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.

Electric vehicle charging stations are addressed in the 2024 International Energy Conservation Code (IECC) within two specific appendices:

Appendix RE: This appendix provides detailed requirements for electric vehicle charging infrastructure, focusing on both residential and commercial buildings. It includes definitions and infrastructure standards to ensure that new constructions are equipped to support electric vehicle charging​

Appendix CG: This appendix offers guidance on electric vehicle power transfer and charging infrastructure, emphasizing the integration of EV-ready requirements into building designs. It outlines the necessary provisions for installing and managing EV charging stations, ensuring compliance with energy conservation standards​

.These appendices are part of the broader efforts to incorporate EV infrastructure into building codes, promoting energy efficiency and supporting the transition to electric vehicles.

Keep in mind that many electric vehicle safety and sustainability concepts will track in other titles in the ICC catalog.   It is enlightening to see other energy related proposals tracking in the most recent Group A code revision cycle

The following proposals discussed during the Group A Hearings ended earlier this month are noteworthy:

IBC § 202 (NEW) | G66-21 |  Electrical mobility definitions

IBC § 1107.2, et al | E124-21 & E125-21 & E126-21 |  Electrical vehicle charging stations for R-2 occupancies.

From the Group B revision cycle — COMPLETE MONOGRAPH:

R309.6 Electric vehicle charging stations and systems. Where provided, electric vehicle charging systems shall be installed in accordance with NFPA 70. Electric vehicle charging system equipment shall be listed and labeled in accordance with UL 2202. Electric vehicle supply equipment shall be listed and labeled in accordance with UL 2594.

IBC 406.2.7 Electric vehicle charging stations and systems. Where provided, electric vehicle charging systems shall be installed in accordance with NFPA 70. Electric vehicle charging system equipment shall be listed and labeled in accordance with UL 2202. Electric vehicle supply equipment shall be listed and labeled in accordance with UL 2594. Accessibility to electric vehicle charging stations shall be provided in accordance with Section 1108.

Incumbents are socking in EV concepts all across the ICC catalog.  We refer them to experts in the Industrial Applications Society IEEE E&H Committee.

 

 

One of the more spirited debates in recent revision cycles is the following:

Who shall pay for electrical vehicle charging infrastructure?   

The underlying assumption is that the electrification of the global transportation grid has a net benefit.   We remain mute on that question; the question of net gain.

Of course, many proposals pointed the finger at the stakeholder with the deepest pockets.  Accordingly, new commercial building owners will be required to install charging stations for new buildings.   During 2018 and 2019 we tracked the action in the workspace below so that we could collaborate with the IEEE Education & Healthcare Facilities Committee:

2021 Electric Vehicle Infrastructure

Given that most higher education facilities are classified as commercial, the cost of charging stations will be conveyed into the new building construction budget unless the unit takes an exception.   Generally speaking, most colleges and universities like to display their electric vehicle credentials, even if the use of such charging stations remains sparse.

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.

Yaupon Drink: A Medicine Bundle in the Atlantic World

Steven P. Carriger Jr, University of Tennessee, Knoxville

Abstract. This dissertation examines yaupon drink, a tea made from yaupon holly along with other ingredients, as a medicine bundle in the Atlantic World. Originally a medicinal drink used by Native Americans across the what is today the American South, over time the tea became a trade good demanded by the Spanish and a medicinal herb sought by European botanists and medical practitioners. Chapter One traces yaupon’s origins across the southeast and bundles the drink into the many cosmic and social connections it held. Chapter Two shows how the Spanish colonial presence offered an alternative to yaupon in Florida, through Christianity and its Sacraments even as the Spanish themselves began to commodify it, demanding it as an item of tribute. Chapter Three looks beyond Spanish Florida into the interior of the southeast as Creek, Cherokee, and Natchez towns negotiated the “Shatter Zone” and shows how towns of the Native Americans preserved or changed how they used yaupon in response to European colonialism. Chapter Four explains how the yaupon became a part of medicine and gardens in early modern Europe and how its leaves negotiated the changes that the Enlightenment brought. Using archaeology and European narrative histories, this dissertation examines yaupon drink within its relational fields, recognizing its affordances and how these help write a small piece of a decolonized history of the tangled relationships among Native Americans and Europeans in Southeast and the larger Atlantic World.

“Electrical Building World’s Columbian Exposition Chicago 1892

Today we feature the catalog of the Illumination Engineering Society — one of the first names in standards-setting in illumination technology, globally* with particular interest in its leading title IES LP-1 | LIGHT + DESIGN Lighting Practice: Designing Quality Lighting for People and Buildings.

From its prospectus:

“…LIGHT + DESIGN was developed to introduce architects, lighting designers, design engineers, interior designers, and other lighting professionals to the principles of quality lighting design. These principles; related to visual performance, energy, and economics; and aesthetics; can be applied to a wide range of interior and exterior spaces to aid designers in providing high-quality lighting to their projects.

Stakeholders: Architects, interior designers, lighting practitioners, building owners/operators, engineers, the general public, luminaire manufacturers.  This standard focuses on design principles and defines key technical terms and includes technical background to aid understanding for the designer as well as the client about the quality of the lighted environment. 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:

IES Standards Open for Public Review

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.   Use the login credentials at the upper right of our home page to join us.
