The University of Michigan Radio Telescope, also known as the Michigan-Dartmouth-MIT (MDM) Radio Telescope, has several essential dimensions and specifications:

Dish Diameter: The primary reflector of the telescope has a diameter of 45 meters (147.6 feet). This large size allows it to collect radio waves effectively.

Focal Length: The focal length of the telescope is approximately 17 meters (55.8 feet). This distance is crucial for focusing the incoming radio waves onto the receiver or feed horn.

Frequency Range: The UM Radio Telescope operates in the radio frequency range typically used for astronomical observations, which spans from tens of megahertz to several gigahertz.

Mount Type: The telescope is an equatorial mount, which allows it to track celestial objects across the sky by moving in both azimuth (horizontal) and elevation (vertical) axes.

Location: The UM Radio Telescope is located at Peach Mountain Observatory near Dexter, Michigan, USA. Its geographical coordinates are approximately 42.39°N latitude and 83.96°W longitude.

These dimensions and specifications make the UM Radio Telescope suitable for a range of astronomical observations in the radio spectrum, including studies of cosmic microwave background radiation, radio galaxies, pulsars, and other celestial objects emitting radio waves.

Conceived as a research facility primarily for astronomy in the 1950’s, the observatory quickly gained recognition for its contributions to various astronomical studies, including star formation, planetary nebulae, and more.

“Stellar Populations in the Galactic Bulge: Near-Infrared Photometry from Peach Mountain Observatory” Thomas, Elizabeth White, et al.

“Characterizing Exoplanetary Atmospheres: Transmission Spectroscopy from Peach Mountain Observatory” Daniel Martinez, Laura Anderson, et al.

Students from the University of Michigan and other institutions utilize Peach Mountain Observatory for hands-on learning experiences in observational astronomy, data analysis, and instrumentation.

Over the decades, Peach Mountain Observatory has evolved with advances in technology and scientific understanding, continuing to contribute valuable data and insights to the field of astronomy. Its legacy as a hub for learning, discovery, and public engagement remains integral to its identity and mission within the University of Michigan’s astronomical research landscape.

Today we run through recent action in fire safety best practice literature.  Even though fire safety technologies comprise about 2-4 percent of a new building budget, the influence of the fire safety culture dominates all aspects campus safety; cybersecurity of public safety communication technology for example.

A small sample of the issues we have tracked in the past: (2002-2023).  Items in RED indicate success in reducing cost with no reduction in safety (i.e. successful rebuttal, typically market-making by incumbents)

  • Limiting vendor lock-in (promote interoperability) in building additions.
  • Limiting the tendency to lowball first cost in order to achieve vendor lock-in later in the facility life-cycle
  • Dormitory kitchen fire safety

Fire Safety of University Dormitory Based on Bayesian Network

  • Clarification of mixed-occupancy classifications (occupant loading)
  • Fixed interval (rather than risk-informed) inspection, testing and maintenance of fire alarm and protection system components
  • Fire alarm system upgrades during renovation

Gamification Teaching in School Fire Safety

  • Mixed zone and addressable alarm system wiring
  • Wireless initiation devices
  • Integrated fire protection systems (NFPA 3&4)
  • Portable fire extinguishers (NFPA 10)

Hospital Evacuation under Fire

  • Alarm system re-set procedures
  • Sprinkler system coverage for animals in research
  • Scalability of fire safety professional certification
  • Sprinklering of off-campus student housing
  • Advocating central (or campus district) fire pump systems

One of the newer issues to revisit over the past few years is the fire safety of tents.   Many colleges and universities are setting up large commercial tents outside buildings (within range of Wi-Fi) for students to congregate, study and dine.  We are also seeing back and forth on fire safety in theatrical performance venues in the International Code Council building safety catalog.

We approach these titles with an eye toward driving risk-informed, performance requirements that reduce risk and cost for the user interest; while recognizing the responsibility of competitor stakeholders.   It is not a friendly space for the user-interest who seeks to optimally resolve the competing requirements of safety and economy.   Vertical incumbents completely dominate this domain.

“Creation of humanity by Prometheus as Athena looks on”

Fire safety leadership usually finds itself involved in nearly every dimension of risk on the #WiseCampus; not just the built environment but security of interior spaces with combustibles but along the perimeter and within the footprint of the education community overall.

The Campus Fire Marshal, for example, usually signs the certificate of occupancy for a new building but may be drawn into meetings where decisions about cybersecurity are made.   Fire protection systems coincide with evacuation systems when there is no risk and both may be at risk because of cyber-risk.

The job description of a campus fire safety official is linked below offers some insight into why fire safety technologies reach into every risk dimension:

University of California Santa Cruz Office of Emergency Services

University of Tennessee Emergency Service Training

The development of the highest level fire safety consensus product in the world is led by the British Standards Institute, under the administration of the International Standardization Organization, with Committee E05 on Fire Standards of  ASTM International as the US Technical Advisory Group Administrator.  The business plan and the map of global participants is linked below:

BUSINESS PLAN ISO/TC 92 Fire safety EXECUTIVE SUMMARY

The consensus products developed by TC 92 are intended to save lives, reduce fire losses, reduce technical barriers to trade, provide for international harmonization of tests and methods and bring substantial cost savings in design. ISO/TC 92 standards are expected to be of special value to developing countries, which are less likely to have national standards.  As with all ISO standards, the TC 92 consensus product is a performance standard suitable for use in prescriptive regulations and provide for a proven route to increased fire safety.

We do not advocate in this standard at the moment; we only track it.  The International Fire Code and the Fire Code have been our priorities since 2006.  The fire safety space is well populated with knowledgeable facility professionals because conformity budgets in the fire safety world — i.e. the local or state fire marshal — usually has a budget.  When you have a budget you usually have people keeping pace with best practice.

We encourage our colleagues in the United States on either the business or academic side of the education facility industry to communicate directly with ANSI’s ISO Team and/or the ASTM Contact: Tom O’Toole, 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959 Phone: (610) 832-9739, Email: [email protected]

Reliability Analysis for Power to Fire Pump Using Fault Tree and RBD

Robert Schuerger | HP Critical Facilities (Project Lead, Corresponding Author)

Neal Dowling | MTechnology

Michael  A. Anthony | University of Michigan

 

Abstract:  One of the most common questions in the early stages of designing a new facility is whether the normal utility supply to a fire pump is reliable enough to “tap ahead of the main” or whether the fire pump supply is so unreliable that it must have an emergency power source, typically an on-site generator. Apart from the obligation to meet life safety objectives, it is not uncommon that capital on the order of 100000to1 million is at stake for a fire pump backup source. Until now, that decision has only been answered with intuition – using a combination of utility outage history and anecdotes about what has worked before. There are processes for making the decision about whether a facility needs a second source of power using quantitative analysis. Fault tree analysis and reliability block diagram are two quantitative methods used in reliability engineering for assessing risk. This paper will use a simple one line for the power to a fire pump to show how each of these techniques can be used to calculate the reliability of electric power to a fire pump. This paper will also discuss the strengths and weakness of the two methods. The hope is that these methods will begin tracking in the National Fire Protection Association documents that deal with fire pump power sources and can be used as another tool to inform design engineers and authorities having jurisdiction about public safety and property protection. These methods will enlighten decisions about the relative cost of risk control with quantitative information about the incremental cost of additional 9’s of operational availability.

2021 International Fire Code

Following the ICC Group A revision cycle public consultation on the 2024 International Fire Code will begin.  The ICC will announce the development schedule sometime in 2022.

We limit our resources simply tracking the proposals that run through Group E (Educational) and Group I (Institutional) occupancies in the Group A suite with closer attention to the state they are adopted whole cloth or with local exceptions.  In many cases, IFC adoption by state and local authorities is delayed by one or more previous code revisions.  This delay in adoption may be necessary in order for jurisdictions to evaluate the impact of changes upon the region under their authority.

Public safety budgets historically support the local and state fire marshal and his or her staff.   The revenue stream of many trade associations originates from membership, conference attendance, training and certification enterprises that service the public sector stakeholder.   Manufacturer sponsorship of trade association conferences is noteworthy.

Unless there is an idea, or proposed regulation that has run off the rails (either in terms of rigor or cost increase) — we place fire safety in the middle of our ranking of priorities.  With gathering pace, we find many fires safety goals being met with electrotechnologies where we place our highest priority.

Click on image for more information. The map is updated by expert agencies frequently so we recommend a web search for an update.

Significant code changes rarely happen within a 3-year cycle so it is wise to follow ideas as they travel through the agendas of technical committees through several cycles as administered by the Fire Code Action Committee.

The ICC posts the transcripts of public proposals, technical committee responses to public proposals, public response to the technical committee response and the final balloting in a fair and reasonable fashion as can be seen in the transcripts linked below:

2021 International Fire Code Proposed Changes

2021 International Fire Code Public Comment Agenda 

A search on the terms “classroom” or “school” in any of the documents above offers granular insight into the trend of current thinking.   We find fire extinguishers placement a perennial concern across several standards suites.   You will note the careful consideration of proposals for use of the mass notification systems, now integrated into fire alarm systems and their deployment in active shooter situations.

The transcripts reveal detailed understanding and subtlety.

“The Country School” | Winslow Homer

There are many issues affecting the safety and sustainability of the education facility industry.  We add value to the industry because of our cross-cutting perspective on the hundreds of “silos”created by the competition (and sometimes cooperation) among accredited, consortia and open-source standards developers.  We have the door open every day at 11 AM Eastern time to enlighten understanding of them all.  We also host a breakout teleconference every month to drill into the specifics of standards action on fire safety for the real assets of school districts, colleges and universities.  See our CALENDAR for the next online meeting.

Finally, we persist in encouraging education industry facility managers (especially those with operations and maintenance data) to participate in the ICC code development process.  You may do so by CLICKING HERE.

The ICC Group B Code Meetings will be hosted soon and open to the public:   

International Code Council 2022 Group B Public Comment Agenda (September 14-21 Kentucky International Convention Center)

The Group B tranche is largely focused on energy, structural, residential and existing building concepts but all of the titles cross-reference the IFC in some way so it is wise to follow how the concepts re-arrange and cross-reference themselves with each cycle.

“Dutch Kitchen” / Artist Unknown

A noteworthy title in the ASHRAE standards catalog is ASHRAE 154 Ventilation for Commercial Cooking Operations.  Food preparation enterprises in school districts, residence halls, hospitals and athletic venues and central features in education communities.   Access to the 2022 edition is linked below:

FREE ACCESS ASHRAE 154

The purpose of ASHRAE 154 is to provide design criteria for the performance of commercial cooking ventilation systems.  It covers kitchen hoods, exhaust systems and replacement air systems,   It is not intended to circumvent any safety, health or environmental requirement; however we find a fair amount of drama between partisans of air movement controls and energy conservation interests.  Fire safety and the sustainability advocates are well funded voices.

There are no open consultations at the moment; but you may track release of any at the link below:

Public Review Draft Standards / Online Comment Database

Titles in the ASHRAE catalog move swiftly; many of them consultations lasting less than 45 days.

Interior environmental air safety is a concern that cuts across many professional disciplines.  Accordingly, we maintain this title on the standing agendas of several colloquia — Mechanical Engineering, Energy and Housing.  Starting 2022 we will break out this the subject of a separate, dedicated colloquium   See our CALENDAR for the next online meeting; open to everyone.

Use search terms such as school, college, university, dormitory(ies), laboratory(ies), classroom, children, day-care, student, et cetera for a sense of the ideas in play.

Results of the 2027 First Draft meetings have not yet been posted as on November 9, 2024.  A preview of the ideas in play can be found in the meeting minutes of the several committees linked below:

Fire Code (FCC-AAC): First Draft Meeting Minutes

First Draft: Fundamentals of the Fire Code (FCC-FUN)

Special Equipment, Processes and Hazardous Materials (FCC-HAZ)

Building Systems and Special Occupancies (FCC-OCP)

Public comment on the First Draft of the 2027 revision will be received until April 24, 2025.

We include NFPA 1 on our periodic fire safety colloquia — identified by the mnemonic Prometheus — and march along peak interests.

Campus fire safety is domain relatively well-covered by other organizations such as the Center for Campus Fire Safety and HigherEd Safety so we place NFPA 1 in the middle of our priority tier.   We are more interested in the harmonization of NFPA 1 with a competitor title International Fire Code; published by the International Code Council; to wit:

International Fire Code:   The purpose of this code is to establish the minimum requirements consistent with nationally recognized good practice for proving a reasonable level of life safety and property protection from the hazards of fire, explosion or dangerous conditions in new and existing buildings, structures or premises and to provide a reasonable level of safety to fire fighters and emergency responders during emergency operations

Fire Code: The scope includes, but is not limited to, the following: (1) Inspection of permanent and temporary buildings, processes, equipment, systems, and other fire and related life safety situations (2) Investigation of fires, explosions, hazardous materials incidents, and other related emergency incidents (3) Review of construction plans, drawings, and specifications for life safety systems, fire protection systems, access, water supplies, processes, hazardous materials, and other fire and life safety issues (4) Fire and life safety education of fire brigades, employees, responsible parties, and the general public (5) Existing occupancies and conditions, the design and construction of new buildings, remodeling of existing buildings, and additions to existing buildings (6) Design, installation, alteration, modification, construction, maintenance, repairs, servicing, and testing of fire protection systems and equipment (7) Installation, use, storage, and handling of medical gas systems (8) Access requirements for fire department operations (9) Hazards from outside fires in vegetation, trash, building debris, and other materials (10) Regulation and control of special events including, but not limited to, assemblage of people, exhibits, trade shows, amusement parks, haunted houses, outdoor events, and other similar special temporary and permanent occupancies (11) Interior finish, decorations, furnishings, and other combustibles that contribute to fire spread, fire load, and smoke production (12) Storage, use, processing, handling, and on-site transportation of flammable and combustible gases, liquids, and solids (13) Storage, use, processing, handling, and on-site transportation of hazardous materials (14) Control of emergency operations and scenes (15) Conditions affecting fire fighter safety (16) Arrangement, design, construction, and alteration of new and existing means of egress

Note that both ICC and NFPA parent fire safety documents are developed on coincident 3-year cycles.

“Weather is fate”

— Charles Louis de Secondat, Baron de La Brède et de Montesquieu

“Road to Versailles at Louveciennes” 1869 Camille Pissarro

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.

Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.

There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.

Today we review the literature for snow and ice management (and enjoyment) produced by these standards-setting organizations:

There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:

  1. Heated Job Site Trailers: These trailers are equipped with heating systems that keep workers warm and comfortable while they take breaks or work on plans. This helps to keep morale up and prevent cold-related health issues.
  2. Insulated Concrete Forms (ICFs): ICFs are prefabricated blocks made of foam insulation that are stacked together to form the walls of a building. The foam insulation provides an extra layer of insulation to keep the building warm during cold winter months.
  3. Warm-Mix Asphalt (WMA): WMA is a type of asphalt that is designed to be used in colder temperatures than traditional hot-mix asphalt. This allows road construction crews to work through the winter months without having to worry about the asphalt cooling and becoming unusable.
  4. Pneumatic Heaters: These heaters are used to warm up the ground before concrete is poured. This helps to prevent the concrete from freezing and becoming damaged during the winter months.
  5. Electrically Heated Mats: These mats are placed on the ground to prevent snow and ice from accumulating. This helps to make the job site safer and easier to work on during the winter months.

Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.
