The revised BS EN 1838:2013 Lighting applications. Emergency lighting specifies the luminous requirements for emergency escape lighting and standby lighting systems where the public or workers have access.
The standard looks into the implications of the changes to lighting requirements, particularly the removal of the UK A deviations and the changes to requirements for the illumination of exit signs, first aid boxes, fire alarm panels, and call points.
Emergency lighting is needed when the power supply to the normal lighting fails and is therefore powered from a source independent of that supplying the normal lighting. It is essential that exits are clearly signposted and are visible, wherever the location is occupied.
BS EN 1838 should be used in conjunction with BS 5266-1:2011 Emergency lighting. Code of practice for the emergency escape lighting of premises. BS 5266-1 provides guidance on the requirements, procedures, and information that lighting designers should use to evaluate and upgrade existing installations.
