be owned by shared- or rental-fleet operators. This committee is concerned with the eventual utilization and operational characteristics of these devices, and how they may be safely incorporated in the transportation infrastructure. This committee will develop and maintain SAE Standards, Recommended Practices, and Information Reports within this classification of mobility. The first task of the committee will be to develop a taxonomy of low-speed micromobility devices and technologies. Currently, many of these terms are not consistently named, defined, or used in literature and practice. This task will also help refine the scope of the committee and highlight future work….”

Micromobility standards development requires sensitivity to political developments in nearly every dimension we can imagine.

University of Toledo

Specifically, we follow developments in SAE J3194: Taxonomy and Definitions for Terms Related to Micromobility Devices.  Getting scope, title, purpose and definitions established is usually the first step in the process of developing a new technical consensus product.   From the project prospectus:

This Recommended Practice provides a taxonomy and definitions for terms related to micromobility devices. The technical report covers low-speed micromobility devices (with a maximum device-propelled speed of 30 mph) and the technology and systems that support them that are not normally subject to the United States Federal Motor Vehicle Safety Standards or similar regulations. These devices may be device-propelled or have propulsion assistance. Micromobility devices are personal transportation vehicles designed to transport three or fewer people. They are consumer products but may be owned by shared- or rental-fleet operators. This Recommended Practice does not provide specifications or otherwise impose requirements of micromobility devices.

Apart from the rising level of discussion on vehicle-to-grid technologies (which we track more closely with the IEEE Education & Healthcare Facilities Committee) there is no product at the moment that business units in the education industry can comment upon.   Many relevant SAE titles remain “Works in Progress”.  When a public commenting opportunity on a candidate standard presents itself we will post it here.

We host periodic Mobility colloquia; SAE titles standing items on the agenda.  See our CALENDAR for the next online session; open to everyone.
