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:

Master Plan: Vision 2030

The United States Food and Drug Administration and the National Coffee Association recommended standard temperature for safe hot coffee is around 160°F to 165°F (71°C to 74°C). This temperature range is considered hot enough to be enjoyable while minimizing the risk of scalding or burning.

These agencies do not have specific regulations or guidelines solely dedicated to cold brew coffee.  However, there are general principles and best practices for handling and storing perishable food products that can be applied to cold brew coffee to ensure safety.*

Cold brew coffee typically requires more time to prepare than traditional hot brew coffee. While hot brew coffee can be made in just a few minutes, cold brew coffee is made by steeping coffee grounds in cold water for an extended period of time, usually between 12 to 24 hours.

The longer steeping time allows the coffee to extract more slowly and results in a smoother, less acidic coffee concentrate. After steeping, the coffee grounds are usually filtered out and the resulting concentrate can be diluted with water, milk, or other liquids and served over ice.

While cold brew coffee does require more time to prepare, many coffee drinkers prefer its smoother, less bitter taste and lower acidity compared to hot brewed coffee. Additionally, the longer shelf life of cold brew coffee concentrate makes it a popular choice for those who like to prepare coffee in advance and have it ready to drink throughout the day.

* These recommendations are based on general food safety practices:

Water quality: Start with clean, potable water to brew your cold brew coffee. Make sure the water source is safe and free from contaminants.

Brewing process: Follow good manufacturing practices and ensure that your brewing equipment and utensils are clean and sanitized. Cold brew coffee is typically brewed using room temperature or cold water over an extended period. Ensure that the brewing container is properly sealed and protected from any potential sources of contamination.

Filtration: After the brewing process, filter the cold brew coffee to remove any sediment or particles. This can be done using a fine-mesh sieve or a dedicated filtration system.

Storage: Store the cold brew coffee in a clean, airtight container in the refrigerator. This helps to inhibit the growth of bacteria and maintain the quality of the coffee. Cold brew coffee can typically be stored for a few days to a couple of weeks, depending on the specific recipe and preparation method.

Temperature control: Keep the cold brew coffee refrigerated at a temperature below 41°F (5°C) to prevent the growth of harmful bacteria.

Serve safely: When serving cold brew coffee, use clean and sanitized utensils, containers, and dispensing equipment to avoid cross-contamination. If you add any additional ingredients like milk or sweeteners, ensure that they are stored properly and do not exceed their recommended storage times.

Charcuterie

Charcuterie refers to a variety of cured meats, often accompanied by an assortment of cheeses, fruits, nuts, bread, and spreads. Originating from France, charcuterie was initially focused solely on prepared meat products, such as sausages, pâtés, and confits. Today, a charcuterie board is a popular way to serve an array of meats and complementary foods in a visually appealing and flavorful arrangement as demonstrated here for the Office of Alumni and Family Engagement by Alaura Westrol, Class of 2011.

FIREWORKS: PYROTECHNIC ARTS AND SCIENCES IN EUROPEAN HISTORY

Simon Werrett | University College London

Fireworks are synonymous with celebration in the twenty-first century. But pyrotechnics—in the form of rockets, crackers, wheels, and bombs—have exploded in sparks and noise to delight audiences in Europe ever since the Renaissance. Here, Simon Werrett shows that, far from being only a means of entertainment, fireworks helped foster advances in natural philosophy, chemistry, mathematics, and many other branches of the sciences.

Fireworks brings to vibrant life the many artful practices of pyrotechnicians, as well as the elegant compositions of the architects, poets, painters, and musicians they inspired. At the same time, it uncovers the dynamic relationships that developed between the many artists and scientists who produced pyrotechnics. In so doing, the book demonstrates the critical role that pyrotechnics played in the development of physics, astronomy, chemistry and physiology, meteorology, and electrical science. Richly illustrated and drawing on a wide range of new sources, Fireworks takes readers back to a world where pyrotechnics were both divine and magical and reveals for the first time their vital contribution to the modernization of European ideas.
