The Royal Decree 635/2006
and the European Directive 2004/54
, on minimum safety requirements in road tunnels
in Spain and the trans-European road network respectively, establish the minimum equipment that a tunnel must include according to its type. These are classified according to whether they are unidirectional or bidirectional, their length and their Average Daily Traffic (ADT).
1. Emergency exits. Large-format evacuation signage, which thanks to its photoluminescence and large dimensions helps to identify the emergency exit from long distances and/or under unfavorable conditions, such as darkness, smoke, or crowds. There are also 'Emergency Exits' lights, in the form of photoluminescent banners. They are internally illuminated and are visible on both sides. In this way, they allow the identification of the emergency exit door. The Emergency Door identification signaling, also photoluminescent, is located on the lintel of the emergency exit.
2. Signaling of the nearest doors. Implaser manufactures photoluminescent signs for the identification of the two closest emergency exits, to the right and left. They indicate the distance, in meters, to the nearest emergency exits, in both directions.
3. Emergency posts. In road tunnels, the existence of signaling sets is mandatory to warn about the presence of a SOS post. They consist of a telephone pictogram, a fire extinguisher pictogram and an arrow indicating the distance in meters to the nearest SOS post, both in the direction of travel and in the opposite direction. In addition to the signage "This area does not protect from fire".
