When disaster strikes, such as during a fire, the environment can quickly become chaotic and disorienting. Thick smoke, power failures, and the stress of an emergency situation can make it difficult for occupants to find their way to safety. This is where luminescent lighting plays a crucial role in fire safety, guiding people to exits and ensuring that evacuation routes are clearly visible.
When it comes to safeguarding your business from potential fire hazards, a comprehensive emergency preparedness plan is essential. Among the various safety measures, fire cabinets play a pivotal role in ensuring that your business is equipped to handle emergencies efficiently. In this blog, we’ll explore how fire cabinets fit into a broader strategy for emergency preparedness and response.
When it comes to enhancing safety and sustainability in commercial buildings, smoke vents are essential. They provide a means to control and vent smoke during a fire, improving evacuation safety and aiding firefighting efforts. However, not all smoke vents are created equal. While traditional smoke vents serve their purpose effectively, commercial daylighting smoke vents offer additional benefits that can significantly enhance the functionality and value of a building. In this blog, we explore the advantages of commercial daylighting smoke vents over regular smoke vents.
Photoluminescent pigments are materials that absorb energy from light and then re-emit that energy as visible light, creating a glow-in-the-dark effect. These pigments are commonly used in safety applications, such as emergency signs, and can be mixed with various materials like paint, plastic, ceramics, glass, and fibers. The pigments are not radioactive or toxic, making them a safe and sustainable choice for a wide range of applications.
Photoluminescent pigments contain inorganic chemical compounds, typically composed of aggregated crystal elements. When exposed to light, these compounds absorb energy and then release it over time as a glowing effect. The pigments can absorb a wide spectrum of visible light and re-emit it, allowing them to "charge" under different lighting conditions and glow in the dark without the need for electrical power.
Photoluminescent technology has evolved over the decades. In the 1970s, phosphorous pigments were used to create safety markings, but they had limited absorption capacity and required electric power to boost their glow. In the 1980s, stronger pigments made of zinc sulfide crystals were developed. However, the real breakthrough came in the 1990s with the introduction of strontium aluminate powder, which could fully charge in about 20 minutes and provide light for more than 10 hours. These advancements have made photoluminescent pigments more efficient and effective in various applications.
To understand how photoluminescent pigments perform, it's helpful to know a few key terms related to light and brightness:
Lumens are typically measured using an integrating sphere, which calculates the total light output in all directions. Millicandela, however, is highly dependent on the angle at which the light is emitted, which is why high-brightness LEDs designed for illumination are typically measured in lumens, while indication LEDs are measured in millicandela.
The type of light used to charge photoluminescent pigments affects their performance. Fluorescent, LED, and halogen lights are more effective than incandescent bulbs because they produce more light and less heat. Sunlight can also be used, but it may cause signs and labels to fade over time.
Proximity to the light source also plays a role in how effectively photoluminescent materials charge. The closer the material is to the light source, the more light it absorbs, resulting in a brighter glow. As few as 5 foot-candles of light (equivalent to a 15-watt bulb) can be used to charge photoluminescent labels and signs.
The National Fire Protection Association (NFPA) requires that photoluminescent exit enclosures be continuously illuminated for at least 60 minutes before a building is occupied. This ensures that the markings have time to fully charge and provide adequate illumination during emergencies.
Under typical stairwell lighting, photoluminescent signs and labels can take 30 to 60 minutes to fully recharge and then emit a steady glow for about eight hours. This provides a reliable source of illumination during power outages or emergencies, enhancing safety and compliance with building codes.
Photoluminescent pigments offer a versatile and energy-efficient solution for glow-in-the-dark applications. Their ability to gather energy from light and re-emit it without the need for electricity makes them a valuable resource in safety and other industries. Understanding how they work and the factors that affect their performance can help you make informed decisions about using them in your projects.
Photoluminescent egress path marking systems are an important life safety requirement in current building codes. These systems allow for the safe and quick evacuation of buildings in the case of an emergency. They provide a routing system that is not dependent on electrical power that can easily be followed in dark and smoke-filled exit pathways. Nystrom offers a full line of photoluminescent products.

In industrial and commercial environments, ensuring safety is paramount. Fire safety cabinets play a crucial role in protecting flammable and hazardous materials from fire risks. However, not all fire safety cabinets are created equal, and choosing the right one for your needs can be daunting. This guide will help you understand the key differences between fire safety cabinets to make an informed decision.
In the realm of commercial building design, the integration of fire safety measures is paramount to protect occupants and property in the event of emergencies. One critical component of fire safety systems is smoke vents, which facilitate the safe evacuation of occupants and aid firefighting efforts. In recent years, thermally broken smoke vent products have emerged as innovative solutions that not only enhance fire safety but also contribute to energy efficiency and building performance. In this blog, we'll explore the benefits of thermally broken smoke vent products and their significance in commercial building design.
Access doors are crucial components in various architectural and construction projects, providing convenient and secure entry points to enclosed spaces such as utility closets, crawl spaces, attics, and mechanical rooms. Their role extends beyond mere functionality, often contributing to the overall safety, security, and efficiency of a building or structure.
Commercial spaces demand versatile solutions, and when it comes to accessing utility vaults, crawlspaces, or storage areas beneath the floor, the choice of floor doors and hatches becomes crucial. In this comprehensive guide, we delve into the intricacies of various types, exploring their applications and emphasizing compliance with international building codes and fire safety standards.
Whether at home, in the car, boat, work or school, you’ll find fire extinguishers ubiquitous with good reason. According to the National Fire Protection Agency, code 10, the maximum travel distance to an extinguisher in a commercial building is 75 feet, emphasizing their crucial role. Knowing how to select the appropriate extinguisher is critical.
As early as 1897, the National Fire Protection Agency (NFPA) has been addressing fire life and safety concerns. Currently, NFPA 80 is the standard for fire doors and other opening protectives. Chapter 16 of NFPA 80 is designated for access doors in both horizontal and vertical applications in fire-rated walls, floors, and floor-ceiling or roof-ceiling assemblies (NFPA 2022). This article addresses common uses, styles and specification tips for fire-rated floor doors and access doors.
