High-Visibility Escape Guides
Emergency escape signs should be placed at low-level because signs at or above the top of doors will not be visible by someone crawling on the deck under smoke. It is a good idea to put high-visibility strips along the bottom of bulkheads to highlight corridors in the event of an emergency.
The images also demonstrate the state of visibility in a smokey environment and the advantage of using these strips. If used, it is important that the strips do not guide you past exits, which should be highlighted as demonstrated. The pictures also show how these strips could be used on stairways.
