At the 1853 New York World’s Fair Elisha Otis amazed a crowd when he ordered the only rope holding the platform on which he was standing cut by an axeman. The platform fell only a few inches before coming to a halt; thus proving the safety locking mechanism he had invented will work. These elevators quickly became the type in most common usage and made vertical living possible.
Most large research universities have 100 – 1000 elevators that are highly regulated, maintained by highly regulated service personnel and inspected by highly trained conformance operatives; thus our primary interest in state-specific regulations. We have a secondary interest in innovation in the technology generally. Many sustainability goals urged in academic circles — which include greater population density in smaller areas — are challenged by mobility issues.
From the project prospectus:
“…The main feature of these products is that they are an integral part of industrial, residential or public buildings. Consequently, they should be adaptable to the technical and architectural constraints of such buildings. They must also meet the capacity requirements imposed by the intended use of the building. These products are considered as means of transport and therefore represent an essential component of the functional life of the buildings in which they are installed. Contrary to most public means of transport, they are intended for free use and operation by their passengers, which makes the integration of safety an essential concern…”

Today we break form from our normal custom of assessing conceptual movement in stabilized safety and sustainability standards for education settlements and, instead, venture into a domain that will inform nearly everything we do; and with gathering pace.
We begin with the action among the experts in the organizations listed below:
Overall, the U.S. approach to quantum computing standards is multifaceted, involving federal agencies, industry consortia, academic research, and participation in international standard-setting bodies.
Evensong is a traditional Anglican choral service that takes place in the late afternoon or early evening, typically around sunset. It is also known as Evening Prayer or Vespers.
The service consists of a series of prayers, psalms, canticles, and readings from the Bible, which are sung or chanted by a choir in four-part harmony. The choral music often features elaborate harmonies and complex counterpoint, and is usually accompanied by an organ or other instruments.
Evensong has been an important part of the British choral tradition for centuries, and is still performed in many Anglican churches throughout the UK and beyond. The tradition is particularly strong in Oxford and Cambridge, where the famous college choirs perform regular Evensong services that are open to the public.
The origins of Evensong can be traced back to the monastic offices of the Middle Ages, when monks would gather in the evening to sing the psalms and other prayers. Over time, these services evolved into more elaborate and musically sophisticated forms, which were eventually adopted by the Anglican Church and other Protestant denominations.
Today, Evensong is appreciated for its beauty and spiritual depth, as well as its contribution to the rich heritage of British choral music.

Meeting Notes in red
Loss of electric power and internet service happens more frequently and poses at least an equal — if not greater threat — to public safety. So why does neither the National Electrical Code or the National Electrical Safety Code integrate reliability into their core requirements? Reliability requirements appear in a network of related documents, either referenced, or incorporated by reference; sometimes automatically, sometimes not.
NESC Main Committee Membership: Page xii
Apart from the IEEE as the accredited standards developer, there are no “pure non-government user-interests” on this committee; although ANSI’s Essential Requirements for balance of interests provides highly nuanced interpretation. The Classifications on Page xiii represents due diligence on meeting balance of interest requirements.
In our case, we are one of many large universities that usually own district energy plants that both generate and purchase generate electric power (as sometimes provide var support to utilities when necessary; as during the August 2003 North American outage). For University of Michigan, for example, has about 20 service points at 4.8 – 120 kV. Its Central Power Plant is the largest cogeneration plant on the DTE system.

Absence of internet service is at least as much a hazard, and more frequent, than downed wires. Is there a standards solution? Consideration of interoperability of internet service power supported on utility poles should track in the next revision.
No mention of any reliability related IEEE reliability standards in the present edition. Why is this?

Survivability of communication network signaling
municipal broadband network, digital subscriber line, surveillance cameras
wireless communication system
010. Purpose | PDF Page 40
Looks like improvement since last edition. Suggest explicit Informational Note, as in the NEC, using “reliability” and referring to other agencies. “Abnormal events” could be tighter and refer to other standards for abnormal, steady-state events. The clarification of purpose is welcomed although a great deal remains uncovered by other best practice literature; though that can be repaired in this edition.
Legacy of shared circuit path standards. Should provisions be made for municipal surveillance, traffic and vehicle control infrastructure. What would that look like?
011. Scope | Covered PDF Page 40
3. Utility facilities and functions of utilities that either (a) generate energy by conversion from
some other form of energy such as, but not limited to, fossil fuel, chemical, electrochemical,
nuclear, solar, mechanical, wind or hydraulic or communication signals, or accept energy or
communication signals from another entity, or (b) provide that energy or communication
signals through a delivery point to another entity.
5. Utility facilities and functions on the line side of the service point supplied by underground or
overhead conductors maintained and/or installed under exclusive control of utilities located on
public or private property in accordance with legally established easements or rights-of-way,
contracts, other agreements (written or by conditions of service), or as authorized by a
regulating or controlling body.
NOTE: Agreements to locate utility facilities on property may be required where easements are either
(a) not obtainable (such as locating utility facilities on existing rights-of-way of railroads or other entities,
military bases, federal lands, Native American reservations, lands controlled by a port authority, or other
governmental agency), or (b) not necessary (such as locating facilities necessary for requested service to a
site).
012. General Rules | Covered PDF Page 42
For all particulars not specified, but within the scope of these rules, as stated in Rule 011A, design,
construction, operation, and maintenance should be done in accordance with accepted good practice
for the given local conditions known at the time by those responsible for the communication or
supply lines and equipment
General purpose clause could use some work since no definition of “accepted good practice”. Refer to IEEE bibliography.
Section 2: Definition of special terms | PDF Page 46
Recommendations elsewhere should track here.
The word “installation” appears 256 times and is generally understood in context by experts. Suggest borrow from NEC to clarify our concern for including co-linear/communication circuits.

Safety Rules for the Installation and Maintenance of Overhead Electric Supply and Communication Line | PDF Page 111
Has anyone confirmed that these tables match NEC Table 495.24 lately? If it helps: there were no meaningful changes in the 2023 NEC in Article 495, the high voltage article
Section 11. Protective arrangements in electric supply stations | PDF Page 77
A safety sign shall be displayed on or beside the door or gate at each entrance. For fenced or
walled electric supply stations without roofs, a safety sign shall be displayed on each exterior
side of the fenced or wall enclosure. Where the station is entirely enclosed by walls and roof, a
safety sign is required only at ground level entrances. Where entrance is gained through
sequential doors, the safety sign should be located at the inner door position. (A clarification but no change. See Standards Michigan 2017 proposals)

The word “reliability” appears only three times. Should it track in the NESC or should it track in individual state requirements. So neither the NEC nor the NESC couples closely with power and communication reliability; despite the enormity and speed of research.
