Emergency sound systems at sports venues

University of Bolton Lancashire

A rare find in best practice literature is a title that slices horizontally through a number of “silos” owned by US-based domain incumbents such as NFPA, ICC, IEEE and others.  Several occupancy classifications run interstitially and present challenging risk aggregations–similarly recognized in the EU–when 100,000 people must be put out of harms way in less than 60 seconds.  One such title is Code of Practice: BS 7827 Designing, specifying, maintaining and operating emergency sound systems for sports grounds, large public buildings, and venues.  From the project prospectus:

Maintenance, Emergency measures, Safety devices, Reports, Crowd safety, Certification (approval), Inspection, Audio systems, Forms (paper), Speech transmission systems, Reliability, Instructions for use, Personnel, Sound intensity, Approval testing, Training, Audio equipment, Performance, Stadia, Warning devices, Electric power systems, Alarm systems, Signal distortion, Sports facilities, Safety measures, Public-address systems, Audibility, Acoustic measurement, Reception, Sound reproduction, Buildings, Control panels

The current 2019 Edition was released October 2019 and is assumed to be stable.  You can tell by the list of normative references from European Union standards developers that event safety is an established discipline and one that requires continual attention despite the circumstances of the pandemic.

Michigan Stadium is the largest university-owned sports venue in the world. with nominal seating capacity of 110,000 and auxiliary enterprises that add another 20,000.

More information about how our colleagues may contribute to the development of future revisions to this titles should communicate directly with BSI Group Technical Committee EPL/100.  We collaborate with European Union electrotechnical professionals through the IEEE Education & Healthcare Facilities Committee which meets online 4 times monthly in European and American time zones.

We maintain this title on the standing agenda of our Sport and Global colloquia.  See our CALENDAR for the next online meeting; open to everyone.

Life Safety Code

The Life Safety Code addresses those construction, protection, and occupancy features necessary to minimize danger to life from the effects of fire, including smoke, heat, and toxic gases created during a fire.   It is widely incorporated by reference into public safety statutes; typically coupled with the consensus products of the International Code Council.   It is a mighty document — one of the NFPA’s leading titles — so we deal with it in pieces; consulting it for decisions to be made for the following:

(1) Determination of the occupancy classification in Chapters 12 through 42.

(2) Determination of whether a building or structure is new or existing.

(3) Determination of the occupant load.

(4) Determination of the hazard of contents.

There are emergent issues — such as active shooter response, integration of life and fire safety systems on the internet of small things — and recurrent issues such as excessive rehabilitation and conformity criteria and the ever-expanding requirements for sprinklers and portable fire extinguishers with which to reckon.  It is never easy telling a safety professional paid to make a market for his product or service that it is impossible to be alive and safe.  It is even harder telling the dean of a department how much it will cost to bring the square-footage under his stewardship up to the current code.

The 2021 edition is the current edition and is accessible below:

NFPA 101 Life Safety Code Free Public Access

Public input on the 2027 Revision will be received until June 4, 2024.  Public comment on the First Draft of the 2027 Revision will be received until June 3, 2025.

 

Since the Life Safety Code is one of the most “living” of living documents — the International Building Code and the National Electric Code also move continuously — we can start anywhere and anytime and still make meaningful contributions to it.   We have been advocating in this document since the 2003 edition in which we submitted proposals for changes such as:

• A student residence facility life safety crosswalk between NFPA 101 and the International Building Code

• Refinements to Chapters 14 and 15 covering education facilities (with particular attention to door technologies)

• Identification of an ingress path for rescue and recovery personnel toward electric service equipment installations.

• Risk-informed requirement for installation of grab bars in bathing areas

• Modification of the 90-minute emergency lighting requirements rule for small buildings and for fixed interval testing

• Modification of emergency illumination fixed interval testing

• Table 7.3.1 Occupant Load revisions

• Harmonization of egress path width with European building codes

There are others.  It is typically difficult to make changes to stabilized standard though some of the concepts were integrated by the committee into other parts of the NFPA 101 in unexpected, though productive, ways.  Example transcripts of proposed 2023 revisions to the education facility chapter is linked below:

Chapter 14 Public Input Report: New Educational Occupancies

Educational and Day Care Occupancies: Second Draft Public Comments with Responses Report

Since NFPA 101 is so vast in its implications we list a few of the sections we track, and can drill into further, according to client interest:

Chapter 3: Definitions

Chapter 7: Means of Egress

Chapter 12: New Assembly Occupancies

Chapter 13: Existing Assembly Occupancies

Chapter 16 Public Input Report: New Day-Care Facilities

Chapter 17 Public Input Report: Existing Day Care Facilities

Chapter 18 Public Input Report: New Health Care Facilities

Chapter 19 Public Input Report: Existing Health Care Facilities

Chapter 28: Public Input Report: New Hotels and Dormitories

Chapter 29: Public Input Report: Existing Hotels and Dormitories

Chapter 43: Building Rehabilitation

Annex A: Explanatory Material

As always we encourage front-line staff, facility managers, subject matter experts and trade associations to participate directly in the NFPA code development process (CLICK HERE to get started)

NFPA 101 is a cross-cutting title so we maintain it on the agenda of our several colloquia —Housing, Prometheus, Security and Pathways colloquia.  See our CALENDAR for the next online meeting; open to everyone.

Recreational sports, athletic competition, and the facilities that support it, are one of the most visible activities in any school, college or university in any nation.  Arguably, these activities resemble religious belief and practice.   Enterprises of this kind have the same ambition for safety and sustainability at the same scale as the academic and healthcare enterprises.  

According to IBISWorld Market Research, Sports Stadium Construction was a $6.1 billion market in 2014, Athletic & Sporting Goods Manufacturing was a $9.2 billion market in 2015, with participation in sports increasing 19.3 percent by 2019 — much of that originating in school, college and university sports and recreation programs.  We refer you to more up to date information in the link below:

Today at the usual time we will update our understanding of the physical support systems for the track and field activity listed below:

  1. Sprinting: Races over short distances, typically 100m, 200m, and 400m.
  2. Middle-distance running: Races covering distances between sprinting and long-distance running, such as 800m and 1500m.
  3. Long-distance running: Races over longer distances, including 3000m, 5000m, 10,000m, and marathons.
  4. Hurdling: Races where athletes jump over hurdles at set distances, such as 110m hurdles (for men) and 100m hurdles (for women).
  5. Steeplechase: A long-distance race that includes hurdles and a water jump.
  6. Racewalking: A form of walking competition where athletes race over various distances while maintaining contact with the ground.
  7. Relays: Team races where athletes take turns running a specified distance before passing a baton to the next runner. Common relay distances include 4x100m and 4x400m.
  8. High jump: Athletes attempt to jump over a horizontal bar placed at measured heights without knocking it down.
  9. Pole vault: Athletes use a pole to vault themselves over a high bar.
  10. Long jump: Athletes sprint down a runway and jump as far as possible into a sandpit.
  11. Triple jump: Athletes perform a hop, step, and jump sequence into a sandpit, with distances measured from the takeoff board to the nearest mark made in the sand by any part of the body.
  12. Shot put: Athletes throw a heavy metal ball for distance.
  13. Discus throw: Athletes throw a discus, a heavy circular object, for distance.
  14. Javelin throw: Athletes throw a javelin, a spear-like object, for distance.
  15. Hammer throw: Athletes throw a heavy metal ball attached to a wire and handle for distance.
  16. Decathlon (men) / Heptathlon (women): Multi-event competitions where athletes compete in ten (decathlon) or seven (heptathlon) different track and field events, with points awarded for performance in each event.

Theatre: Lighting Design

Artificial lighting was first introduced to theater dramatic performance stages in the 17th century. The use of candles and oil lamps initially provided a means to illuminate the stage, allowing performances to take place in the evening and enhancing the visibility for both actors and the audience. Before this development, theatrical performances were typically held during daylight hours due to the reliance on natural light.

In the early 17th century, theaters in England began experimenting with various lighting techniques. Thomas Killigrew’s Theatre Royal, Drury Lane, in London, is often credited as one of the first theaters to use artificial lighting. The use of candles and later oil lamps evolved over time, leading to more sophisticated lighting setups as technology advanced.

The 18th and 19th centuries saw further innovations in stage lighting, including the use of gas lamps. Eventually, the introduction of electric lighting in the late 19th and early 20th centuries revolutionized stage lighting, providing theaters with a more reliable and controllable source of illumination. This allowed for greater creativity in the design and execution of lighting effects, contributing significantly to the overall theatrical experience.
