Luminous egress path markings are a type of safety feature that is often used on stairwells in buildings. These markings are typically made of a material that glows in the dark, so they can be seen even in low light or power outage situations. The purpose of these markings is to provide a clear and visible path for people to follow when they are evacuating a building in an emergency. The markings are typically applied to the walls or floors of the stairwell and are designed to guide people to the exits in a clear and organized manner. This can help people to quickly and safely evacuate the building, reducing the risk of injury or confusion during an emergency situation.
