British Standard BS 5266-1:2016 is a code of practice for emergency lighting in buildings. It provides guidance on the design, installation, commissioning and maintenance of emergency lighting systems in order to ensure the safety of occupants during an emergency situation.
The standard applies to all non-domestic buildings, including offices, factories, shops, hotels, public buildings and other premises where people are likely to be present. It is important to note that compliance with the standard is not mandatory, but it is highly recommended in order to meet legal obligations for building safety.
The standard outlines the following key requirements:
Minimum Illumination Levels
BS 5266-1:2016 specifies the minimum illumination levels required in emergency lighting systems in order to ensure safe evacuation. The standard states that a minimum of 1 lux should be provided at ground level in escape routes, and 0.5 lux in open areas.
Types of Luminaires
The standard outlines the types of luminaires that should be used in emergency lighting systems, including bulkhead fittings, recessed fittings and exit signs. The luminaires must be designed to provide adequate illumination and be compliant with relevant safety standards.
Location of Luminaires
BS 5266-1:2016 provides guidance on the location of luminaires in order to ensure that they are positioned correctly and provide adequate coverage in the event of an emergency. The standard outlines the locations where luminaires should be installed, such as escape routes, open areas and high-risk areas.
Duration of Illumination
The standard specifies that emergency lighting systems should be capable of providing illumination for a minimum of three hours in the event of a power failure. This ensures that occupants have sufficient time to evacuate the building safely.
Testing and Maintenance
BS 5266-1:2016 requires that emergency lighting systems are regularly tested and maintained in order to ensure their effectiveness. This includes monthly function tests and annual full discharge tests, as well as regular visual inspections.
In summary, British Standard BS 5266-1:2016 provides essential guidance for the design, installation, commissioning and maintenance of emergency lighting systems in buildings. Compliance with the standard is highly recommended in order to ensure the safety of occupants during an emergency situation.
