3.1 Public spaces

  3.1.1 If the system is intended to be installed in public spaces, the test facility should be designed so that participants are required to navigate to a pre-designated exit across a public space, where the shortest distance to that exit is not along a wall. A minimum of two exits should be provided to test the ability of participants to identify and proceed to an exit within an open space. An additional fail exit should be located 2 to 3 m from each correct exit.

  3.1.2 The test room should be not less than 15 m by 10 m with the start point and pre-designated exit being on the long sides, diagonally opposite each other, such that the distance around the walls is approximately equal in either direction. The density of the smoke should be great enough to prevent a participant from being able to see no more than half to two-thirds of the distance to the nearest exit OD 0.1 m-1. Direct distance between start and a correct exit should be not less than 12 m.
