Knowing that seconds can mean the difference between life and death in crisis situations, fast egress speed is the goal.
Photo luminescent guidance lines do exactly what their name implies. “they guide people out of buildings to safety.”
They give evacuees a visual understanding of the perimeter of the space along a defined exit path, leading to confidence of movement which in turn results in fast egress speeds.
Low located perimeter lines are placed on walls near the floor or on the floor to visually define the space. Also likely to be more visible in smoke-dense conditions
Large Breaks must be avoided because they send a visual cue to evacuees that may give them a pause to consider whether or not to go through the break in the line.
Except for incline or decline on steps perimeter guidance lines must be “continuous.” Breaks No more than 4” are allowed. Unless otherwise owing to site condition.
Placement of guidance lines at a height (3-4’ high on the wall) can be considered as an additional element to visually define the escape path.
Though technically not the guidance lines, the same materials are used to outline all doors that must be gone through on the escape path, including the final exit door.
The mandatory marking of all the push bar door opening mechanisms can also use the same materials.
Step Markings as the name suggests are used to ensure that foot landing edges are easily understood by the evacuee
Step Handrails are marked with lines to give evacuees a clear idea of where to place their hands. These lines also serve to define the space going down the stairwell.
