The first study completed in 1999 was designed to assess the potential use of PLM as a safety communication system to support office occupant evacuation. The study measured the occupant premovement time, movement time and evacuation speed in four stairways with different lighting and PLM installations. The positive outcome of the first study regarding a comparable speed of movement in the different stairways used and the conclusive feedback from the evacuees regarding the PLM wayguidance system led to a second study. The second study, completed in 2008, compared 3 stairway installations of PLM markings and a stairway with emergency lighting, which acted as a reference stairway. Results show comparable speed of movement under severe crowd conditions for the 4 stairways studied. Overall, two-thirds of the respondents felt comfortable going down the stairways with PLM markings particularly in the 2 stairways where the marking was installed across each step. The stairway, which had only emergency lighting, and the stairway with L-shaped markers at the edge of each step were less appreciated by the occupants. Occupants commented that the landings and mid-landings were difficult to identify in all the stairways, which suggest that additional marking should be provided in these areas. The findings of these two studies led to the development of a best practice Guide for installation of PLM marking in exit stairways.
