The orientation markers are placed from a height of 2 meters (6.5 feet), as this area is available in most schools and is unobstructed in an emergency. The signs in the crowd could be at the height of the breast.
The square wall marker marks the building color and the direction of the next building part.
Furthermore, the stairwells and entrances are specially marked, which primarily serves the rescue forces when they enter the stairs or entrance area from the outside. This makes the orientation and communication between the parties considerably easier.
