Green Vs. Red: What Color Do Exit Signs Need To Be

When it comes to safety in buildings, every detail matters, especially the color of exit signs. The debate between using green vs red exit signs is not just a matter of aesthetic preference but involves considerations of visibility, psychological impact, and international standards. This blog post aims to explore the factors that contribute to the choice of color for exit signs, offering insights into why this decision is crucial for ensuring safety in emergencies.

Understanding the Importance of Exit Sign Colors

Exit signs play a pivotal role in emergency evacuation plans. They are designed to guide occupants to safety in a clear, unambiguous manner. The color of these signs is a key component in ensuring they are visible and universally understood, regardless of language barriers. Historically, red has been the dominant color for exit signs in many parts of the world, particularly in the United States. However, green exit signs have become increasingly common, especially in European and Asian countries, due to their alignment with international standards and research findings on human psychology and visibility.

The Case for Green Exit Signs

  • Enhanced Visibility

Studies have shown that the human eye is more sensitive to green wavelengths of light compared to red. This increased sensitivity can make green exit signs easier to spot, especially in smoky or poorly lit conditions. Green also offers higher luminance, which contributes to its effectiveness in capturing attention quickly in an emergency.

  • Psychological Impact

Green is universally associated with safety, go, and forward movement. This psychological association can have a calming effect on individuals during stressful situations, guiding them towards exits more efficiently. The use of green exit signs leverages these associations to enhance the effectiveness of emergency evacuation procedures.

  • Alignment with International Standards

The International Organization for Standardization (ISO) recommends the color green for safety signs, including exit signs. This recommendation is based on the premise that green signs are more intuitively linked to safety and egress. Adopting green exit signs can help create a uniform approach to emergency signage, facilitating easier understanding and recognition across different countries and cultures.

The Case for Red Exit Signs

  • Historical Precedence and Familiarity

In many regions, especially in North America, red has been the traditional color for exit signs for decades. This long-standing use has led to a high level of familiarity among the population, potentially aiding recognition due to habitual exposure. The argument for keeping red exit signs often hinges on the concern that a sudden switch to green could confuse occupants accustomed to looking for red in emergencies.

  • Regulatory Requirements

In some jurisdictions, the choice of exit sign color is not up for debate but dictated by local building codes and regulations. These laws are often based on historical standards and practices, making red exit signs a requirement rather than a choice. Compliance with these regulations is crucial for building owners to avoid legal and insurance complications.

Operational Considerations in Exit Signage

  • Visibility in Various Conditions

The operational effectiveness of exit signs, regardless of their color, is paramount. This includes their visibility in smoke-filled environments, during power outages, and under emergency lighting conditions. Modern exit signs are equipped with LED technology, ensuring they remain illuminated and visible even when traditional power sources fail. The choice between green and red exit signs should also consider these operational aspects to ensure maximum effectiveness during an emergency.

  • Energy Efficiency and Sustainability

Sustainability and energy efficiency are increasingly important considerations for building operations. LED exit signs, whether green or red, offer significant advantages over older incandescent or fluorescent signs, consuming less power and requiring less maintenance over their lifespan. This contributes to a building's overall energy efficiency and sustainability goals, aligning with global efforts to reduce energy consumption and environmental impact.

  • Compliance and Legal Implications

Adhering to local building codes and international safety standards is crucial when installing exit signs. The legal implications of non-compliance can be severe, including fines, legal action, and potentially jeopardizing the safety of occupants. It's vital to stay informed about the specific requirements in your jurisdiction and any changes to international standards that may affect your obligations.
