Emergency Lighting Design

The British Standard BS 5266-1 provides comprehensive guidelines for the design, installation, and maintenance of emergency lighting systems. These standards are crucial for ensuring safety in buildings during emergencies, such as power outages or fires.

Key aspects covered by these standards include:

System Design and Installation: The design process should ensure system integrity to guarantee that emergency lighting will be provided when required. This includes considering the potential failure of standard lighting and the emergency lighting luminaires, as well as determining the mounting height and spacing between luminaires. The installation should follow a thorough design plan to ensure the system is appropriate for the building.

Types of Emergency Lighting Systems: BS 5266 classifies emergency lighting into various types based on their intended use and operational requirements, including escape route lighting, open area lighting, standby lighting, high-risk task area lighting, escape sign lighting, open area anti-panic lighting, and emergency safety lighting for standby lighting. Each type is designed for specific scenarios within a building, from illuminating escape routes to providing lighting in high-risk areas.

Maintenance and Testing: Regular testing and maintenance are essential to ensure the reliability and functionality of the emergency lighting system. Routine inspections should include monthly functional operation checks and annual full-duration tests of each luminaire. It's also important to keep detailed records of all tests and repairs in a logbook.

Legal and Safety Requirements: Emergency lighting is required in the UK for various reasons, including ensuring the safety of building occupants, compliance with legal requirements such as the Regulatory Reform (Fire Safety) Order 2005, and adherence to health and safety regulations. It's also crucial for avoiding liability in case of emergencies.

Classification and Siting of Luminaires: The BS 5266 standard replaces the old classification system with a more detailed code consisting of type, mode of operation, facilities, and duration. This helps in precisely categorizing emergency lighting systems. Additionally, careful consideration should be given to the siting of emergency lighting units and signs within a building to ensure safety and compliance.

For detailed information and specific guidelines, you can refer to the official documents of the BS 5266 standard provided by the British Standards Institution and other related sources. It's also advisable to consult with certified professionals to ensure compliance with current regulations and standards.
