The signs mark the location of manholes and provide relevant technical information: the type of underground communications, diameter of the well, distance to the manhole, etc.
The signs are made of a composite material covered with ORACAL film. The result is a sign that looks great on any city building.
To improve visual association, manhole covers are painted to match the color of the signs. Bright paint and white outline will show car drivers where to avoid parking.
Signs of manholes containing fire valves are located 2–3 meters (6–10′) above the ground where they will be easily seen by firetruck drivers. Signs denoting gas pipeline inspection manholes are located at foot level.
