Excavations are carried out in the daytime to the extent possible. If this cannot be done, the excavation area is illuminated to see the work to be done and the dangers in the area. A lighting system is installed that will be activated against power failure. A flashing lighting system is placed on the edge of public access roads. Appropriate and adequate lighting is made in the excavation area. Access routes are specified so that they do not create glare or deep shadow. The lighting system is protected to prevent damage. A light reflector is placed in the excavations at a distance of 5 meters from the highway. |
