Title Movement under emergency lighting: the effect of illuminance
Bibliographic information 1985, Vol.17, No.2, p.51-71. Illus. 12 ref.
Abstract An investigation was carried out in a large open-plan office with the aim of identifying the illuminance necessary for rapid, safe movement under emergency lighting conditions. At a mean illuminance of 0.2lx, the test subjects had difficulty in moving quickly over the escape route. Optimum illuminance for quick and orderly evacuation was established at 1lx. It seems that the prsent emergency lighting criterion of 0.2lx used in the United Kingdom should be revised and the 1lx standard adopted.
