A standard water polo pool playing field has specific characteristics and dimensions regulated by the sport’s governing bodies, such as Fédération Internationale de Natation with regional variations informed by student athlete safety. There are about 750 high school girls and boys girls water polo programs in the US and about 70 collegiate teams.  Here are the key features:

Pool Dimensions

  1. Length: The playing area is typically 20 to 30 meters long.
  2. Width: The playing area is 10 to 20 meters wide.
  3. Depth: The minimum depth is 1.8 meters (about 6 feet) to ensure players cannot touch the bottom.

Goal Dimensions

  1. Width: The goals are 3 meters wide.
  2. Height: The goals are 0.9 meters high.

Markings and Zones

  1. Midline: The center of the pool has a midline to divide the playing area into two halves.
  2. 5-Meter Line: There are lines marked at 5 meters from each goal line, used to indicate where penalty shots can be taken.
  3. 2-Meter Line: There are lines marked at 2 meters from each goal line, inside which attacking players cannot remain for more than a few seconds without the ball.

Goals and Nets

  1. Goalposts and Crossbar: The goals are constructed with goalposts and a crossbar, usually made of metal or a similar sturdy material.
  2. Nets: Attached to the goals to catch the ball.

Ball Specifications

  1. Size: The ball has a circumference of 0.68 to 0.71 meters for men and 0.65 to 0.67 meters for women.
  2. Weight: The ball weighs between 400 and 450 grams.

Additional Features

  1. Team Benches: Located on the pool deck for players not in the water.
  2. Shot Clocks: To keep track of the possession time, typically set to 30 seconds.
  3. Scoreboards: To display the game score, time remaining, and other relevant information.

Water Temperature

  1. Temperature: The water temperature is usually maintained between 25-28°C (77-82°F) to ensure player comfort.

LIVECAM: Timber Construction

Timber construction offers numerous benefits for university buildings, combining sustainability, aesthetics, and functionality. One of the primary advantages is its environmental impact. Timber is a renewable resource, and modern forestry practices ensure sustainable harvesting. Timber construction also has a lower carbon footprint compared to steel or concrete, as it sequesters carbon dioxide, helping mitigate climate change.

Aesthetically, timber provides a warm, natural look that can enhance the campus environment, creating inviting and inspiring spaces for students and faculty. It can be used in various architectural styles, from traditional to contemporary, offering versatility in design.

Functionally, timber is a strong and durable material. Engineered wood products, such as cross-laminated timber (CLT), provide excellent structural integrity, allowing for larger spans and innovative architectural designs. Timber construction is often faster than traditional methods, reducing construction time and minimizing disruption on campus.

Additionally, timber buildings offer superior thermal insulation properties, contributing to energy efficiency and reducing heating and cooling costs. The acoustic properties of wood also enhance the learning environment by dampening noise and creating quieter spaces.

Mercer County is famous for the Battle of Trenton during the American Revolutionary War. On December 26, 1776, General George Washington led a surprise attack across the Delaware River, resulting in a crucial victory against the Hessian forces stationed in Trenton. This victory boosted the morale of the Continental Army and is considered a turning point in the Revolutionary War.

“The Alchemists Laboratory” 1625 | Heinrich Khunrath

The size of the U.S. Testing, Inspection, and Certification (TIC) industry is approximately $48.19 billion in 2023 and is projected to grow to about $60.06 billion by 2032.  The industry is driven by factors such as increasing government regulatory action, consumer awareness about safety, and the rising need for quality assurance in various sectors like automotive, healthcare, consumer goods, municipal and campus building construction.  TIC standards are found in design guidelines, construction contracts, building commissioning and acceptance.

Today we focus on the public commenting facilities of the dominant standards developers relevant to our work:

ASTM International

Intertek

International Electrical Testing Association (Portage, Michigan)

NSF International (Ann Arbor, Michigan)

Underwriters Laboratories

Each of the foregoing organizations have global affiliates such as SGS, Bureau Veritas, and TÜV SÜD which we cover in a separate session at some point in the future.  We deal with electrotechnical TIC standards in any of our electrotechnology-oriented sessions every Tuesday.

EPRI is an independent, nonprofit organization that is primarily funded by its member utilities. These member utilities are typically electric power companies, and they contribute financially to EPRI to support its research and development activities.

While EPRI is not directly funded by the government, it does collaborate with various government agencies on research projects and receives funding for specific initiatives through government grants and contracts. Additionally, some of EPRI’s research and development efforts align with government priorities in areas such as renewable energy, environmental sustainability, and grid modernization.

Electrical inspectors (See NFPA 1078) typically do not have jurisdiction over electrical power plants. Electrical power plants, especially large-scale utility power plants, are subject to much more stringent regulations and oversight than regular electrical installations. The responsibility for inspecting and ensuring the safety and compliance of power plants falls under various government agencies and organizations.

In the United States, for example, power plants are subject to federal regulations set forth by the U.S. Nuclear Regulatory Commission (NRC) for nuclear power plants or the U.S. Environmental Protection Agency (EPA) for fossil fuel power plants. Additionally, state regulatory agencies and utility commissions may have their own specific requirements and oversight for power plants within their jurisdictions.

Power plants typically undergo rigorous inspections and audits to ensure compliance with safety, environmental, and operational standards. These inspections are conducted by specialized teams of engineers, experts, and representatives from relevant regulatory bodies and utilities.

While electrical inspectors may not have jurisdiction over power plants, they play a crucial role in inspecting and ensuring the safety of electrical installations in other settings, such as smaller power generation facilities (i.e. district energy plants) that are not exempted by self-assessment charters granted to many large university power plants.

“Stand up for your friends especially when they’re right.  There is every reason in the world to do so but one is not obvious — although perhaps it should be — and it’s this:  it might be the only chance you get to show them how much they mean to you if you don’t seize this opportunity whenever it comes along. 

To save the truth of your feelings for their funeral or obituaries it’s not much use to anyone then but if you defend a friend while they’re alive you might just give them the slightest intimation of how much you value them and love them and how much other people love them too…”

Douglas Murray
