Poor visibility significantly increases the risk of accidents, while fixtures that cannot withstand high temperatures fail quickly, thereby creating dangerous situations. In this article, we answer the most frequently asked questions about lighting, occupational safety, and extreme heat, from the risks to the most suitable solutions.<\/p>\n<h2>What risks arise from poor lighting in hot environments?<\/h2>\n<p>In hot industrial environments, inadequate lighting directly increases the risk of serious occupational accidents. Operators fail to see dangerous situations\u2014such as moving machinery, hot surfaces, or glowing material\u2014too late or not at all. This leads to a higher risk of collisions, falls, and contact injuries with hot objects.<\/p>\n<p>What makes this problem extra difficult: in environments with high heat, smoke, or steam, visibility is already naturally limited. When the lighting is also insufficient or flickers irregularly due to overheating, the risks pile up. Employees working near high-temperature installations, crucibles, or foundries need reliable, bright light to do their work safely.<\/p>\n<p>Specific risks of poor lighting in hot environments include:<\/p>\n<ul>\n<li>Insufficient visibility of hot surfaces, liquid metal, or glowing materials<\/li>\n<li>Difficulty distinguishing between safety signs and markings<\/li>\n<li>Fatigue and reduced concentration due to poor contrast and insufficient light intensity<\/li>\n<li>Delayed response time in emergency situations due to hazards not being noticed in time<\/li>\n<li>Increased risk of tripping or falling due to deep shadows and poor depth perception<\/li>\n<\/ul>\n<p>In short: lighting in these environments is not a luxury, but a basic safety feature that directly impacts employee well-being.<\/p>\n<h2>How does extreme heat affect the performance of lighting fixtures?<\/h2>\n<p>Extreme heat affects the performance of lighting fixtures in multiple ways. LED components are sensitive to high ambient temperatures: when the temperature around the fixture gets too high, the light output decreases, the wear and tear on the light source accelerates, and the fixture can fail prematurely. This phenomenon is called thermal degradation.<\/p>\n<p>Standard LED luminaires are typically designed for ambient temperatures up to a maximum of 40 to 50 degrees Celsius. In steel mills, foundries, or near blast furnaces, however, temperatures around the luminaire can rise well above 100 degrees Celsius, especially when there is also intense infrared radiation. Under those conditions, conventional lighting simply falls short.<\/p>\n<p>In addition to temperature, other factors also play a role:<\/p>\n<ul>\n<li>Infrared radiation causing extra heat on the housing<\/li>\n<li>Thermal shocks caused by rapid changes between hot and cold<\/li>\n<li>Dust and metal particles that obstruct the cooling of the luminaire<\/li>\n<li>Vibrations from heavy machinery that shorten component lifespan<\/li>\n<\/ul>\n<p>For reliable operation under such conditions, luminaires are required that are specially designed for <a href=\"https:\/\/jelproducts.nl\/en\/high-temperature-lighting\/\">High-temperature lighting<\/a>, with a housing and cooling system that effectively dissipate heat and are resistant to infrared radiation.<\/p>\n<h2>What are the legal requirements for lighting in hazardous work environments?<\/h2>\n<p>Employers are legally required to provide a safe working environment, and lighting is explicitly a part of that. The Working Conditions Act (Arbowet) obligates employers to ensure sufficient and effective lighting in the workplace, tailored to the nature of the activities and the risks in the environment.<\/p>\n<p>In practice, this means that the illuminance (measured in lux) must be tailored to the visual task requirements of employees. Higher requirements apply to precision work or operating hazardous machinery than to corridors or storage areas. In addition, specific requirements apply to emergency lighting so that employees can evacuate safely even during a power outage.<\/p>\n<p>In environments with a risk of explosion, such as in certain chemical processes or dust-laden industries, additional requirements apply. In such cases, luminaires must comply with ATEX directives, which set requirements for the construction of electrical equipment in explosive atmospheres. The IP rating of a luminaire indicates the extent to which the device is protected against dust and moisture, which, in combination with high temperatures, is a critical selection criterion.<\/p>\n<h2>Which lighting solutions are suitable for steel mills and foundries?<\/h2>\n<p>In steel mills and foundries, special high-temperature LED fixtures are required that can withstand intense heat, infrared radiation, and heavy mechanical stress. Standard industrial lighting is insufficient here. The fixtures must be able to operate at ambient temperatures that can reach up to 120 degrees Celsius or more.<\/p>\n<p>When selecting suitable lighting for these environments, the following steps are important:<\/p>\n<ol>\n<li><strong>Map the thermal load:<\/strong> Determine the maximum ambient temperature and the degree of infrared radiation at the installation location.<\/li>\n<li><strong>Choose fixtures with an appropriate temperature resistance:<\/strong> Select luminaires that have been verified to have been tested for the relevant temperature class.<\/li>\n<li><strong>Pay attention to the IP rating:<\/strong> Dust and metal particles are ubiquitous in foundries and steel mills; a high IP rating prevents contamination of the optics and electronics.<\/li>\n<li><strong>Account for vibrations:<\/strong> Heavy machinery causes constant vibrations; choose fixtures with robust mounting and shock-resistant components.<\/li>\n<li><strong>Plan the maintenance realistically:<\/strong> In these environments, luminaires are often difficult to access; opt for a long lifespan and minimal maintenance requirements.<\/li>\n<\/ol>\n<p>Floodlights and work lamps specifically developed for heavy industry combine all these features. They offer a high light output, stable operation under extreme conditions, and a housing that is resistant to the aggressive environment of a steel mill or foundry.<\/p>\n<h2>How does good lighting improve productivity and safety at the same time?<\/h2>\n<p>Good lighting increases both safety and productivity because employees can work better and faster without unnecessary mistakes or dangerous situations. Adequate light intensity, the correct light color, and a good distribution without deep shadows ensure that people can perform their work more accurately and faster.<\/p>\n<p>In hot industrial environments, this effect is even more noticeable. Employees working in high temperatures already deal with physical stress. If the lighting is also poor, the mental load increases further. Bright, uniform light reduces the cognitive effort required to recognize hazards and perform tasks correctly.<\/p>\n<p>In practical terms, good industrial lighting delivers the following:<\/p>\n<ul>\n<li>Less downtime due to failed luminaires or forced repairs<\/li>\n<li>Faster and more accurate execution of tasks, even with complex operations<\/li>\n<li>Fewer errors when reading meters, screens and safety signaling<\/li>\n<li>Higher alertness among employees due to less visual fatigue<\/li>\n<\/ul>\n<p>The investment in high-quality lighting pays for itself through lower maintenance costs, fewer failures, and a better working environment. For a good overview of the possibilities per sector, it is useful to look at the <a href=\"https:\/\/jelproducts.nl\/en\/sectors\/heavy-industry-extreme-heat\/\">heavy industry applications<\/a> and the specific requirements that apply there.<\/p>\n<h2>Practical example: High-Temperature Industry at Rockwool<\/h2>\n<p>A striking example of the challenges surrounding lighting and occupational safety during extreme heat is the project at Rockwool. In Rockwool's production environment, mineral wool fibers are produced at extremely high process temperatures. The ambient temperature around the installations is structurally high, and the infrared radiation from the production processes places a heavy burden on the luminaires.<\/p>\n<p>The technical challenge was clear: standard industrial LED fixtures could not handle the conditions. Fixtures that were not designed for this type of thermal load quickly showed light degradation, failure, or even physical damage to the housing. This led to unsafe situations on the work floor and high maintenance costs due to frequent replacements.<\/p>\n<p>The solution lay in deploying specially developed high-temperature fixtures with a housing that actively dissipates heat and is resistant to prolonged exposure to high ambient temperatures and infrared radiation. The fixtures were positioned in such a way that the thermal load at the installation locations remained as low as possible, without sacrificing the required illuminance for safe working.<\/p>\n<p>The lesson learned from this project is directly applicable to similar situations: a good thermal analysis of the installation location is just as important as the choice of the luminaire itself. Anyone who only looks at lumen values and IP ratings misses a crucial part of the lighting strategy in hot environments.
