Critical Operations Power Systems

Disaster 500


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.

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:

We find a fair amount of administrative and harmonization action; fairly common in any revision cycle.   We have taken an interest in a few specific concepts that track in academic research construction industry literature:

  • Correlation with Underwriters Laboratory product standards
  • Bi-Directional Charging & Demand Response
  • Connection to interactive power sources

As a wiring safety installation code — with a large installer and inspection constituency — the NEC is usually the starting point for designing the power chain to electric vehicles.   There is close coupling between the NEC and product conformance organizations identified by NIST as Nationally Recognized Testing Laboratories; the subject of a separate post.

After the First Draft is released June 28th public comment is receivable until August 19th.

We typically do not duplicate the work of the 10’s of thousands of National Electrical Code instructors who will be fanning out across the nation to host training sessions for electrical professionals whose license requires mandatory continuing education.  That space has been a crowded space for decades.   Instead we co-host “transcript reading” sessions with the IEEE Education & Healthcare Facilities Committee to sort through specifics of the 2020 NEC and to develop some of the ideas that ran through 2020 proposals but did not make it to final ballot and which we are likely to see on the docket of the 2023 NEC revision.   That committee meets online 4 times monthly.  We also include Article 625 on the standing agenda of our Mobility colloquium; open to everyone.   See our CALENDAR for the next online meeting

Code for Fireworks Display

“Fireworks over Castel Sant’Angelo in Rome” | Jacob Philipp Hackert (1775)

At least twice a year, and during performances with flame effects, public safety departments in colleges and universities have an elevated concern about campus citizen safety, and the safety of the host community, when fireworks are used for celebration.  We find very rigorous prohibitions against the use of fireworks, weapons and explosives on campus.  Education and enforcement usually falls on facility and operation campus safety units.

That much said, we follow development, but do not advocate in NFPA 1123 Code for Fireworks Display, because it lies among a grouping of titles that set the standard of care for many college and university public safety departments that sometimes need to craft prohibitions with consideration for the business purposes of entertainment and celebration in education facilities.   NFPA 1123 is not a long document — only 22 pages of core text — but it contains a few basic considerations for display site selection, clearances and permitting that campus public safety departments will coordinate with the host community.  It references NFPA 1126, Standard for the Use of Pyrotechnics Before a Proximate Audience and NFPA 160 Standard for the Use of Flame Effects Before an Audience.

Something to keep an eye on.  The home page for this code is linked below:

Voice Communications Devices for Use by Emergency Services

The frequency differences between public safety radio and public broadcasting radio are mainly due to their distinct purposes and requirements.

  • Public safety radio operates on VHF and UHF bands for emergency services communication These radio systems are designed for robustness, reliability, and coverage over a specific geographic area. They prioritize clarity and reliability of communication over long distances and in challenging environments. Encryption may also be employed for secure communication.
  • Public broadcasting radio operates on FM and AM bands for disseminating news, entertainment, and cultural content to the general public.  These radio stations focus on providing a wide range of content, including news, talk shows, music, and cultural programming. They often cover broad geographic areas and aim for high-quality audio transmission for listener enjoyment. Unlike public safety radio, public broadcasting radio stations typically do not require encryption and prioritize accessibility to the general public.

Standard on Fire and Emergency Service Use of Thermal Imagers, Two-Way Portable RF Voice Communication Devices, Ground Ladders, and Fire Hose, and Fire Hose Appliances

NFPA 1930 is in a custom cycle due to the Emergency Response and Responder Safety Document Consolidation Plan (consolidation plan) as approved by the NFPA Standards Council.  As part of the consolidation plan, NFPA 1930 is combining Standards NFPA 1801, NFPA 1802, NFPA 1932, NFPA 1937, and NFPA 1962.

Firefighter radio communication faces several special technical challenges due to the nature of the environment they operate in and the criticality of their tasks. Here are some of the key challenges:

  1. Interference and Signal Degradation: Buildings, debris, and firefighting equipment can obstruct radio signals, leading to interference and degradation of communication quality.
  2. Multipath Propagation: Radio signals can bounce off surfaces within buildings, causing multipath propagation, which results in signal fading and distortion.
  3. Limited Bandwidth: Firefighter radio systems often operate on limited bandwidths, which can restrict the amount of data that can be transmitted simultaneously, impacting the clarity and reliability of communication.
  4. Noise: The high noise levels present in firefighting environments, including sirens, machinery, and fire itself, can interfere with radio communication, making it difficult for firefighters to hear and understand each other.
  5. Line-of-Sight Limitations: Radio signals typically require a clear line of sight between the transmitter and receiver. However, in complex urban environments or within buildings, obstructions such as walls and floors can obstruct the line of sight, affecting signal strength and reliability.
  6. Equipment Durability: Firefighter radio equipment needs to withstand harsh environmental conditions, including high temperatures, smoke, water, and physical impacts. Ensuring the durability and reliability of equipment in such conditions is a significant challenge.
  7. Battery Life: Prolonged operations in emergency situations can drain radio batteries quickly. Firefighters need reliable battery life to ensure continuous communication throughout their mission.
  8. Interoperability: Different emergency response agencies may use different radio systems and frequencies, leading to interoperability issues. Ensuring seamless communication between various agencies involved in firefighting operations is crucial for effective coordination and response.
  9. Priority Access: During large-scale emergencies, such as natural disasters or terrorist attacks, communication networks may become congested, limiting access for emergency responders. Firefighters need priority access to communication networks to ensure they can effectively coordinate their efforts.
  10. Training and Familiarity: Operating radio equipment effectively under stress requires training and familiarity. Firefighters must be trained to use radio equipment efficiently and effectively, even in challenging conditions, to ensure clear and concise communication during emergencies.

We are guided by four interdependent titles that set the standard of care for safety and sustainability of occupancies supporting the fine arts in education communities.

(1)  Chapter 43: Spraying, Dipping and Coating Using Flammable or Combustible Material of NFPA 1: Fire Code.   As a “code” the public has free access to the current 2021 Edition , and Chapter 43 at the link below:

NFPA 1 Fire Code / Chapter 43 Spraying, Dipping and Coating Using Flammable or Combustible Materials

You get a sense of the back-and-forth among the technical committee members from the transcripts of committee activity linked below:

First Revisions Report (282 pages)

Our interest lies in fire safety provisions for educational occupancies with activity involving paint, chemicals used with paint (art studios) and Class III combustible materials (garment design & prototyping).

(2) NFPA also has another title — NFPA 33 Standard for Spray Application Using Flammable or Combustible Materials — provides more detail for instructional and facility maintenance operations activity.

(3) NFPA 101 Life Safety Code, much of which is derived from NFPA 1 (See: “How the Fire Code and Life Safety Code Work Together“)

(4) Finally, the International Code Council develops a competitor title — 2021 International Fire Code — which also provides fire safety standards for art, design and fashion studio safety.  The IFC is developed in the Group A tranche of titles:

2021/2022 Code Development Group A

2024/2025/2026 ICC CODE DEVELOPMENT SCHEDULE

We encourage direct participation by education industry user-interests in the ICC and the NFPA code development process.  A user interest in education community would have a job title similar to the following: Principal, Dean, President, Chief of Business Operations, Facility Manager, Trade Shop Foreman.

Elevators rely on electricity to function, and when there’s a power outage, the main source of power is disrupted. Modern elevators often have backup power systems, such as generators or battery packs, to lower the cab to the nearest floor and open the doors, but these systems may not work optimally, or be connected to all elevators or may not exist in older or less well-maintained buildings.

Today we start with getting the source of power right; leaving complicating factors such as alarms, reset and restart sequences.   NFPA 110 is the parent standard which references NFPA 70.

Hospital Plug Load

Today 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:
