HELP & ASSISTANCE WHEN SPECIFYING EMERGENCY LIGHTING Emergency Escape Lighting To provide visibility for evacuation purposes lighting is required in the volume of the space. In this standard the recommendation is filled by the mounting of luminaires at least 2m above the floor. Signs which are provided at all exits intended to be used in an emergency and along escape routes shall be illuminated to indicate unambiguously the route of escape to a point of safety. Where direct sight of an emergency exit is not possible, an illuminated directional sign (or series of signs) shall be provided to assist progression towards the emergency exit. An escape lighting luminaire complying with EN 6059-2-22 shall be sited to provide appropriate illuminance near each exit door and at positions where it is necessary to emphasise potential danger or safety equipment. The positions to be emphasised shall include the following (see opposite page): • At each exit door intended to be used in an emergency • Near stairs so that each flight of stairs receives direct light • Near any other change in level • Mandatory emergency exits and safety signs • At each change of direction • At each intersection of corridors
• Outside and near to each final exit • High risk task areas Various specific locations now require additional emergency illumination: 5 Lux - Refuge Areas, Panic Bars, Swimming Pool Areas 15 Lux - Kitchens, First Aid Rooms, Plant Rooms, Fire Alarm Control Equipment, Reception Areas 50 Lux - Treatment Rooms
Escape Route Lighting • For escape routes up to 2m in width, the horizontal illuminances on the floor along the centre line of an escape route shall be not less than 1 Ix and the central band consisting of not less than half of the width of the route shall be illuminated to a minimum of 50% of that value.
Open Area (Anti-Panic) Lighting • The horizontal illuminance shall be not less than 0.5 Ix at the floor level of the empty core area which excludes a border of 0.5 m of the perimeter of the area. • High risk task areas
