Lightning Protection Systems

“Benjamin Franklin Drawing Electricity from the Sky” 1816 Benjamin West

 

Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.

He used a kite and a key to demonstrate that lightning was a form of electricity.

This experiment marked an important milestone in understanding the nature of electricity

and laid the foundation for the development of lightning rods and other lightning protection systems.

 

Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems

FREE ACCESS

To paraphrase the NFPA 780 prospectus:

  • This document shall cover traditional lightning protection system installation requirements for the following:
       (1) Ordinary structures
       (2) Miscellaneous structures and special occupancies
       (3) Heavy-duty stacks
       (4) Structures containing flammable vapors, flammable gases, or liquids with flammable vapors
       (5) Structures housing explosive materials
       (6) Wind turbines
       (7) Watercraft
       (8) Airfield lighting circuits
       (9) Solar arrays
  • This document shall address lightning protection of the structure but not the equipment or installation requirements for electric generating, transmission, and distribution systems except as given in Chapter 9 and Chapter 12.

(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power.  Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)

  • This document shall not cover lightning protection system installation requirements for early streamer emission systems or charge dissipation systems.

“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height

“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.

Related grounding and bonding  requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code.  This standard does not establish evacuation criteria.  

The current edition is dated 2023 and, from the transcripts, you can observe concern about solar power and early emission streamer technologies tracking through the committee decision making.  Education communities have significant activity in wide-open spaces; hence our attention to technical specifics.

Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard

Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:

Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.

Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.

Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.

Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.

Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.

Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.

Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.

The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance. 

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.

NCAA Guideline: Lightning Safety
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.

Today we break down the literature for building, maintaining and supporting the computing infrastructure of education communities.  We use the term “infotech” gingerly to explain action for a  broad span of technologies that encompass enterprise servers and software, wireless and wired networks, campus phone networks, and desktop computers that provide administrative services and career tech video production.   The private sector has moved at light speed to respond to the circumstances of the pandemic; so have vertical incumbents evolving their business models to seek conformance revenue in this plasma-hot domain.

Starting 2023 we break down the topic accordingly:

Infotech 100: Survey of the principal standards developing organizations whose catalogs are incorporated by reference into federal and state legislation.  Revision cycles.

2024 Update to ASHRAE Position Statements

List of Titles, Scopes and Purposes of the ASHRAE Catalog

Public Review Draft Standards

As of the date of this post, no proposed revisions to the ASHRAE 90.4 have been released for public consultation.  Keep in mind that its normative reference — ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings — is continually under revision; frequently appearing in electrical engineering design guidelines, construction specifications, commissioning and O&M titles in our industry and others.

ASHRAE 90.4 defines an alternate compliance path, specific to data centers, while the compliance requirements for “non-data center” components are contained in ASHRAE 90.1 .  The 90.4 structure also streamlines the ongoing maintenance process as well ensures that Standards 90.1 and 90.4 stay in their respective lanes to avoid any overlap and redundancies relating to the technical and administrative boundaries.  Updates to ASHRAE 90.1 will still include the alternate compliance path defined in ASHRAE 90.4. Conversely the 2022 Edition of 90.4-2022 refers to ASHRAE 90.1-2022; cross-referencing one another synchronously

Originally posted Summer 2020.

 

ASHRAE International has released four new addenda to its energy conservation consensus document ASHRAE 90.4-2016 Energy Standard for Data Centers.  This document establishes the minimum energy efficiency requirements of data centers for design and construction, for the creation of a plan for operation and maintenance and for utilization of on-site or off-site renewable energy resources.

It is a relatively new document more fully explained in an article published by ASHRAE in 2016 (Click here).   The addenda described briefly:

Addendum a  – clarifies existing requirements in Section 6.5 as well as introduce new provisions to encourage heat recovery within data centers.

Addendum b  – clarifies existing requirements in Sections 6 and 11 and to provide guidance for taking credit for renewable energy systems.

Addendum d  – a response to a Request for Interpretation on the 90.4 consideration of DieselRotary UPS Systems (DRUPS) and the corresponding accounting of these systems in the Electrical Loss Component (ELC). In crafting the IC, the committee also identified several marginal changes to 90.4 definitions and passages in Section 8 that would add further clarity to the issue. This addendum contains the proposed changes for that aim as well as other minor changes to correct spelling or text errors, incorporate the latest ELC values into Section 11, and to refresh information in the Normative Reference.

Addendum e adds language to Section 11 intended to clarify how compliance with Standard 90.4 can be achieved through the use of shared systems.

Comments are due September 6th.   Until this deadline you may review the changes and comment upon them by by CLICKING HERE

National Electrical Definitions

NFPA Glossary of Terms

Because electrotechnology changes continually, definitions (vocabulary) in its best practice literature changes continually; not unlike any language on earth that adapts to the moment and place.

The changes reflect changes in technology or changes in how the technology works in practice; even how the manufacturers create adaptations to field conditions by combining functions.   Any smart electrical component has a digital language embedded in it, for example.

Consider the 2023 National Electrical Code.  Apart from many others the NEC will contain a major change to Article 100 (Definitions); the subject of elevated debate over the past three years.

When we refer “language” we must distinguish between formal language, informal language, colloquial language and dialect which may differ the language spoken, language written at the office and language used on the job site.  “Terms of art”

FREE ACCESS: 2020 National Electrical Code (NFPA 70)

2023 NEC Public Input Report CMP-1 (868 pages)

2023 NEC Second Draft Public Comment Report (914 pages)

Are these terms (or, “terms of art”) best understood in context (upstream articles in Chapters 4 through 8) — or should they be adjudicated by the 14 Principals of Code Making Panel 1?   The answer will arrive in the fullness of time.   Many changes to the National Electrical Code require more than one cycle to stabilize.

Code Making Panel 1 has always been the heaviest of all NEC panels.  As explained n our ABOUT, the University of Michigan held a vote in CMP-1 for 20+ years (11 revision cycles) before moving to the healthcare facilities committee for the IEEE Education & Healthcare Facilities Committee.  Standards Michigan continues its involvement on behalf of the US education facility industry — the second largest building construction market.  There is no other pure user-interest voice on any technical committee; although in some cases consulting companies are retained for special purposes.

To serve the purpose of making NFPA 70 more “useable” we respect the Standards Council decision to make this change if it contributes to the viability of the NFPA business model.  We get to say this because no other trade association comes close to having as enduring and as strong a voice:  NFPA stands above all other US-based SDO’s in fairness and consideration of its constituency.  The electrical safety community in the United States is a mighty tough crowd.

If the change does not work, or work well enough, nothing should prohibit reversing the trend toward “re-centralizing” — or “de-centralizing” the definitions.

Public comment on the First Draft of the 2026 Edition will be received until August 28, 2024.

“Landscape between Storms” 1841 Auguste Renoir

 

When is it ever NOT storm season somewhere in the United States; with several hundred schools, colleges and universities in the path of them? Hurricanes also spawn tornadoes. This title sets the standard of care for safety, resilience and recovery when education community structures are used for shelter and recovery.  The most recently published edition of the joint work results of the International Code Council and the ASCE Structural Engineering Institute SEI-7 is linked below:

2020 ICC/NSSA 500 Standard for the Design and Construction of Storm Shelters.

Given the historic tornados in the American Midwest this weekend, its relevance is plain.  From the project prospectus:

The objective of this Standard is to provide technical design and performance criteria that will facilitate and promote the design, construction, and installation of safe, reliable, and economical storm shelters to protect the public. It is intended that this Standard be used by design professionals; storm shelter designers, manufacturers, and constructors; building officials; and emergency management personnel and government officials to ensure that storm shelters provide a consistently high level of protection to the sheltered public.

This project runs roughly in tandem with the ASCE Structural Engineering Institute SEI-17 which has recently updated its content management system and presented challenges to anyone who attempts to find the content where it used to be before the website overhaul.    In the intervening time, we direct stakeholders to the link to actual text (above) and remind education facility managers and their architectural/engineering consultants that the ICC Code Development process is open to everyone.

Critical Operations Power Systems


The original University of Michigan codes and standards enterprise advocated actively in Article 708 Critical Operations Power Systems (COPS) of the National Electrical Code (NEC) because of the elevated likelihood that the education facility industry managed assets that were likely candidates for designation critical operations areas by emergency management authorities.

Because the NEC is incorporated by reference into most state and local electrical safety laws, it saw the possibility that some colleges and universities — particularly large research universities with independent power plants, telecommunications systems and large hospitals  — would be on the receiving end of an unfunded mandate.   Many education facilities are identified by the Federal Emergency Management Association as community storm shelters, for example.

As managers of publicly owned assets, University of Michigan Plant Operations had no objection to rising to the challenge of using publicly owned education facilities for emergency preparedness and disaster recovery operations; only that meeting the power system reliability requirements to the emergency management command centers would likely cost more than anyone imagined — especially at the University Hospital and the Public Safety Department facilities.  Budgets would have to be prepared to make critical operations power systems (COPS) resistant to fire and flood damages; for example.

Collaboration with the Institute of Electrical and Electronic Engineers Industrial Applications Society began shortly after the release of the 2007 NEC.  Engineering studies were undertaken, papers were published (see links below) and the inspiration for the IEEE Education & Healthcare Facilities Committee developed to provide a gathering place for power, telecommunication and energy professionals to discover and promulgate leading practice.   That committee is now formally a part of IEEE and collaborates with IAS/PES JTCC assigned the task of harmonizing NFPA and IEEE electrical safety and sustainability consensus documents (codes, standards, guidelines and recommended practices.

The transcript of NEC Code Making Panel 13 — the committee that revises COPS Article 708 every three years — is linked below:

NEC CMP-13 First Draft Balloting

NEC CMP-13 Second Draft Balloting

The 2023 Edition of the National Electrical Code does not contain revisions that affect #TotalCostofOwnership — only refinement of wiring installation practices when COPS are built integral to an existing building that will likely raise cost.  There are several dissenting comments to this effect and they all dissent because of cost.   Familiar battles over overcurrent coordination persist.

Our papers and proposals regarding Article 708 track a concern for power system reliability — and the lack of power  — as an inherent safety hazard.   These proposals are routinely rejected by incumbent stakeholders on NEC technical panels who do not agree that lack of power is a safety hazard.  Even if lack of power is not a safety hazard, reliability requirements do not belong in an electrical wiring installation code developed largely by electricians and fire safety inspectors.  The IEEE Education & Healthcare Facilities Committee (IEEE E&H) maintains a database on campus power outages; similar to the database used by the IEEE 1366 committees that develop reliability indices to enlighten public utility reliability regulations.

Public input on the 2026 revision to the NEC will be received until September 7th.  We have reserved a workspace for our priorities in the link below:

Hospital Plug Load

Today at 16:00 UTC we examine relatively recent transactions in electrotechnologies — power, information and communication technology — that are present (and usually required) in patient care settings.   At a patient’s bedside in a hospital or healthcare setting, various electrical loads or devices may be present to provide medical care, monitoring, and comfort. Some of the common electrical loads found at a patient’s bedside include:

Hospital Bed: Electric hospital beds allow for adjustments in height, head position, and leg position to provide patient comfort and facilitate medical procedures.

Patient Monitor: These monitors display vital signs such as heart rate, blood pressure, oxygen saturation, and respiratory rate, helping healthcare professionals keep track of the patient’s condition.

Infusion Pumps: These devices administer medications, fluids, and nutrients intravenously at a controlled rate.

Ventilators: Mechanical ventilators provide respiratory support to patients who have difficulty breathing on their own.

Pulse Oximeter: This non-invasive device measures the oxygen saturation level in the patient’s blood.

Electrocardiogram (ECG/EKG) Machine: It records the electrical activity of the heart and is used to diagnose cardiac conditions.

Enteral Feeding Pump: Used to deliver liquid nutrition to patients who cannot take food by mouth.

Suction Machine: It assists in removing secretions from the patient’s airway.

IV Poles: To hold and support intravenous fluid bags and tubing.

Warming Devices: Devices like warming blankets or warm air blowers are used to maintain the patient’s body temperature during surgery or recovery.

Patient Call Button: A simple push-button that allows patients to call for assistance from the nursing staff.

Overbed Tables: A movable table that allows patients to eat, read, or use personal items comfortably.

Reading Lights: Bedside lights that allow patients to read or perform tasks without disturbing others.

Television and Entertainment Devices: To provide entertainment and alleviate boredom during the patient’s stay.

Charging Outlets: Electrical outlets to charge personal electronic devices like smartphones, tablets, and laptops.

It’s important to note that the specific devices and equipment present at a patient’s bedside may vary depending on the level of care required and the hospital’s equipment standards. Additionally, strict safety measures and electrical grounding are essential to ensure patient safety when using electrical devices in a healthcare setting.  

We have been tracking the back-and-forth on proposals, considerations, adoption and rejections in the 3-year revision cycles of the 2023 National Electrical Code and the2021 Healthcare Facilities Code.  We will use the documents linked below as a starting point for discussion; and possible action:

Children’s Hospital Neonatal Intensive Care

Some of the common electro-technologies used in a neonatal care unit include:

  • Incubators: These temperature-controlled units create a controlled environment to keep premature or sick infants warm and protected.
  • Ventilators: Mechanical ventilators assist newborns with respiratory distress by delivering oxygen and helping them breathe.
  • Monitors: These devices track vital signs such as heart rate, oxygen levels, blood pressure, and temperature to ensure the baby’s health and detect any abnormalities.
  • Phototherapy Lights: Special lights are used to treat jaundice in newborns, helping to break down excess bilirubin in the blood.
  • Intravenous (IV) Pumps: These pumps are used to deliver medications, fluids, and nutrients directly into the baby’s bloodstream.
  • Feeding Tubes: For infants who are unable to feed orally, feeding tubes are used to deliver breast milk or formula directly into their stomach.
  • Blood Gas Analyzers: These machines measure the levels of oxygen, carbon dioxide, and other gases in a baby’s blood to monitor respiratory status and acid-base balance.
  • Infusion Pumps: Used to administer controlled amounts of fluids, medications, or nutrients to newborns.
  • CPAP/BiPAP Machines: Continuous Positive Airway Pressure (CPAP) and Bi-level Positive Airway Pressure (BiPAP) machines help newborns with breathing difficulties by providing a continuous flow of air pressure.
  • Neonatal Resuscitation Equipment: This includes equipment such as resuscitation bags, endotracheal tubes, laryngoscopes, and suction devices used during emergency situations to assist with newborn resuscitation.

It’s important to note that specific tools and equipment may vary depending on the level of neonatal care provided by the unit, the needs of the infants, and the policies of the healthcare facility.

Neonatal care, as a specialized field, has been shaped by the contributions of several pioneers in medicine. Here are a few notable figures who have made significant advancements in neonatal care:

  • Dr. Virginia Apgar was an American obstetrical anesthesiologist who developed the Apgar score in 1952. The Apgar score is a quick assessment tool used to evaluate the overall health of newborns immediately after birth. It assesses the baby’s heart rate, respiratory effort, muscle tone, reflex irritability, and color, providing valuable information for prompt intervention and monitoring.
  • Dr. Martin Couney, a pioneering physician, established incubator exhibits at world fairs and amusement parks in the early 20th century. He promoted the use of incubators to care for premature infants and played a significant role in popularizing the concept of neonatal intensive care.
  • Dr. Virginia A. Apgar, an American pediatrician and neonatologist, made significant contributions to the field of neonatology. She specialized in the care of premature infants and conducted extensive research on neonatal resuscitation and newborn health. She also developed the Apgar scoring system, although unrelated to Dr. Virginia Apgar mentioned earlier.
  • Dr. Lula O. Lubchenco was an influential researcher and neonatologist who made important contributions to the understanding of newborn growth and development. She developed the Lubchenco Growth Chart, which provides a standardized assessment of a newborn’s size and gestational age, aiding in the identification and monitoring of growth abnormalities.
  • Dr. Mary Ellen Avery was a renowned American pediatrician and researcher whose work focused on understanding and treating respiratory distress syndrome (RDS) in premature infants. She identified the importance of surfactant deficiency in RDS and contributed to the development of surfactant replacement therapy, revolutionizing the care of preterm infants.

These individuals, among many others, have played pivotal roles in advancing the field of neonatal care, improving the understanding, diagnosis, treatment, and overall outcomes for newborn infants.
