Night time lighting of public shelter/evacuation center.

broadgage

Is there any guidance as to what level of overnight lighting should be provided in an indoor sports hall if this be used for emergency overnight shelter/sleeping after some emergency.

The existing lighting is T8 fluorescent and gives three switch selectable lighting levels, but the lowest of these is clearly very excessive if people are sleeping, whereas total darkness clearly carries risk of trips, falls, and other accidents.

I was thinking about providing two levels, 10 lux initially and then 1 lux. I lux is several times that provided by moonlight and “sounds about right” But is there any better guidance than me thinking “that sounds about right.”

10 lux being provided as an intermediate level between daytime lighting and overnight lighting.

    “There were more night raids during January 1941. We had no shelter ourselves, nor was there a street shelter nearby, but a neighbour three doors away had asked us to share theirs during the daylight raids. This offer was repeated when the Blitz got going. Every night I had to hurry home from school, eat my tea, and try to finish my homework before the siren went. Bombers usually arrived about seven pm. My school was seven miles away from my house so I was rarely home before five pm. The evenings were a rush followed by hours of forced idleness sitting in a cold damp shelter lit only by a couple of tiny paraffin lamps. Often I had to learn poetry but could hardly see to read it.”
