An American hot sandwich originally created at the Brown Hotel in Louisville, Kentucky, by Fred K. Schmidt in 1926. It is a variation of traditional Welsh rarebit and was one of two signature sandwiches created by chefs at the Brown Hotel shortly after its founding in 1923. It was created to serve as an alternative to ham and egg late-night dinners requested by its guests in the early hours of the morning after an evening of dancing; its ballroom accommodating upwards 1200 guests.
When the electric grid and the internet are down and there is no cell service, radio can still work to help communities stabilize. Starting 2024 we will break down our coverage of the radio frequency technology standards used in educational settlements into into two categories:
Radio 300: Security and maintenance radio. These usually use a single radio channel and operate in a half-duplex mode: only one user on the channel can transmit at a time, so users in a user group must take turns talking. The radio is normally in receive mode so the user can hear all other transmissions on the channel. When the user wants to talk he presses a “push-to-talk” button, which turns off the receiver and turns on the transmitter; when he releases the button the receiver is activated again. Multiple channels are provided so separate user groups can communicate in the same area without interfering with each other.
Radio 400: Student radio. College radio stations are typically considered to be public radio radio stations in the way that they are funded by donation and grants. The term “Public radio” generally refers to classical music, jazz, and news. A more accurate term is community radio, as most staff are volunteers, although many radio stations limit staff to current or recent students instead of anyone from the local community. There has been a fair amount of drama over student-run radio station history; a topic we steer away from.
The Low Power FM radio service was created by the Commission in January 2000. LPFM stations are authorized for noncommercial educational broadcasting only (no commercial operation) and operate with an effective radiated power (ERP) of 100 watts (0.1 kilowatts) or less, with maximum facilities of 100 watts ERP at 30 meters (100 feet) antenna height above average terrain. The approximate service range of a 100 watt LPFM station is 5.6 kilometers (3.5 miles radius). LPFM stations are not protected from interference that may be received from other classes of FM stations.
We follow — but do not respond — to consultations on titles covering the use of radio frequencies for the Internet of Things. At the moment, most of that evolution happens at the consumer product level; though it is wise to contemplate the use of the electromagnetic spectrum during widespread and extended loss of broadband services.

We do not include policy specifics regarding the migration of National Public Radio beyond cultural content into political news; though we acknowledge that the growth of publicly financed radio domiciled in education communities is a consideration in the technology of content preparation informed by the Public Broadcasting Act of 1967.
We drill into technical specifics of the following:
Radios used for campus public safety and campus maintenance
Student-run campus radio stations licensed by the Federal Communications Commission as Low Power FM (LPFM)
Facilities for regional broadcast of National Public Radio operating from education communities
Off-campus transmission facilities such as broadcast towers.
Grounding, bonding, lightning protection of transmission and receiving equipment on buildings
Broadcast studio electrotechnologies
Radio technology is regulated by the Federal Communications Commission with no ANSI-accredited standards setting organizations involved in leading practice discovery and promulgation.

In any industry painting (and decorating) operations play a crucial role in facility management by enhancing the overall appearance, protecting surfaces, and maintaining a healthy and conducive environment. In the education industry we find these operations in both the business and academic units; often co-mingled with sign-making shops.
Aesthetics and Branding: Fresh coats of paint revitalize the appearance of walls, ceilings, doors, and other surfaces, creating a clean and inviting environment. Painting can also be used strategically to incorporate branding elements, such as company colors or logos, to reinforce brand identity throughout campus. Bright, vibrant colors can stimulate creativity and engagement, while well-chosen color schemes can create a sense of calm and focus.
Surface Protection: Color coatings are a protective barrier for surfaces, shielding them from environmental factors like moisture, sunlight, dust, and regular wear and tear. It helps prevent structural damage, corrosion, and deterioration, extending the lifespan of various components in the facility, including walls, floors, metal structures, and equipment.
Maintenance and Preservation: Regular painting operations are part of preventive maintenance programs in facility management. By addressing minor issues like peeling, cracks, or stains on surfaces, painting helps maintain a well-maintained and professional appearance. It prevents further damage and the need for costlier repairs in the future. Using environmentally conscious paints contributes to sustainable practices and healthier indoor air quality.
Functional Differentiation: Painted color variations are utilized to differentiate various spaces within a facility. By using different colors, patterns, or textures, specific areas can be designated for different purposes, such as work zones, storage areas, or recreational spaces. This assists with wayfinding and enhances overall functionality.
Today at 15:00 UTCwe review best practice literature for large-scale painting operations — an exploration different than the one undertaken during our Fine Artand Signs, Signs, Signscolloquia — with attention to worker and chemical safety. Among these considerations:
Falls from Heights: When painting large structures such as buildings or bridges, workers often need to work at elevated heights using ladders, scaffolding, or aerial lifts. Falls from heights are a significant hazard, and proper fall protection systems, such as guardrails, harnesses, and safety nets, should be in place to prevent accidents. Large-scale painting operations may require workers to access or work on structures that have structural weaknesses, corroded surfaces, or unstable platforms.
Inhalation of Hazardous Substances: Paints, coatings, solvents, and other chemicals used in large-scale painting operations can release volatile organic compounds (VOCs) and other harmful substances. Prolonged exposure to these chemicals, particularly in poorly ventilated areas, can lead to respiratory problems, dizziness, skin irritation, or other health issues. Proper personal protective equipment (PPE) like respirators, gloves, and protective clothing should be provided and used to minimize exposure risks.
Skin and Eye Irritation: Contact with paint, solvents, or other chemicals can cause skin irritation, dermatitis, or allergic reactions. Splashes or spills can also result in eye injuries. Workers should wear appropriate protective clothing, such as gloves, coveralls, and safety goggles, to protect their skin and eyes from direct contact with hazardous substances.
Fire and Explosion Risks: Some paints and solvents are flammable or combustible, posing fire and explosion risks, especially in enclosed spaces or areas with inadequate ventilation. Strict adherence to fire safety measures, including proper storage and handling of flammable materials, use of spark-proof tools, and implementing effective fire prevention protocols, is crucial.
Weather Conditions: Outdoor large-scale painting operations are often subject to weather conditions, such as extreme temperatures, high winds, or rain. Adverse weather conditions can pose risks to workers’ safety and affect the quality of paint application. Adequate weather monitoring and planning, along with appropriate safety measures and protective equipment, are necessary to mitigate these hazards.

“All Glory, Laud and Honour” is a hymn written by Theodulf of Orléans around 820 AD, originally in Latin as “Gloria, laus et honor.” Composed during his imprisonment in Angers, France, it was meant for Palm Sunday, celebrating Jesus’ triumphal entry into Jerusalem.
The hymn became part of liturgical traditions, sung during processions. Translated into English by John Mason Neale in 1854, it gained widespread use in Anglican and other churches. Its enduring melody, often paired with the text, is attributed to Melchior Teschner (1615). The hymn remains a staple in Christian worship, especially during Holy Week.
Primary Standards: NIST maintains primary color standards, such as spectral reflectance and transmittance standards, that are traceable to international measurement systems.
Calibration of Instruments: Instruments used for color measurement are calibrated using these standards to ensure accuracy and consistency.
2. Instrumentation
Spectrophotometers: These instruments measure the intensity of light at different wavelengths. They are used to obtain the spectral reflectance or transmittance of a sample.
Colorimeters: These are simpler instruments that measure color using a few broad wavelength bands. They are often used for less precise applications.
3. Measurement Process
Sample Preparation: The sample to be measured is prepared according to specific protocols to ensure uniformity and consistency.
Spectral Measurement: The spectrophotometer or colorimeter measures the light reflected or transmitted by the sample across the visible spectrum.
Data Collection: The data collected includes the spectral power distribution, which indicates how much light is reflected or transmitted at each wavelength.
4. Data Analysis
Color Spaces and Models: The raw spectral data is converted into color space coordinates (e.g., CIE XYZ, Lab) using mathematical models. These models account for human vision characteristics and provide a numerical representation of color.
Comparison and Reporting: The measured color can be compared to standard references or reported in various formats depending on the application (e.g., color difference ΔE).
5. Quality Control and Assurance
Repeatability and Reproducibility: NIST ensures the repeatability and reproducibility of color measurements by using rigorous quality control protocols.
Uncertainty Analysis: The uncertainty associated with the measurements is analyzed and reported to provide a clear understanding of the precision of the measurements.
Example Instruments and Techniques
Goniospectrophotometers: These measure the color of materials that change appearance with viewing angle.
Integrating Spheres: These are used with spectrophotometers to measure diffuse reflectance or transmittance.
Laser-based Systems: Advanced systems that use lasers for highly precise color measurements.
NIST’s methods are designed to provide highly accurate and reliable color measurements that can be used across a wide range of industries, including manufacturing, textiles, and digital imaging.
Colours determine our lives – consciously and subconsciously. They give us direction, influence our emotions, act as a means of communication, underline individuality and give us our identity. RAL colours have existed in all areas of our lives for decades and they set the colour standards for clear global communication of colour in architecture, design, skilled trades and industry.
Enter into the three RAL colour ranges with over 2,500 clearly specified shades for professional colour design. Find out on our website about our colour collections, our analogue and digital products as well as the latest trends from the world of RAL colours.
NFPA 1 Fire Code does not have a specific section dedicated solely to painting facility safety. However, there are several sections within NFPA 1 that address fire safety requirements relevant to painting facilities. These sections provide guidelines and standards for various aspects of fire prevention and protection. Here are some key sections within NFPA 1 that are relevant to painting facility safety:
Chapter 10: Hazardous Materials: This chapter outlines requirements for the storage, handling, and use of hazardous materials, including paints, solvents, and flammable liquids. It covers topics such as storage limitations, ventilation, spill control, and fire protection measures.
Chapter 13: Spraying, Dipping, and Coating Using Flammable or Combustible Materials: This chapter addresses specific fire safety requirements for spray booths, spray rooms, and dip tanks used in painting and coating operations. It covers aspects such as construction, ventilation, electrical equipment, ignition sources, and fire suppression systems.
Chapter 15: Spraying and Dipping Operations: This chapter provides general requirements for spray finishing operations, including safety precautions, ventilation, electrical equipment, and handling of flammable or combustible materials.
Chapter 16: Combustible Dust-Producing Operations: While not specific to painting, this chapter is important for facilities that generate combustible dust during surface preparation or other operations. It addresses fire and explosion hazards associated with combustible dust, providing requirements for dust control, ventilation, equipment, and other safety measures.
These sections highlight key areas within NFPA 1 that can guide painting facility safety. It is essential to consult the latest edition of NFPA 1 and any applicable local or state fire codes to ensure compliance with the most up-to-date requirements and regulations specific to your location and facility type.

Many people are surprised to learn what counts as a “drink”. The amount of liquid in your glass, can, or bottle does not necessarily match up to how much alcohol is actually in your drink. Even before the United States federal government withdrew from regulating alcohol, the conversation, and degree of agreement and attitude, remains remarkably regionally specific:
