Clean the chicken, put it in a large pot and cover it with cold water. Bring the water to boil.
Add the chicken wings, onions, sweet potato, parsnips, turnips and carrots. Boil about 1 and a half hours. Remove fat from the surface as it accumulates.
Add the parsley and celery. Cook the mixture about 45 min. longer.
Remove the chicken. The chicken is not used further for the soup. (The meat makes excellent chicken parmesan.)
Put the vegetables in a food processor until they are chopped fine or pass through a strainer. Both were performed in the present study.
Add salt and pepper to taste.
(Note: This soup freezes well.) Matzo balls were prepared according to the recipe on the back of the box of matzo meal (Manischewitz).

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. Without electric heat tracing; much of the earth would be uninhabitable.
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.
It is a surprisingly large domain with market-makers in every dimension of safety and sustainability; all of whom are bound by state and federal regulations.

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:
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.
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.
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.
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.
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.

One of the core documents for heat tracing is entering a new 5-year revision cycle; a consensus standard that is especially relevant this time of year because of the personal danger and property damage that is possible in the winter months. Education communities depend upon heat tracing for several reasons; just a few of them listed below:
Ice damming in roof gutters that can cause failure of roof and gutter structural support
Piping systems for sprinkler systems and emergency power generation equipment
This standard provides requirements for the testing, design,installation, and maintenance of electrical resistance trace heating in general industries as applied to pipelines, vessels, pre-traced and thermally insulated instrument tubing and piping, and mechanical equipment. The electrical resistance trace heating is in the form of series trace heaters, parallel trace heaters, and surface heating devices. The requirements also include test criteria to determine the suitability of these heating devices utilized in unclassified (ordinary) locations.
Its principles can, and should be applied with respect to other related documents:
We are happy to explain the use of this document in design guidelines and/or construction specifications during any of our daily colloquia. We generally find more authoritative voices in collaborations with the IEEE Education & Healthcare Facilities Committee which meets 4 times per month in Europe and in the Americas. We maintain this title on the standing agenda of our Snow & Ice colloquia. See our CALENDER for the next online meeting.
Much of our assertion that building construction in education communities resembles a perpetual motion machine rests upon innovation in a broad span of technologies that is effectively weather resistant; that along with development of construction scheduling. Today at 16:0 UTC we review the technical, management and legal literature that supports safe and sustainable construction,
1. Cold-Weather Concrete Technology
Accelerating Admixtures: These are chemical additives that speed up the curing process of concrete, allowing it to set even in low temperatures.
Heated Concrete Blankets: Electric blankets that maintain a consistent temperature around freshly poured concrete.
Hot Water Mixing: Using heated water during the mixing process to ensure that concrete maintains the proper temperature for curing.
Air-Entrained Concrete: Helps resist freeze-thaw cycles by creating tiny air pockets in the concrete.
2. Temporary Heating Solutions
Portable Heaters: Diesel, propane, or electric heaters used to maintain a warm environment for workers and materials.
Enclosed Workspaces: Temporary enclosures (tents or tarps) around construction areas retain heat and shield against snow and wind.
3. Advanced Building Materials
Cold-Weather Asphalt: Modified asphalt that can be laid at lower temperatures.
Pre-fabricated Components: Factory-assembled parts (walls, beams) that reduce on-site work in harsh conditions.
4. Insulation Techniques
Insulated Tarps and Blankets: Used to cover construction materials and newly laid concrete to prevent freezing.
Frost-Protected Shallow Foundations: Insulation techniques to keep ground temperatures stable and prevent frost heave.
5. Ground Thawing Technologies
Hydronic Ground Heaters: Circulate heated fluid through hoses laid on frozen ground to thaw it before excavation or foundation work.
Steam Thawing: Direct steam application to melt snow or thaw frozen soil.
6. Lighting Solutions
High-Intensity LED Lights: Compensate for reduced daylight hours to ensure safe and efficient work conditions.
7. Weather-Resistant Machinery
Winterized Equipment: Construction equipment with heated cabins, antifreeze systems, and enhanced traction for icy conditions.
8. Workforce Adaptations
Cold-Weather Gear: Heated clothing, gloves, and footwear keep workers safe and productive.
Modified Work Schedules: Shorter shifts or daytime-only work to limit exposure to extreme cold.
9. Snow and Ice Management
Deicing Solutions: Chemical deicers and mechanical snow-removal equipment keep work areas safe and accessible.
Heated Surfaces: Embedded heating systems in ramps or entryways prevent ice buildup.
The Occupational Safety and Health Administration does not have a specific regulation solely dedicated to building construction in cold winter weather. However, several OSHA standards and guidelines are applicable to address the hazards and challenges of winter construction work. These regulations focus on worker safety, protection from cold stress, proper equipment use, and general site safety. Key applicable OSHA regulations and guidance include:
1. Cold Stress and Temperature Exposure
General Duty Clause (Section 5(a)(1)): Employers are required to provide a workplace free from recognized hazards likely to cause death or serious physical harm. This includes addressing cold stress hazards, such as hypothermia, frostbite, and trench foot.
OSHA Cold Stress Guide: OSHA provides guidance on recognizing, preventing, and managing cold stress but does not have a specific cold stress standard.
2. PPE (Personal Protective Equipment)
29 CFR 1926.28: Requires employers to ensure the use of appropriate personal protective equipment.
29 CFR 1910.132: General requirements for PPE, including insulated gloves, boots, and clothing to protect against cold weather.
3. Walking and Working Surfaces
29 CFR 1926.501: Fall Protection in Construction. Ice and snow can increase fall risks, so proper precautions, including removal of hazards and use of fall protection systems, are required.
29 CFR 1926.451: Scaffolding. Specific safety measures must be implemented to ensure stability and secure footing in icy conditions.
4. Snow and Ice Removal
Hazard Communication Standard (29 CFR 1910.1200): Ensures workers are informed about hazards related to de-icing chemicals or other substances used in winter construction.
5. Powered Equipment
29 CFR 1926.600: Equipment use, requiring machinery to be properly maintained and adjusted for cold-weather operations, including anti-freeze measures and winterization.
6. Excavations and Frost Heave
29 CFR 1926.651 and 1926.652: Excavation standards. Frozen ground and frost heave pose additional risks during trenching and excavation activities.
7. Temporary Heating
29 CFR 1926.154: Requirements for temporary heating devices, including ventilation and safe usage in confined or enclosed spaces.
8. Illumination
29 CFR 1926.56: Lighting standards to ensure sufficient visibility during reduced daylight hours in winter.
9. Emergency Preparedness
First Aid (29 CFR 1926.50): Employers must ensure quick access to first aid, especially critical for treating cold-related illnesses or injuries.
10. Hazard Communication and Training
29 CFR 1926.21(b): Employers must train employees on recognizing winter hazards, such as slips, trips, falls, and cold stress.
By following these OSHA standards and implementing additional best practices (e.g., scheduling breaks in heated shelters, providing warm beverages, and encouraging layered clothing), employers can ensure a safer construction environment during winter conditions.

Today we run a status check on the stream of technical and management standards evolving to assure the highest possible level of security in education communities. The literature expands significantly from an assortment of national standards-setting bodies, trade associations, ad hoc consortia and open source standards developers. CLICK HERE for a sample of our work in this domain.
School security is big business in the United States. According to a report by Markets and Markets, the global school and campus security market size was valued at USD 14.0 billion in 2019 and is projected to reach USD 21.7 billion by 2025, at a combined annual growth rate of 7.2% during the forecast period.
Another report by Research And Markets estimates that the US school security market will grow at a compound annual growth rate of around 8% between 2020 and 2025, driven by factors such as increasing incidents of school violence, rising demand for access control and surveillance systems, and increasing government funding for school safety initiatives.
Because the pace of the combined annual growth rate of the school and campus security market is greater than the growth rate of the education “industry” itself, we’ve necessarily had to break down our approach to this topic into modules:
Security 100. A survey of all the technical and management codes and standards for all educational settings — day care, K-12, higher education and university affiliated healthcare occupancies.
Security 200. Queries into the most recent public consultations on the components and interoperability* of supporting technologies
Video surveillance: indoor and outdoor cameras, cameras with night vision and motion detection capabilities and cameras that can be integrated with other security systems for enhanced monitoring and control.
Access control:doors, remote locking, privacy and considerations for persons with disabilities.
Panic alarms: These devices allow staff and students to quickly and discreetly alert authorities in case of an emergency.
Metal detectors: These devices scan for weapons and other prohibited items as people enter the school.
Mass notification systems: These systems allow school administrators to quickly send emergency alerts and notifications to students, staff, and parents.
Intrusion detection systems: These systems use sensors to detect unauthorized entry and trigger an alarm.
GPS tracking systems: These systems allow school officials to monitor the location of school buses and track the movements of students during field trips and other off-campus activities.
Security 300. Regulatory and management codes and standards; a great deal of which are self-referencing.
As always, we reckon first cost and long-term maintenance cost, including software maintenance for the information and communication technologies (i.e. anything with wires) installed in the United States. Cybersecurity is outside our wheelhouse and beyond our expertise. In order to do any of the foregoing reasonably well, we have to leave cybersecurity standards to others.

Education Community Safety catalog is one of the fast-growing catalogs of best practice literature. In developing district security plans, K-12 school leaders stress that school safety is a cross-functional responsibility and every individual’s participation drives the success of overall safety protocols. We link a small sample below and update ahead of every Security colloquium.
* Interoperability refers to the ability of different technologies or systems to communicate and work together seamlessly. In the context of school security technologies, interoperability can help improve the effectiveness of security systems and make it easier for school personnel to manage and respond to potential security threats. Here’s what we look for:
Standardization: By standardizing communication protocols and data formats, school security technologies can be made more compatible with each other, making it easier for different systems to communicate and share information.
Integration: School security technologies can be integrated with each other to provide a more comprehensive security solution. For example, access control systems can be integrated with video surveillance systems to automatically trigger alerts when an unauthorized person enters a restricted area.
Open Architecture: Open architecture solutions enable different security systems to be connected and communicate with each other regardless of their manufacturer or supplier. This approach makes it easier to integrate different technologies and avoid vendor lock-in.
Cloud-based Solutions: Cloud-based security solutions can enable interoperability by providing a centralized platform for managing and monitoring different security systems. This approach can also simplify the deployment of security technologies across multiple locations.
Collaboration: School security technology providers can work together to develop interoperability standards and best practices that can be adopted across the industry. Collaboration can help drive innovation and improve the effectiveness of security systems.

ABSTRACT. The horrific and tragic deaths that have resulted from infamous school shootings have deprived Americans of the sense of security in what has traditionally been a nurturing and safe environment. This paper will discuss different preventive methods for school shootings. The most current preventive methods are examined for fitness based on a variety of school shootings that have occurred in the past. Then a framework for a new school shooting protection device is proposed and evaluated. Concepts from computer vision, anomaly detection, and electromagnetic propulsion are discussed with respect to the proposed framework. Ideally, the goal of the framework presented in this paper is to prevent deaths and injuries from occurring during a school shooting. With the framework, an efficient and comparatively affordable preventive method could be released in the near future.
