Emergency Escape Route Lighting.

Zoomup
Subject: Emergency light over spiral stairs.


A first floor flat has an external spiral steel stairway from the ground to the entrance door. The door opens onto a small platform at the top of the spiral stairway. The flat is to be let.


Would you install an emergency escape light over the door at high level, or half way down from the top of the door to one side of the door, say at eye level,  or at a low level just above the platform. The third option also benefits another escape route from the main house at ground level and illuminates the spiral stairs somewhat.


Note. The sides of the spiral stairs are open except for well spaced spindles. Light can get through the sides.

    The old brick type emergency lights with internal battery and 8 Watt tube provided light at nearly 180 degrees from the tube. So if wall mounted they shone downwards to a certain level. They were best ceiling mounted for illuminating passageways etc. Outside in the cold they could take a while to provide a full bright light output The tubes could blacken over a relatively short time period.


    L.E.D. brick type emergency lights provide a more directional light so are best suited to being ceiling mounted and shining downwards. They provide less sideways light. My viewpoint is that the surface being walked on needs the best illumination, (the exit route) that is why I sited my emergency light low down near to the platform of the spiral stairs. Being to the side of the door it is unlikely to dazzle.
