The SN EN 1838:2025 is a crucial standard published by the Swiss Association for Standardization (SNV), focusing on the technical requirements for emergency lighting systems in buildings to ensure safety and compliance in public and workplace environments.

Purpose and objectives

The primary objective of the SN EN 1838:2025 standard is to establish safety protocols for emergency lighting systems. It aims to ensure that adequate illumination is provided in emergency situations, facilitating safe evacuation and minimizing panic. This standard outlines specific requirements for various types of emergency lighting, including safety lighting for escape routes, anti-panic lighting, and illumination for high-risk task areas. By implementing these guidelines, organizations can improve public safety and ensure compliance with legal requirements, ultimately enhancing the overall emergency preparedness of buildings.

Scope: who must comply

The SN EN 1838:2025 standard applies to a wide range of stakeholders involved in the construction and management of buildings accessible to the public and workers. This includes:

• Architects and designers who plan emergency lighting systems.
• Building owners and facility managers responsible for maintaining compliance.
• Construction professionals involved in the installation of lighting systems.
• Regulatory bodies that enforce safety regulations in public spaces. Typical industries include healthcare, education, hospitality, and any commercial spaces where public access is essential, particularly in areas classified as high-risk.

How SN EN 1838:2025 relates to other standards

The SN EN 1838:2025 standard complements several other standards in the field of emergency lighting and safety, including:

• EN 1838:2024, which serves as a foundational standard for emergency lighting in buildings, providing detailed specifications on performance criteria.
• ISO 7010, which provides universally recognized safety signs and symbols, crucial for effective communication during emergencies.
• CEN standards, which outline broader European safety regulations, ensuring harmonization across member states.

Revision history and current status

The SN EN 1838:2025 is the latest revision published by the Swiss Association for Standardization (SNV). This revision includes updates to reflect technological advancements in lighting systems, enhanced guidelines for specific high-risk areas, and improved specifications for luminance and illuminance measurements. These changes aim to ensure that the standard remains relevant and effective in enhancing safety in modern building designs.
